[Nanbou Hitogakushiki (Nakamura Regura)] Rinraku no Susu me [SDTLs]

A voluptuous tutor with a beauty mark and enormous breasts believes the best lessons happen with her sweater pulled up, and her shy young student Aki never stood a chance once she decided to teach him everything firsthand. What starts as a nervous first blowjob spirals into drool-soaked deepthroating, cum-glazed paizuri, and a leg-locked nakadashi session that leaves the poor boy completely drained. Just as he's tangled beneath her blankets, the front door opens and his mother's voice calls his name from the stairs—forcing tutor and student to freeze mid-hidden-sex and pray she doesn't climb up.
