Mr. Oswald in first period was in an unusually good mood when the class arrived. He wrote for them a brief assignment on the board, and Jen thought she saw the briefest hint of Mr. Oswald wearing a thong, and then he sat down to let them work on it. He opened a book and pretended to enjoy it, but Jen was almost certain she heard the low rumble of a vibrator coming from below his desk, and noticed his legs were crossed in an awfully feminine fashion.
Most of the class didn't seem to notice Mr. Oswald, but a few did notice Jen's unusually large chest, just about as Jen did.
Morning announcements from the Principal were brief, but Jen did catch an odd mention of "the wonderful Mr. Oswald", but he wasn't paying attention to much more than his book, if he was even paying attention to that.
Given the opportunity Jen wrote down all the weird crotch swaps that had happened in the last two days and came up with the hypothesis it had something to do with her lies. She didn't quite no what was causing the chest swaps, but a quick bathroom break made her aware that she had Julie's C's with their puffy nipples and distinctive mole. She ended up having to quickly masturbate the large cock she had down below after her breast inspection left her erect.
When she got back to class she decided to test her hypothesis and take a more "long term" crotch. She debated keeping the meat between her legs, but was afraid of weird questions, and as much as she seemed to enjoy it as a small vacation she was getting bored with having the swinging between her legs.
She thought about it and then turned to Amy beside her, an uptight conservative and leader of the school's abstinence group, who had her hair in a tight bun that gave her the appearance and crow's feet of the school lunch ladies. "Your hair looks especially good today," Jen lied to her.
After a few minutes Jen gently probed her skirt and decided that she now had a pussy that was tighter than she had been even a few years ago. She wondered if the pussy had even seen much dry humping action, much less the sight of a dildo...
