Incest/Taboo Empty Nest

I took a step closer to him. "I don't want to interfere with your relationship, Ben. I don't want to make you do anything you're not comfortable with. I just want you to know... if you want her... I'm okay with sharing you."

Ben's eyes went wide as saucers. Out in the hallway, the sound of running water stopped.

"The shower in my bathroom is better," I reminded Ben, and turned to leave. Kayla, wrapped in a towel, was at the door.

"Thanks again for your help with the crib, Kayla," I smiled sweetly. "If you've got any laundry just bring it to my room."

"Sure, Mrs. Marshall," she said, unable to help looking down at my chest as I waddled past her.

I returned to my room and pretended to sort the laundry. I thought Ben wouldn't go for my invitation. But a few minutes later he silently passed me and started the shower in the master bathroom.

I waited a few more moments, humming, busying myself with the laundry. I smiled at Kayla when she left Ben's room and went to the other bathroom to do her hair and makeup. I heard the hair dryer start. I closed my bedroom door.

Ben was in my shower; I could see his form through the frosted glass door. My heart raced as I watched him wash himself.

I slid the shower door back and smiled at my son. "Hey, sweetie," I whispered.

He looked back at me, nervous, excited. I needed a shower too, but I wasn't about to squeeze in there with him. Instead, I took a step back, took a breath, and peeled off my t-shirt.

Under the sound of the water, I heard Ben whimper. My breasts were larger than they'd ever been, hanging low on my stomach. As they prepared to nurse my new son, veins stood out under my skin. My areolae were dark, the size of saucers. I watched Ben look at them. I watched between his legs as his penis hardened. His skin glistened under the falling water.

I lifted one breast, making a show of how heavy it was. Then I ran my thumb over my already stiff nipple. Ben was fully hard in a matter of moments.

I mimed a jerk-off motion to him, and he grasped his penis. His face contorted as he watched me put on a show for him. I played with both my breasts, lifting and bouncing them, then releasing them and letting them sway as I shimmied back and forth. I bent over and let them hang.

The bathroom got steamy, reminding me of our encounter in the car the last time Ben was home. As he stared at my breasts I stared at his penis, watching him play with it, seeing how aroused I could still get him. My insecurities were evaporating. In my belly, my new son kicked and squirmed, sensing my racing heart. I reminded myself that I was carrying Ben's child, and I got wetter than I already was.

I knew what my son was waiting for, and we didn't have much time. I lifted one breast with both hands and massaged it, warming it up. Getting things flowing. Then I moved my attention to my nipple.

It took a couple tries, but soon a dribble of thin, nearly clear fluid leaked from my breast, down onto my big ripe stomach. Not real milk yet, but close enough. Ben shivered, and I thought he'd finish right there. He was jerking himself furiously, red in the face, panting.

I met his eyes and smiled sweetly. Then I lifted my breast, oh so slowly, to show him a new thing I'd discovered and thought he might like. They were big enough now that I could touch my own nipple with my tongue. He saw what was coming and let out a little moan as I extended my tongue, teasingly slowly, touched it to my sensitive brown nipple...

And then I gave him a little wink and left the bathroom. As I closed the door I swore I could hear a whimper of despair. Poor boy, I'd gotten him all worked up. I went back to Mom mode, throwing on a fresh t-shirt and sorting the laundry. When I opened my bedroom door Kayla was still drying her hair.

The game was on. That evening I took Ben and Kayla out to dinner. I picked the same dress I'd worn to Ben's goodbye dinner, back in my second trimester, when it was already a little tight and showed too much of my chest.

I thought I'd shock Ben, but when I came downstairs in it Kayla was also showing off a lot. Her pale pink dress clung to her hips and her narrow waist, showing her to be more shapely than I'd realized. Her breasts, while nowhere near the size of mine, were pushed up to create young, perky cleavage. I figured Ben had encouraged her to dress like that. He sat there in the living room, his hand on her inner thigh, smirking at me.

The two of them sat in the backseat together on the way to dinner, holding each other. I tried to keep up a conversation, but it wasn't happening tonight. Ben kept kissing Kayla and soon they were lost in their own little world, making out while I felt like an ornery taxi driver. I wanted to kick them out.

Kayla's lipstick was smeared by the time we arrived at the restaurant. On the way inside, Ben led her with a hand on her lower back, like a true gentleman, while I waddled behind. He made sure I saw him squeeze her butt.

I'd made the mistake of not specifying a table when I made the reservation, so Ben and Kayla sat on one side of the booth hip to hip while I struggled to squeeze my swollen pregnant body into the other side. Next to the cute, flirty young couple, I looked old and fat and sad. The conversation picked back up, mostly because Kayla was still making an effort to be nice, but I writhed uncomfortably on the bench seat as they touched each other and giggled through the meal.

Twice I had to laboriously remove myself from the booth to shuffle to the bathroom, and twice I returned to find my son's tongue down his girlfriend's throat. The meek, sweet, shy Ben I'd first welcomed into my bed in February was gone. Kayla would blush and apologize when I interrupted them; Ben would just smirk.

The drive home was even worse. The makeout session in the backseat got so hot and heavy that Kayla asked Ben to stop, embarrassed but clearly having fun. She glanced at me when she said he should cool it, and I knew she was taking pity on me. Didn't want to make out in front of Ben's old, lonely, pregnant mom. A few moments later Ben met my eye in the rearview mirror. Winked. My teasing had been returned and then some.

At home I desperately needed to get out of my clothes, and Ben and Kayla had similar thoughts. Ben said he'd meet me downstairs to watch some TV once they'd changed, but it seemed to take a while for them to get new clothes on. They'd only been in Ben's room a few minutes before I could hear giggling from down the hall.

I finished pulling on my robe, the same robe I'd worn the night Ben had first undressed me. I listened: more giggles, then a moan. Then muffled voices. I stepped into the hallway, my weight making the floorboards creak. Slowly I padded past Ben's room, and then I realized: his door was open. Just a crack.

I couldn't help glancing in. I was able to see my son, standing by the foot of his bed, naked except for his bulging underwear. Kayla was spread nude in front of him. She was turned away from me, so I couldn't see her face, but I could see just about everything else.

She was as pretty as I'd feared. Soft, flawless skin. A nearly flat stomach. Breasts that were high and firm and symmetrical even when she was laying down, her little pink nipples right in the middle rather than pointing down at the ground like mine. Her pussy was neatly tucked away, with the tiniest tuft of fur on top.

"Ben, come on. She'll hear us."

"She went downstairs. You heard it."

It had been ages since I'd seen another woman nude, even just a glimpse like this. I was struck by how different her body really was from my own. We were both beautiful, I thought, holding my stomach through the soft robe that barely fit around my middle anymore. Just in different ways. We could each give Ben something different. It didn't mean he didn't love me.

Ben was admiring the girl spread out before him, and then he looked up. Met my eye through the gap in the door. No wink, but there was a flash of knowing between us. And then he knelt by the foot of the bed.

I felt glued to the spot, weighed down by a body twice the size of Kayla's, wanting to watch. But I knew how horrible it would be to be caught. Ben could see me, and if Kayla threw her head back at the right moment, she'd see me too. So I tore myself away just as she scooted down the sheets and spread her legs.

Luckily, they couldn't hear my footsteps on the stairs over her moans. I could hear them clear as day even when I got downstairs and turned the TV on. Last night I'd been disappointed in my son, having heard him climax but not his partner. Be careful what you wish for, I told myself.

Ben and I had done lots of things together, but he'd never used his mouth on me. He had to know it would drive me nuts, sitting down here and thinking about his head between that girl's legs. Even though I'd told him early in our relationship that oral sex felt a little too intimate for us, I'd broken that rule by sucking him off.

I sat on the couch while the TV droned and slipped a hand into my robe, caressing my own sensitive breast until my whole body was warm and tingly. The moans upstairs turned to shrieks. Ben was doing something right. I felt a strange pride, even as jealousy flowed through me.

I thought about sliding a hand down between my legs, but worried when the kids came downstairs they'd be able to smell the sex on me just as badly as I'd smell it on them. I held myself back, sticking to teasing my nipples. Ben would give me my next orgasm, I thought to myself as Kayla reached her own climax upstairs. I just had to find a way to make it happen.

The next morning, as we wrapped up breakfast, I turned to Kayla. "Kayla, I need to borrow Ben for a little while today. Is that alright?"

"Sure," she said. "What for?" Ben shot me a look. This was the first he was hearing of this.

"I need to get a changing table at Target," I told her. "And I can't lift it myself."

"I could come with you! Help pick out more baby stuff!"

I shook my head. "I don't need to bore you with that. I booked you an appointment for a mani-pedi. My treat."

"Really? You're the best, Mrs. Marshall."

I didn't show off too much skin today, opting for a simple, flowy maternity dress with a cardigan for the chill. Kayla had a cute autumn getup but wasn't showing her tits off like the night before. She and Ben sat in the backseat together, his hand on her knee, but there was no fevered makeout session today. I hadn't flashed Ben this morning or teased him with my milk.

Were we back to being a normal family? I didn't think so. I'd thought of nothing but sex all morning. And Ben kept throwing little glances at me. He knew I was up to something.

We dropped Kayla off at the salon and Ben kissed her goodbye. I invited him to the front seat. For a while, we drove in silence.

"So where are we going, Mom?"

"I told you, to Target. I need that changing table."

"Okay," he smiled. "But what else? I know you're up to something."

I drove quickly, weaving through traffic. Kayla's appointment would only last an hour. "What would I be up to, Ben?"

He was confused, and I enjoyed that. It was fun to play with him. "Aren't we going to... you know..."

"I don't know, baby. What do you think we're going to do?"

"Have sex?" he blurted. I smiled.

"Is that what you want?" I asked as I pulled in to the Target parking lot. "It seems like you're having plenty of fun with Kayla."

"You want do, don't you?" Ben said, red in the face. "You've been messing with me all weekend!"

I concentrated on finding a place to park. Luckily there were a couple expectant-mother spots right up front. I pulled in and looked at Ben.

"I want to hear you say you want it," I told him.

"Mom, you know I love you. You know I'm attracted to you." Ben was sputtering, used to me being more gentle with him. I was enjoying my role.

"That isn't what I asked, sweetie," I told him. "I want to be sure I'm not pushing you into anything you don't want. I don't want to interfere with your relationship. So, do you want it, or are we just playing around?"

Ben smiled. "I want it, Mom."

"What do you want?"

"I want to have sex with you."

A pleasant little shiver ran through my hormonal body. "Even though you have a cute young girlfriend?"

"Yes, Mom."

"Even though I'm big and fat and pregnant?"

"Yes, Mom."

"Glad we settled that," I said, turning off the engine. "I've really got to pee, as always. Do you know where the family bathroom is in here?"

"Yeah."

"Good. That's where I'm headed. Wait five minutes once I'm in, then knock twice."

Shock spread across Ben's face, making me smirk. "You mean..."

I didn't give him a chance to ask questions. I opened my door and worked to get my body out of the car, then began to waddle towards the store.

It was crowded on a Sunday afternoon. The most public messing around Ben and I had ever done had been in a car in an empty parking lot. This was a lot different. But I wanted it bad.

My bladder really was aching as I made a beeline for the single-occupancy family restroom. I felt eyes on me as I shuffled through the store; in my eighth month my pregnancy was a public spectacle. I wondered how people would look at me in six weeks when I was full term. I wondered how people would look at me if they knew I was carrying my son's child in my belly.

Luckily the bathroom was unoccupied. I went in, locked the door, and did my business. I hadn't even looked back to see if Ben had left the car. Would he really do this? Come fool around with me in a public bathroom while his girlfriend got her nails done?

Soon I had my answer: two slow knocks at the door. I unlocked it and Ben stepped in, looking as excited and nervous as the first night we made love. "What are we doing, Mom?" He asked.

I locked the door behind him. "We don't have much time. No more teasing."

"Okay," Ben smiled, and reached for my breasts.

I gasped with pleasure. It felt like it had been years since I'd had Ben's hands on me. I had foregone a bra so we could do this easily, and my nipples were instantly hard under the thin soft fabric of my dress.

"They're so huge," Ben whispered, massaging them, lifting them.

"Bigger than Kayla's," I whispered back, and he went red. I planted a kiss on his lips while he groped me, stoking the fire that already burned between my legs. My body had a primal need for his. He was my mate. I had his baby in my womb.

He kissed me back forcefully, squeezing my breasts hard enough that it hurt. I winced, but I loved it. He desired me. He wasn't just doing what Mom told him to. Even with a cute young girlfriend he wanted me. When I wrapped my arms around him I could feel his hardness against my stomach and I moaned.

"You still want me," I breathed into his ear.

"Mmm-hmmm," he murmured back, his fingers tweaking my nipples through my dress.

"You want my tits. You want my milk."

"Yes," he groaned, pinching my nipples.

"I don't want to get this dress wet," I said, pulling back. While he watched, I reached under my neckline and scooped out first one heavy breast, then the other. They hung down low, my nipples pointing down, but they were enormous and my son practically drooled as he looked at them.

"Oh my God," he grunted as he took one of them in both hands. "How big are they?"

"E-cups," I reported, a proud smile on my face. "How big are Kayla's?"

"Mom," he groaned. He was probably feeling guilty.

"Sorry, we don't have to talk about her."

He played with my fat, dark nipple. "B-cups."

"She's very cute."

"You're cute, Mom. You're hot." He was pinching the nipple again, trying to get the milk flowing. I took my other breast in my hands and showed him how.

"Like this," I said, gently massaging my upper breast. I shivered as I felt four hands on my chest at once, Everything was so sensitive. I got a drip of milk first, the wetness shining against my dark nipple under the bright fluorescent lights. Ben stared at it hungrily, then pulled at my other breast until a droplet appeared.

He leaned in and sucked my nipples clean, one after the other. I bit my lip. My hips rocked without me even thinking about it. Ben chose a nipple and sucked gently, coaxing out more thin colostrum. "The real milk will be in after the baby comes," I told him, my voice quavering.

He just kept sucking, his tongue twirling around my nipple, driving me crazy. My breathing got heavy and I stroked his hair. I felt a release of pressure as my milk dribbled into his hot mouth.

Finally he released my nipple and looked up at me, smiling ear to ear. "What do you think?" I asked him.

"I can't believe you're making milk."

"It's because of you," I said, taking one of his hands and moving it to my bloated stomach. "It's for your baby."

He shivered at that, and went back to suckling. With both hands he rubbed the massive expanse of my baby-filled stomach. I knew our son was awake, responding to my excitement, the hormones in my bloodstream. Ben groaned when he felt a kick, the vibration in his mouth tickling my nipple.

I wanted this to last forever, Ben kissing me and sucking my breasts and feeling every curve of my pregnant body, but I knew we didn't have much time. I was praying nobody would knock on the door.

"Ben," I hissed, but he was lost in thought, intoxicated by my breasts and my belly. "Ben!"

He looked up but didn't let my nipple go.

"Fuck me," I ordered him, and that got him moving. He released my breasts, both my nipples huge and wet now. I turned around and grabbed the sink with both hands. I watched myself in the mirror, my engorged tits hanging out, my face flushed. Behind me my son lifted my dress and made a surprised sound when he found I wasn't wearing any underwear.

I wiggled my butt at him, teasing him. My hips were wider than ever as I prepared for birth, and I knew my butt had gotten huge. I had stretchmarks on my ass. I spread my legs and bent down.

In the mirror, I watched Ben marvel at my body, then undo his belt. I licked my lips when he took his dick out. It was hard. Ready for me. Kayla might have been younger, smaller, more agile than me, but I bet she'd never fucked him in a public bathroom.

I felt him against me. He hissed with appreciation. "You're so wet," he whispered. I knew I was. I'd been hot and wet for him all day. His eyes met mine in the mirror.

"Do it," I urged, and he pushed into me.

It was a struggle to keep quiet. Ben's penis spread me open, filled me. I was so swollen down there it felt like he was twice as big. I could see from his expression in the mirror that it was intense for him too. He scrunched his face up as he started to thrust, like he was resisting his orgasm already. Like when we first started.

The sound of our breathing filled the little bathroom. We tried our best but we couldn't hold back our moans, our grunts. My toes curled in my shoes. I'd never done anything this nasty. I looked at my own reflection, my swollen tits bouncing with each thrust, my hair mussed, my baby bump hanging low. I was nasty. Disgusting in the best way. Fucking my son in public. Carrying his child. Letting him taste my milk.

I'd started the year as a nice normal mom. What had happened. How had I ended up here? Sometimes it felt like I wasn't in control. The feeling I got as Ben filled me up was so powerful I just had to follow it.

"Harder," I told him, and he picked up the pace. Our bodies made a sound as they smacked together over and over. I could feel his balls slapping against my mound, teasing my clit. Underneath me, Ben's son squirmed and kicked at my ribs. I'd never felt so full. My body felt huge, and with each thrust I imagined Ben somehow making me bigger. It felt powerful. I had my own gravity, pulling my son into me. Away from that skinny young girl.

He had his hands on my hips, shoving himself in as deep as he could, but I wanted him deeper. I pushed my butt back into him and he let out a real moan, a loud one. He took a hand off me and clapped it to his mouth. I laughed.

He slowed down and I warned him, shaking my head. He'd been teasing me all weekend. He'd been away from me for over a month. I wanted what I wanted.

So Ben sped up, slamming into me as hard and as fast as he could. I almost lost my grip on the sink but luckily didn't fall forward. I watched him intently in the mirror and told myself I needed to put a big mirror up in my bedroom just for this. It was so unusual to be able to see him like this, under the bright lights, his clothes on.

My back felt tight, threatening to spasm as it held up my weight. My legs were weak beneath me. As much as I wanted this to go on all day, it wasn't sustainable. I looked up and met my son's eye in the mirror.

"Are you close?"

"Yes," he panted, seeming frantic. Like he'd been fighting his orgasm since the second he entered me.

"Do it," I told him. "Come for me."

It didn't take much more than that. Ben grasped my hips and went at me with abandon, making me squeal with pleasure. I worried I'd rip the sink right off the wall, but it held. My son's expression changed as we pushed him past the point of no return. He at least had the peace of mind not to scream or bellow, instead emitting a series of low growls as he emptied his balls into my body.

Warmth spread through me as he came. The feeling of his orgasm, the knowledge that his sperm was swimming up into me, never stopped exciting me. I was close to my own orgasm, but with my belly in the way I couldn't reach my clit. I let Ben finish, his strokes finally slowing until he came to a halt. We were out of breath but I needed to keep up the momentum.

I pulled away from him and he stepped back, his penis exiting me with an audible pop. His seed dribbled out of me onto the floor. "Finish me," I commanded. "I'm so close." I turned around, leaning against the sink, leaning back so my belly was in the air and he could reach under.

He was still twitching and shivering from his own climax as he dutifully reached under my heavy stomach and found my swollen pussy. I could smell it in the little bathroom. Our scents mixed together. He touched my clit with two fingers and started making circles.

I watched him work, face to face this time. I watched his softening penis, still hanging out of his pants. I thought about his baby inside me. I thought about his girlfriend waiting for our return. I finished in no time.

Ben had to press his other hand to my mouth to stop me from alerting the whole store to my orgasm. I made a mental note that I liked it. I'd ask him to do that again. I moaned and groaned against his fingers as an outrageously powerful pleasure shook my whole body. My legs wobbled and Ben had no more hands to catch me. Luckily there was no stopping my climax, and it kept going as he removed his hands and took me by the shoulders, guiding me down onto the toilet.

"Jesus Christ," I panted as I recovered. "Let's not go another month without doing that, okay?"

"Okay," he smiled, and I knew he meant it. He'd missed this just as much as I had.

It took a few minutes for us to get our bearings, to wipe Ben's mess off the floor, to put our parts away. I looked in the mirror, sure whoever saw me would know I was freshly fucked. I was glowing, but not because of the pregnancy.

"You leave first, baby. I'll meet you in the baby section," I told him.

"What?"

"We still need that changing table. We gotta rush."

Ben was in a daze. We left the bathroom one at a time, finding nobody waiting for it. He carried the heavy changing table through the store and we checked out, and the whole time he had a dumb smile on his face. I could feel the love between us, the connection. He was mine.

"I mean it, Ben, I'm not trying to break up your relationship," I told him once we'd loaded the changing table into the car and started the engine. "If Kayla makes you happy, that's great. Don't think of it as cheating, okay? Think of it as helping your mom."

Ben still had that grin on his face. He put his hand over my knee. "You know I love you, Mom. I'm always going to be here for you. Whatever you need."

If we hadn't been in the busy parking lot I would have kissed him on the lips and started the whole thing over again. But we needed to pick up Kayla.

Ben kissed her when we got back to the salon, and told her she was beautiful with her new nails, but it didn't bother me. I was proud that he was a good, loving partner. Things seemed normal as the afternoon passed and we got lunch and made chitchat and before I knew it it was time to drive them back to the bus stop.

Kayla hugged me and told me it'd been great to meet me. I told her the same, and I thought about her boyfriend pumping into me from behind. I thought about how I still had his seed inside my body. I thought about that dumb smile he couldn't get off his face. And as they got onto the bus, hand in hand, I felt great.

Ben would be back. I drove home as fast as I could so I could fantasize about it
