Please do not judge me. But my girlfriends from college and I every few years take a trip together, girls only thing. We have a lot of fun. Nothing na...ghty, well most of the time we behave ourselves. But you know sometimes how the mood hits you. Me, Christy, Marge, and Tonya have known each other since high school. And now that we are in our mid fifties, married with family and all still get together to have some girl fun. Shopping, dancing and whatnot, girl stuff. We were driving thru Colorado. This was now down and dirty sex. I fucked Sarah’s ass hard and as fast. Exhaustion began to set in. I was breathing heavily and sweating. My arms and legs ached. I tried to control myself as Sarah moaned and made noises of pleasure, and grabbed at and clutched the blanket with her fingers. I plunge my manhood into her ass and whispered every dirty thought I could think of at that moment, in hopes of getting her to cum once more. “Fuck, you’re good. I love fucking your ass. You’re a great. As soon as I was satisfied that she was content and fully released I moved back up her quivering body, placing delicate kisses on her skin. I could feel her heart pounding in her chest as I kissed her deeply, letting her taste her own sweetness in my mouth. Her slick fluid on my face quickly smeared onto her face. Her scent filled the cabin. We both let out soft moans as our tongues danced once again. She pushed me back and immediately went straight for my pussy. She tossed up my skirt,. 'Mistress wouldn't let Her slave escape that easily! Stupid slave deserves to suffer for that.' I forced it to its feet and staggered back to Her crate, grabbing the bags of fluid. Simple enough: each had a single locking connector which matched one of the control boxes on the 'underwear'. Just three items now: the gag, the hood and the shoes. Clearly the hood had to go last, but doing the shoes would impede movement - the gag had to come next. With a little pain and pressure, the slave managed.
