Incest/Taboo Mom's Fertility Clinic

Leo

It was a week ago that I'd given the first container of cum to Mom. She hadn't made any faces, and neither had I. It hadn't felt as awkward as I thought it would. I'd just carried on with my day as usual.

Today, I had a checkup with my aunt. I was still flabbergasted from the last scene when she'd actually gone down on me. It was my greatest sexual experience to this day, and she was right, I wasn't so keen on chasing virgins any longer.

I was a bit worried though since my shots had been nowhere near as powerful as when my aunt had blown me. Yesterday, I'd given a container to Mom, and there wasn't as much in it, but I hoped it would yield some results.

Mom would be home any minute. She'd wanted to see me before I headed to Isabella. I had a feeling she wanted to share some good news. It was typical of her whenever she would act cryptically.

Mom opened the door. She was dressed in a tight skirt, hugging her forbidden curves like it was made for her. She wore a top and wore her hair in loose curls. She smiled, opened her arms and pulled me in a bear hug. I embraced her back, wrapping my arms around her and pulling her warm flesh to mine. I was aware of her breath against my neck, her boobs mashed against my chest and her floral perfume that made her smell like a rose.

I melted in her arms and didn't question why she suddenly hugged me like that. It just felt so good at the moment. She pressed her soft lips to my cheek but dangerously close to my lips. "A client called back," she said, her eyes welling with happy tears. "She'd tried every fertility method known to man. I encouraged her to try out your semen which you'd given me a week ago... Now she has a baby growing in her belly."

I was struck by an empowering feeling. I'd bred someone and spread my blood and genes. It felt like a major accomplishment. "Nothing else besides my seed worked?" I asked as if it were too good to be true.

"Nope," she said, shaking her head. "She has some friends who've struggled with fertility too, and they have signed up as well. You're saving my business."

"You're welcome," I said and it made me happy that I'd been there for her.

She opened her arms again. "Another hug?"

I couldn't resist her flesh and let her fall into my arms. I let my hands roam around her back, reaching the curves of her ass. I had to stop myself, hoping I wasn't taking it too far, but the way we'd cooperated made me feel closer to her. Our hug might have seemed a bit too intimate than what a son should hug his mother.

We broke it, and we looked into each other's eyes. "I'm grateful to have you," she said, drying her eyes. She was so gorgeous it was unbelievable. Her skin was baby-smooth and wrinkle-free, and her breasts sat high on her chest and would make a young girl green with envy. I wanted to reach them similarly to how her sister had touched them. I also wanted to peel off her clothes and touch her privates.

I shook my head when I realized I was popping wood in front of her. She just placed her hand on my shoulder and looked up to my eyes. "It's okay. Will you see my sister?"

"Yeah... We'll do a checkup."

"I'll have dinner ready when you're back," she said. She leaned forward and pressed her smooth lips to my cheek again, leaving a damp patch of her forbidden skin behind.

I arrived at Isabella's office. She beamed upon seeing me and pulled me in a hug before I even had a chance to check her out. She was dressed in a similar outfit as last time: sexy stockings, a mini skirt and a blouse sitting a bit too tight on her. "Mom already texted me the good news," she said, breaking the hug to look up at me.

"She told me too," I said. "But I have to tell you something though."

"Let's go to my office." She whisked me inside, and it felt great to be back here again. She closed the door after her, and we had a seat. "So, what's on your heart?"

I fished out the container of cum and handed it to her. "I have a gut feeling that my cum isn't that strong when I masturbate by myself. I still shoot a lot, but when I was with you or when I watched you and Mom, there was a lot more, and the cum was thicker too."

"That sounds odd," she said and opened the container. She took a swab and dipped it in the pearly pool, examining my pearly buttermilk. "Hmm, you're right. It isn't as thick as when I went down on you."

"When Mom told me that my cum had successfully made one of her clients pregnant, she was so happy, and it made me so glad for her. I just want to make sure nothing will happen."

"You're so mature for your age," she said, taking her eyes off my cum only to look at me with pride. "How much time do you have?"

"I'll stay here for as long as it takes," I said.

"I'll compare this with the first sample you gave me. Give me ten minutes," she said. She went into the corner by herself and started examining my seed. I leaned back in the chair and waited patiently. I, for some reason, became turned on while waiting. I had a big sex drive, but I clearly remembered what took place here during my last visit. I closed my eyes and fantasized about having her lips wrapped around my cock. It wasn't only the fact that my seed would be used to breed other women, but that she was my aunt, and we shouldn't be messing around with each other.

"Okay," she said, bursting my dream bubble. I glanced down at my hard bulge, which was clearly visible. I tried to pull my shirt down to cover it, but Isabella just chuckled. "Don't worry about it."

She had a point especially since she'd already seen it. I let go of my shirt. "What have you found?"

"There's less sperm per milliliter semen in this container compared to your first visit, but it's still a lot, and it certainly will help a struggling woman to become pregnant."

"I want to make sure it will be as strong as possible," I said. "I want to make sure my mother gets the best product."

"We already have some clues," she said and took off her glasses. She aimed her beautiful, blue eyes at me. Her full, red lips curved in a smile. "When you fired hard, made flowers grow to six inches and blasted me off the bed, you did something which you shouldn't, quote-unquote, be doing."

"Do you think that contributes to how strong my seed is?" I asked.

"I'm almost certain of it," she said. She tugged at her blouse. "It's so hot in here." She popped the buttons free, revealing a top with a plunging V-neck that left the upper parts of her creamy, delicious boobs fully exposed. She rose and was about to hang the blouse on the knob but accidentally dropped it. She picked it up, and while being bent at the waist, she flashed me her marvelous, heart-shaped ass. My cock hardened to a point of no return, and if there wasn't a surprise waiting for me at the end of this checkup, I would run home to my bedroom. "What about when you're having sex with your girlfriends?"

"The climaxes were certainly stronger than just masturbating but paled in comparison to what I experienced with you."

"I'm almost certain that the amount of arousal plays a key role," she said. "We can... perhaps try it out now for instance."

That was the comment that I'd been waiting for. "Will you... go down on me again?"

She aimed her eyes at me and broke out in a grin. "I think to fully test this out--You should go inside me."

I stiffened, and I experienced a similar reaction to when she'd suggested blowing me last week. "Sex?" I said to make sure we were on the same page and she wasn't cryptically trying to say something else.

She nodded broadly, her eyes sparkling with excitement.

"What if I make you pregnant?"

"I'm on the pill," she said.

"I'm not so sure about this," I said, but my cock twitched and told a different story.

"Why is your cock hard then?" she said. She jumped to her feet and strode toward me, making her hips swat on her way. She took a seat right next to me, inching her magical hips against mine and placing her hand right on top of my throbbing cock. I picked up the scent of her nectar. She must be drenched since it smelled sweeter and stronger than a flower field. "Don't you want to help your mom out?"

Her warm breath and sweet voice were so enticing. She kept stroking my length. Only my garment separated her flesh from mine. "I sure do."

"Let's say we're doing this for her."

"So, if it turns out my seed becomes stronger when I'm doing something I shouldn't be doing... then what?"

She sank her teeth into her bottom lip and moved closer to my ear. "Lots of taboo sex."

I was surprised my cock didn't burst through the zipper. "A blow job is one thing but sex is another."

"Your eyes don't lie," she said and ran her hand back and forth over my length. "I know you want this equally as much as I do."

"Mom is right... You can be seductive at times."

"I love to live," she said and slipped her soft hand under my pants and reached my thickening cock. I melted upon the touch as her soft fingers curled around my girth. Her smile widened as she ran her hand up and down the length. "I know you do too." She was about to press her lips to my cheek, but I turned at the last second and made our lips touch for the first time in our lives. I caught her by surprise, but I didn't want to suppress this any longer, especially when I remembered how good the blowjob had felt.

I cupped her neck to deepen the kiss. I slid my tongue into her forbidden mouth, and she opened without hesitation, welcoming me into her warm, wet mouth. I melted a little inside her. Our tongues hugged and swirled together. We exchanged our saliva, and the guilty pleasure was about to derail me. It felt so good, and the euphoria triumphed over the nagging voice in the back of my mind that screamed this was sick. It wasn't. It felt too good to be sick.

We broke the kiss, and a string of saliva clung from lip to lip. She bit her bottom lip and eyed me with lust and hunger. "You're a damn good kisser," she said.

"I'm damn good at fucking too."

"Show me," she said.

We rose from our seats and headed inside the masturbation room. She quickly took off her top and tossed it aside. I took off my shirt and tossed it onto her top. I grinned at her chest and wanted to tear her bra to pieces. We gravitated toward each other. I pushed her hair behind her ears, exposing her face which reminded me so much of my mother. I reached behind her back and easily unhooked her bra. I freed her delicious boobs from their confines and greedily squeezed them.

"They aren't bad?" she asked, and I remembered how she'd been envious of my mom's tits.

"They're perfect," I said. While I was fondling them, she skillfully pulled the belt off the loops. Suddenly, my pants fell to my ankles and only my underwear was left. She immediately curled her fingers around the waistband and pulled them down, her breath warm and husky against my chest.

I pulled down her skirt and touched her panties. She'd already soaked through them and the center was all warm and sticky, preparing to accommodate my thick girth. "Just pull them off," she desperately said, and I did as she wished. I pulled them off and let them fall to her ankles.

I watched her ass in the mirror. I towered over her and was half a foot taller. It was the first time I'd ever seen my aunt nude, and I wasn't disappointed. My cock was squeezed between my waist and hers, which helped rub the head and shaft. I slapped my hands on both her ass cheeks, and the loud smack was incredibly satisfying. "Admit it you've dreamed about this," Isabella said, looking up to me.

"I have," I said. "And nothing will stop me from making it come true now." I grabbed her and lifted her onto the bed. I jumped on top too and spread her legs and exposed her pink, beautiful pussy. I ran my thumb over her wet heat, smearing her honey from the bottom to the top. I then eyed the center, which kept dripping.

I leaned nearer, and the honeyed scent pulled me closer to her. She was the first milf I'd ever been with, and I knew she wouldn't be the last. I pressed my tongue flat against her pussy and absorbed her sweet flavors. Every single virgin I'd been with tasted slightly sour, but my aunt was perfectly ripe.

I licked her in slow, sensual strokes. I smacked my lips and kissed her several times. She squeezed me with her legs, whimpering in pleasure as I kept tasting and licking her. "Oh, Leo," she moaned. "You're the best nephew in the world."

I was grateful to have such a dirty aunt like her. I latched my mouth onto her slit and slid my tongue as far into her as I could. I managed to send another shiver down her spine as she moaned out my name. I came off with a smack and sat back up. I crawled closer to her, watching her beautiful, forbidden pussy, wondering whether Mom's was as beautiful as hers.

I lined up my throbbing erection with her pussy. A part of me couldn't stop thinking of how surreal this was. The other just wanted to plunge my cock into her depths in the pursuit of that taboo friction. "What's taking so long?" she asked impatiently. "Just stick it in me."

I pushed the head in first, parting her pussy lips as inch after inch disappeared inside her heat. A long, slow shiver ran down my spine, and it lasted till I'd bottomed out in her hole. I'd never felt such a pleasant shiver in my life. It was just the first stroke, and I couldn't help but ask myself how it would feel when I would empty myself inside her.

I pulled back, and my cock came out glistening wet. I pushed it back in again, and my eyes flitted to hers. She breathed heavily. "Oh, you're so thick," she said with her eyes closed.

"You're taking it well though," I said and pulled back out and pushed it back in.

"What about those teens, can't they take it in?" she asked with a chuckle.

I grabbed her hips and increased the fucks. "Hardly," I said, and she infected me with laughter.

"How does it feel to fuck your aunt?" she asked as she started moaning for every hip-thrust.

"Unbelievably good," I admitted. It was incredibly thrilling.

"How about the fact we do this raw?" she asked.

"It feels even better," I said as our flesh started slapping and my lust grew even stronger.

"I want your cum so badly," she said, squeezing her boobs as I kept pumping her harder. The second she let go of her breasts, they jiggled and bounced all over her chest.

"I want to give it to you equally as badly," I promised her as I wasn't far from the peak. The orgasm was slowly building, and it was a slow and teasing journey to the top. The taboo thrill helped hold me back, but the fact that the orgasm was delayed just made this feel so much better.

I pulled out my dripping-wet cock, and she gave me a worried look. "On the side," I told her. We lay on the side, and she backed her warm, soft ass against me. I grabbed my cock, aimed the head at her honeyed hole and thrust right into her depths with a mighty groan. "There we go."

I lifted her leg, making me reach her pink entrance a bit deeper. I reached her tit, squeezing her soft boob, making her whimper in pleasure. "Oh, you know what you're doing."

I moved my lips closer to her neck, delivering several kisses on her sweet, tempting flesh. I moved my fingers closer to her pussy, fingering her clit a little which made her arch her back and back her ass against my crotch. "Ah, Leo," she shouted my name.

I grunted for every thrust, and the sensation turned more and more powerful. In the end, I let out a savage cry as I felt an orgasm unlike any other. My testicles detonated, and within the blink of an eye, I flooded and drowned her womb. By sheer force, my cock was pushed out like a hose, and I shot two, thick cables of cum on both her breasts which splashed all over her.

She glanced down and got a load right on her face, and the droplets spilled all over her hair. I then sprayed the rest over her waist, coating her in my thick, pearly cum.

I was out of breath and completely flabbergasted. I arched an eyebrow and looked at the mess for a second before the second wave of the pleasurable orgasm hit me. I slumped back, holding on to her warm flesh. I didn't want this to end. It paled in comparison to having sex with random girls from the gym. "Isabella," I said after a couple of minutes.

"Uh-huh," she said, turning her beautiful head to me which was currently covered in cum.

"Sorry for the mess," I said, making us both laugh.

"No need to apologize," she said and scooped some from her cheek and put it in her mouth. "I love cum."

"This was intense," I said.

"I told you... now if this load isn't potent then I don't know what is."

"Me neither," I said.

"So, you won't work lonely then," she said with a wink.

"I'm looking forward to this," I said. I wanted to squeeze her boobs and ravish her flesh again, but she was covered in a ridiculous amount of semen. I couldn't even lift her leg without getting it all over my hand. I slowly pulled out my softening cock, dragging out a river of cum with me. I watched the creampie in awe.

"Gosh, that's so hot," she said and parted her pussy lips. "Can you do me a favor?"

"Sure," I said.

"Fetch me one of those containers."

I swung my feet off the bed and grabbed her. She positioned it right under her slit, and my cum just ran right into it, slowly filling it. She moved the cup aside, but my seed continuously ran out from her in thick rivulets and continued down the insides of her thighs. She aimed her eyes at me. "I think you'll make your mom wealthy," she said with a filthy grin.

I couldn't help but laugh. "I hope so."​
