[MFK-0104] Sisterly Devotion. The Campsite Owner's Sex Slave Prison (Chinese AV)

A campsite owner's twisted prison where two sisters are captured and turned into exclusive sex toys. They're subjected to daily rounds of training, with rough penetration, mutual oral pleasure, breast clamps, and a red, swollen buttocks. Their throats and vaginas are filled with semen. The campsite is a hellish nightmare, with the sisters crying out in pain but unable to stop their climax. They beg for mercy but instead, they open their legs willingly, succumbing to extreme SM training that will leave you breathless and satisfied.
