When my partner is not around, I enjoy fantasizing about having sex with my stepbrother

I'm not around my boyfriend, so I like to fantasize about having sex with my stepbrother. It's a bit strange, I know, but it's the only way I can get off. I've always had a thing for older men, and my stepbrother definitely fits the bill. He's a hot European daddy with a big ass that I can't resist. When he's not around, I like to imagine him coming over and fucking me hard. I love the feeling of his big cock inside me, and the way he talks to me in dirty, filthy language. He's got a foot fetish too, and he loves to use his feet to tease me. It's a wild fantasy, but it's the only way I can get off when my boyfriend isn't around.
