Jeff watched the other girls leave the showers and was about to follow when she felt the first tingle in her breasts.
Jeff walked out onto the deck, her breasts already reaching a C-cup and dived into the pool. By the time she got to the other side of the pool her breasts had reached a DDD-cup and her wet swimsuit was stretched to the point that it was quit thin, so much so that it was almost transparent.
As she was getting out of the pool she heard one of the other girls say to her friend "I bet the cow is going to rip her suit open today."
