Dd Sis in Law

Both my sister in law and I are married but we cannnot get enough sex. My wife has no sex drive from medical issues and Donna and her husband, my wife's brother, do not get along. Donna and I have always flirted because I am a breast guy and she has 36dd breasts. The flirting was getting more intense and Donna had mentioned that she was now using toys instead of the real thing. I told her I would love to see her getting off with a toy.

She invited me over and as soon as I arrived we were kissing and fondling each other right in the doorway. Basically we ran to her bedroom taking our clothes off all the way. I began to suck and pinch those wonderful tits and play with her pussy too as she started to moan and buck her hips she brought out a dick shaped toy, I took my fingers out and she put in the toy with one hand and fondled my dick with her other hand. I was getting so hot and so was Donna from her working the toy and me still working her tits. I grabbed my shaft and started to stroke myself because I needed to cum badly just watching her work that toy with those large breasts was too much for me to take. At just about the time Donna started to shake and moan from the orgasm she was giving herself I shot rope after rope of cum all over her stomach and tits. It was the hottest thing I had ever done as my wife was never too sexually adventureous. We will be getting together again but we did agree that it will only be mutual masturbation.
