As Sarah and Jessica grabbed Biff's arms, he felt a powerful tingling in his chest. As he stood up, he felt the weight of his breasts shifting on his chest. He wrapped his varsity jacket around himself to hide his endowments, and couldn't help but feel their soft weight as they pressed against his arms and body.
"Don't fucking touch me!" he said, although it came out as more of a shout. Biff turned and dashed down the hallway, away from the girls.
He had to slow down to a walk as his breasts started to bounce uncomfortably. He needed to find Karyn! As Biff rounded a corner, he crashed into Miss Mellis. It was a minor bump, and they both kept their balance, but Biff felt an all-too familiar tingling in his chest as his breasts grew another cup size.
"Oh, Biff, are you ready to write your test?" the pretty teacher asked.
Biff's heart sank. He didn't see much of a choice except to go with her. Biff told her he was ready, and followed her to the classroom. She sat him down, and Biff proceeded to fail the test horribly. It didn't help that Biff's knowledge of French was sketchy at best, but the biggest problem was that Miss Mellis kept touching him on the shoulder as she asked how he was doing. She touched him three times during the test, and each time his chest swelled even more.
Finally, he finished. Slouching as much as possible, he turned in his test, and headed for the door. Miss Mellis looked at him quizically and said, "Biff, is there something under your jacket?" but he pretended that he didn't hear her and headed out the door.
A few seconds later, Biff's football friend, Steve, grabbed his arm and said, "Hey, Biff, I wanted to talk to you about this morning..."
As the lightning shot from his arm to his groin, Biff decided that he couldn't stay at school for the rest of the day. Without responding to Steve, he ducked out the nearest exit and headed for home.
The need to masturbate rose steadily and frantically in Biff as he hopped in his car and peeled out of the parking lot. It took him about eight minutes to get home, so he thought he might have time to get there and jerk off before his ten minutes was up. He pulled up to his parents' house and ran to the door.
Biff searched his pockets frantically for almost a minute before he realized he had left his keys in the car. He ran back to the car, breasts bouncing painfully, and retrieved his keys so he could unlock the front door. He ran inside, locked the door behind himself, and bounced up the stairs to his room.
In his room, he pulled his pants off, frantically reaching for his miniscule nub of a penis. He tried to grab it to masturbate, hoping that he could save what little was left of it. Unfortunately, even rock-hard as it was, it was too small for him to grab with his fingers!
Biff licked his fingers and started rubbing his tiny dick, the same way he had seen girls masturbating in videos on the internet. Alas, he was too late. After a few seconds of rubbing, he felt a powerful, almost painful orgasm build, and then all feeling from his cock suddenly vanished. He looked down at his crotch, and saw a smooth, empty expanse with nothing but a tiny, nearly invisible hole where his penis used to be.
Tears started to tumble down his cheeks. Biff slowly pulled his jacket and t-shirt off, to survey the rest of the damage. He was shocked at what he saw.
His chest was dominated by two huge, firm breasts that stood out proudly from his body. It almost looked as though someone had cut a football in half and glued it under his pecs. He gingerly felt the strange objects. They were soft, and felt just like the natural breasts he had groped in the past, but they didn't seem to sag at all - they just bounced back into their perky position no matter how he squished, squeezed, or pulled on them.
Crying, Biff curled up in his bed and went to sleep. When his mother got home and called him for supper, he buried himself under the sheets and told her he was sick. He didn't come out of his room for the rest of the day, his mind racing to figure out how he could get Karyn to change him back.
