So, I (24M) have a really hot cousin younger than me. She really mixed well with my family and we get along so well one can't distinguish if we're cousins or siblings or something else entirely. Last week she visited our home with her mom, and soon after both our moms went on chatting and catching up. They were busy cooking together and my dad had gone for his duties in the hospital. My younger brother was gone school, and so there were just me and her. We sat on my bed and had a long chat, and then one thing led to another and she confessed out of the blue, that she's always wanted to know how it would be like to be in bed with me. I was confused at first, but then I noticed her slipping her hand onto my thighs, and then we had a kiss. I told her to keep quiet as I got my hand under her shorts, starting to finger her pussy. She gave me an even harder time when she also took my dick in her hand under my pants. We almost got caught when my mom came, and said that they're leaving us alone in the house to go for some shopping together, and we agreed. After they were gone we just locked the main door and got started then and there, not wasting any time getting naked as we now had the whole house to ourselves. I even didn't know I could still get hard after five back to back rounds, and she was still insatiable as fuck. Till our moms returned, she had almost drained me, and the following night after everyone was asleep, we snuck out to the roof and had a few rounds there. Before she left with her mom the next day, she secretly bit my ear while we hugged, and then left with a wink.
