My Brother in law has to come by my hotel to get something that belongs to my sister, well maybe I took it so I could get a chance to be alone with him a little bit while sissy is at the dr and we are all away for a reunion. He comes in and finds me chilling in bed in just my bra and panties. Hes a bit shocked to see me so under dressed but its a pleasant surprise. We make a little small talk about how him and my sister are now on kiddo number 5, and Im thinking he must really got some good swimmers. As he starts talking about possibly getting the snip, I take the chance to pounce and seduce the Irish stallion and trick him into pumping me full of his spunk to get me pregnant. I pull him in close, start taking my clothes off and Ive got him in my grasp. It doesn't take much convincing to let me suck his cock, and it wont be long til hes itching to get it inside my tight wet pussy. My bro-in-law fucks me hard and deep in missionary, before getting those back shots in doggy style. Doesn't it feel so good not wearing a rubber with your wifes younger sister. We finish in doggy as I beg for him to unleash his load inside my pussy. Its a good thing im on birth control, he chuckles, but am i?? hehe
