Staying at her sister's place, she gets caught masturbating after watching the couple. The next day, the brother-in-law strikes while the wife is away, and her sex-starved body can't resist his raw power.










Since it was originally just a way to vent from a sexless life through 'fan activities,' it was fun to watch her reach such a peak. I'm sure the memory of idol concerts was long gone by then.
Tsubasa-san has a truly artistic butt. The black pantyhose wrapping around it just doubles the eroticism.
Early in the story, Tsubasa-san peeks at her sister and brother-in-law's intimacy, gets turned on, can't sleep, and starts masturbating. What's great about this actress is how her body twitches when she touches her nipples, and how she aggressively fingers herself to climax without needing any toys. Watching her spasm while finishing was amazing. The camerawork was also great. She gets caught by her brother-in-law and has two semi-forced encounters, but the most erotic part was definitely the solo masturbation scene.
