The Evil of Commons

In the infirmary of an abandoned school that is often the subject of horror story rumors----
There exists the "Commons," an entrance to another world where succubi lurk.
A boy enters out of curiosity... and becomes enthralled to and toyed with by a succubus.

While he may be inexperienced, his libido is bottomless.
The succubus uses her demonic abilities to amplify his carnal desires, and the boy loses all sense of reason... his ejaculations like a ticking time bomb over which he has no control.
Handjob, fellatio, titjob, cowgirl style, missionary and more! He will pathetically cry and moan in the throes of overwhelming pleasure while the succubus makes him cum over and over and over again.
