But it wasn't very convincing. He looks at me and I tell him to do it, he'll never have another chance like this. He tells Barb he's going to do it an...way. With or without her permission. I almost came myself when I heard him say that. I want to jack off, but I definitely don't want to cum. Not yet. He takes off the blindfold first. Then he takes off his boxers and I am blown away by his size. I knew he was big, but fuck! He kisses her. She starts to respond. She looks spent from all her. In the move I caught sight of her pussy for only an instant, but it was long enough to see that the fur between her legs had been clipped, and while I don't mean shaved off completely, it was pretty obvious that things down there had at least been cropped back at one time.Once my sister was settled in under her sheets she raised an arm in my direction, as if inviting me to join her, and so I too began to undress, though rather slowly at first, as I felt extremely uncomfortable and nervous while. I kept pushing her down faster and faster, deeper and deeper till I heard her gag. She was moaning as I forced her to suck even harder and finally came in her mouth. She remarked how different that was and much bigger my load was. Then she left.I laid there and thought about the BJ. One of the reasons it turned me on so much was because I was imagining that I was the one giving it. I just kept wondering what it feels like to take a cock in your mouth the entire time. My dick was getting hard. The more helpless and out of control she felt, the hotter she got.Her ex and her previous dates had needed to put her down to elevate themselves. It was a fact she had realized only recently, despite her mother's having told her countless times. This surgeon was different, definitely a higher class of chauvinist. Oh, he was still domineering, and he still put her down. But the put-downs were far classier, usually just an expression or a gesture. The ego boost she provided for him was mainly.
