My classmate comes to "study" and I end up riding his HUGE cock until he cums on my tits

I invited over my classmate to study maths at my home when I was alone because my parents went on a trip for the weekend... and I was feeling really horny before he came, so much I even wanted to masturbate but then he knocked at my door and I opened it and started provoking him until I took hid dick out of his pants and shoved it inside my pussy soooo good...
