Day 3 - Safe sex wins the day

The two of you end up fucking throughout the entire night, or rather, she continued fucking your cunt while you lay back and allowed it to happen. Considering how sore you were, it wasn't possible to enjoy the process a whole lot. Still, your mother insisted on making the best out of the remaining time and pounded you into a senseless mess until the wee morning hours.

Each time she came, her loads got smaller and smaller, until the condoms contained barely any fluid anymore after each climax. She seriously managed to completely empty her balls, that's an accomplishment by itself...

It's at some point when the sun begins to rise again that you simply collapse. It felt like you dislocated your legs from spreading them so much, your pussy was tenderized, and you happily accepted the offer when your mother suggested you should rest your head on her lap. A pile of discarded condoms by your side made the entire tent reek of sperm, latex and pussy. It had been one crazy vacation, and a story that you will likely take to your grave.

She absent-mindedly rubbed your breasts while looking at your cute, young body. "You know, it's a shame that you will return back to normal again soon. I had one hell of a time during the past few days. Plus there's so many things I'd still love to do to you! For one, your tits are nice and all, but with some implants I'm sure we could get you some DD's, maybe even an H-cup. With some laser treatment, we could permanently remove your pubes. Keep you nice and hairless. Who knows, with some pills you might even be able to get pregnant? Once you start producing milk, these boobs would seriously grow into some nice big jugs!"

You quietly laugh at that last comment and shake your head. "Hell no that's just... not something I'm into." While she still caresses your breasts, you decide to finally tell her the whole truth. After all, there's maybe a few minutes left before you change back - and after an entire night of fucking, her dick was just as soft and tender as your cunt. There is absolutely no way that she will be able to get it back up for the next few hours, or rather, until it disappears.

"I'll be honest with you. I was able to get pregnant the whole time. It's directly related to the curse, if I get knocked up, everything would remain as it is right now. That's why I insisted on using condoms in the first place, one close call was enough to make that decision." Even after stating that, you could feel her girl-cock remaining completely flaccid. She wasn't going to get it up again anytime soon.

"Really!? Why didn't you tell me? That's hot!" She pouted back at you and was visibly unhappy about her lack of choice in the whole matter. "So I simply would've needed to cum inside your snatch and we would get to stay like this?"

"Y-yeah. We would have to stay like this, which isn't an appealing thought, you know. I don't like being a girl. My vagina gets sore faster than I can say 'ouch', my breasts are an annoying extra weight on my chest, I don't like having to squat down to pee, I dislike having zero muscles, I..." while ranting on and on, your mother leaned back a little and retrieved one of the discarded rubbers. It was fascinating to her that the curse had the potential to last forever! Having a cute, fuckable daughter would be really hot, but getting her own daughter pregnant? That's the jackpot of fetishes! Still, there was no way she would be able to get her erection going again. But there's other ways...

"You forgot the most important part, girls also have the bigger responsibility as far as birth control is concerned," your mother points out. "See," she explains as she takes the condom and turns it inside out, revealing the slimy mass of sperm covering the latex surface. "A boy only has to worry about getting his dick wet, but the girl always has to worry about where he's going to cum, and where that cum may end up afterwards. It's never safe, really." She slides two of her fingers into the condom, moves her hand down to your crotch, and suddenly shoves her latex-covered fingers into your twat!

"Ahnn! Seriously?" You look down at your pussy, and watch the way she gradually wriggles her fingers inwards. "It's uh... a bit late for that... I'll be changing back any moment, so drop it. It's not even funny..." you point out, but she continues on. It's weird for her to even try, it was too little, too late. You know that you won.

"Really? I can't imagine that you will change back while I've got my fingers inside you. Plus, you should know that sex isn't a requirement to get pregnant. It only takes a single, strong swimmer." Yet, visible to both of you, the reversing changes began by your chest. Your breasts slowly shrunk from their initial D-cup down into a C. Both you and your mother look further down, but your pussy stays intact - for now anyway.

"M-mom! Can't you see? It's too late, just let me change back!" Instead of complying with your demand, she snakes her fingers even deeper inside and you can feel her bumping against your cervix, eliciting a groan out of you! "Ouch! Too deep! S-seriously now, stop it!" you demand yet again while trying to squirm out of her embrace, but she was having none of it. You could feel her using her slender fingernail to wriggle parts of the condom right into the tiny opening of your cervix, slathering it with remnants of sperm.

Your breasts continue shrinking into a B-cup, but from the waist down, still nothing changes. If only you had any strength left to fight her off, an entire night of sleepless fucking drained everything you had, yet your mom somehow found a new source of energy. With the help of her nail, she gradually managed to coax small parts of the semen-dripping condom through your cervix and into your womb, a sensation like a thousand needle pricks at once, focused entirely on your abdomen.
The reversal causes your breasts to shrink into a small A-cup, until suddenly everything just... stops? Like a defect wristwatch, everything seemed to freeze and only your rapid breathing could be heard? What's going on?

You were no longer changing back...? One of the countless tiny sperms managed to find an egg somewhere inside your loins... your own mom knocked you up. How is that even... in a matter of minutes, you went from having a completely sperm-free vagina, to being freshly pregnant. She was either incredibly skilled, or really lucky... or perhaps a mixture of both. Shit!

She won... with a gleeful giggle, she leaned down to place a kiss on your cheek, and then on your significantly smaller boob. "Happy conception day! Does this make you my dirty little secret, or my new girlfriend?" You bitterly groan back at her, and with a wicked smile she simply kept her fingers knuckle-deep inside your cunt for a little longer. A reminder that you will never regain your manhood.

You can't even begin to imagine what your future may be like...
