It was my eighteenth birthday and Mom handed me my presents at breakfast. They were several CD’s and some DVD’s. Dad had gone to work and Mom and Ciara both gave me big kisses and hugs and sang the Happy Birthday song. It was thoroughly embarrassing. Ciara seemed in very good spirits lately and I wondered if she had a new boyfriend. That thought raised my spirits too. Ciara was on a break from college but I had school, so after breakfast I wished them a good day and jumped in my car. At first I thought nothing of the smiles that Ciara and Mom gave to each other when I wished them a good day, but as I drove to school I began thinking there was more to it and something was going on. My first thought was that they were planning some shin-dig for my birthday. Jesus, I hoped not. I put it aside as my classes started for the day.
By mid-day, the thought was back again. I couldn’t leave it alone. That look that they gave each other was driving me crazy. I went to the Admin Office and told the secretary that I was feeling ill and that I was going home. The thought was with me all the way home.
I wanted to see what was going on so I parked on the next street behind our house and cut through the backyard. I stole a glance in the downstairs dining room window and didn’t see anything. Ciara’s and Mom’s car were in the driveway and so was Dad’s. ‘He is never home in the middle of the day’, I thought. There is something definitely going on.
I walked around the house looking in windows as I went. There was no one on the ground floor. I crept in through the back door and silently closed it behind me. I stood in the kitchen a listened. ‘Someone has to be home. All the cars are here’, I thought. I quietly walked to the bottom of the stairs and listened again. I could hear occasional voices but I couldn’t make them out. I crept up the stairs being careful not to step on any of the creaky stairs.
In the hallway upstairs I could hear sounds of sex coming from Ciara’s room. The moans and groans were obviously hers. No one was talking. I slowly opened my bedroom door and stepped in closing the door just as slowly behind me. I fired up my video app and sat down at my desk.
When the screen came up I could see a pair of legs, a pair of balls and a cock slamming up into Ciara’s pussy as she sat back to me. She was motionless as she hovered over the guy’s groin. He had his hands on Ciara’s hips and was pistoning his cock into her as he held her still. Her head was tilted back and she was already exploding into a violent orgasm. She was screaming, “FUCKKK. YYYESSS. OHH MYY GOODDD. OHH YEEEAHHH GIVVEE ITTT TOOOO MEEEE.” I couldn’t see who the guy was and I really didn’t care.
He was relentless as he continued to pound his cock into her at a staccato pace. I had my cock in my hand and was flailing away on it at the same pace this guy was giving it to Ciara. When her orgasm had subsided she bent forward and kissed the guy hard and passionately. I still couldn’t see his face but it appeared that big sister had a new beau. ‘Good for her’, I thought. With Ciara bent forward like that with her tits mashed down on his chest, he couldn’t maintain the same pace and keep his cock in her so he slowed to a stop as Ciara continued kissing him.
