Erika almost immediately felt a hot wave in her chest as the spray soaked in, leaving her chest feeling itchy. She quickly slipped off her shirt and went to her mirror to see what was wrong. As she scratched her fingers bumpes against her nipples from time to time, sending waves of pleasure through her. By the time she reached the mirror she was simply tweaking them back and forth.
Her chest was growing quickly now. Erika had been an A cup before but she was quickly reaching a CC. "What's happening to me!?" Erika cried out as her hands kept tweking her growing nipples. Seconds past by as her chest bulged more, forcing Erika to lean to hold the weight. She could feel her back strengthen as she felt herself now able to support the massive yoga balls attached to her chest. Her nipples had sprung out to be four inches while erect and begged for attention though Erika couldn't reach them. Her pants were soaked through from her excited sex.
Erika examined herself in the mirror, happy with what she saw. She was always so jealous of the older girls with huge chests, now they would all be babies compared to her!
