Mike said he was going for a beer but would be back early.In the room where I given my ass to a man and taken his penis into my mouth, I was restless ...nd nervous. I stripped all of my clothes off and lay on the bed, waiting for Mike to come back in and take me again. My cock stayed semi-erect and I was tempted to masturbate, I was so turned on replaying the previous night's events, but I didn't want to waste any sexual energy in case things happened again. I lay on my back with my legs. It took a couple of minutes for either of us to gain enough strength to do anything and that was just for me to say, aloud this time, that this was going to be a wonderful day. With that being said both of us broke out in a fit of laughter that neither of us could control. After about a half an hour of resting in the same position with the only change being me moving one arm to place a finger into her warm wet pussy and slowly move it in and out. She hopped up from the bed and ran to the other. She was perfectly friendly to me, and I did not have a chance to talk to her about anything but the assignment, so I guessed that everything was OK until I heard something different.This was going to be an entirely different run from that first one. This time we were going to a recently discovered planet that had once had a sentient population, but was now unoccupied. We were to do a preliminary survey to see if we could spot the reason the planet was now deserted. Just to be on the safe side,. There was a big dressing table in front of the bed and I can see her big ass going up and down and touching my thighs. I liked her big ass and I was slapping that ass as she was riding on me and moaning like a mature bitch. I was holding her boobs and stroking her as she was jumping up and down on my cock.Than I slowed down and made her turn around and now her fat ass was facing me and she was facing my toes and again she ride and this time we went crazy as this position was more penetrating..
