[Hidarimigi (Nitouhen)] Futanari Succubus ni Rettoushu to Wakarasaremashita -Zako Mesu Soshitsu Ariari Omanko Onii-san Mikke!- [Anamio Animus]

A curvy futanari succubus with horns, wings, and a wicked grin corners an ordinary guy and introduces herself as a sex demon before pinning him down to milk his prostate, cooing that playing with it is like unlimited energy refills while he cums helplessly under her. She rides him cowgirl, teasing him about climaxing like a girl as her own thick shaft bounces between her toned abs, until he's left gasping that he's about to die under her relentless pace. By the end, he's been thoroughly broken into a masochist who cums while being choked by the sadistic younger demon, and a dark-haired girl watching from the shadows seems to have awakened to her own cruel streak.
