When Maddi got everything settled in her locker, she decided to take a shower before going home, for a few reasons. First, she did kind of stink a bit, and second, she wanted to play around a bit before going home.
As she got undressed, she made sure to keep careful track of her bra and panties, so she wouldn't lose her friends. She did kinda like the power she had over them.
Before getting into the shower, she gave herself a look over in the mirror, and realized she was really getting turned on by all this. She had found out recently that she was bisexual, and had a slight fetish for breasts.
She quickly cleaned herself off, noting that it did take longer to get clean, as she was much more easily distracted with her second pair of breasts. She kinda felt sorry for the other two girls, as they were probably getting a bit lonely and bored.
After she was clean enough, she turned the water on to a much hotter setting, and got started with the fun part of her shower. She did kind of wish she had a second pair of hands, as having four breasts made it a little harder to get fully aroused. She managed well enough though, concentrating on the breasts that Joey had become, feeling both her own pleasure, and the pleasure Joey felt, which was significant.
As she reached orgasm, her Joey breasts suddenly started spurting, furthering her orgasm.
As she came down from her unexpected sexual high, she felt a sense of contentment from her Joey breasts. This caused her to grin slightly, as she had truly loved the experience, and hoped that Joey might want to remain with her.
She got dressed in a hurry, hoping that no one else was home.
