[Kimidori (Kasane Haruo)] Kyouiku (Sumi) {Chin²}

Young Ryou's so-called education reaches its final exam as a circle of towering, muscle-bound men pin his sweat-slick little body between them and claim his tight hole one after another, each thick cock cramming deeper than the last. His tutors work with patient, methodical intensity — coaching him to breathe slow, to loosen up, pushing in little by little — because they have no intention of breaking their eager student before they've wrung every last shudder from him. With Ryou left a trembling, dripping mess and murmurs of how much more his body can still endure, the men settle in for a long night and the lesson is only just getting started.
