Stick around and watch, perhaps you can lend a helping hand?

Gadget moved over to Anna and pulled off her robe, he then began to check her ears, eyes and mouth. He moved down her naked body, checking her throat and then began to inspect her breasts for lumps and the like. As you watch Gadget fondling and squeezing Anna's huge tits you feel your crotch twitch and begin to stir so you walk over to Trish's chair.

She jumps in surprise as you pull down the front of her robe.

"It's okay," you assure her, "I've worked as Gadget's assistant many times, I know exactly what I'm doing."

She relaxes slightly as you grab an instrument at random and pretend to check her mouth and eyes. You quickly throw the device aside and grab her large breasts, squeezing them. They are wonderfully full and firm, topped by small, hard nipples. As you roll the massive orbs around her chest, groping and molding them you glance over to see Gadget has Anna's legs up around his shoulders and he is probing between her thighs. You can't quite see if he is using any medical tools or not but decide to wing it.

You give Trish's boobs one last squeeze then move between her legs and lift them up onto your shoulders. She gasps as you rub your thumb down the slit of her cunt, then use two fingers to spread her labia before pushing a finger up inside her.

Trish is gasping on the table as you start to slide your finger in and out, rapidly finger fucking. You can't seem to tear your eyes away from the sight of your finger pumping in and out of her lovely cunt so you don't bother checking to see what Gadget does next. You push a second finger inside her and Trish arches her back with pleasure. With your free hand you start to stimulate her clit.

Suddenly there is a cough from behind and you turn to see Gadget has finished his examination of Anna. You immediately pull out.

"Ahh just warming her up for you Gadget," you say with a grin. On the exam table Trish is writhing with pleasure, she was so close to orgasm and is now frustrated.

You'd better hurry on to the first class before you get into trouble
