Becky decides to sleep with you in your bed

By: Cheese111

You didn't have the strength or willpower to do anything more than lie still. Your body was too ravaged by Becky's oversized cock to act beyond sputtering and twitching as your insides tried to somewhat reorganize themselves. Your girlfriend stood looming over you, rubbing her slightly softened dick back to full mast. Her initial plan was simply to go for round two, but seeing you lie there, so pathetic and cute, gave her a different idea.

"Oh? Are you cold?" She asked, leaning in closer. Her voice was dripping with malice already. You tried to politely decline, but couldn't respond with anything more than a stutter. "N... N... n..."

"Hush, little Willy. It's okay. I'll keep you company for the night." Even in the pitch darkness you could tell she was carrying a cruel grin. You just knew it.

Becky didn't go for a particularly subtle approach either. She draped herself on top of her boyfriend, smothering him beneath her belly and chest. You'd received a full-body embrace like this before when she and Kim got intimate with eachother. But now you were big enough for it just to feel a bit overbearing instead of being painfully crushed by your girlfriend. Whether good aim or coincidence, her soft breasts ended up pressed in your face. For a brief moment it actually felt kinda nice. But when you felt her hot shaft bump against one of your legs you knew this wasn't going to last. Becky's arms wrap around you and like a constrictor snake descending on its prey she held you tightly against her body.

Your face was wedged deep between her breasts, their exaggerated size helping them engulf most of your head. Were it not for Kim's treatment you're certain you could suffocate in here. You feel the two of you slip beneath the blankets for warmth, but Becky wasn't done with you just yet.

"Still cold? I guess drastic measures will have to be taken." She said, smiling with malicious glee. There wasn't a hint of shivering left in her boyfriend, but she wasn't about to let such trivial things stop her. She knew what she wanted. A gentle push dislodged you from her breasts and you feel her smooth body sliding against yours. With a dreadful sigh you knew where this was going. But against her firm embrace there was little you could do. She subdued any struggles with ease as she felt the tip of her cock drag along the inside of your leg.

Your ass was still recovering, unable to close fully after being **** open by that mammoth dick. And here it is again for round two. With remarkable ease it pushes in, the bulbous cockhead demolishing all resistance. Any cry for help is stifled into a soundless gasp as Becky pumps herself in deeper. Each thrust made you wince as you could feel the solid girth of her cock ram itself in hard. Pressure made way for pain as she fucked you again. Though the different position meant she couldn't thrust with as much ferocity, sheer size alone was more than enough to make this a living nightmare. Moreover, she made absolutely no impression of pulling that monster back out anytime soon.

Becky grunts, struggling to keep the volume down on her moans. It just felt so good to pound that cute little ass. Tomorrow she'd ask Kim to make sure you stayed this small. For now she just whispered in your ear. "All snug and warm, aren't you? I know, I love you too." She cooed, pushing herself in up to the hilt. She slowed down her humping, letting her rigid mast simply remain encased by your body like you were a living fleshlight to her. Any complaint from you didn't evolve past a pathetic whimper.

"Oh, hush now. It's time to sleep. I'll leave it inside you to keep you close all night long. But if you wanna try and escape I'm more than happy to flip you around and ram this thing down your throat for a couple of hours. How long did Kim say you could hold your breath again?" Becky's threats were somewhat undercut when she followed them with a big yawn. You were too exhausted to comment or struggle anyway, falling asleep with the huge throbbing beast of a cock still inside.

The next morning a distinct sense of dread washed over you. It took a moment to puzzle everything together, but the results made your blood run cold. The first thing you noticed was the relative scale of your room. Everything looked so... normal. You feel the backboard of your bed with your foot and reach up to touch the headboard. It felt familiar. You were back to your normal size. But not everything was alright. It didn't take long for you to realize it. The moment you tried to move again you felt resistance. True to her word, Becky had left you impaled on her huge cock all night long. But in spite of you growing, it felt no smaller. It's still buried deep inside you, and the only way that could've happened is...

You glance over your shoulder and your eyes widen in shock. Becky was there, but she too had doubled in size. Your girlfriend was now a casual 12 foot tall amazon sporting a cock almost as long as your torso is tall. Kim wasn't messing around when she warned of side effects, but you had the dreadful notion that Becky wasn't going to consider this a disadvantage whatsoever. You shudder at thought before letting out a loud yelp as she wakes up.

"H... Huh? Willy? What's going on?"
