IENFA-8002 - A situation where one's younger sister is seductively dressed in a knit mini-dress and thigh-highs. Unable to resist the provocatively protruding buttocks, forceful insertion and repeated ejaculation occur. Aya Mitsuki.

Recently, a younger sister who has suddenly begun to feel feminine charm showed off a seductive knit mini-dress, conscious of attracting male attention. Excitement built from the exposed buttocks through the knit mini-dress, leading to an unbearable erection. Unable to resist, she was immediately inserted and ejaculated into from behind. Instead of resisting, the sister's sexual desire was ignited, and she began to actively seek a penis. Repeated forceful piston-like thrusts from behind resulted in multiple ejaculations.
