Karyn was dreaming.
She was sitting in the bleachers in the school Gym, watching some boys play a basketball game. This was unusual for her, but, dreaming, she simply accepted it. All of the boys had breasts of varying sizes, as one would expect if they were a random set of girls. She didn't know most of them, but found herself drawn in, not by the game itself but by watching their breasts move and bounce as they ran, stopped and occasionally jumped. She wished Jon were one of them. For a time she watched, and found herself following the bustiest player. Then she felt a prickling on the back of her neck and looked around, she spotted Sarah staring daggers at her and realized that she had been ogling Biff.
Then she was in a class. The boy sitting at the desk next to her was sitting with his chin resting on his hands, elbows on the desk, slightly hunched, he too had a decently large pair of breasts on his chest. She found herself lying her head down on her own desk, turned sideways, hoping to be able to look at the boy beside her without drawing attention. She could just see the curve of his breasts behind his arms, and under his slightly loose t-shirt, moving slightly as he breathed, changing which parts of his bust the shirt clung to as his chest expanded and contracted. He glanced over at her, she felt her breath catch, she had been caught!
She was sitting on the wall, Jon was jogging up to her, breasts bouncing, as he arrived she called out "Hey Jon-boyfriend!" and he embraced her and they kissed when he arrived. She could see past Jon's head, and behind were Sarah and Biff both staring with jealous faces at them. She knew Biff was jealous of Jon's bigger bust, and Sarah was jealous of hers. She continued kissing Jon. Then they were back in Jon's room on the bed, shirts off feeling each other up. Both of them moaning softly.
Then she woke up.
She was groggy and she could feel left over arousal from her dream. She tossed and turned for a while unable to relax, feeling pent up and horny. Soon she gave up on going right back to sleep and started playing with her boobs, imagining it was Jon, and that she was feeling him up, then she let one of her hand drift down and she started fingering herself, imaging that Jon was thrusting into her, he breasts dangling and swinging in time. Eventually she came.
As she lay there basking in the afterglow, she felt much more relaxed and thought about the dream. A version of reality where all men had boobs... what would that be like? It seemed very appealing to her right now.
She rolled over imagining what it would be like and drifted back off to sleep.
