Accept, otherwise she may still doubt you

Crap, crap! This wasn't at all going according to plan. All you wanted was to have a brief introduction and then go back to hiding in Jimmy's bedroom until the curse wears off. If you stop playing along however, you seriously risk getting kicked out for good - or worse, having your parents discover that you're John and then doing god knows what. No, you only need to get by for another day or two and everything will be right again.

After hesitating for a moment, you reach for the pill with a badly faked smile on your face and swallow it down. You've already taken one earlier anyway, a second one may not even do more than the first one did. "Datta girl!" your mother says cheerfully while you feel the capsule sliding down your throat. There's no going back now.

But... nothing happened. In fact, even your mother simply returned her attention to the TV, while Jimmy was still slightly out of breath and doing the same, his flaccid appendage still glistening with your combined juices. Considering you had nothing else to do in this temporary body, you sighed and simply joined in - staring at the TV and embracing your nudity. It's not like you could put on some clothes after the stupid lies from earlier, nor could you go to school or visit friends - that would just raise even more questions.

Hours pass, uneventfully. In the evening, your mother prepares dinner as usual, and you're presented with a decent family dinner and even Gwen joined in. It didn't even take much explaining, she didn't question who you are after being introduced as your brother's girlfriend, nor ask why you're a nudist. It was just like any other day, and you briefly even forget that you are a girl while everyone was eating so... peacefully. You do take a quick shower afterwards, and make sure to clean your slightly tender vag from any and all traces of sperm. You wash every inch of your body - outside and inside, to minimize the odds of getting preggers. The last thing this world needs was another Jimmy growing in your belly. One of them was enough.

Around bedtime, you even make the mistake of walking towards your own bedroom rather than Jimmy's, only to have your mother smirking and pointing you into the right direction. Aw well. After brushing your teeth, you join Jimmy in his room and upon closing the door you give him a long speech in private about how you don't want to have any more sex, and that you simply can't risk getting pregnant. Oddly enough, he accepts immediately and without complaint.

A few hours earlier

Jimmy stood by the kitchen sink, helping his mother with the cleaning while looking clearly unhappy with the recent turn of events. After all, he had just gotten a girlfriend! ... yet didn't get nearly as much sex as he had hoped. Virginity gone or not, getting laid was awesome, shame he wasn't getting more of it. His mother noticed his mood, and poked his side with a concerned expression. "What's wrong, dear?"

"It's Sarah. I was hoping we would get to have a bit more... you know... naughty times? Especially after those weird pills you gave her." He grabbed another plate, washed it and handed it over to his mother to wipe it dry.

"Oh those? They can take a day to reach their full effect. Just ask her again tomorrow and she'll probably not even hesitate."
