It's not always that easy, but I'd learned to tell by watching and even listening carefully. To put it simply, I'd always figured that it was somethin...g I'd have to learn to be good at given some of my other attributes and I'd been lucky enough many years ago to find a terrific teacher for a couple months in an older woman named Lisa who insisted that one of the tricks was to watch a woman's stomach. It wasn't just to look for movement as you probed down there with your tongue, Lisa taught me to. Then just when I started to lose the edge a bit, like after a few minutes, not getting bored but just sort of getting used to it so it wasn’t quite so exciting any more, he’d start doing something else. Like he’d hold it in and sort of stir it around for a bit each time, or he’d pull it almost out and just move it in and out a tiny fraction right at the entrance, for a minute or two so my pussy would close up inside and then he’d suddenly fuck right into me again and the sensation would be. . 3 or 4 thick white blasts of thick cum shot from his cock onto his belly, then it oozed big, thick, streams of really creamy cum down his shaft for what seemed like ages! It ran down his pulsing, thick shaft, and a pool collected around my fingers, then it ran into his grey pubes and matted there...a really thick pool of creamy white cum was all aorund the base of his cock, across his belly, and on my hand... gasping he said, please taste it...Let me see you lick it off... For some unkown. I fuck her face for a few minutes making her gag on my cock and then take another pic showing half of my shaft in her mouth and the other half out and send it to the two girls. Then I go to watch their reaction when they see their friend sucking on a cock, little realising that it’s their bosses cock and their friend is right up above them.I can see that Ellie has gone red in the face when they get the picture and they both look excited. They’d not been 100% sure if the first pic was actually.
