Your father slept in your room

You wake up with a dry mouth, a bitter groan leaving your lips as you rub the sleep out of your eyes. What had happened yesterday?

Opening your eyes, you find yourself lying on your back under the bed covers with your legs painfully wide apart. As you grow more aware of your surroundings, you also hear... a snoring noise by your side. Huh? You glance over to the other side of the bed and see your dad sleeping there on his side while drooling onto the pillow. That's... weird.

You remember having had some vivid dream during the night. It was pitch black in your room, but somebody woke you up by stripping you... and then having sex with you? Oh no! Your hands grab the bed covers and you toss them off the bed, revealing your painfully swollen vag. It was a dark shade of red, and your inner labia were protruding noticeably. It looked completely broken and damaged compared to the subtle, pale slit from before.

You had sex! With your dad! Wait... and you are still a girl? With a quick glance towards the nightstand clock, you feel reassured that it was only six o'clock. Another hour before you change back.

There was some stirring by your side, and you felt your dad moving his hand around your waist. "Good morning. Sarah, right?" He yawned and placed a kiss on your shoulder. "I don't know what got into me last night... I hope you liked your birthday gift." His gaze went down to your thoroughly abused womanhood. "Looks like your classmates will have no doubt that you had your virginity taken care of." He gave you another kiss, and slid his hand down to your labia to playfully tug on the abused flesh - any trace of elasticity however was completely gone. From what you remember, he did take you particularly hard and rough, your female equipment probably wasn't meant to handle an adult's cock like that.

Good thing you weren't stuck as girl, your pristine body was the only upside of this deal, and now it's damaged beyond repair. "Yeah..." was the only reply you could meekly come up with. As he dipped his finger between the sore folds of your twat, you winced. "Just... how many times did we.. uhmm... have intercourse?" you ask with a mixture of shame and confusion.

"Just once, but you're a woman now." His voice was confident and pretty full of pride. He must've enjoyed getting some teenage pussy after years of being married, and he released all that pent-up energy in a single night of ruining your battered womanhood. "My balls are itchy though, I don't think I managed to cum yesterday after so much beer... how about you help me out," he suggested as he already began climbing on top of you and kicking your legs apart to make room for himself. His experience was pretty evident, he was completely casual in his behavior.

He reached down with his hand, and jerked his appendage while keeping the bloated cockhead against your soft pubic mound. After your initial lack of interest, you get your first decent look at his tool, and it's massive! Angry red and veiny, with a girth as fat as your wrist. He didn't simply take your virginity with that thing, he brutally erased it! He's beginning to lower the purple crown of his appendage to your entrance, and shoves his weight forward to roughly enter you once again.

"Ahnn!" Your bed creaks bitterly while you're struggling to accommodate his shaft. Unlike the day before, you weren't completely blinded by lust after hours of masturbating. Your vag clearly wasn't ready for this, and was still extremely sore to begin with, everything was stretching and hurting to make room for his bloated rod.

He began to move back and forth mechanically at a steady pace, your old bedframe squeaking in response to every thrust. The warm comforts of your cunt were wrapped tightly around your dad's dick, and squeezing down hard on him however much you attempted to relax. Each time he pulled out, your lips were gripping his shaft outwards and probably loosening further in the process. You're surprised to hear your phone beeping in the middle of it all, and reach over to your nightstand to grab it while your father is still on top of you and pounding away. Let's see... Gwen sent a message?

I hope you don't mind the white lie about dad having a vasectomy. I can hear your bed! Sounds like you don't mind being female! I hope you got a girl growing in your belly, then we'll be three sisters!

Huh? What does she mea- oh no. Right then, your dad interrupts your thoughts. "I hope your little Sarah down there is ready to drink up her morning milk," he announces with a lighthearted smile, followed by a familiar, loud groan as he shoves his hips forward, tightly mashing his crotch against yours, your swollen pussy lips kissing the base of his cock. "Little Sarah...?" you ask naively.

Upon looking back down, you're shocked to see that he had buried the entirety of his erection in your baby chamber. The only hint of what was going on was the subtle pulsing of your labia in tune to the immense throbbing of his cock - he was already cumming! Each pulse made your pussy lips jiggle just enough to make it appear as if your cunt was actively swallowing down the gooey gift.

"Ah that was nice." His strong hands move down to grab your perky butt cheeks, and he presses himself even more tightly against your petite body, casually using your genitals to milk out every last drop of his gross sperm. His vile organ was still throbbing lightly. Crap! You need to get that stuff out of you immediately! Otherwise Gwen may get her wish after all, and you would end up having your own sibling growing in your belly for the next few months!
