All the chatter in the locker room died down when the PE teacher came out of her office. Jonchelle immediately recognized her as Coach Barnett, who had undergone a transformation of her own. She still looked quite fit, but it was clear she’d added some breasts and a new outfit.
“Hi class,” she said in a voice that she was clearly trying to nudge higher. “Hope you had a good break?”
The girls all nodded.
“I know, it’s been a fun adjustment so far, but I think it might be worth our time to figure out how our bodies feel after the holidays and everything else, so today we’re only going to do some light aerobic exercises. Let’s head on in.” The group of girls walked down the locker room hallway and into the gymnasium. “We’re gonna start with a few laps around the court, nothing too difficult.” Everyone lined up and began easily doing laps around.
“Wow, that’s more movement than I expected,” Jonchelle heard one girl say behind her.
“Boobs?” another called out.
“Yeah.”
“Coach Hampton said I’d have to get used to that,” Coach Barnett quipped, referring to who had been the girls’ gym teacher. “He said that they had to be careful with their binders too, because you can’t wear them for too long a stretch.”
Vanessa giggled in her head, thinking of how advice she’d heard being given to trans men was now applying to cis folks.
“Jonchelle must be really feeling it!” another girl called out as she turned a corner. “She’s got big ones.”
“Now I get how my old girlfriend felt after exercising,” another thought out loud. Vanessa nodded, having managed to catch up with Jonchelle.
“I know what she means,” she whispered. “These are unlike any breast forms that I’ve tried before. It actually feels like I have breasts.”
Jonchelle nodded. It was weird: the breast forms actually had weight to them, and she could feel every bounce as she ran. If she didn’t know any better, Jonchelle would say that she actually had breasts.
Coach Barnett, meanwhile, had been looking at her watch; after a few more minutes, she had decided that they had had enough, so she blew her whistle.
“Okay, girls! That’s enough for today. Let’s get changed.” The girls stopped running and turned towards the locker room.
“Man, I feel really tired.” one of the girls commented. A couple of others agreed, while others complained of feeling a little bloated. One by one, the girls took off their gym outfits and prepared to return to their street clothes (and school) when, suddenly, one of them screamed.
“What is it?” one of the other girls, Shawna, asked as she ran over, concerned. The girl who screamed stood there in shock, pointing to her panties and sobbing a little. Shawna looked at the panties, which had dropped to the floor, and then picked them up gingerly, showing them to the others.
Blood.
“Oh my God!” Vanessa gasped as she realized what that meant. “You’re...on your period,” She explained. Everyone turned and looked at her.
“What!? How is that possible?” One girl asked. Vanessa saw jaws starting to drop.
“Yeah, only girls get periods...” another pointed out.
“Well, if you think about it, we’re all girls now.” Vanessa said pointedly. “There must be something, like the breast forms, that are transferring the experience of having a period to us.”
Jonchelle’s eyes went wide. Maybe Karyn was right after all. This had to be wish-induced. There was no way that boys could have periods otherwise.
“Hey, mine are all bloody as well,” Amy exclaimed as she took off her own panties. Everybody panicked and checked their own, sure enough, everybody had a spot of blood on their panties.
“Hmm, interesting.” Vanessa muttered. “It looks like we’re all on the same cycle.” She giggled a little at the thought—every girl in school on the same cycle.
To confirm her suspicions, Coach Barnett burst into the locker room looking concerned.
“Is everyone alright?” she asked, a hint of confusion in her voice.
“We’ve got periods!” one girl told her bluntly, looking on the verge of tears. Coach Barnett sighed, a look of knowing on her face.
“It’s...as I suspected, then,” she began, pointing to her own torso. A girl at the back slowly raised her hand.
“Yes, Adrianna?”
“Does this mean that we’ll get pregnant?”
