[NHDTB-968] A plain girl with glasses can't refuse the request of a senior lesbian couple and is played to judge whose lesbian technique feels better. (Censored)

After club activities, I witnessed a lesbian couple's courtship scene! I tried to pretend I didn't see it, but they pressed me and said, "Judge who has the technique!" I couldn't refuse and had to judge their lesbian technique! Kissing, nipple play, cunnilingus... a heated development in which neither of them would give in! I thought I was involved, but I ended up feeling it... A plain and quiet girl awakens to a female orgasm!
