Who would have thought that my sister-in-law would be working at a big-breasted body-washing beauty salon? Hinata is shocked by her brother's unexpected appearance. She tries to persuade him to refuse, but he refuses because he's already paid. Hinata gives up and makes him wear paper panties, and starts the treatment. Her whipped penis is so good that it won't go down, so she pulls it out and gives him a handjob. He almost ejaculates because of her lewd touch, but she stops just before it happens. She uses her big breasts to give him a close-up titjob, stroking his dick. The brother wants to have sex, so he rubs his big breasts and seduces him. Perhaps because of his brother's foreplay, Hinata starts to feel sensitive. She straddles her brother and inserts herself in the cowgirl position. She climaxes while moaning as her pussy is penetrated in positions such as the cowgirl position, reverse cowgirl position, doggy style, and missionary position. Seeing his sister (Hinata) in a state of shock after having a huge amount of semen ejaculated inside her, the brother-in-law must have realized that this was not good and quickly retreated.
