As I looked down at her, I noticed her braless nipples straining at her blouse. I moved back in, kissed her and reengaged her tongue while moving my h...and up her side to slide over her nipple and breast, the thin silk of her blouse between us. She moaned in my mouth as we continued to kiss for a couple of minutes more while I felt her and squeezed her nipple.. Then she broke the kiss, sat up and grasped the top button on my shirt. “I have been waiting for this for six weeks, and I cannot wait. Then I put in a pretty good-sized butt plug I had bought the day before, waiting for the knock on the door. After almost 45 minutes he texted from the parking lot to get the room number. I heard two sharp knocks, as I had removed the plug and cleaned my ass. I must have not been prompt enough as there was another, harder knock. I met him in a robe, and he darted inside. He had not cleaned up from the hot day and was sweaty. But he was good looking. And when he stripped down, he was very fit,. I guess I could use a wash, too." As I pulled off my pants and boxers, shirt, shoes and socks, she pulled her blouse over her head and, naked, we walked to the lake. I knelt down to help her remove her shoes unlacing the boots and pulling them off her feet one by one. Again, my shoulder was her brace. Her touch was much warmer on my naked skin. I was glad that I had stayed in shape after college. She was definitely in shape.I offered her my arm for support as we walked into the water to her. "Ohhhhh, goddd Cindy, I'm cumming! I'm cumming in your ass!" Me too, unnngggg!" she panted, "I'm cumming too! Awww cum in my ass!" Cindy had two fingers in her twat as she supported herself on one arm. I went rigid and poked my cock deep into her pussy-like ass orifice. Then I was spurting squirt after squirt of sperm into my sister's guts; and she was whining and moaning and orgasming as I shot!Later that night, Cindy rolled over where we were sleeping together and slid under me, she got me.
