“You need to get bathed and dressed.” I knew the voice and finally it hit me. It was Roberta, a graduate assistant I lusted for when I was in sch...ol. I remember reading that she was new to the faculty this year as a professor.“Hey Bobbie, good to see you again” I said with cocky laugh. She yanked the dog collar, pulled me toward her face and said, “Its Roberta, bitch. You’re mine tonight and you’ll be tasting cock before you ever taste any pussy.” Nikki and Nookie followed me into the suite’s. This little slut was coming out of her closet. She went from Ouch this hurts, to Fuck my little pussy.I got her doggy style and began fucking her but she did not like. I kept hitting her uterus I think and she almost cried when I went deep. That did not stop me from pulling her hair and finally putting my finger in her ass which she yelled and asked what I was doing.I told her we were going to do something different since her pussy was hurting from my NOT really big penis. I got some lube which. I stood up and put my flaccid cock away.“That was close. You better stay in here in a minute.” Dave said as he sorted his apron out. “Did you enjoy that?” I just nodded as Dave left.During the ten minutes it took for me to walk across the site back to work, I felt a range of emotions. I felt a bit dirty, ashamed almost, but also horny as fuck. I got into work and made sure things were running OK and that there were no messages before retiring to the toilet to finish what Dave had started. After. "You need not beg," he told her lovingly. "It may please you to consider yourself my servant, but to me you are my wife in all but name, and if it is your wish to bear my child, then it is my pleasure to help you meet that goal."I do ask you to consider one thing, however. The records we received from the aliens indicate that your Earthly body bore not just your own genes, but those of a sister that you never had. Instead of a child of our union, you could bear a clone of the sister you never.
