Story :  "You're not dirty, Matsumoto." He was licking the sweats that dripped from my breasts with his tongue while looking at me... My body went numb and jerked involuntarily. I shouldn't feel it more! Nanami Matsumoto decided to go on a diet after her boyfriend called her "heavy." She asked Onozaki, an instructor and an old friend she met at the class reunion, to be her diet coach. "It may hurt, but please bear with me." Onozaki started to massage her after saying that. But then, he put his fingers inside her...!? He was rubbing her sensitive pussy, she couldn't hold her moans...! The floor got wet with sweat and love juice. Onozaki was earnest, but why would he go that far...?
