Leaning forward, I grab a nipple in my teeth and suck it into my mouth. Rolling the hard nub between my teeth, I fluttered my tongue over her nipple. ...he has nice tits. Just the right size to cup in your hand with perky nipples. Reaching between their bodies I run my fingernails over Rick's sac making him gasp for air. I knew he liked it. Leaning forward, I use my tongue to bathe his balls catching the base of his rod with my tongue while Tanya's body moves up and down on his cock. Swirling and. I tried to point out that patience was an important virtue for a good lover. He was too anxious to move on for that advice to sink in.I amused myself as I tried to teach Craig how to be a good lover. I sounded like an expert when it came to sex. The truth was that I didn't know much more about sex than he did. But I was bound to know more about the female body than he did since I happened to be in possession of one. And that was what he really wanted to learn about.We lay together with his hand. I close them to kiss the tip, feeling the split of his pee hole just before I parted my lips again and plunged him back into me."Uhhhhhh, gawwwwdddd..." he sighed, looking down at me as his milky white cock began to slide slowly in and out of my mouth. A little burst of precum appeared on my tongue as I held my head in one position and swirled my tongue all around the tip. My hand found its way to the base of his shaft, tightening around it and pulling the skin down and away from the tip, then. With a shocked sob, my arms swing wide, the palms of my hands smacking with a dull thud against the partition wall, and my fingernails scrabble hopelessly for purchase on its smooth glossy surface. I dare a glance downwards, and nearly faint at the sight of how far your arm has gone into me – shit! almost half of the distance from your elbow to your wrist has now vanished from sight!‘AAAH! ... please, wait! Oh, no ... oh, you can’t ... aaaahh, I can’t take it!’ I plead, but my sobs are.
