Jon stopped by the boys' bathroom on his way to English. After checking that there was nobody else in the bathroom Jon removed his shirt to see if he could find any changes to his body. He couldn't see any changes but the skin of his upper chest felt to his fingers extremely tight like an over inflated basketball.
His nipples looked a little puffier and when he brushed one with a finger it shot a jolt of pleasurable sensation straight to his groin. He immediately felt an erection growing in his pants.
A quick glance at his watch told Jon that he had about 10 minutes before his next class began. Slipping into a stall and locking the door Jon dropped his pants. With one hand stroking a nipple and the other his penis Jon began masturbating furiously.
Jon was stroking so quickly and with such long strokes that he didn't even notice the couple of times that his hand slipped off the end of his penis. With the added pleasure from his newly sensitive nipple Jon finished in record time letting his cum splash into the water of the toilet.
Jon sat on the toilet for a couple of minutes just trying to catch his breath. He'd never masturbated at school and he was a little scared that he'd been driven to do so just by simply touching one of his nipples.
Realizing that if he didn't hurry he'd be late for class Jon pulled up his pants, flushed the toilet, and washed his hands in a rush.
English class consisted of reviewing the latest chapter of "Sophie's Choice" that the class was supposed to have read the night before. Jon had been too busy worrying about what he'd done to Karyn and how she was making him work to regain her trust and friendship. Jon was lucky that the teacher never called on him during the discussion.
Jon relaxed a little during his Art class. He dove back into the painting that he'd started before spring break. The simple act of putting paint to canvas distracted him from his current situation better than anything else had to this point.
All too soon it was time for Jon's last class of the day. They were studying the Battle of Hastings and the conflicts afterward which Jon thought it was all fairly interesting but he found it hard to concentration because it felt like the skin of his chest was being ripped apart from the inside. The pain was nearing an unbearable level as the final bell of the day released the students from their educational imprisonment.
Stumbling from the pain Jon made his way back to the boys' bathroom. Jon didn't even have to remove his shirt to see the swelling of his upper chest. The pain slowly began to lessen as Jon removed his shirt. His nascent breasts were a bright red color like he spent a full day laying on the beach without sunscreen. The pain almost gone but touching the newly stretched skin brought it back. The skin was radiating heat that Jon could feel even holding his hand an inch from his chest.
Jon decided he would wait in the bathroom until the pain was entirely gone before even trying to put his shirt back on. He leaned against the counter settling in for the wait when suddenly the bathroom door opened and somebody walked in spotting him immediately.
