[Kise Itsuki] Makeruna Zetsurin Sensei! (G-Edge Vol. 014) [SquigglesJP]

A braided schoolgirl has her hapless homeroom teacher exactly where she wants him — blackmailed into bed with his career on the line and his 'consent' freshly extracted. Between rounds she holds up the spent condom to mock his shabby stamina, teases him to train more before trying again, her plaid skirt hiked up and a choker snug at her throat while he sweats through every round. When the rubber supply finally runs dry and she breathes 'do it,' the exhausted teacher discovers just how bottomless his student's appetite really is.
