In her sleep

When John arrived in Audrey's bedroom, night had fallen for a while now. He discreetly opened the door and recognized the silhouette of his sister on the bed, snoring softly, oblivious of the threat that had just arrived. She was only wearing her nightgown and one of her large boobs had come out of it. John remained silent next to her bed, admiring her curves, before bending forward and kissing her on her lips.

-Hmmmm...

He saw Audrey open her eyes, startling, trying to fight back.

-Ewww, what the hell do you thing you're...

-Sleep, John whispered.

Audrey's eyes suddenly became glassy, before closing completely. Her head fell backwards, and she resumed sleeping. Slowly, John climbed on her bed, freeing her other boob from the nightgown. He started squeezing them, kissing them, sucking on them, pinching the nipples until they started to harden. Then, when he got tired of just playing, he pulled down his pants, bent forwards, and tightened his grip on his sister's heavy tits, before pressing his rock hard cock between them. For the next few minutes, his lower body went back and forth, while he was giving himself a nice titty fuck from his sleeping sister's breasts.

-Hmmm, moaned Audrey, still asleep.

-Shhhh, good girl.

When he finally unloaded, his cum landed on her throat, her chin. He grabbed some with his hands, before spreading it on her face, like some kind of strange beauty mask. Audrey's pretty face was now smelling like cum, but she hadn't noticed anything.

John wasn't done with her, but he decided to take some time to reload. He went down and lifted the nightgown, revealing her shaved pussy.

-Not wearing any panties, huh?

As an answer, Audrey just kept sleeping. John smiled, knowing nothing could possibly come to interrupt him now.

-Slut, he added.

A moment later, his tongue was playing with her clit, while his index and middle finger were starting to enter, barely at first, then deeper and deeper. Audrey's moans got louder, as if she was having a really intense wet dream. He could feel her clit swell under his tongue, as her breathing accelerated. Once in a while, she would squirt without a warning, wetting the bed again and again.

-Damn, you're quite a squirter, aren't you? I'm sure you'd love to be conscious right now.

-Hmmmmmm, Audrey moaned, before projecting another dosis of her juices.

After ten minutes of foreplay, John finally felt ready to do what he had come to do. He climbed back on top of his sister, grabbed his dick and without hesitating any longer, started fucking Audrey, who was incapable of doing anything to stop him. Given her loud breathing and moaning, her body seemed to be enjoying it a lot. For another fifteen minutes, he kept thrusting, thrusting. He had something in mind, something fucked up, of course, and he couldn't wait to see her reaction.

When he finally came, filling her cunt with his cum, he bent forward until his mouth was right next to her ear. Then, just as she was sighing in relief, he whispered.

-You're pregnant. With twins

He felt his power rushing through his body, before hitting hers. He knew she was expecting his children now.

-I am accelerating the process. By tomorrow, when you wake up, you're in for a little surprise.

John kissed his sister's big boobs one final time, before leaving the room, glad to have finally fucked this chick he had been fantasizing about for years.

8 hours later

*********************************************

-Hmmmm...

Audrey moaned, as she was slowly waking up. She stretched, her mind still hazy, vaguely focused on those amazing dreams she had had this night. They had been so intense, so realistic.

-Hmmmm, why can't anyone fuck me like that in real life? she moaned, before trying to sit on her bed.

This is when she realized something was wrong. Usually, sitting had never been a problem for her. But now, it felt as if she was carrying a heavy bag in front of her. She looked down and gasped. There was something huge and round under her blanket, and...did something just kick her? Trembling, she removed her blanket, and screamed.

-Oh my God !

She clumsily jumped on her feet, and almost lost her balance. Her belly was swollen to an impressive extent. It had torn her nightgown apart. The latter fell at her feet, leaving her naked, her now even bigger boobs hanging freely. She saw herself in the mirror and started shaking. What happened to her? She looked 8 months pregnant. Her face had swollen, her belly, her boobs...and was that milk coming out of her nipples? She touched her belly, but immediately removed her hand when she felt a kick from inside of her. Hyperventilating, she reached for her desk in order not to fall, before looking around her in despair.

-Help ! Somebody help !
