Incest/Taboo Jason's problem

The early morning sun filled the bedroom, causing Kelly to wake up. Her pussy felt all crusty from Jason's dried cumshots she had received the previous day. She wondered what she was doing. She knew their relationship had forever changed. She allowed her son not just to penetrate her for medical reasons, but to ejaculate in her pussy! What was worse, she allowed herself to become lost and orgasm twice! She orgasmed with her own son in front of Dr. Wood! Fortunately Dr. Wood had offered reassurance and encouragement, saying that her orgasms were very useful for Jason's cock head because in this way she produced more juices. She was very confused, but also she was so aroused! She felt her pussy begin to throb and fluids begin to overflow her swollen vagina lips. Kelly didn't realize yet that she had transformed into a wanton woman full of lust. She didn't want to think about it anymore, so she went to the bathroom. She decided she really needed a shower to get the sperm and sweat off and get really ready for Jason.

Just when Kelly finished her shower and rinsed her hair, she heard Dr. Wood call her name. Apparently, Dr. Wood had already arrived for the morning session, so Kelly quickly wiped herself dry and wrapped her naked body with only a small towel.

"Good morning mom," Dr. Wood greeted her with a smile, when she walked to the living room, "You look so sexy in that small towel!"

"Oh, I'm showing everything," Kelly thought and blushed. She tried to fit her large breasts and pussy into the towel but, no matter how hard she tried, it was impossible. Eventually, she answered, "Oh thanks, Dr. Wood."

"How are you feeling, sweetheart?" Dr. Wood questioned.

"I'm fine, thanks to you," Kelly responded and added, "Thanks for your support. I really hope this works out."

"Of course, sweetie. Trust me, you're doing the right thing for both of you, so stop being so embarrassed and shy," Dr. Wood calmed her.

"I will try... I will try my best to help my son any way I can," Kelly answered with more confidence than Dr. Wood expected.

"I'm glad to hear that," Dr. Wood smiled and enquired further, "How is your pussy after the stretching twice yesterday? Is it sore?"

Kelly blushed crimson with embarrassment, and managed to reply, "Uhhh... no, no! I mean, errr... My pussy... it's fine."

"That's great, Kelly. I was worried because I know you have not had regular sex for a long time. But I'm glad you are one of the girls who love the huge cocks and, more importantly, the stretched feeling," Dr. Wood was pleased.

Kelly blushed again, but it was true, she loved her pussy filled. "Err... however, I have little pain in my low back and hips," she added.

"Oh, muscle soreness was expected due to prolonged interruption in your sexual activity. Don't worry about that," Dr. Wood said and added, "We can start. Where's Jason?"

"He sleeps still," Kelly answered.

"Then we can do a session in his room," Dr. Wood offered.

Kelly nodded and Dr. Wood yelled "Jason, wake up. It's time for your morning session."

Jason woke up and could not believe his eyes. Looking up, he saw his mom standing at the door of his room. The top of the small towel was tucked in between her breasts to secure it around her body and the edge ended just below her pussy. The loose edge of the towel flapped open and closed with the motion of her legs as she walked towards his bed, flashing him an ample amount of bare skin of her hip bone but not quite showing her vulva to his hungry eyes.

"What a way to wake up, huh Jason? I bet you love this, don't you?" Dr. Wood said with a toothy grin, as she casually removed Kelly's towel. Once more his mom stood completely naked before him.

"Yes," Jason said with a sigh. His cock began to grow as he admired his mom's body, so hot and soft. His gaze crossed over her huge full breasts, her round stomach, and swollen intimate parts.

Kelly blushed, but she continued to walk towards him and climbed onto his bed on all fours, slowly coming to be above him.

"Sweetie, this time, I suggest you ride Jason cowgirl style, face to face with him. You look like you've relaxed enough, so there's no need any more to avoid looking each other directly eye-to-eye. I'm sure Jason will enjoy looking at your magnificent tits and particularly your facial expression when you orgasm. Also, it will help to reduce your back pain," Dr. Wood said.

Kelly was in panic, she was humiliated and again felt she had no control. "Not only Jason will be able to see my heavy tits bouncing up and down, but he will be able to see, by the expression on my face, how much pleasure I am receiving from him!" Kelly thought to herself. She was ashamed, but she also realized how horny she was. She tried to reason with herself; it seemed like she was just trying to convince herself she was doing nothing wrong. She pulled back the covers, leaving nothing between Jason's hard cock and her moistened pussy lips. She didn't know what to think, so she squatted on top of him with her feet flat on the bed, her knees bent, letting her legs spread wide and opening herself wide to his view. As she positioned her body against his, she reached down with her right hand, took his hot hard cock and placed the swollen head between the big lips of her dripping pussy. She lowered herself an inch so the head of his cock slipped between her labia.

"Oh mom," Jason groaned, swallowing hard.

Not knowing what to say at this point, Kelly just whispered, "Shhh!" as his cock slid further into her wet opening, causing her to emit a low growl.

"That's a good mommy! Just continue it," Dr. Wood praised her.

Kelly gently lowered herself a bit further, slipping him deeper and deeper inside her, feeling his huge cock stretch her tight walls and pressing against the front wall of her vagina, rubbing against her G-spot.

"Oh, ooh... uhh, uhh... ah ahhh..." Kelly couldn't help but groan hotly. She quickly covered her mouth before another one could escape.

"Tell us, how does it feel?" Dr. Wood urged.

"Mmmm, sooo gooood. He feels so good inside me," Kelly drawled. Judging by the excited reaction from Jason, she knew she shouldn't be saying such things out loud.

"Do you feel any pain in your back now?" Dr. Wood enquired.

"Much smaller, ahhh... a little bit here," Kelly answered bending over and touching her low back.

"This is because of your half-squat position, Kelly. Unfortunately, half squats have been known to cause unwanted low back soreness. If you overarch your lower back, when your hips tip forward and your butt pops out, you're using the muscles of the lower back to keep your spine from rounding forward. So, keep your back flat and drop your hips lower!"

"Lower? But... it means Jason would penetrate me deeper. I can't do that. I'm not able to take something as big as his thing in me," Kelly begged. To her shame, the muscles in her vagina seemed to caress his cock. She tried unsuccessfully to bring her body back under control.

"Contrary to your belief, I'm sure that your big wet pussy is more than capable of taking in his whole cock all the way to his balls. Just relax and push yourself lower into a full-depth squat position. Remember, full-depth squatting is good for your low back. Many cultures including the Asian, African and South American all squat in full-depth squat for hours as a rest position," Dr. Wood reminded. Then she added with smile, "Go ahead, hottie. Get down into a full-depth squat position and your pain will disappeared. And best of all, a full-depth squat will allow you unrestricted range of motion in all directions."

Kelly gasped and started to lower herself as Dr. Wood requested, thinking of what Dr. Wood meant by '... will allow you unrestricted range of motion in all directions'. Each time she pushed in another inch of Jason's long tick cock, she needed some time to relax and adjust... it stung like hell.

His monster girth was only half way inside when Dr. Wood saw the telltale signs that Kelly was close to orgasm. Kelly also felt the huge orgasm approaching and she was angry at herself for giving into her base, animal desires. Her emotional need to maintain her dignity in front of her own son could not compete with her very strong sexual urges, but she tried.

"Ahhh...I think I'm taking all I can...," Kelly lied, mentally trying to avoid orgasm. She didn't move and only kept it in half way.

"Nonsense, mommy! I'm sure you have a big roomy pussy. Also, I know that your vagina is exceedingly elastic and can expand to twice its size when sexually aroused! So, raise up a little and go on," Dr. Wood ordered. She figured that Kelly was close to orgasm and she wanted Kelly to achieve it.

Biting her lip, Kelly first rose up and then lowered herself down again, getting a bit more of Jason's cock inside. Obviously, she was ready for more of his length. However, Kelly was definitely even more ready to explode. After a few seconds Dr. Wood noticed that! She saw the look on Kelly's face and knew she was about to explode in an extremely good orgasm.

"Jason, look up into your mom's face. See her mouth open and her eyes closed tightly! See that look! I think mommy is cumming," Dr. Wood announced with unconcealed pleasure.

Kelly's mouth opened wider, she was gasping as she tried not to groan shamelessly. But her bucking and convulsing left no doubt that it was true. Her head was thrown back now, one hand at her face, her fingers playing at her lips as she breathed heavily. Jason looked at his mom in admiration, feeling her pussy squeezing around his cock.

"Fuck," Jason thought as he felt the extra pressure around his penis. "I can't believe I'm fucking my mom and she's cumming on my cock." Then he remembered what Dr. Wood said yesterday about giving his mom support, so he said softly, "Mom, your pussy is incredible! And you don't need to be ashamed, you know how much I like when you cum on my cock."

Kelly relaxed and moaned with both pleasure and relief, she was grateful for his support.

"Yes, your mom is unbelievable; she can climax so quickly and so powerfully!" Dr. Wood agreed and added, "Go on, hottie! Lower yourself further!" Obviously Dr. Wood didn't want to waste time waiting for Kelly's orgasm to calm down.

Kelly surrendered to the pleasure and Jason watched in amazement while his mom worked her way down on his long cock. She was grinding on it and Dr. Wood knew he was up inside her well past her belly button, opening her up deep inside, stretching her wider and deeper than she'd ever been. Finally, Kelly sat down hard on him and that was it...all of it...she did it! She just sat there into a full-depth squat position, moaning and rolling her head around. Another massive and powerful orgasm hit her, convulsing her entire body. She had such a blissful, lusty expression on her face that Dr. Wood couldn't help but ask her, "Are you ok, sweetie?"

"Ahhh... yessss. I'm sooo full," Kelly barely answered. Her eyes widened with a mixture of disbelief and delight, her mouth opened slightly in pleasant surprise.

Dr. Wood placed a finger under Kelly's chin and tilted her face so she could look into her eyes, "I am quite impressed that you took his huge cock so easily, honey" Dr. Wood said softly.

"I didn't believe I could do it," Kelly answered quietly and averted her gaze. Obviously, she was still shocked that she had done such a thing. She felt betrayed as her body reacted in ways it shouldn't. She didn't want to feel like this. Dr. Wood could easily sense that, but she loved these moments. She loved the shocked surprise in a hot mom's eyes as she realized her son had fully entered her.

"Be honest now, did penetrating like that turn you on, mommy?" Dr. Wood asked further. From the sounds Kelly was making and the way she was carrying on, Dr. Wood was sure that some real size had been exactly what the hot mom needed!

Kelly had never had a truly long and thick cock before. She felt crammed full of pulsating meat and recognized that she was reveling in being so full of cock and somehow having been able to take all of her son's cock inside her. She felt her cheeks burn as she replied, "Ahhh... honestly ... yesss! I can't believe how good his huge cock feels."

"I told you, hottie, you have a very capable vagina and it takes a man with some girth to make your pussy full. Remember, to truly feel fulfilled you need a big and thick cock," Dr. Wood said. She then added, "Now, when you are in the full-depth squat position, you are the one in control. I told you earlier that a full-depth squat would allow you unrestricted range of motion in all directions. You can move your body forwards and backwards to stimulate your clitoris and the rest of the outside of your vagina. You'll also find that by leaning forwards or backwards, you can change the angle of entry. All of that will help you to climax faster and stronger!"

Kelly softly moaned, turning her head to the side in embarrassment to avoid Dr. Wood's eyes. She could not believe what she was hearing from Dr. Wood. She just gave her advice about techniques for advance lovemaking and how to orgasm quickly. Then she remembered what Dr. Wood told her yesterday about having the orgasms when she and Jason had therapy. She remembered that it helped because she produced more of the fresh pussy juices in that manner.

Unknowingly, Kelly slowly started to move her hips forwards and backwards, pushing her pubic bone against Jason's, so her hyper-sensitive clitoris was rubbing his pelvis bone gently. She shuddered at the contact with his pubes; it felt so good. She kept moving forwards and back faster and pushing harder against him. His huge thick cock was reaching, touching and feeling parts of her that were virginal. He was so deep and Kelly was in heaven. For the first time, she felt the cock head brushed past her cervix with each movement. Shamelessly, she started rocking first back and forth, then from side to side, finally in circles.

Jason looked at his mom in disbelief, confusion and growing lust, as Kelly continued gyrating her hips around, making sure her clit was rubbing on his pelvis. Seeing his big cock finally lodged all the way inside his mom was just incredible! Her pussy was warm and tight, and it felt wonderful! Another huge orgasm was building within her; he could feel it. Then his mom began trembling and convulsing and her excited moans betrayed her third orgasm in less than ten minutes of the penetration getting started. Her warm pussy walls clenched around his hard, throbbing cock. It was almost too good to resist, so hot and tight, and Jason exploded, too.

At the same time an agreeable grin was forming on Dr. Wood 's face. She looked at Kelly with delight as Kelly lost control and began grinding down on Jason wildly. Up to now, Kelly had no idea that she could even react this way during sex. But now she did know. And Dr. Wood was very happy that Kelly could reach such intensity during sex. Dr. Wood will never forget the look of ecstasy and bliss on Kelly's face as she orgasmed. This time there was no regret, no resentment, and definitely no resistance.

Dr. Wood waited for a few minutes for Kelly to calm down. Obviously, Kelly was in no hurry to remove Jason 's huge cock. The strong, musky-smell of sex was emanating from Kelly! When he softened slightly, she rose up finally and slide on the bed next to Jason.

"Wow Kelly, it was great! But, I am afraid Jason didn't last long enough in this session, so you didn't lubricate your son's cock head sufficiently," Dr. Wood noticed.

"Yes, I know. I'm sorry... What should I do?" Kelly asked. Obviously she was worried about Jason's cock head.

"Although Jason didn't last very long this time, I'm sure he will get ready to penetrate you again quickly. So, it would be good if you allow him additional penetration instead of his regular masturbation," Dr. Wood suggested and added provocatively, "Of course, if you are capable during the day... I mean, if your pussy isn't sore."

"No Dr. Wood, my pussy's not sore at all. I think I can do it... for Jason," Kelly said hastily with a loving, longing look in her eyes. Until yesterday she had never been penetrated more than once in the same day. But now she would be penetrated more than two times a day!

"Great! Generally speaking, you don't have to limit yourself to just two penetrations during the day. The more his cock head has been dipped in your pussy juices, the better for him," Dr. Wood said and added with smile, "Besides, given your behavior so far, you'll most likely enjoy it!"

Kelly just nodded and blushed, realizing that she just got the permission from Dr. Wood to have 'penetrative sessions' with Jason as much as she wanted and could!

"I'll see you later," Dr. Wood added with smile and left the room, leaving them alone.

For a lot of the summer months Dr. Wood didn't have much work because most of her patients went on vacation. Having no reason to hang around the hospital, she decided to visit the Logan family again. It had been just one hour since she left them. When she entered the house, she started to call out to let Kelly and Jason know she had arrived, but she heard noises coming from Kelly's bedroom and remained quiet. Dr. Wood stole upstairs and stood for several seconds outside the door. There was a combination of moaning and long, deep sighs. She gently eased the bedroom door open slightly. Jason was on his back naked and Kelly was squatting on top of him, slowly sliding down on his long cock. When Kelly spotted Dr. Wood, she blushed and froze on the spot.

"I'm sorry, Dr. Wood," Kelly heavily breathed as she stopped her movement. Dr. Wood could see that more than half of Jason's huge cock had already entered his mother warm, wet and tight pussy tunnel.

"You started the session earlier..." Dr. Wood noticed softly.

"Yes... I wasn't sure when you were coming back. Jason was hard and I just wanted lubricate his cock head adequately as soon as possible," Kelly's voice quivered with eagerness, as she tried to justify herself. She was feeling pangs of guilt because the truth was something else. She was lost in loving the huge young cock which now seemed to rule her life. She wondered if Dr. Wood knew how she needed huge cock deep inside her.

"Oh... there is nothing wrong with it, mommy. I'm very pleased that you care about Jason's cock and you aren't afraid to show it. You proved that to me by doing what you do right now. So, go ahead. Take him fully!" Dr. Wood encouraged her.

Then with a look of almost serenity upon her face, Kelly focused back on her 'duty' and the pangs of guilt she had felt minutes before gradually subsided. She rose up a little and then guided her pussy lower, allowing Jason's cock to enter her pussy further, coating him with her juices at the same time. Jason watched his mom's wet pussy move up and down and he enjoyed the sight. Every time Kelly moved up and down, she could feel his fullness inside her making her vagina stretch to accommodate him again. Finally she stopped, his cock was full inside her, biting at her cervix!

"Ohh... ohh... I am so full! I can feel... ahhh... his cock against my cervix," Kelly panted as her pussy muscles was quivering around his cock even as she didn't move more. She so loved the new sensations of a his cock head massaging against her cervix. Then she started swiveling her hips around and the look on her face and her body language confirmed she enjoyed it! It was unbearable, feeling how hard and huge Jason was inside, and her body gripped him tightly, wet against his length. Whatever reluctance or embarrassment Kelly had felt previously, it was completely gone. Now she was completely into this. She was getting louder and louder with each passing moment, her eyes shone with pure lust and it was obvious she had stopped fighting and began to really enjoy the session.

"Ohh... ohh... I'm cumming!" Kelly admitted for the first time and her eyes roll up in her head as a huge pulsating orgasm roared through her body.

Dr. Wood waited for a few minutes while Kelly finally calmed down enough to hear her, "Kelly, you should be sliding up and down slowly on his cock, you will better lubricate his glans in that way."

Mostly unaware of what Dr. Wood was saying, Kelly replied, "Yes, Dr. Wood," and slowly rose up almost all the way off his cock. Just the underside of his glans came into view, enabling Dr. Wood to notice how wet Kelly was. She was almost gushing at this point and Jason's cock was fully covered in her wetness.

"Oh, you are doing great, mommy! His beautiful cock is literally glistening with your lubrication!" Dr. Wood praised her.

Kelly gasped and slowly thrust herself down again. Then she began to lift her body up and down on Jason's huge cock and Jason could see the pink membranes of mom's labia appearing and disappearing as she slid up and down on his long cock. Kelly leaned forward a bit, her hands grabbing Jason's chest for balance and immediately she felt that pleasurable jolt of electricity in her loins. His cock now rubbed against her G spot mercilessly!

"Aaaaah..." Kelly groaned, she couldn't hide her excitement. Obviously, she was on the edge on her second orgasm. Jason felt the muscles of her pussy spasm and contract around his cock. At that point a huge orgasm sent wave after wave of pure pleasure through her body. She groaned loudly again and began screaming. At the same time, Jason's cock exploded inside of her and she could feel the heat from his seed as it filled her too!

Moments passed without either moving or saying anything, while the last vestige of Kelly's orgasm faded from her stomach. She was feeling incredible pleasure from the extreme stretch that her vagina was undergoing and she resisted the urge to thank Jason. Dr. Wood just smiled at her with approval then she slowly left the house.

Dr. Wood waited patiently for the late afternoon session. She had deliberately left them alone all afternoon to make them feel free.

"Tell me, how did you two spend last five hours alone?" Dr. Wood wanted to know what happened while she was absent.

Kelly paused while she considered how to articulate her statement.

"Err... Jason had erections a few times... more precisely, three times," Kelly began, uncertainty in her voice.

"Three times! Your son is really potent and full of sexual energy. He must be extremely horny and aroused by your presence. Or, I better say, by your hot body," Dr. Wood noticed with smile and a moment later asked, "Did you masturbate him or...?"

"Err... I figured..." Kelly was confused by Dr. Wood's words. "I figured... it was better for his health to allow him to penetrate me, better than just masturbate him or give him oral," Kelly finally answered shyly. Then she added, obviously trying to justify herself, "You said this morning that I don't have to limit myself to just two penetrations during the day."

"Of course, mommy. I'm glad to hear that you allowed him to immerse his cock in your healing pussy juices extra time," Dr. Wood praised her.

"And... I tried to postpone his orgasm and hold his cock head in my pussy more than just 15 minutes," Kelly continued and blushed, aware that Dr. Wood knew what the real reason was. The days past from their first encounter and Dr. Wood knew it was because of her natural extreme sexual desire, and doubt. Turning to look down at Kelly, she saw her in a whole new light. She gazed into Kelly's eyes and saw the awakened lust, love, and passion that were harbored there for her son and his huge cock. Kelly was turned on, her large chest heaving with her quickened breathing and it was more than obvious that she wanted so badly to please herself.

"Great! When I recommended 15 minutes of penetration, I thought minimum 15 minutes. The longer the better!" Dr. Wood agreed. Not wanting to further upset her, Dr. Wood added, "Oh mommy, your big boy is so hard, I think he's barely waiting to immerse his huge cock in your warm wet pussy. Are you ready, mommy?"

"Ahh... yes... I am," Kelly answered, trying to hide her excitement, as she felt her heart race in her chest. She readily went to the bedroom, but Dr. Wood actually had what proved to be a much better idea.

"Why don't you just do it here, on the floor?" Dr. Wood asked, smirking naughtily.

At first Kelly was mildly shocked at the suggestion, yet strangely excited too, "What! On the carpet? We can't do that!"

"Why not? Relax! No one except me is going to notice you doing it. And it'll save you the time of going to your bedroom. Also, it'll be kind of fun anyway, don't you think?" Dr. Wood giggled at the naughtiness of the idea nevertheless.

"Yes...," Kelly responded obediently by moaning softly and rubbing her warm thighs unconsciously.

Obviously, Kelly was a bit confused, so Dr. Wood did not waste time teasing her more. Instead she ordered Jason, "Lay here, mom's big boy."

Jason readily laid down on the floor, and Kelly immediately stood over him, a foot on each side of his hips. Obviously, she was not confused now. Then she slowly lowered herself down on his huge cock. She split apart as he entered her and then she stopped. Even after two days of frequent intercourse with him, she still felt his huge cock opening her and her pussy stretching to accommodate it.

"Oh that's so nice, mom," Jason urged as Kelly began grinding her hips back and forth and her pussy muscles rippled impossibly around his cock.

Kelly just moaned and, looking Jason in the eyes, started to move up and down on him using her powerful leg muscles to do so. She knew how Jason liked to watch his long cock slide in and out of her hot pussy. However, his big cock head was finding her G spot with every plunge, so after a just few minutes of penetration Kelly had her first orgasm, followed by a long and muffled moan of pleasure.

"Mmmm... well done, mommy," Dr. Wood praised her and added looking at Jason, "Your mom came quickly, coating your cock with her healing cum. This is very important to heal your cock head and you have to appreciate that."

"Yes, of course," Jason answered frankly.

During that time Kelly was breathing heavily and her body was pulsing hard. Finally she calmed down. But she didn't keep moving on his cock.

"Is your pussy sore, mommy? It looks kind of red and swollen," Dr. Wood asked worried.

"No, no," Kelly replied quickly. "My pussy feels fine. Just my leg muscles... are strained."

"Ohhh... this is expected... all day you are relentlessly pumping his cock in the squatting position. This position really works the legs and can get tiring for a woman. We need to find a better position for you. Get down so that your knees are on the bed. Also, you can put your hands on his chest, shoulders or the bed to steady yourself or you can just put them on your thighs," Dr. Wood suggested, apparently pleased with Kelly's response. She was afraid that the problem was her pussy soreness.

Kelly obediently did as she asked. She straddled him with her legs either side of his waist so that her knees were on the bed. Then she rested her hands on his chest, steadying herself.

"Now it's better ... and more comfortable," she confirmed, adjusting her position. However, his cock pulled out a bit as she kneeled and leaned forward. He was about half way in and Kelly moaned, frustrated as she felt emptiness in her pussy and somewhat disappointed that the fucking had stopped.

It got even worse when Dr. Wood instructed, "Get up a little, honey!" Kelly moved up till only his huge cock head was in her hot pussy. She was breathing heavily now, and she was very confused and frustrated.

Dr. Wood waited a moment or two and then continued on, "Mommy, his cock head is immersed in your wet pussy... that's fine... but... he will not be able to ejaculate in this way. I mean, there is no way to stimulate his cock enough to cause his orgasm."

Dr. Wood paused and waited for some reaction from Kelly. This time Kelly's mood seemed different, she still seemed a bit frustrated, but her body, already highly aroused, reacted to the opportunity Dr. Wood offered. Looking into Dr. Wood 's eyes, Kelly arched her back and started slowly moving her pelvis forward and backwards, moaning and nodding her head in agreement.

"Ahhh... yes. What should I do?" Kelly asked, although she did not know exactly Dr. Wood was offering.

"Oh...well, can I suggest that you allow him, instead of you, err... to raise his hips and pump his cock into your pussy? So you can rest your sore muscles," Dr. Wood said lightly, impatiently expecting Kelly's reaction. She knew it would mean Kelly allowing him to fuck her!

Fear, confusion, panic, lust, excitement... all those emotions and more overcame Kelly. For a few seconds she was frozen in place.

"Instead of me? Yes... It's true... in this very comfortable position I can rest my sore muscles," Kelly confessed. "Well, if you think it will help Jason to cum..." She was entirely unaware of what she had just said. But, she wanted this big, thick cock! Oh, how she wanted that big cock now! It was a horrible thing to admit to herself, but it was true!

Jason couldn't believe it. His mom allowed him to fuck her! He looked at Dr. Wood and she just nodded with smile. His heart was pounding in his throat as he began to pump his cock into his mom's pussy slowly from underneath her. He could feel the sexual tension in his mom's body relax just a bit as she started to moan throatily from pleasure. His assuredness was growing fast and he started to fuck her harder and faster. Kelly growled, her hands grasping his shoulders to hold herself in place. She loved this feeling, the frictional warmth radiating through her hips and lower belly. Each time his cock pulled out of her it was glistening with her juices, she was sopping wet. Having already come five times that day, Jason was able to keep going without fear that the fucking would end too quickly. So he took the initiative.

He ran his hands over her soft naked body, up her long silky smooth legs and over her thighs, placing finally them on her round bottom, giving it a good massage and squeezing gently whenever he found a particularly sensitive spot. He loved the firmness of his mom's shapely ass cheeks as he tightened them. For the first time Kelly felt Jason's hands on her ass, touching her in a sexual way. She looked at him with blurry eyes but didn't protest, she just moaned uncontrollably. Her body was writhing, unable to handle the sensations and the intense pleasure shooting through her pussy. So Jason continued to hold her curvy buttocks apart as he fucked her hard.

The sight of his cock pistoning in and out of the mom's hot pussy was mesmerizing for Dr. Wood. "Just keep it up, Jason! You're doing so good and I'm sure you enjoy it as much as your mommy does," Dr. Wood praised him, but she didn't miss the opportunity to make known how Kelly enjoyed the feeling of him entering her.

"Mommy, you can also find that by leaning forwards or backwards, you can change the angle of entry," Dr. Wood suggested to her.

Kelly nodded, leaned forwards and moaned with pleasure. In new position, she could feel the soft skin of her belly pressed against his stomach and her huge tits lowered until they were barely touched his chest. And also her clit was now completely exposed and she could feel his pubic bone rubbing against her clit with every movement and every stroke. She tossed her head back and forth, her pussy was throbbing and her belly was tight as her pussy prepared to explode.

As her asshole begin to throb violently, puckering in and out, Dr. Wood asked expectantly, "Are you going to come for your son again, mommy?"

"Ah ah ... yes..." Kelly was barely able to sigh out. She was losing her grip on reality. Her nipples grew stiff and tingly, poking into her son's chest.

Her pussy started spasming, uncontrollably contracting around the steely length of her son's cock. But Jason didn't stop, his monstrous organ continued to ram into her willing pussy, slamming faster into her with his long thick cock and pulling her wet pussy lips apart. The strokes were incredibly deep and satisfying and Kelly felt herself getting ready to cum again. Shamelessly the horny mother gasped, "Ahhh... I'm gonna cum... again! Ahhh... what a big, beautiful cock!"

"Yes, do it mommy, cum hard! Cum for your son, he loves when you cum on his huge cock," Dr. Wood encouraged her.

Over the next ten minutes, Kelly seemed to be in constant climax, huge orgasms rolling and rolling, crashing and battering through her. Evidently she came countless times. Finally, Jason felt his cum building in him, from his toes to the top of his head.

"Ah ahh... I'm cumming,... I'm going to explode!" Jason announced as he looked up at the Dr. Wood, still trying to hold back his cum.

"It's going to be okay... Just let it happen," Dr. Wood instructed. The incredible energy flowing between them was so evident. She knew from his body and facial expressions that he had reached the point of no return.

Jason began to forcefully thrust his hips forward, then he got into his short strokes. He pumped Kelly's pussy with fast thrusts, searching for the friction to give him the relief that he so desperately needed. Dr. Wood knew he needed just a last push to set him over the edge, so she continued to talk pure filth to him, "Fuck mommy's pussy harder, honey. Fill your mommy with all that hot cum of yours. She wants that! And satisfy her like she's never been satisfied before!"

He began to grunt loudly and his cock spasmed as the wet, sticky cum blasted out in long ropes into Kelly's cervix. His spasms lasted for a good 30 seconds, coating Kelly's vaginal walls and flooding her with his huge load. The warm spot inside her grew as he emptied himself into her, and that was all Kelly needed to start her final climax. Her body shook with pleasure as her sensitive pussy started the long slide down to orgasmic pleasure, sucking and squeezing as if trying to get every drop of sperm from him.

The sensations lasted for a few minutes as they breathed hard and fast, joined together by cock and pussy. Now Kelly was lying completely across him until Jason slowly pulled his wet cock out of Kelly's stretched pussy hole. Kelly gave a little gasp of disappointment and collapsed on the floor next to Jason. She sat there, legs apart, sweaty and spent. Her pussy felt so empty and open and the juices of their orgasms began to ooze out, drenching the carpet. Dr. Wood bent down between Kelly's legs and took a closer look, "Oh Jason, it looks like you needed that! What a nice big sticky load! Did you enjoy it? "

"Ah, yes. Mom was so amazing and made me feel so good about everything. She was so tight down below... The tightness and the feel of her warm wet pussy was so fantastic!"Jason blurted out. He didn't hide his excitement.

"What about you? Did you enjoy it, mommy?" Dr. Wood asked in a teasing voice.

"Ahhh... yes!" Kelly whispered. She lay there thinking about what had just happened.

"Really?" Dr. Wood pretended not to believe that it was.

"Yesss... It was great! I have never been fucked like that before!" Kelly burned with shame when she realized what she said.

"Don't be embarrassed, dear. Jason certainly showed lots of stamina this time, so I trust you!" Dr. Wood said with smile. Her words let Kelly relax a bit knowing her reactions were normal to Dr. Wood.

"You should be grateful, " Dr. Wood added.

"Ahhh... thank you, Jason," Kelly sputtered out, melting, fuzzy-headed.

Then Dr. Wood stood up and said, "Jason, I am pleasantly surprised that your mom has so much untapped sexual potential. This, of course, gives us plenty of opportunities to explore and experiment sexually! That's very important for your treatment."

Kelly found herself deeply ashamed, blushing red, trying to work out what Dr. Wood said. However, no matter how hard she wanted it, Dr. Wood gave no further explanation.

"See you soon, in the evening session... errr... for about two hours. Have a rest, you need it!" Dr. Wood added and left.​
