They went back into the inner lab, rejoining the two doctoralcandidates and the lab tech. Tina had just finished securing thebracelet to a cylindrica... "blank" and was getting ready to start theultrasound. The two young men were watching the ultrasound's screenwaiting for the image to resolve.K noticed a meter attached to the "tail" end of the bracelet and lookedfrom Rajesh to David. Rajesh smiled."David's suggestion, stupid simple really but brilliant - a voltmeter,"the smile broadened into. They settled into a rhythm as they sucked and licked until Mrs O started to grind herself into his face and moan loudly finally coming loudly as she wanked his slippery cock. She climbed off of him and pulled off his trousers and underpants before getting onto all fours inviting him to fuck her from behind. Ben positioned himself behind her and began to slide his cock into her. Mrs O was facing me as he slipped in and I watched as she closed her eyes, her mouth opening wider and wider as he. This gave me and Cathy plenty of time to talk during the flight. The engines roared into life, and within a few minutes we were on the sky. I was still tired so I decided to have a small nap. Cathy too had a nap. A while later I awoke to Cathys head against my arm. She looked so cute resting against my arm. When she woke she said "hey Hun, damn your a comfy pillow" I laugh. Cathy leaned closer to me and pulled my hand onto her legs. I looked in her direction surprised "we can't dads a few rows. " I smiled. "Ever watch your mother get fucked in the ass?" "Yes" She answered I shook my head. "Jesus, what all went on at this New Years part?" I couldn't believe it. "it was pretty awesome" Kimmy answered, sliding her bikini top off herself, exposing her hard nipples to me, then slipping her bikini bottoms down her long slender legs, exposing a wet, shaved, pussy. I tried to think of something else to say. But I all could come up with was way too dirty. I could never actually ask it. Until.
