Losing my virginity in a threesome [FFM]

In High School, I took a guy to prom who I hardly knew. He went to another school, but my guy friend really wanted him to go so they could hang out. But when we got to prom, he was kind of a huge dick to me and only hung out with his friend.

Seeing I was alone and upset, one of my girl friends kept me company the whole time and would hardcore grind on me “as a joke.” She kept sliding my hands down over her pussy and would throw her head back on my neck really putting a show on for the guys at prom.
