I seduce my promiscuous stepsister to disprove my supposed homosexuality

I've been labeled a homosexual by my friends, but I'm straight as an arrow. I've been trying to disprove this rumor for ages. My stepsister, a total slut, heard about it and offered to help me out. She's got a killer body and she knows how to use it. We got down to business, and she wasted no time getting on her knees. After a mind-blowing deepthroat session, she let me have a taste of her sweet pussy. She's a total vixen in bed, and I was hooked. We got into all kinds of positions, from doggy style to cowgirl. She even let me take her from behind, bareback. She's got the best ass I've ever seen, and I was drilling her hard. I gave her a hot load to remember, and she was begging for more. I'm finally free of that gay label, thanks to my seductive stepsister.
