My fantasy

My step mother is lying naked in her bed masturbatingrbating I walk in and startle her. She sits up, and I see her tits and realized what she was doing. It makes me horny and my dick starts to get hard. She sees my dick getting hard and tell me, "We can't have you walking around like that all day, come over here." She is so hot, she is a BBW, with huge firm tits. She starts sucking my cock right there in her bedroom. She sucks my dick and i can feel my cock against the back of her throat, her lips on my ball sack, I almost cum but she stops, and tells me I can't yet, she wants to fuck me first. So she gets up on her hands and knees, and tells me to put my dick in and fuck her or she will tell my dad, so I do. I fuck her hard, I grab her hair at the base of her skull and pull with one hand and have the other one on her ass pulling my dick deep inside of her. We fuck for what feels like hours, doing every position we can think of. I bend her over the bed ,with both hands on her ass throwing my dick deep inside till she squirts all over me. I roll her over and she wraps her legs around my back, I suck and squeeze her tits while I fuck her so deep I bottom her out with ever thrust, she cums and squirts all over me. I tell her I'm gonna cum and she says to cum in her ass, which is soaked with her cum. So I pull out and fuck her in her ass hole while I squeeze her tits, filling her ass with my hot cum. she wispers it will be our little secret.
