So me (male 19 and my cousin (female 18) we’re both living at my grandparents, and one night we were messing around like we usually do (like taking each others phones and stuff). Well there was a few times that we ended up rubbing against each other, then that turned into touching, then that turned into us 69’ing.

Then a few months later, we’re messing around again, then she comes over to my bed to grab her phone, and completely straddles me, well that made me probably the hardest I have ever been. She could definitely feel it through my pants, so she started moving back and forth, so I pulled her pants down, and she pulled mine down, and we had the best sex I have had till this day
