Great idea i thought as i had just done 4 hours solid exerciseI found the bathroom along the landing and soon worked it out , i stripped the last of m...y clothes off and climbed under the hot waterI turned to see Demi watching me shower until she spotted my knickers on the floor and she quickly picked them up and buried her face in them, i thought she was going to cum again with the sounds she made, then she told me she was keeping my wet used knickersShe placed them in a cabinet and climbed into. I reached in front of her and started massaging her clit. She started humping faster and soon we both started cumming.From that day anal sex became routine. I even bought a vibrator dildo so that I could fill both her holes at the same time.I started thinking of giving her a group sex experience, but I had to be careful who I chose so that no one else on the farm got to know. I had made a good friend named Mike. He lived and taught at a nearby boarding school. He was a young bachelor aged about. Tom kept twitching, and I wondered, vaguely, if he was still coming (you can't always tell if a guy is coming if he's inside you). Finally he stopped moving, and the two of us just lay there, breathing hard.Whatever urges I'd had before the party seemed to be satisfied. It was still early in the afternoon, and yet I'd had some of the best sex ever, and come so hard I'd practically passed out. Oh, I'd go again after some rest, but for right now I just wanted to sort of drift and relax.I wasn't. I tried playing with his balls, which he loved, he gasped at my touch and yelped like a puppy. I was amused by his reaction, but it felt weird, so I stuck with just playing with his cock.Still stroking, I looked into his eyes, “Are you ready?” I asked. He groaned in ecstasy and nodded his head; I stood up and pushed him back onto Reagan’s bed. I hiked my skirt and straddled him, knowing that by sitting on top of him I’d be able to get off pretty quickly if someone walked in. I didn’t stop to.
