I sat there watching my sister lick her friend’s ass and thought “I’m the luckiest guy in the world!”Then I realized that Judy’s ass was exp...sed to my view. I could make a better decision on who’s ass was better if I sampled both asses. I moved around and spread my sister’s legs and started licking her ass cheeks. She moaned, raised her pretty ass in the air and waited for me to get it.“I need to examine the competition” I said “You know, to see who has the better ass.”With that I spread her. Shelly was every bit as hot as her mother Rebecca and was enthusiastic with every opportunity to expand and practice her sexual skills anywhere, anytime. Bobby was thrilled that both of them also encouraged him to engage in physical activity outside the bedroom, and not just sexual antics.Shelly had scored a 6.1 on her CAP evaluation and had begged to be Bobby's number two sex toy. Marvin had left instructions that gave Shelly freedom of choice regardless of her score. Kim's bedroom in her. Then she dropped to her knees and reached out and unbuckled his belt and pulled down his zipper. Pulling his pants and shorts down at the same time she exposed the largest cock she had ever had. It was already fully hard and over 8". It was so big around that she could not get her fingers fully around it. "Oh, how nice." she said as she kissed the tip of her newest friend and licked off the pre cum that was already coming from it. Tina slipped her lips around his shaft and within a few. Once refilled to a bit over the tops of my legs, she moved me to sit up with my back against the back of the tub before climbing in with me to lay back against my chest. My hands were pulled to her chest as we just enjoyed relaxing together. She got out first and made sure I was getting a good look as she pulled off her bikini bottoms. I was inches away as she dried herself between the legs, wrapped a towel around herself and then got me out of the tub. Once she had me dry, we worked together.
