I hadn’t cum yet, but it felt so fucking good to feel Robbie’s warm, thick cum fill my insides and then feel it slowly work its way back down my p...ssy lips. Robbie’s cock was still inside me and he began to get some of his cum on his balls so he pulled out.I stroked his cock a few times while I began rinsing off his cum from it.“Let’s get cleaned up now.” I said.“I already was clean until you came in here and had me fuck you.” Robbie joked.“Oh, so you didn’t enjoy yourself?” I asked as I washed. He reached over her ass and rubbed up and down on her pussy. Needless to say my cock was rock hard by now. I stood up so I could unzip my pants and take it out so I could stroke it while watching the young couple. I am not bragging but I have a pretty big cock at 8" long and 4" around. As I pulled my cock out I noticed someone looking through the hole, so I dropped my pants to the floor and grabbed my cock and started stroking it. I would give them a show too, LOL. Then I saw some small fingers. Damn, she is cheating on two people, her husband and the young stud.I was pretty certain that this young beauty was getting it on with Jimmy, or whoever was there at the moment, but I had to make sure. I exited my van and moved swiftly towards the driveway, and under the cover of the clouded moonless night I eased to a spot under what I was certain was the master bedroom. I extended the telescopic microphone up to the window, and adjusted the earphones. This thing was so sensitive, it seemed. "If you love her, prove it now or lose her forever."It sounded melodramatic, but it was the truth and he knew it."Mistress..." my brother's voice quailed, " ... Punish me, please ... I was wrong, I love you. I don't deserve you, but..." he cleared his throat as his voice had gone soft, " ... Please, Mistress Cheryl ... Punish my cock ... My balls ... Anything..."Cheryl was watching him, the corners of her pretty mouth turned down and she was touching her tummy, where their child slept.
