After a few moments -- I swallowed his load, I think he did the same.“Jesus!” Mark said, as he pulled his cock up out of my mouth, relaxed, and la...d completely onto me...I exhaled deeply, “yeah”. And another pause.There was a bit of calm, peaceful silence, then Mark spoke: “Well bud, I think this semester is going to just be amazing now that we’ve got this whole situation figured out.”“Huh?” I said.“Yep. This situation. It seems you're an excellent sex slave, buddy boy." Oh am I?" I mocked. Both girls touched each other arms, and giggled, not letting on they saw his hardening cock.Tracey unlocked the door. "I hope you don't mind, but I’m going to run upstairs and change out of these tight jeans. Casey, why don't you show him the den, put on some CD’s and get comfy."Casey escorted Mike into the den, switched on the CD player, and then said, “Excuse me a minute Mike, while I go and get three bears from the fridge.” She walked off toward the kitchen. To his surprise Tracey came back. She started to buck her pelvis upwards, taking him so deep inside as a shudder suddenly filled her body and she hid her orgasm in the pillows. I heard a muffled sexual moan then groan as he pounded her deep, slapping himself against her hard as I watched his balls play against her and his cock being swallowed ever deeper.I could hear him breathing hard now, he was close also, pounding fast, fucking my wife and kissing her more and more, on the neck, cheek, lips, tongues connecting and then both. Now I was in nothing but my bra.But not for long.Vee looked up and saw that and even as she continued the rhythm into my pussy with her finger, she reached up with her free hand and pulled my bra off of me. My breasts were so firm and my nipples were so hard and she did not hesitate in tasting one. Her lips wrapped around my soft puffiness as her finger worked my pussy like magic. Now the feeling inside me was raging. I was on the verge of an orgasm. A very intense one at that. And Vee knew.
