[Eno Yukimi] Teach Each Other (COMIC Anthurium 2019-03) [ConTL]

Mayumi Okada arrives at her former senpai's door in an off-shoulder sweater, all bright smiles and zero intentions of actually studying. Her nervous, glasses-wearing upperclassman barely gets a word in before she's peeling that sweater off and asking whether he'd rather have her mouth or her chest—then rewarding his honest answer by pressing those heavy breasts around him. When she presents herself and admits it's her first time, Mayumi takes the lead completely, riding him with the same eager confidence she brought to his doorstep, proving that teaching each other means something very different than either of them planned.
