Like I said, Mom knows Dad, what makes him tick, and how to play him. After just a few seconds, we watched her walk over to him, and put her hands on ...his arm. "Of course, Dear. I'm sure you know best about these kinds of things. They're not little boys anymore." She tugged his arm and got him walking with her, away from the rest of us, while they chatted back and forth. It didn't look like they were arguing at all, but when they turned back toward us, Mom was wearing that grin of hers that told. "Do you want to let him fuck me?" She asked quietly."Maybe, after you got whipped right!"Regina stepped back and opened her robe, dropping it, then casually shoved it aside with the tip of one of those all-shy boots. Regina was naked underneath, except for a rather heavy black leather around her waist and a tiny gold key on a light chain around her neck. The years had been kind to Regina. Her body, always exquisite, had barely changed over the years since I first saw her. Except for her. Her jacket was pulled open, exposing her bra. The rope then was wound above and below her breasts, each loop cinched around her arms, then pulled over her shoulders and between her breasts in a bikini harness. He tweaked her nipples through her bra, causing her to moan through the gag. The second rope was tied around her waist, leaving a long trailing piece in front of her. Tina quickly grasped her impending situation, but could do nothing about it. She was pushed down on her side; her skirt. With an undulation of my hips I roll my erection against her, the tip just sliding inside her only to retract a second later.She reaches for my hips and tries to pull me deeper inside.“You are trembling", I observe, "But please contain your alarm, I have a sure-fire method to assist you”I lean forwards, take one trailing end of the scarf, and shove my cock fully inside her.She groans, and her breathing quickens as I use the scarf to tie her right wrist to its nearest table leg. I give a series.
