She witnesses Ai masturbating in the classroom after school and gets turned on. She makes Ai masturbate and watches, pinching her erect nipples until they are hard and licking them with her skillful tongue. Her nipples are made slick with viscous saliva and stimulated, and she can't resist the naughty tongue technique and climaxes from her nipples. Mary then uses her long tongue to tease Ai's nipples, making her moan with pleasure at the sensation of the tongue. Her sensitive nipples twitch and spasm as they are sucked, and she finally climaxes from her nipples.
