My step-sister gave me her curvy butt for my birthday

I've always been a fan of curvy Asian babes, and my step-sister is one of the best. She's got a killer body, with big tits and an ass that won't quit. So, when my birthday rolled around, I knew exactly what I wanted as a gift - her tight, round ass. I wasted no time in getting her to bend over and presenting her with my throbbing member. She took it in like a champ, her tight hole accommodating me perfectly. After a mind-blowing blowjob, she let me take her from behind, her ass bouncing with each thrust. The sight of her fat ass clenching around me was too much to resist, and I couldn't hold back. I filled her up with my cum, leaving her satisfied and ready for more. It was the best birthday gift I could ask for, and I hope she knows I'm forever grateful.
