More than ever, Kat had become the aggressor, and our foreplay would almost always include me being spanked hard over her lap. Kat would generally end...up on top, riding my cock until she had cum.I loved watching Kat take charge like this, even when she would tease me. Just last night she had taunted me multiple times;"Do you like looking up at my tits bouncing Mark? Your friends sure like to see them don't they?"She could tell this bothered me, but the teasing seemed to turn her on, and. I swear the hookers on Market and Classen dress with greater modesty. I could tell she was losing weight—hard not to considering the tightness of the dress—and I suppose she wanted to show herself off. She still had a bit of a belly though, but without the sidecars, and when looking at her from behind, her narrowing waist made her ass appear more pear-shaped than usual. However, even with the weight loss, her breasts were still heavy, full and firm, nearly popping out of her sweater whenever.

She couldn't stand all the mess and thought it a good time to visit mom and me. Grandma was mom's mother. She was in her late fifties having had mom at a fairly young age. She was petite, just like mom, and kept herself in really good shape. Since Grandpa had died a few years ago Grandma started visiting the gym from time to time and even had a personal trainer at one. For such a young person, I'd always been pretty introspective and had a lot of fantasies most of which I'd never had the nerve to ever talk with to anyone before. I felt so comfortable with Jaime that I did mention some of them to her, but while she listened sympathetically, she wasn't really interested in exploring any of them with me. She thought they were cute though, like me wanting to worship her beautiful feet, or wear panties for her. She never seemed to judge any of them and always.
