I'm 4 years older than my sister. She is the girl who was drop dead gorgeous and I was average. She married a hunk. I love my husband but he is very vanilla, and cums quick. We have been trying for a baby two years but nothing yet. One day my sister and her husband were in their car, I was talking on my cell to my husband. My breast was inside the window, when my sister rolled the window up almost pinching my breast. We all had a little laugh. We were at our parents for a hangout. All had drank to much except me, so I could drive my husband home. I went to the toilet and was closing the door when my brother-in-law entered and closed the door. His line was he was worried about my breast and needed to check it out. I don't know why but I let him lift my shirt and let him fondle and suck my breast. I got very worked up quick having never been with another man much less a hunk of any woman's dreams. I had on loose shorts so he had his thumb inside me before I realized I didn't stop him. I had an orgasm and then I noticed my shorts and panties were off and he was naked. He has such a fine penis not to long but had a shape I loved. I was going to give him a blow job when he leaned me back on the vanity and lifted my legs over his arms. He was inside me and I didn't care my husband, sister, and parents were located on the other end of the house. I was so hornie and almost passed out when he finally cum inside me. He got dressed and about to exit and I told him we were wrong and not to do it again. About 2 weeks later I was at Home Depot when he came up and spoke, helped me with my purchase. After checkout we were in his truck making out like high school kids. I could barely walk to my car being paralized from my orgasms. I did get pregnant but my son is no doubt my husband's. My daughter could be fathered by my brother-in-law, I can't determine yet. We aren't often meeting up now days, but my husband gives me sex buzz and my dildo and brother-in-law gives me body knumbing orgasms. I feel guilty often for what I do but when I feel slutty I am open for the opportunity.
