Caught in the Succubus Ranking and Cum Point Battle, a major event held in the demon world. Since last night, the succubus Mei Satsuki has been living in my room, and it seems she's targeting me for this annual competition. The rules are simple: succubi collect semen from men who've had no female contact and compete for points. They can even sense through telepathy when I'm erect. An elite succubus from another world relentlessly drains my sperm again and again with her expert techniques—an intense, shocking experience! [Celebrating KMP's 20th Anniversary!!]
