Hands-On Draining with Three Succubus Sisters

What do you get when a sex-deprived succubus meets the first man she can finally touch? A full contact, whole body, day-long banging session. The three Amaki sisters are untouchables at their school, and not just because of their perfect looks or standoffish personalities; anyone they touch immediately has an orgasm that will kill them if touched too long. While lamenting never being able to have a normal school life, Lamy, the middle sister, finally finds someone she can touch in her classmate Yuuki Subaru. And he's soon going to find out he can't keep her off him!
