Just a quick update.
My sister was in town today visiting. We had Dinner at a local restaurant with our parents. After dinner, we went back to our parent's house to visit some more. My sis said she would ride with me for the ride back. While we were in the car about to drive back, my sis got a mischievous smile on her face. She said, "I bet I can make you cum before we get to the house."
I said, "You're on!" and started driving. She reached over and started undoing my pants. Instantly, her mouth was on my cock, sucking furiously. I was trying desperately to keep my eyes on the road while her head was bobbing up and down faster and faster. My cock was so hard, and it was very difficult to keep from cumming as well as concentrate on driving. Her lips around me and her sucking were driving me crazy.
Somehow, I made it back to our parent's house and pulled around the corner. I just had to cum, but I couldn't get it on my clothes. Whe I was just about to cum i grabbed her hair and pushed her head down on my cock. She started moaning and gagging, but I held her there. I shot my cum deepinto her throat, and she swallowed every drop. She sat up and said, "Damn, that was hot!"
I asked, "What do I get for winning?" She said, "I owe you one" and winked. We got ourselves together and went in. It was so difficult trying to concentrate n the conversations after that.
