It felt so real. So immediate. Everything swam around me. The girls all seem to waver as I felt myself rising and...

I came awake, holding my little sister in my arm as my cock...

Sank into her pussy.

"Allie?" I groaned. I opened my eyes, my nipples throbbing in her back. "Am I... in your pussy?"

"Yep," she said as my cock bottomed out in her.

"How did that happen?" I asked, confused.

"Oh, well, you woke me up by humping my ass."

"I was humping Mrs. Greene's ass," I muttered.

"Ooh, do you have a thing for your teacher?" Allie turned her head. I could see the gleam of her eyes from the light bleeding through my window. "Are you going to fuck her."

"Of course not," I panted. "She's my teacher. And married."

"Her daughter is a slut."

"Well, doesn't mean she is," I said.

"I guess not." Allie sighed, her pussy squeezing down on me. "Not like our sisters are into incest or anything when we are."

"You are," I said. "I'd never thought of any of you like that until today."

"Mmm, but I awakened it," she said. She giggled. "Come on everyone's asleep. I can be mostly quiet. Work that cock in and out of me."

"You naughty minx," I purred. I slid my hand up and squeezed her small breast. "You're lucky your tits are cute as fuck."

"Oh, are you saying you have the willpower to slip your cock out of my pussy now?" she asked.

I bit my lip. "Well..."

"That's what I thought." She squeezed her incestuous flesh around my girl-dick. "Come on, plunder me."

I couldn't resist that.

I drew back my cock and then slammed it into her pussy. The bed creaked as I made love to her lying on our sides. My crotch pressed into her rump on every plunge. The strokes weren't as hard or fast as they could be in another postilion. It was almost a slower pace.

I savored the feel of her in my arms. I groaned as I nuzzled into her hair. I kissed the top of her head and breathed in the scent of her. I shuddered, my nipples throbbing against her back as I pumped my futa-dick in and out of my little sister.

The twins were just on the other side of the wall. If one of them woke up...

My dick throbbed harder. The risk was so exciting. Allie made the cutest sounds. She quivered as her legs shifted. Her pussy squeezed and relaxed around my cock. My shaft's tip ached in her silky flesh. I pumped faster into her, burying my cock in and out of her.

It was a delight to enjoy her. A treat. My heart hammered in my chest. I whimpered and groaned. I pumped hard and fast. I slammed into her. I buried to the hilt in her juicy cunt. I reveled in being united with her.

"Jenny!" she groaned, her hands squeezing over mine cupping her little tits. "Oh, Jenny, your cock is the best."

"So is your pussy," I whimpered. "So are you. I love you!"

Her twat squeezed around me.

The pleasure swelled through me. I shuddered, plunging into her hot twat. At this angle, my dick's crown slid along the top of her pussy. The delight shot down my cock. I savored it. It was a wonderful treat to enjoy. It had me dizzy with excitement. I pumped away at her, my spongy crown drinking in the feel of her.

That wonderful, silky caress brought me closer and closer to my eruption. My pussy drank in the sensations flowing down my cock. I whimpered into her hair. I held her tight, rubbing my tits into her back.

Sparks flared from my nipples, shooting down to my pussy.

My ovaries brimmed with cum. They swelled, eager to unload into my little sister's fertile depths.

What would happen when she was pregnant? Did futanari syndrome breed true? Did we have normal girls that might one day transform into dickgirls? I had no idea. I shuddered, unable to stop myself from plunging into her.

"Jenny!" she groaned.

"Not so loud!" I panted.

"Mmm, it's hot, right?" She squirmed, her fingers pressing mine into her firm titties. "The chance of getting caught makes this so hot!"

"Yes!" I panted, my hips pumping in and out of her. "But we can't."

"No, no, but..." She squeezed her twat down. "Oooh, this is great. This is just the best. You're going to make me explode."

"Good," I panted. My cock throbbed in her depths. "I want to feel that. I want to feel you convulsing around me, Allie!"

"I will detonate!" she purred.

"Yes!"

I thrust faster and faster into her. I pounded her with my strokes. I buried my dick to the hilt in her. The pleasure flowed over me. It was this exciting delight. I whimpered and groaned, my nipples throbbing against her back. Pleasure sparked through me.

My juices soaked my bush. They spilled out of me as I drilled into her twat. I pounded her. Loved her. It was an incredible treat to enjoy. It was the best thing in the world. I savored it as I pumped deep into her twat.

"Oh, yes, yes!" she groaned. "Oh, Jenny!"

"Quiet!" I groaned.

Headlights flooded through our bedroom as a car passed on the street. Its engine so loud. Tires crunched as it pulled into a driveway. The car went off a moment later.

"But it feels so incredible!" she groaned. Her pussy clung to my dick, my crown aching. "I'm getting so close to cumming!"

"Me, too!" I whimpered. "But we have to keep it down."

"I love your cock," she gasped. "I'm getting so close."

I nodded, thrusting hard. I could feel the pressure building and building at the tip of my girl-dick. There was this moment I was approaching, this point that once I crossed it, nothing would stop the eruption. It was too late.

I drove towards it with every thrust into my little sister's cunt. She squeezed around me. Her silky flesh clenched and relaxed, massaging me. I leaned over her, kissing her as my ovaries quivered with my cum.

I hit that point of no return, driving my cock deep into her.

The garage door opened. I heard keys drop into the bowl. Footsteps crossed the floor.

"Mom's home!" Allie gasped as my futa-cock erupted.

The stairs creaked as Mom climbed up them. I clamped my jaw shut tight as my cum spurted hot and wild into my little sister's pussy. She squealed and trembled as I flooded her. Stars burst through the darkness of my bedroom.

Every blast of cum sent pleasure slamming into my mind. My heart raced as Mom reached the top of the stairs. I grabbed the blanket, hauling it up our naked bodies. My sister groaned and then her pussy spasmed around me.

"Jenny," she whimpered.

Through the light bleeding through beneath my door, a shadow fell. Our mother was right outside the door. The knob turned. I squeezed my eyes shut, trying not to whimper as Allie's pussy convulsed around my dick.

She milked me dry.

We were so busted.

The fear heightened my pleasure. Rapture burned through me. My pussy convulsed. Juices soaked my thighs as the light fell on us. Our mother stared at us. I could feel her as I kept my eyes closed, trying not to gasp out for breath.

"Oh, my," she said.

She knew. She had to know my futa-cock was buried in Allie's pussy. That her cunt was milking my ovaries dry of the last blast of cum. My little sister's cunt spasmed around me. The final blast of cum spurted into me.

Mom moved closer. I felt her over us. I trembled. She leaned down and her perfume caught mine. It was spicy.

"You two are just so cute," she said, her breath holding a faint tinge of wine. "I'm glad you're getting along."

My mother's hair brushed my face as Allie's pussy convulsed harder about my cock. I heard a smooch and then, a heartbeat later, I felt Mom's lips on my temple. I smelled a musk then, something faint. Was it Allie's pussy? Mine?

Could Mom tell we were naked beneath and had hot pussies?

"Sweet dreams," she said and then retreated.

The door closed.

I held my breath until I heard her bedroom door closed.

"Holy fucking shit!" hissed Allie. She bucked against me. Her pussy convulsed and spasmed. "Oh, my god, she had no idea you were flooding me. That was the hottest thing in the world!"

"Yes," I panted. "Oh, my gosh, we were almost busted. That was the way to close."

"It was perfect," whimpered Allie.

"But... but... what if she realizes she smelled our pussies. What if she realizes our clothes are all over the floor?"

"You worry too much," Allie said, squirming around. She rolled over, my cock popping out of her juicy twat. "Mmm, we got away with it."

She faced me now, my cock throbbing between us. She threw her arms around my neck and pulled me closer to her. I stared into her eyes. She was right. We'd gotten away with it. Probably. But we'd have to be careful.

When Mom was home...

And what about college tomorrow? Things were about to get crazy. I clung to my little sister, panting as I came down from my orgasmic high. Becoming a futanari had made everything vastly more complicated.

Allie slipped into sleep almost immediately, a smug smile on her lips. I shuddered, worries gnawing at me. How my friends would react tomorrow? The other students? Would Mom or the twins find out Allie and I were making love?

And if she became pregnant...

Sleep was a long time coming.
