But I wasn’t done yet, and I had finally thought of the perfect thing to get revenge.I sat up, and got off her, “Get on your hands and knees.” S...e nodded weakly, sitting up herself before I slapped her face again, “I don’t have all day Isabella, move your fucking ass already!”There was a quick spring in her movements after that as I undid my belt and dropped my pants to reveal my rock hard dick. I saw her looking back at me, biting her bottom lip with her eyes screaming at me to fuck her. With. Robinson was starting to walk a little funny. Gabrielle had been a loyal assistant, running the experiments while watching me fuck Mrs. Robinson's lights out. Our initial round of testing complete, she was a logical (and very eager) choice for a second test subject.Gabrielle was a pleasing subject. She was a little on the skinny side, and didn't take care to do perfect trimming down there, but she had a nice rack hidden in her baggy clothes. The only issue was that she was a virgin, and despite. As soon as I do as I’m told Master slams back inside my pussy. Smacking my ass, one cheek and then the other. Alternating back and forth. Smacking and fucking me harder and harder. He pulls me up so my back is against His chest. I feel one hand close around my throat, squeezing a little bit and the other around my stomach holding me tight. Whispering how close He is to filling my pussy with cum. Small moans escape my mouth. ‘I’m going to cum my pet.’ He thrusts a few more times then holds me. She was glad Matt had called and talked to Marc. It would make talking to him easier."I'm fine, thanks. I'll be out of here in a minute or two. Are you sure Matt was okay with my staying here?"He was, totally. So relax. In fact, I told him that some of the club members and I were going out clubbing tonight, and he said he was hoping you would go along, since you have nothing else to do. He said it would sure beat sitting home alone. I didn't mention it to you earlier because I thought you would.
