Dr. Valentine wanted John to have big breasts

"Ever wondered what big breasts would feel like?" Dr. Valentine asked John and put both hands on his little bust.

"No?" John replied a little confused by the question.

"Some big, round breasts." She whispered into his ear while her hands skillfully caressed his two small mounds. "So beautiful both men and women want to get their hands on a pair of tits like yours. Just think about the sensitivity of them." She put both hands in John's bra and started to play with his nipples. "Playing with your tits would make you feel a pleasure that could drive you crazy." John let out a moan as his doctor kept playing with his hard nipples and the soft flesh around them.
