Roleplaying with my stepmom's big butt in doggy style

I've always been into some wild roleplay, and my stepmom is no exception. She's got a big, juicy ass that's just begging to be spanked, and I'm more than willing to oblige. But that's not all she's got going for her. She's also got some killer natural tits that are just as tempting as her round, bouncy butt. When we're alone in the house, we like to engage in some steamy doggystyle action, with her bent over and me pounding her from behind. It's a sight to behold, her blonde hair flowing down her back as I slam into her, her moans echoing through the empty rooms. It's not just about the sex, though. It's about the thrill of the forbidden, the excitement of being her naughty son, even though I'm not really her son. It's a hot, sweaty, dirty fucking session that leaves us both breathless and satisfied.
