Suddenly, my sister's classmates barged into my room. They're rummaging through my stuff and giggling, but wait a minute! It's not just a panty flash, I can see too much of their underwear...! Seeing me get an erection, they didn't just tease me, they forced me to confess that I'm a virgin, and the naughty pranks escalated...!? Super lucky! It turned out to be the best deflowering ever!
