Here is an incident which took place before the marriage of my sister. This happened with me 3 years back.I live in a middle class family. I live with...my parents and my sister. My parent does job and goes ever morning for it. My sister takes care of me when my parents go outside for some their office work. My sister is of 23 and a beautiful looking girl. Her name is dolly. From my childhood my sister would take care of me and helped me in everything in which I needed help. She never refused me. Graham came upstairs and called out for me.“I am in the shower babe, what is wrong?”“I forgot my briefcase, I left it by our bed, I have it now.”“Oh okay babe, have a good flight,” I called out.“Open the door and give me a kiss.”“I am in the shower.”“So, give me a goodbye kiss.”I put my head under the shower to wet my hair and quickly put my robe on. I opened the door, just enough to poke my head out and kissed my husband, a quick peck on the lips.“Bye babe,” I smiled, as he walked out of our. About 10 minutes later she came out from the bathroom and my cock shot up to full length, 8 inches, and was most definitely harder than it's ever been. She walked out and was wearing a tight blue almost see through bra, with blue panties and black tights. I could feel my cum building up. She let out a little high pitched moan and got on top of me humping my bare cock. "Wow it's beautiful." she said as she squeezed her tits. After licking and sucking on my neck she stuck out her long, wet, soft. She was in her early twenties and wearing threadbare jeans with frayed cuffs hanging over her boots and a hot pink t-shirt was covered by a beige corduroy jacket resplendent with a darker brown faux fur collar at the top. Her hair was blonde with pink sections, more than streaks, and a wad of chewing gum was in her mouth. Sabrina thought the clothes looked like they’d probably come from Goodwill or some other charity and she wouldn’t even use them to clean the floors in her home- if she cleaned.
