Please Don't Tell Anyone!!!

O-M-G Sunday may embarrass me to death! It wasn't a date, but it was a disaster. We had a family outing at the lake. I caught a ride home with my brother and his family. I am just a 37 yr old guy and I couldn't help it.

My brother has an extended cab pickup. He and his wife were in the 2 front seats. I had to share the backseat with his 3 kids. Two boys and his 13 yr old daughter. We couldn't all fit and daughter didn't want to sit on her brothers lap. She was wet in a tiny bikini and a towel wrapped around her. She was sitting on my lap. I tried to think of anything else but it happened. She was bouncing around and grinding on my crotch. I wanted to jump out of the truck as I started getting hard. As my dick got hard she noticed and turned around at me with a grin on her face. Maybe it was me but it seemed like she started intentionally moving her tiny ass and grinding on my dick. By the time we got to my house I was super hard. I used my bag and towel to hide it as I got out of the truck. I think she had fun doing this to me! I pray she doesn't say anything.
