Unable to refuse her senior's lace-trimmed requests, she gets pleasure from his lace-knitting skills and becomes the submissive. (NHDTB-968)

After club activities, I witnessed a lesbian couple of upperclassmen courting each other!! I wanted to pretend I didn't see it, but they pressured me: "Let's judge whose technique is better!" I couldn't refuse, so I became their judge! They kissed, stimulated nipples, licked genitals, and engaged in a fierce competition!! I was initially just caught up in it, but I started to feel excited… The originally introverted and shy girl awakened her sexual desire and became the protagonist of the sexual encounter!
