A beautiful and sexy female teacher loves to develop men's nipples. She gets even more excited when she sees the face of a man who feels pleasure from playing with her nipples. She licks them with the tip of her tongue, kneads them with her fingers wrapped in saliva, pinches and scratches them... She never lets go of their nipples, even when she's giving them a blowjob or inserting them. Because she loves to play with nipples (heart), the always-on-the-ball "female teacher Tsumugi Akari" finally becomes a slut!!
