My family would spend time with my sister's family and visa-versa they spend time with us. I work a lot out of the area. I came back in town a day early and ready to bang my wife. I quietly sneaked into the house to surprise her. I heard voices in my nineteen year old son's room. Just when I was about to fully open his door thru the corner of my eye I saw my sister's reflection in the mirror on the dresser. She was naked and fucking my son. I kept looking at them fooling around thru the reflected mirror. My sister was five years younger than me and for the first time realized my sister had one of those MILF sexy bodies that you see on the internet. I snapped some photos on my phone and then quietly left the house and got something to eat. When I got back my sister and son was gone. My wife was surprised to see me. I kidded her that I finished the job early just to be with my sexy wife. We went into the bedroom. As I was banging her, she appeared to me in my mind that I was screwing my sister.

I decided to blackmail my sister. We was doing a family cookout, I got my sister alone and showed the pics I had on the phone. Threatened to show it to her husband if she didn't do what I wanted. "And what do you want from me?" she asked. "Sexual play from you." I answered. "No Way!" she blurted out. I started to walk away from her and yelled out to Jim that I have something to show him. My sister quickly pulled me back and agreed to my terms.

I asked my wife to find out my sister size because I may decide to purchase something for her. The following month I needed to go out of town. The day I left she thought I was going to my job site and she gave me a head job. Instead I reserved a motel room and told my sister to meet me there. My sister knocked on the door and I let her in. She wasn't dresses fancy. I handed her sexy undergarments and told her to put them on under the clothes she was wearing. "Why don't I just get naked and get screwed to get it over with?" I reminded her again that it was my terms or Jim sees the pics on my phone.

She changed into the garments I bought in the bathroom and stepped out. "Now what?" I told her to strip dance for me. As I watched her take off her and stood in front of me with only the corset on , my dick was out and I was tugging it. "I didn't know you are that endowed, brother of mine." she said to me. "I feel like I'm looking like a slut to you." I told her to come and suck my cock. I held her head on it. I got up and undressed. Told her to lay on the bed with her head hanging over the edge. She thought I wanted to put my dick in her mouth. Instead I slipped my cock between her tits into the corset she was wearing and came. "Are we done? Did I pay my debt ?" she asked. I told her I was going to eat that fuzzy kitty until I recovered. As I was down on her she seemed to enjoy it. She was holding my head and seemed to push it into her. I told her to go on all fours. I was fingering her vagina while licking her ass. A sexy ass I might say. I think she like what I was doing. While still in doggy position I slipped my rod into her vagina. I heard her moan. I grabbed her long hair and pulled it tight to me as I pounded her. Just as I was ready to explode she requested that I explode on her face while her head hangs over the bed edge. She even had her mouth open for my explosion.

The day I was suppose to leave my job site I get a text message from my sister. It read, 'Call your wife and tell her you be a day late. Meet me at motel room, love sis.' A photo was enclosed of her hairy vagina being spread open.
