After enjoying our last day at the hot springs, and getting an amazing blowjob from my stepmom, we were getting ready for bed back at our rental when she came out of her room suggesting that i come in and 'cuddle' with her like we used to. I responded 'yes' without hesitation, and headed right in there with her. I sat on the bed and she immediately started stripping out of her dress, explaining that she lounges in the nude and coyly asking me if i lounge in the nude as well. Regardless, i agreed as she pulled off my pajama pants, coming straight for my cock with her talented mouth. But she didn't stop there. I was thinking 'yes my plan is working!' as she climbed up to mount my throbbing cock with her already-wet pussy! Feeling and watching her ride with her tits bouncing and then her ass after she turned around to ride me reverse. By then I was so worked up; i needed to have my way with her, all the way, so i laid her ass back to fuck the hell out of her and make her cum even more on my cock, until i felt my second load of the day welling up, ready to shower her bush with my gooey tribute to her hotness....She told me after that I now belong to her and thats great because thats exactly where I want to be; Stepmommy's Boyfriend!
