[Yamitsuki Gomakyu (Riku)] Downer OL Mesu Danshi, Erogari Zangyouchuu.

A dark‑haired office lady, Koyoi, discovers an unexpected homo‑turn that pulls her into a heated encounter with a curious, straight‑labeled young man in a cramped locker‑room. She removes her shirt and high‑heeled stockings, teasing him as she lets her clit‑dick and butt explode with cum, shouting that she’s cumming with her butt and urging him to watch. The playful yet intense erotic tension escalates to a climactic mutual climax, leaving both participants breathless and satisfied.
