Michael had fucked her, He fucked Tanya, and at the moment he came inside her you wished "I Wish the wind would no longer violate Tanya, but instead only pleasure her every once in a while, much rarer than the wind flipping her skirt" This was his reward, his way of saving her from... part of the curse and you've had another delightfully devilish idea. "I Wish Tanya's bladder would shrink to 20% its size, and that Tanya could now only pee while masturbating."
Tanya felt a pressure, as suddenly it felt like her need to pee was at half of its limit, but she barely needed to pee but a moment earlier. This confused her, but maybe she was finally able to put on something... no she still felt the accursed wind, but it seemed much calmer now, she was tired, Michael was tired, they just had sex, and it wasn't even lunch time. what would she do now. there was really only option, considering, it didn't seem like her panties would be returned, or her skirt lengthen, or hell even the winds go away. She has sex in the morning, and it was 2nd period, so she had one thing to do. "lets clean up... I don't think its gone but it seems to have calmed down thanks to us... y'know" So she got herself cleaned in the changing room stall, the ever present wind went away in the stall as it was supposed to, but returned when she was no longer alone, she tried to pee... but something was stopping her.... she couldn't pee she needed to but her bladder wasn't responding "I-i think something wrong again...I can't- I can't pee!"
Micheal didn't know what to do this time, its not like his dick could fix her lack if being able to take a leak, all he could say was "What, think sex can fix that one too?" before being greeted with a swift "Pervert! That- That will only be the one time, okay!" They were both at a loss of actions. What would happen next?
