Rika was kidnapped by someone and was forced to drink a special drug, which caused her body, which should have been a man's, to swell up to her chest and become a woman. Naturally, the training to turn her body and Kokoro into a woman's began. She screams as she orgasms over and over again as she is subjected to a series of tortures she has never experienced before. In the end, she cums in a daze, squirting juices from her clit-dick.
