My best friend's 19-year-old stepdaughter seeks my first sexual encounter

I've had a close relationship with my best friend for years, and his 19-year-old stepdaughter has always been like a sister to me. So, when she asked me to help her with some family stuff, I didn't hesitate. What she didn't tell me was that this would be our first time having sex. As soon as we were alone, she dropped her pants and revealed her delicious pussy, ready for action. She's a real hottie, with natural tits and a hairless, tight ass. After a steamy blowjob, I pounded her from behind, her moans echoing through the room. Then, she wanted to ride me, and as she bounced up and down, her clothes ripped off, revealing her natural beauty. Finally, I took her from the side, and with a few more thrusts, she reached her orgasm. Not bad for my first time with my best friend's stepdaughter, huh?.
