We were in Rob's truck, heading for his uncle's hunting cabin in the mountains. It wasn't hunting season, so it was a good time to go up there for a weekend just to enjoy nature. Of course, we brought Mary Rose and Theresa along because nature is so much more enjoyable when you are fucking in it. Mary Rose was in the cab of the pick-up with Rob while Theresa and I were in the back, which Rob had fitted with a big, comfortable, padded seating/storage unit under the cap. We had to share the space with all of the gear, but there was still plenty of room.
We started out talking back and forth through the little window but once the chatter died down, Theresa and I started making out. I slipped my hand up her shirt to fondle her round, full breasts and she accused me of getting her all worked up. While I was promising that I'd take care of her in whatever way she needed me to, we heard a groan. We both craned our necks toward the cab and could no longer see Mary Rose's head. We grinned at each other, then quietly moved toward the window and peeked through. Sure enough, Mary Rose had Rob's impressive cock out and was sliding her mouth up and down it while he was driving. I knew why Rob was groaning; Mary Rose was a skilled cocksucker. I based my opinion on personal experience.
Theresa was mesmerized and whispered to me about how hot it made her to watch. I whispered back, asking her how wet it was making her and how she would feel about getting fucked while watching. She responded that if I didn't stop talking about it and start doing it, she'd take care of it herself. She was on all-fours as she peeked through the window, so I moved down beside her and, after fondling her tits and feeling her hard nipples, I started to work her pants and panties down over her ass. While they were bunched up at her knees, I probed her pussy with my fingers, finding it overflowing with slick juices. My cock grew even harder as I thought about slipping it into her. While she continued to watch Mary Rose sucking Rob's cock, I worked her pants and panties all the way off and opened my own pants. I pulled out my rigid cock and rubbed it against Theresa's pussy before slipping easily into her.
Holding her by the hips and hunched over against the top of the cap, I slowly slid my cock in and out of Theresa's juicy pussy. This wasn't the first time I'd fucked her, but I was pleasantly surprised by how obviously turned-on she was watching Mary Rose blowing Rob. I leaned forward over Theresa's back as I fucked her, hoping maybe I could see some of the action, too, but all I could see was the back of Mary Rose's head bobbing up and down. Theresa was right up against the glass dividing the cab and the bed and taking everything in, including my rigid cock. I noticed that she was supporting herself with one hand while the other had snaked back between her legs. I could feel it occasionally on my shaft as she massaged her clit while I was fucking her.
I could see that Mary Rose's head was moving faster and, as it did, it seemed that Theresa's pussy got even wetter. Taking her by the hips again, I was fucking her harder, anticipating that she was close to cumming. Mary Rose finally raised her head but remained leaning over, still playing with Rob's softening tool after having swallowed his load. I think seeing Rob's tool fully exposed pushed Theresa over the edge and I could feel her shudder as her orgasm coursed through her. As Theresa came, she pulled me along with her and, before she finished cumming, I had exploded into her. I kept sliding in and out of her as long as I could, then pulled out and collapsed next to her. Theresa lay down and pulled her clothes back on while I tucked myself away. We kissed a little bit, then Theresa rolled over so that we could spoon and we were soon snoozing.
After a brief nap, we awoke before we got to the cabin. I don't know if Rob and Mary Rose were ever aware that we had both watched them and fucked during the trip. Once we were at the cabin and had unloaded our gear, Mary Rose decided that she was going to take a shower. The original bathtub in the hunting cabin, which was an old freestanding model on feet, had been retrofitted with a shower and the shower curtain hung around the entire tub from a continuous rod attached to the ceiling. After she'd been showering for a few minutes, I entered the bathroom to place some of my toiletries in there and to take a leak. While I stood there, I was thinking about how Mary Rose was naked behind the curtain just a few feet away from me and my dick began to harden. I got an idea and left my dick hanging out while I washed my hands. I stepped up to the curtain where the two sections overlapped and slipped my hard cock between them and into the shower.
Almost immediately, I felt a soapy hand sliding up and down my tool followed by warm water rinsing it clean. The shower then went off and I felt Mary Rose's talented mouth slide up and down my cock a few times. When she stopped, she opened the curtain, turned away from me and positioned her ass hanging over the rim of the tub. With the edge of this tub much higher than a more modern tub, her ass and pussy were at an ideal level for me to slip into her from behind. Taking my cock in hand, I rubbed it against her pussy, much as I had with Theresa in the back of the truck, then slipped into her. I took her by the hips and started fucking her, giving her my full length in somewhat rapid strokes. She was bracing herself against the far side of the tub with one hand while the other was between her legs, stroking her clit.
