Virgin's First Popped Knot

Shinsou goes to Aizawa to learn how mating really works. Aizawa and Hizashi give him a live demonstration. Hitoshi however hasn't ever had a knot and he hasn't ever popped a knot before and this is his first time with a heating omega. Thankfully Shota and 'Zashi are very good teachers. (No student x teacher. No underaged.)
