A big-breasted married woman, A-san, who is half serious and half teasing a boy who has a crush on her at a class reunion, shows off her panties to seduce him. She can't control herself when she sees him taking off his panties in the hallway after spilling beer on her! When she goes to the bathroom with her girlfriend, she grabs his erect penis and we can't stop panting. She stuffs her mouth full of the curved erect penis of a man who has transformed from a herbivore to a carnivore, and gets even more excited when she sees her face in the mirror with it inserted deep into her slimy pussy! She is found by a classmate while they are having sex in the bathroom, so they change places and cum in various positions that they couldn't do in their married life!
