Young and horny step sister gets help from her step brother

I've got this hot 18-year-old step sister who's always up for some action. She's a total looker, with a body to die for and an insatiable desire for sex. One day, she came to me, all horny and ready for some action. Being the good guy that I am, I decided to help her out. I started off by teasing her sexy ass, kissing and fondling it, before plunging my hard cock deep inside. She loved every moment of it, moaning and writhing in ecstasy as I fucked her tight little ass. The sight of her getting pounded was too much for me, and I soon blew my load right inside her. A truly unforgettable experience, and I'm sure she'll be back for more soon.
