I think she is ok with it.” Lisa undid his pants and her hand found his cock, slowly stroking him until he was fully erect. He moved her to the bedr...om, took her pants and panties off, and bent her over the edge of the bed. He admired her ass as he reached between her legs to finger her. She was wet and ready and he wasted no time to push himself fully inside her. As he slowly moved in and out of her he said, “God, I love your pussy. I love to fuck you.” “Give me your cock. Give it to me!” He. Pulling back a little I thrust as hard as possible back into her ass. God she was tight and as I shoved in the shoved back against me. I do not think two wild b**sts could have behaved any different till I shoved one last time and exploded. I pumped me rectum full with my cum. My knees were weak and I held onto her hips just to stay on my knees. I fell back on the bed and she lay flat on the bed. Neither of us moved for some time as we tried to regain our breathing and let our pulse get back to. She pointed to three of the other guys in the office and me. “Right, you four can help us out. Get over to Meeting Room G3 and they’ll get you ready.”“I’m not really anything to do with the department,” I said, “I’m just here as a consultant.”She didn’t seem interested. “You’ve got a cock, haven’t you? Well, as far as I’m concerned that means you’re qualified.”I didn’t feel I had a choice. She didn’t look like she wanted to have a debate about it. Angie wasn’t around to appeal to and I was. Then I upped the incline, so she was jogging uphill for a bit before bringing it back down to flat for a short sprint. "Stop... stop, stop, stop, that's all I can take for today," She begged while puffing her guts out. So I slowed her to a trot for the cool down. "Don't worry," I said, "My first day after recovery was like that as well. You'll do better tomorrow." And so for the next two weeks, I trained my sister back into full, healthy fitness. Carefully sneaking peeks at her lustful figure.
