My wife Cathy is 5-9 tall with a mane of long blonde hair and weighs a solid 205 pounds. She has an awesome 40DD-28-42 body and can fuck my 6-2 tall 225 pound body into exhaustion. She has never really gotten along that well with my younger brother Kurt who is 5-10 tall and weighs 250 pounds. But when the building that his apartment was located in got foreclosed he had to put his stuff in storage and stay with us for a while.
About a week into my brother's stay Cathy stayed up to watch TV and when I went up to bed I passed my brother in the hall going to get a drink of water. About ten minutes later I was about to get into bed when I just happened to look downstairs. Kurt and Cathy were sitting on the couch talking, I couldn't hear what was being said but all of a sudden Cathy moved over and straddled Kurt, sitting on his lap. They were face to face and I hoped they weren't having an argument that would come to blows or anything.
Kurt had his hands on my wife's thighs when she reached down and pulled her T-shirt up and over head, tossing it aside. With her huge chest Cathy normally wears a bra but since she was sitting watching TV before bed she wasn't wearing one at this time and had her DD's in my brother's face.
I was shocked when Kurt started sucking on Cathy's tits and even more shocked that she not only didn't object my wife tilted her head back and sighed. After my brother had enjoyed a generous helping of tit flesh Cathy took his head in her hands and they kissed. Their lips parted after more than a minute and Cathy climbed off the couch and both of them started taking off their clothes. I could not believe my eyes or the fact that I was getting a hard on watching my wife and brother about to get it on.
They were standing next to the couch naked, I still could not hear them except for Cathy looking at Kurt and exclaiming "Holy Fuck!" She then shoved him in the chest, my brother ending up sitting on the couch. It was then that I saw what made Cathy shout. I have a good sized eight inch cock, which pleases Cathy just fine, but Kurt sports a ten incher that is even thicker than mine. My wife dropped straight to her knees and dove at Kurt's hard pecker.
I pumped my own cock to full attention with my right hand as Cathy's long blonde hair fell over her face as her head bobbed up and down the length of the stiff meat between her lips. Cathy is able to deep throat me so it should not have been a surprise but I was still impressed when she swallowed Kurt's full ten inches. As Cathy went down again with her lips to the base of Kurt's pole I shot my load into my left hand.
