"All I'm saying is, you don't have to have se...x with me, unless you really want to."Ursula crawled forward between my legs. "But we like having sex with you." She popped my limp cock into her mouth.Uma, climbing on the bed, finished her partners thought. "It's fun. And we challenge ourselves each time. We see how many times we can you hard, how quickly we can make you come, or how long we can. This went on for 5-10 mins and then Alex and Monica got up. Alex removed her panties all the way and removed her top too. Now, all three of them were stark naked. Alex and Monica were standing just in front of the sofa facing Joe who was sitting on the couch. Alex just lifted her left leg up till his hips and asked her to lower her front part towards Joe.Alex now inserted her from the back in standing position. Joe stood up and made sure his penis reaches Monica’s mouth. At this point, it was. This originally was Anna’s idea she wanted Jim and some of his friends to come over and fuck her until the sun came up. Jim knew the right kind of guys that would be down to fucked Anna, fill her with come and could go all night. The deal was that on Friday night Anna and I would be home, Jim would show up with all his friends and the party would begin. Anna was excited and so she started that afternoon getting ready make sure to pamper herself appropriately for all the men she was about to. So after that night nothing happened I didn't even talk to her for a couple weeks. Then my wife called saying they had a tree blow down in the storm we'd had earlier in the week. If I would want to go cut it up for firewood. I told her I would but it'd be a couple days. Well I finally got a break so I rode on over with my saw one afternoon. Damn it was a huge tree . So I would cut a lil while then split some then stack it for easier loading. I was getting hot finally I seen her walking.
