My sister Marie is going to be married in a couple of weeks time. The guy she is marrying is a dolt as far as I am concerned. His name is Bruce and I thought my sister could do much better than him. Marie knows my feelings and we have spoken about it. One Saturday I popped over to her apartment. Luckily Bruce was nowhere in sight. Marie was doing some wedding day preparations when I showed up.
My sister opened the door and let me in. I sat down in one of the chairs and watched as my sister was getting things ready for the big day.
"Are you still going through with the wedding?" I asked her.
"Stop asking me that Terry, you know I am not backing out."
Marie was tired of having this conversations with me. I gave my sister a good look. Marie had dark hair down to the middle of her back. She had a pretty face and although she was on the thin side she had good sized breasts. I often thought what it would be like to bed down with my sister.
"I am always available if you drop Bruce," I said.
She gave me this look that said I was acting like an asshole. As I sat in one of her chairs I moved a hand down to my crotch. I touched myself outside of my pants. My sister looked over at me.
"Are you playing with yourself?" She asked.
"I was just thinking about you and me."
"Don't be stupid," she told me.
I wasn't being stupid at all, I said to her. We would probably be good in bed together. My sister just shook her head. I decided to test my theory. I pulled my pants zipper down and I reached in and pulled my cock free. Marie turned her head and caught me with my cock in my hand.
"Stop that!" She scolded me.
I told her to come over and make me stop. She walked closer to me and I reached out and caught hold of her arms. I forced her to kneel down on the floor in front of me. My fat cock was dangling just inches from her mouth.
"Suck on it Marie," I told her.
She looked at my prick for a few moments and then she parted her lips. I moved forward and my cock was now in my sister's mouth. Marie gave into me. She was now bobbing up and down my prick. I placed a hand on the back of her head. I was making her go right down to the root. My sister knew exactly what to do. She had one hand on my balls and the other at the base of my dick. It didn't take long before I was fully erect.
I pulled away and then stood up. My sister's eyes went wide when I started pulling her clothes off.
