[Koyumean (Kazakami Sudare)] Kakedashi Yuusha ga Onee-san Succubus no Milk Server ni Naru Hanashi

A rookie hero picks up a low-difficulty subjugation quest after reports of a devil-winged beast with an enormous tail haunting the beginner forest—only to find his quarry is a voluptuous succubus with far more than battle on her mind. Snared in her massive prehensile tail, the hapless adventurer is straddled and ridden at merciless speed while she purrs for him to become an idiot who can only think about cumming, milking him dry like a living sperm server to fill her wine glass. Relentless femdom, brain-melting climax after brain-melting climax, and one very hungry tail turn a simple monster hunt into a one-sided feeding the young hero never stood a chance of escaping.
