[Hadairozanmai (Mitei)] Sensei! It's Time For Boobies [q91]

A group of busty schoolgirls descends on their hapless young teacher with one very specific lesson in mind, gleefully declaring "Sensei! It's time for boobies!" as they sandwich his stiff cock between their pillowy, oversized breasts. The girls trade off and double up, eagerly perfecting their titfuck technique while boasting about how much they've studied the art of the paizuri, pinching his sensitive tip between their soft mounds until he's utterly spent.
