Katie was onto her roommate.
He had been ogling her the whole afternoon, so in response, she had changed to a shirt that was a bit too large, and showed a lot of cleavage. He obviously noticed, and wasn't being very subtle looking. She couldn't stifle a giggle as he turned a deeper shade of red while blatantly staring down. To tease him some more she cupped her chest and pushed it up.
Without being too big, her breasts had a generous size, and lifting them up made them really stand out.
His eyes widened and his mouth was hanging open.
"Priceless," she thought as he was fixated by her boobs, apparently completely mesmerized.
She was liking the attention.
"Do you like my titties? You are really taking in the view, aren't you?" she said, jiggling them around in front of him.
The only response he managed to give was to nod dumbly, which only added to her mirth. She was going to have a bit of fun at his expense. Her feeling of control was exhilarating and accompanied by a pleasant light-headedness. She certainly wasn't going to stop now that she was enjoying herself so much.
This would have made her so embarrassed normally, she thought for a second. She would never have considered putting herself on display like this. But that was stupid. After all, it was ok to feel beautiful and to feel good. And she was certainly feeling sexy while he was staring at her.
A few weeks ago, she started watching a series of of videos on self-assurance. It was supposed to help her improve herself by working on her self image and her inhibitions. Her roommate was actually the one who mentioned the existence of those videos, and who shared the online drive where they were uploaded. They didn't really do anything for her, but the idea that it was ok to feel good and to feel sexy stuck with her for some reason.
Speaking of which, since he liked her boobs so much, she might as well drop any pretend modesty, and go all out.
In one swift move, she pulled up her shirt and her bra, exposing her breasts. They popped out in full view, swaying from the sudden release. She wiggled enticingly, shaking them around, to continue arousing him as much as she could. She got a thrill out of seeing how much it would turn him on. She was pushing her boundaries on decency pretty far, but right now it didn't bother her so much. She loved the idea of him getting a hardon watching her.
It also helped that her own switch had been flipped by the situation. She let her fingers trace around her nipples. They had become red and swollen, standing proudly upright on her chest. She couldn't resist pinching them a bit, to send satisfying waves coursing through her body.
