" Thank you, Mistress," I replied.Several minutes later, when Mistress was fully satisfied with her massage, she looked at her glass, and asked:"Did m... girl go all her chores today?" Yes, Mistress," I replied."Do you get your uniform dirty?" No Mistress." Did you wait for me on your knees?" Yes, Mistress." Do I have to check the videos?" No Mistress."After several seconds, Mistress shrugged, and grabbed my hands."I'm feeling frustrated, fetch me the black one," Mistress ordered."Yes Mistress!". We lay there stroking each other's bodies kissing deeply and slowly. You push me on to my back and straddle my face. Your soft sweet pussy inches from my mouth. I gladly push my tongue between the soft folds of skin and find your hard little clit. You lean down and take the tip of my long hard thick cock in to your mouth and start to work the shaft up and down with your hand. I suck your hard little clit into my mouth and tease it as fast as I can with my tongue. "Thats it doesn't stop.. Dave could see a chain falling down from this device that almost touched the spreader bar. Larry bent down and snapped this chain onto the spreader bar, causing Dave to bend over a little so that Larry could snap it into place."Now, you see this can be a bit uncomfortable, especially if I add some weights or decide to paddle your ass while you are in that position, don't you think?" Yes, Sir!" Dave responded."No, cock-slut! You do not think when we are having fun like this. You do as you are. I just froze staring at the scene, my 45yo aunt laying on the sofa with her bare white big butt pointing out and my 8 inch dick trying to get inside her asshole. My aunt still didn't make a move, I could hear her breathing and while standing with my dickhead inside her asshole without moving I suddenly felt my aunt moving...her ass was rotating against my dick and I started to push a bit more now 2 more inches was inside her big ass ... that was the most exciting thing it ever.
