Big-titted married woman Riho Fujimori visits her brother-in-law's house with her husband in this intense production by Smartmedia Production / Delusion Tribe. The story takes a wild turn when her perverted husband forces her to entertain guests while wearing full-body vibrators. The aroused couple then dive into passionate sex that night, with Riho delivering an explosive, squirting orgasm that must be seen to be believed. Under her husband's command to go commando, she's left alone with her brother-in-law, leading to an accidental discovery of her masturbating in the living room. Later, dressed as a sexy sci-fi warrior character—possibly the seventh in a series—she's shaken and reluctantly pleasured against her will. Ultimately, overwhelmed by arousal toward her brother-in-law's cock, she abandons restraint and is taken by a man other than her husband, losing herself completely in forbidden pleasure.
