you decide since the doctor is watching its time to have a little fun. you pull out of the lab tech and rip off her lab coat. she lets out a little shriek as you do. you begin wrapping your cock around her tits and her wrists bringing her arms to be held behind her. then you plunge your cock inside again and start to fuck like no tomorrow. she screams and moans which kind of pisses you off so you start to squeeze her tits in your vise like grip. she starts crying and moaning and struggling in effect rubbing your cock getting you off. "wow this new cock is strong" you think "i wonder how strong it is" you begin lifting her off the ground as you fuck. "wow i could do chin ups with this thing" the doctor is on the other side of the room scribbling fast and looking like an excited kid in a candy store. the lab tech's crying slowly turns into heavy sighs and moans. " i think she is starting to like it doc!" you say playfully. "well she is a dirty little sex addict. plus she can type fifty words a minute..." the doctor retorts. then you pull out of her cunt and start to push at her asshole. "oh yes give it to me!" the lab tech begs. you chuckle and force your way inside. she screams "oh god!" and you continue your fucking. her tight ass grips your cock as you repeatedly jam inside her. you can smell the pussy juices starting to flow from her wet cunt. you position her over your mouth and begin slurping and licking her clit. she screams and moans as she has a shuddering orgasm on your tongue. you lick up all the juice and pull out of her ass and wave it in front of her face. she reaches with her tongue just barely touching the tip of it. she looks down at you her eyes pleading and begs "please let me suck it" you smile fiendishly and ease it into her waiting mouth. she sucks it in and her tongue rubs all over it inside her mouth hitting all the sensitive spots. you can feel your balls begin to tighten and you pull out squirting on her face and getting some in her mouth which she swallows. "mmmmm" she moans. "you like that baby?" you ask. she nods. you take your cock and gather the cum up to her mouth and she eats it all. the doctor on the other side of the room starts clapping and cheering.
