Gwen wants to fix the situation

Your vision goes completely black and blank while you're vaguely aware of a constant pulsing and throbbing throughout your body... it takes a solid minute before you regain your composure enough to open your eyes again. When you do, you see Gwen holding a tissue under her dick and it was soaked through with a huge load of white goo!

Both of you are panting after completely exhausting yourselves with just a single orgasm.

"I..." Gwen began to speak, her voice coarse and weary. "I guess that stronger climaxes are part of the spell or something." The tissue in her hand was utterly drenched with semen, if that stuff had gotten anywhere near your pussy, you would be in one hell of a situation! "Sure feels like it's much easier to have an orgasm, too. It's probably to encourage... uh... sexual activities." You nod along, her assumptions sound pretty spot on. Upon grabbing another tissue, she wipes off some of your own juices. "Just to be safe, I'll have a closer look at what our bodies, you know, expelled? To see if we're actually fertile or if it's all just some elaborate prank." With that done, she gathers her clothes and gets dressed again while you're still catching your breath, your tender vag on full display. An odd experience to be sure, but also kind of hot. Your room carried the potent scent of teenage pussy. Nice... !

"Make sure you don't get close to any guy while you're stuck in that body. I really don't want to keep having a dick, and you probably don't want to get pregnant considering you'd then be a girl forever." Just like that, Gwen returns to her room with the two samples of cum. Her mind was a whole lot more clear again now that she rubbed one out, and you smirked contently. The woman who put this curse on you sure messed up by involving Gwen in all this. At this rate, you probably won't even have to put any real effort into staying safe. She's actively helping you out, and in a little over a day, you'll be back to being a guy!

Over the next few hours, you have some fun downstairs by lazily spending most of the day in front of the TV in nothing more than your underwear and bra. Therefore it comes as surprise when you hear the door into the house unlocking, and see someone entering! Just a single person though, so you quickly assume it's not your parents... at least until your father steps into view.

He's even more surprised to see you, however. A nearly naked stranger sitting on his couch, in his house?

"Hello there, handsome," you say sweetly almost out of instinct, and you're quick to regret your choice of words! That was way too forward even by your standards. It did at least give him a good first impression, since he smiled back at you rather than kicking you out.

"Not an expected sight, but hello." You quickly get up to offer him a handshake, but he uses the chance to pull you in for a tight hug for a more... intimate greeting. You're about to push his hands off when you feel them wandering downwards, but get interrupted by Gwen who was swiftly rushing down the stairs and drew the attention of you and your father!

"Dad! Hi! Oh you already met her! This is... Sara!" Gwen's words came rushed, but were understood quite clearly. They probably would have even more of an impact if his hands weren't already groping your naked bum cheeks however, that stupid mini-thong didn't cover a whole lot of skin!

He smirks again and gives your rear end a good squeeze before allowing you to take a step back, apparently calling him 'handsome' made him very daring... "A fine lady. It's nice to meet you, Sara. A classmate of John I take it?"

"No, she's a friend of mine," Gwen interrupted. Things were much easier to explain that way. "But where's mom!? Weren't you two on vacation?"

"We were, but she had to leave for an emergency meeting, something job related. We'll have the house to ourselves for a while, and our new guest, I suppose." Though something tells you that he wasn't upset about your presence.

"Ah, I see. Well, Sara and me will prepare some dinner, I guess you will want to take care of the luggage and stuff first anyway," she offered kindly, though the anxiety in her voice was all too clear to you. After quickly ushering you out of the room and into the kitchen, she closed the door to give the two of you some more privacy. "Listen Sara- I mean, John... I had a look at the samples, and from what I can tell, our new genitals work as advertised. I produce sperm, and lots of it. You on the other hand are a prime example of a fertile mertile. I don't know what kind of advanced science or sorcery, is going on here... but you definitely need to be super careful. It probably doesn't take much to get you pregnant. You can't just go ahead and flirt with men, let alone our own dad!"

"Now hold on a minute!" You lean against the doorway and shoot her a glare. "HE put his hand on MY ass, that was none of my doing. I just happen to be hot. There's not much I can do about that."

"Uh-huh. Anyway, I don't want to have a dick, and in order to get rid of it, you need to keep your stuff in your pants until the time is over." Man, she's grumpy. You reluctantly nod along, and then help her preparing dinner.

A few hours pass, and you end up taking a warm, soothing bath towards the end of the day. You use the chance to explore your body a little further, soaping yourself up and caressing your skin. There was an inkling of pride in taking care of yourself and making sure that your skin remains flawless. Tenderly, your fingertips flow across your curves and slather the soap across, and you pay equally much attention to the fragile womanhood between your legs. After learning how soft and sensitive it is, you pay twice as much attention to that area. There was the faint temptation of slipping a finger inside your subtle slit, but after considering it, you decide against doing so. It's better to have nothing at all entering your cooch. The idea of having anything inside your body was just too weird.

You also grab a razor and neatly trace your crotch to ensure it's hairless, spotless and tidy! When you're done with your bath, you even apply some scented coconut lotion on yourself, and you feel like you're born again! It sure does feel nice to take good care of yourself.

Upon leaving the bathroom, Gwen pulls you into her bedroom while you're still only wrapped in a towel. "I gave this another thought! Since you're Sara now, we can't have you sleeping in your own room. That would raise way too many questions. Just spend the night here," she explains while pointing at a blanket on the ground.

Eh, could be worse. "Sure." It wasn't much, but again, you only had to endure this for another day and then everything will go back to normal.

After such an eventful day, you pretty much fall asleep as soon as you lie down...
