With that I walked over to Vivian and aimed my cock back at her mouth, and as quick as I moved in front of her, she had it back in her mouth. She started off once again by licking up and down the shaft and massaging my balls in her hand. She took the head in her mouth and was moving up and down on my cock, taking it deeper in her mouth with every thrust. I motioned to Dave to come over and join in the fun.
That is all of an invite he needed, it didn't take very long and Dave was naked and laying between Vivian's legs. At first she seemed surprised to have both of us, but it didn't take long and she was enjoying it. Dave was busily licking, and sucking her pussy as she was sucking my cock like crazy. It only took a few minutes at that pace and I was blowing load after load straight down her throat.
I moved back out of the way and watched Vivian and Dave; she was going wild with every flick of the tongue, the faster he would lick the more she would buck her hips. He licked her clit for a few minutes and it wasn't hard to tell she had an orgasm. After she orgasmed Dave moved up from his licking position and slapped Vivian in the lips with his cock, she took him into her mouth as if he had just said the magic words.
Dave was a little smaller than I was, about an inch shorter and a lot thinner, Vivian was deep throating him with every thrust, and she didn't have much choice as Dave had two handfuls of hair and was driving his cock deep into her mouth.
