Saki and her husband moved in with her brother-in-law's family for a month while their new apartment was being finished. Saki, who's normally energetic and has a strong libido, starts feeling increasingly frustrated as her desires build. Her husband refuses to have sex, saying it's awkward to do so at his brother's place. Living alone with her brother-in-law who works from home during the day, Saki can't hold back any longer and resorts to masturbation. But even that isn't enough. "Let's try each other's bodies," she says, throwing caution to the wind and giving in to her primal instincts, devouring her brother-in-law's cock in a forbidden, adulterous, and non-consensual sexual encounter!!!
