Succubus Family – The Semen-Draining Contract and the Boy Who Was Taken In

Succubus Family – The Semen-Draining Contract and the Boy Who Was Taken In is an RPG-style adult visual novel for players who want a monster-girl harem story with a submissive male lead. The tone is playful but leans hard into domination and teasing.

Story

After losing his parents without warning, the protagonist is taken in by Yuri, a neighbor he has admired for years. Her household turns out to be a family of succubi who survive by draining semen from human partners, and joining them means agreeing to a contract whose terms are far lewder than he expected.

Gameplay

Play centers on managing daily life inside the succubus household, moving between the women of the family as their contract terms and demands unfold. Encounters are presented through 2D animated scenes with voiced audio, framed as an RPG-simulation loop of exploring the house, talking to its residents, and responding to their advances.

Features

• Animated 2D scenes with voice acting throughout
• A household of distinct succubus family members, including older and dominant character types
• Femdom-driven encounters framed around a recurring "contract" mechanic
