What's next?
Day 3: A sister's choice, normal life or FWBs?
While feeling your father's manhood rubbing up and down along the fleshy cleft of your cunt, trying to find the hole that leads into your most private and most feminine body part, you're fortunate enough to remember that you planned to be the one in charge, the one in control! Your whole plan hinged on him believing that you are completely experienced and without a care in the world! Especially now that Gwen was trying to use the morning after pill as a bargaining tool! If you want to act confident, you're gonna have to do it quickly.
"Come on big boy, let me help ya." You reach down with your slender hand and grasp the tip of his erection. With another fluid movement, you begin peeling back his foreskin to reveal that particularly sensitive purple crown of his manhood. The protective skin is easily slid back far enough for it to get stuck behind the fat rim of his cockhead. Exposing the engorged crown that so eagerly wanted to return into your twat.
You then spread your legs a little further -- just a tad -- enough for your labia to open like an innocent flower and you use the chance to guide his tip down to your unprotected entrance, the tiny opening into your slit. This time you didn't hesitate, you simply pushed him up against the hole and used your thumb to easily plunge him inwards, connecting your two genitals. Just a woman and her man. "There you go, safe and sound back home," you comfort him reassuringly. After all this was your choice and you are merely allowing him to use your vag. Gwen kept her end of the deal and leaned over to feed a pill into your mouth. "To help you re-relax..." You happily oblige and swallow it.
Father didn't waste time and immediately sunk his entire girth into your pussy, stretching you deliberately until you accommodated every inch of his massive rod! You barely manage to suppress a defeated groan, the discomfort was intense as fuck. It's like someone shoved a fist into your loins! If there were any doubts before, it's now clear as hell that this petite body wasn't meant to have sex with a full-sized adult! The stupid witch had probably intended for you to get laid with someone of your age instead of someone old enough to be your dad. Literally. His thrusting was rather dull at least, he was jamming his cock into you at the same rhythm over and over. Each shove forward managed to lure a liquid squelch out of your tender pussy. It was monotone and mechanical, but then again... sex isn't like in the movies... you already realized that much when you didn't gain any pleasure out of having his dick occupying your insides.
Your distraction has another unexpected side effect. You were so caught up in your own thoughts that you hadn't even noticed that your father ALREADY had stopped thrusting into you? Had he been close to climaxing this whole time already? And his ball sack was twitching rhythmically... ohh! Fu-fuck! This is it!! Your first creampie, delivered straight into the deepest corners of your teenage cunt... !!

You awkwardly decide to just... stay motionless. Letting him do his thing. Letting him enjoy the grip of your pussy to milk out every drop of semen that his manhood had to offer. At least the clean-up will be easy when he's done... he is spilling his seed so deep in your loins that there's no way for any of it to ooze out naturally anytime soon. Your entire vulva is concealed while he's keeping his sweaty and hairy crotch pushed TIGHT up against your lady parts. It was almost painful how firmly he was keeping himself pressed against your sore cunt lips! Right now, your genitals were perfectly fused together to allow his seed to travel directly into your birthing chamber. His mature cock throbbed and thrashed against the velvety soft embrace of your innocent vag. Oddly enough, against all expectations and things you've read in those erotic novels, you can't really... feel anything distinctive going on down there? You were vaguely aware of the pulsing of his shaft, but the cum? All that risky sperm that he was shooting into you? Can't tell if it's in there... ? So weird. It's basically just body-warm liquid, so... it kind of makes sense that you can't feel it inside you. Lord knows there's plenty of fluids in there already so maybe you just can't feel the addition of even more...
Ironically, there was more than enough inside you now. Millions of his sperm, each one filled with his incestuous DNA, were already swarming inwards and pooling around your tender cervix. At least a few thousand already managed to enter it and were rapidly swimming right through and towards your womb. Their small tails were swinging and swaying like mad! So excited to try and find the egg that may already be waiting inside your fertile teenage loins.
His heavy testicles kept pulsing, but still... you can't feel anything special. Sex as a girl has really been a letdown. In porn they tend to climax as soon as the dick pushes in and typically get their 4th orgasm by the time the guy climaxes. Reality doesn't seem to be nearly as special! It was rather... boring and blunt. In fact... yawn .... you're starting to feel rather tired? It's probably a good idea to wash the sperm out of your vagina and take another morning after pill before going to sleep.
As you look over to Gwen, you can see her sensually biting her lower lip, eyes nearly closed, and even with the blanket covering most of her body you could see her thrusting her hips forward and into the grip of her hand. Her little girl-cock was probably in the midst of making a mess too. She had really enjoyed watching you take your first dick. It's unfortunate that your dad was the one to break your virginity and bless you with the first fuck of your life. Of course it's even worse that he took your creampie virginity too, you will probably never forget that you had your daddy's little swimmers occupying your fertile cunt. Well, you still do as a matter of fact. Lowering your gaze, you can see your tummy bulging lightly with the sheer amount of sperm he had deposited within your undersized lady parts!
With a weary and completely exhausted gaze upwards, you can see your dad still busy on top of you. His testicles were still twitching like crazy. He was really packing your cunt full of his sperm. There wasn't a single drop he wasted, and your vag had **** but to swallow it all, drinking it in deep. What's even more strange is that it didn't particularly bother you anymore -- you felt rather... comfortable and at ease. "That's it big boy, just let it all out inside me," you encourage him. "I don't mind anymore. I'm safe."
"Not ye-yet..." Gwen interrupted. Slightly confused you look back at her. "It was a pill to make you relax... not a morning after pill..." she explained. It's not like she had even pretended to give you a plan B pill earlier, that was just your assumption. A wrong one. Without drawing your attention earlier, she had taken some particularly potent anti-depressants out of her backpack and fed you a double strong dose! Enough to dull your emotions and drop your guard...
And they sure had the effect she hoped for.
"Oh... I guess that's fine too." Nothing to worry about, you can still take the protective pills later on, right? It's hard to tell why you were so anxious earlier. Your dad's dick was still wedged snugly against the back of your cunt, he wasn't gonna leave a job half finished. Your vag was wrapped around his cock like a fine latex glove and he was making sure to cream your pussy to the best of his abilities. After all, you were just a little girl who didn't know any better. He was well aware of how the plan B pill wasn't a flawless get-out-of-jail-free card even after you finally get to swallow one. As long as he tries hard enough, he WILL get rewarded with seeing your flat belly grow and swell.
He still had no idea that you are his son -- currently trapped in the now **** body of a girl -- the girl he was so eagerly trying to impregnate! His dick twitched again, delivering a last glob of his thick cum and slathering it all across your cervix... it was now thoroughly coated with that disgustingly cloudy, pearly white goo of his...
The tent was beginning to fill with the musky and far more obscene smell of unprotected sex, consisting of a vile mixture of cunt aroma, fresh sperm and sweat. Of course he was still under the impression that you're an experienced girl, so why bother holding back or trying to make intercourse feel more special than it really is? Since he was still keeping you in that awkward, folded position it was easier to focus and feel the constant shifting of fluids somewhere inside your belly. "Man, my pussy feels... wet as fuck. Did you explode a water balloon inside me or something?"
Your father grins in response and seemed pretty... relieved to see you acting more at ease. He hadn't noticed that Gwen stuffed you with those mood dampeners. Your original personality, the one full of stress and worries, had been suppressed almost completely. Of course the medicine had been designed to help people with random panic attacks -- it's an entirely undesired and unexpected side effect to make a girl ignore the dangers of bareback sex!
"Glad you liked it," came his reassuring answer, his voice still dark and aroused. Clearly he didn't often get the opportunity to fuck and creampie a young and nubile girl like yourself. Depending on how the curse worked, you might even look like a teenage version of your mother. Gwen certainly got her wishes fulfilled as well, the mood was mellow and easy. Just like a pair of friends with benefits who just got done fucking. He finally withdrew from your sloppy cunt, a wet pop followed and was accompanied by a bubbling of warm semen as it nearly leaked out of you. Gravity coaxed the gooey mass of slime to recede and drool right back into your lady bits, making you shiver at the weird sensation. In porn, the guy usually pulls out earlier or spills some seed on the girl's belly -- it's weird to think that you've got literally every single drop of his entire load stored in the warm comforts of your fertile loins.
There's some muscle ache in your legs when he finally climbs off you and lowers your feet back down. He sure turned you into a woman, and he did so while your older sister watched to make sure you do your job correctly. Looking over to his side, you can see his erection slowly shrinking and going soft. It's weird to think that his dick had been deeper inside your vag than your fingers could ever go... "Well big boy," you begin. "Thanks for the ride, imma leave for a moment and get rid of the spunk you dumped in me." Time to follow your initial idea of squatting down by a tree and 'peeing' out whatever cum he deposited in you. He had other plans for you, of course.
Both of you were extremely tired and worn out. Especially your body was glistening with a fine layer of sweat. Getting fucked into submission was... taxing. "Just do it tomorrow, it's not going to kill you to sleep with a little bit of cum inside you," he pointed out reassuringly. The understatement of the year! You could still feel the gooey mass bulging against your belly. It feels like he transferred the entire contents of his ball sack into your little vagina.
Ah well whatever he's probably right. You reluctantly roll over onto your stomach, rest on the pillow for a while, and close your eyes while Gwen made herself comfortable nearby. It only takes a few minutes before the three of you fall asleep after such an exhausting evening... Still, you can't help but feel like you forgot something as you drift off to sleep...
Cum gradually leaks out of your deflowered slit during your slumber and forms a big wet puddle underneath your crotch. It's just remnants of his now empty seminal fluid, which is the stuff that makes up 90% of a man's ejaculation. The remaining 10%, the millions of actual sperm he dumped into your cunt, were still safe and sound inside you and swimming inwards...
The hours pass slowly. While your father was asleep, his sperm eagerly attempted to impregnate the defenseless womb of yours...

Gwen was the first one to wake up, to the sight of father and 'son' lying so close together after their recent evening fuck. The thought of her own brother's pussy being stuffed full of those wiggly sperms was enough to get her back into the mood to jerk off, and she spew another load of her cum into her blanket not long after. She did get another idea in the process... this was the ultimate taboo. Bareback **** without the slightest bit of protection. Leaving it entirely up to mother nature if her little brother ends up with a baby because of the carelessness...
But there's something she knows just as well. There's no way that John would agree to any of it once those anti depressants fade away! He would go back to talking about nothing but returning to his male body and hanging out with his male friends... blah blah blah... instead of happily wrapping his pussy flesh around daddy's fuck-stick. Wouldn't it be really friggin' hot to turn her brother into just that?
She considered her options -- letting the **** fade out of his blood system and allowing him to think freely and normally again... or feeding more **** into him just to keep him in that state with dull emotions. Without a care in the world. It's almost as if she's seizing control of your mind and making the decisions for you.
Gwen's fingers delved back into that package of anti depressants, snatched a pill, and gently lowered it down to your exposed, naked rear. It was so embarrassingly easy to spread the perky cheeks of your butt and insert the pill right there into your bum -- push -- where your body would easily begin to digest and absorb those helpful chemicals! Upon loosening her grip on your butt cheeks, they simply bounced back in place as if nothing had ever happened. With a glance just a tad further down, she could see your vagina still so bitterly red and sore -- properly deflowered -- and with a puddle of semen just under your crotch. It was then that she made the decision to keep giving you that precious medicine every. single. day. from now on...
After all, a hot girl such as yourself deserves only the best friends with benefits.
And even though daddy has that annoying obsession with getting young girl's pregnant, Gwen just knew that he would take very good care of your fertile cunt. You're gonna spread your legs for him, take his dick, and then carry his seed within your womb. Every single day. Gwen's girl-cock twitched and spilled another load of cum at the thought...
... needless to say, you never changed back into a guy... and you missed your next period.
