MOPP-119 Himari Aizuki, a cocky little girl childhood friend, sees through my blatant masochistic tendencies and teaches me a lesson with reverse anal sex.

My childhood friend, Himari, has a mischievous personality and used to always make fun of me when we were kids because I was older and shy. While I was annoyed by her, I also had feelings for her during my adolescence, and I would secretly fantasize about her while masturbating. Several years later, I'm a university student living alone. One day, Himari suddenly shows up at my unremarkable apartment! She teases me like we did as kids, and when I try to fight back, she pushes me down instead...! As if she saw through my masochistic tendencies, she straddles me, plays with my sensitive nipples, and even goes for my anus! I'm toyed with by this younger, more experienced little devil, and I'm overwhelmed by the pleasure of defeat!
