Prison School Vol. 7
Intended for mature audiences
While they might have been enemies, Kiyoshi and Mari need to work together like their lives depend on it - because they do! With snake venom coursing through Mari's body, the only way to save her is for Kiyoshi to get his lips between her thighs. But as they slither and writhe together, are they only falling further into the machinations of the Official Student Council?
