You let the chemicals her

She pushes him back on the exam table, rubbing his big cock though his pants, as she says, “Let’s get your pants off John. Let me jack your big cock.” She pulls his pants down and his giant cock springs up erect and dripping cum from his oversize piss hole. She looks over to Traci and says, “Prepare ISO procedures, code blue.” Then she turns back to his jerking cock as she grips it with her hand, rubbing up and down the massive shaft, rubbing her hand over the sensitive head. He lie back and enjoy the sensation of her hand on his cock, the sensation he hope will be replaced by her cunt very soon. She moaned, “God hurry up Traci, he is getting to me. I can feel the sexual desires grow within me; he's body is producing a tremendous amount of very powerful pheromones, I don't know how long I can control myself."

"God his cock looks so good," Karen lowers her mouth and stretches it wide covering the fat head, and running her tongue all over his fat cock head. He moan loudly as her mouth covers his boner, then he reach orgasm and he can feel the shots of cum rocketing from his cock head, filling her mouth with his hot jizz, then sudden the sensation of her mouth on his cock is gone, and he look up to see that Traci is pulling Karen from the room. He tries to sit up and he realizes that Traci has fastened him into restraints while Karen was jacking him off and sucking his cock. He cannot move now and as his cock finishes spewing its massive load on his stomach he realize he have been tricked and are truly trapped.

“Activate the negative pressure seal,” he hears Karen say as the door to the room hisses shut. “That will keep his pheromones from getting to us.”

He screams in frustration but he cannot do anything other than look out at the girls through the window. Karen flicks on the microphone, “I am so sorry John to have to do this to you, but I don’t want you to hurt yourself, or anyone else until I figure out what to do with you.” Then she turns to Traci and says, “Damn I got a good shot of his chemical sexual activators. I can think of nothing now but running back in there and having him fucks me with that big cock.” He can see that Karen has shoved her hand down the front of her slacks so she can masturbate as she looks at his jerking cock.
