Yoshinomi hates her mother's new partner to death. Her mother is away from home for three days, leaving her with a strained relationship. Just as the two of them begin to live a terrible life together, her father-in-law suddenly goes out of control. He laced his food with an aphrodisiac and raped his stepdaughter without her knowledge. Sweaty nighttime rape, squirting and toy training, and a sexy threesome with a stranger she found on a bulletin board... Eventually, Yoshinomi also wants the cock of the person she hated, and squirts out of her pussy, covering her 148cm minimum body with body fluids and going crazy over and over again!
