The son's friend, Hiroki, has photography as a hobby. Tsugumi happened to be there and became his model... She noticed him staring at her chest, so she teasingly showed it off to him. Unable to bear it, he bulged in the crotch area, but she approached him casually... However, no matter how many times they did it, his momentum didn't stop, and he kept raping her over and over. And every day, as she continued to be raped, Tsugumi's body and mind became too sensitive, finally letting out a scream.
