Then the woman shifted her hips the other way and my dick slid across her left cheek and back into its new home, pressed into the crack of her butt. A...ter a second, she shifted again, repeating the sensations that were already depositing pre-cum on my lower abdomen.I must have been dazed, because it took me at least three of the hip gyrations to figure out that the woman had to be doing it intentionally. The amazing part was how motions so slight could be that arousing-the woman was barely. I took my sweet time; I wanted him to get a real good look. As I started to climb down I pretended to slip, and he caught me, one hand on my waist and the other hand on my ass, I could feel his long fingers holding my butt as he put me down. "You okay." "Yes thank you honey, I guess I was lucky you were here to catch me." He smiled and said "I told you, I had your back." He climbed back up the ladder and that boys cock had grown, his shorts were really bulging. Oh what I would do if I could. He ran his hand down her back and across her ass and then pushed a finger inside the leg of her shorts and felt her pussy. It was shaved and smooth and wet. She stood for a moment as he felt her pussy with a finger then she pushed him back. She turned to him and saw his huge cock hard in his bathing bottoms and could not take her eyes off the big shaft. He grabbed her again and pulled her shirt up and felt her tits as he pressed his cock to her crotch. He started kissing her slipping his tongue. The larger dildo was only 1-1/4" thick. Please!The first time he went beyond bottoming out at the end of his rectum, I groaned. The six-incher bottomed out in me ... How could he possibly do that? I looked at Mr. Dennison in stupefaction. It's the only word to describe my reaction."Where is it going?" I croaked.He put the video on hold and Googled 'male anal-rectal anatomy' and showed me my insides. My rectum was approximately 6" deep (I knew that already), and joined my sigmoid colon at more.
