The beautiful friend of my younger sister, alone with a big hard cock

My sister’s friend is a very beautiful girl with a big ass. I’ve known her since we were little, and she’d always come over to my house to play with my younger sister. Honestly, I never considered sleeping with her for obvious reasons, but recently she’s shown me that she’s not a kid anymore. I decided to give her a kiss and invite her to my new place to be alone, and I made her show me her beautiful ass, then I put my big dick in her pretty young woman’s mouth. When I was about to sleep with her, my dick suddenly went into her wet, narrow pussy. For that reason, I fucked her hard so that her ass would sound when it hit against my thighs.
