"Both of you, remove your panties and hand them to me. Leave your skirts up." They gasped but did it slowly. Belinda was a little slower to expose her...body to me but she did it. I went back to the SUV and retrieved a thin hand towel. I was holding their panties in my hand. I handed each sister's panties back to them. I said, "Now, Maddie, put your panties in Belinda's cunt." They gasped but obeyed. "Belinda, put yours in Maddie's cunt." Both girls were blushing furiously since they had to touch. Dinner over. I wait about 10 minutes then went to find this medical room. It looked the standard type of medical room with bottles of gas fastened to the walls and various cupboards. The doctor told me to sit at the desk as soon as I walked in. I noticed he didn’t look up from the fax he was studying but I put that down to him being busy. When he looked up he said,“Right Lady Charlotte, what seems to be the problem?“I just have aches and pains all over.”“Okay!”and he stood up put a thermometer. They were pulling their top legs forward to fully expose the other’s ass, and I thought it was so erotic how lustfully they were sucking, tonguing, and licking each other.After about fifteen minutes sucking one another’s assess, they moved back into position for her to suck his cock, and for him to suck her pussy. As we continued watching Benjamin and Wendy sucking one another, I felt a hand on my cock, and Russ leaning over towards me. He started stroking my cock, and said, “Just relax,. She put her head down on the floor with her ass up in the air and just purred and moaned in pure pleasure. Fidos dick remained lodged in her cunt and would stay there for at least the next ten minutes, the look on Amys face was that it could stay in there forever.While we were watching, Becky had come over and sat on my lap. The tiny girl fit perfectly into my crotch and I could feel the flange of the butt plug as she pressed her ass down on me. She took my right hand and put it under her skirt.
