IENE-934 — My Sister's Classmate Teases Me, A Virgin Who's Absent Due To A Cold, And Seduces Me With Her Panties

Suddenly, my sister's classmates came to my room. They were rummaging through porn magazines and stuff, but wait a minute! They were showing my underwear, not just my panties! When they saw that I got an erection, they didn't tease me, instead they made me confess that I was still a virgin, and their naughty pranks escalated...!? I was so lucky! It was the best experience of my first time!
