She felt his throbbing, quivering pulse against her tongue, felt his skin shifting in her mouth as she drew him in and out of her. He groaned again. S...e tickled at his balls, letting the very tips of her fingernails trace electric thrills across his shyest parts, feeling him twitch in response. Her other hand gripped his shaft whenever it slid out of her mouth, working it with firm determination. Sometimes she held just his tip inside her for special tongue treatment while she pumped him this. I panicked. I needed to tell her to lift up so I could breathe, but she just kept looking down at me, grinning. I tried to struggle against my shackles, but I was bound so tightly that I hardly caused any movement.My lungs were screaming for air, and yet she sat there looking down at me with that stupid grin.The pain! The pain! My lungs were in searing agony, but I couldn't exhale.The stabbing pain in my lungs lasted for a seeming eternity while she just sat on me, then I started feeling. " Aye, my liege, it shall be done," says the faithful lieutenant of my wishful thinking. But, alas, it is too late to turn the clock back and pantyhose are here to stay.I applied myself with more vigour to the exploration of her secret places, stroking the velvety flesh at the top of her legs above the stockings and slipping my hand into her knickers over her bottom, running my fingers down the cleft in her buttocks.I moved my hand to the front again brushing the hair between her legs, then. She’s 50, 40DD tits on a nice, slender frame, so it’s all pretty firm and outstanding. At the time of this story we’d been going out for about two years, and had been through most things sexually, but had never brought in a third person. I should add that Diane is a total fuck slut. She likes to be fucked hard, in the face, pussy and ass and called dirty names and generally overpowered. She was always looking for ways to please men. A favorite game of ours, was to watch a gangbang movie while.
