MGMQ-165 My best friend's girlfriend is a slutty woman who developed my anus while he was away and made me cum like a real man.

Taka and Ken are best friends. One day, Taka is invited to the apartment where Ken and his girlfriend, Natsuho, live together. Taka gets drunk and falls asleep, and when he wakes up, he finds Natsuho stomping on Ken's face under the bed! After leaving the room, Taka is curious about what the two are doing, so he peeks inside and witnesses them having reverse anal sex... And then Taka is invited back to their room again...
