Give him what he wants

Now it's too late to turn back. Stepping foward, you start shoving your finger up his ass. It's extremely tight and muscular, so you have to force it a bit, all while the Doctor panths heavly

Once inside you start moving it around, trying to find the prostate, and you must'v foubd it because the lizard starts getting hard. He's not the only one, as you feel your own panths getting tight. It feels good to have such a hunk of a man squirming and moaning under your finger

He's practicaly drooling, so you decide to stop here and pull your finger out of his ass. "All done"

"Done? How can you possibly be done? The book specifies 'anal penetration', don't think you can fool me"

"Wait, what do you"

"PANTS OFF, NOW!"

You pull down your pants and quickly get up on the table, standing behind him. You line yourself up "This might hurt a little" and trust full force

The lizard moans in pain, and you in pleasure. He's extremely tight, his muscular butt contracting around you as you move, slower this time

"You OK?"

"Yes I pant I was only taken by surprise , don't mind me, keep going"

"Allright big boy" you say as you start pounding him with all your strenth. It feels amazing, his hole is tight and gripping, he moans loudly, grips the table as strong as he can and pushes back against you with vigor

You can't help yourself but to feel him up. His massive pecs, his six pack, his strong arms. You don't darei touch his dick, so you simply look as the meat monster trobs and bounces in rithim with your trusts

"I'm cumming!" screams the lizard as his balls contract and his massive shaft beggins shooting tope after rope of tick cum, wasting his potent seed

Seeing such a stud cum hands free from your ass pouding is too much, and you reach your climax as well, pumping your cum deep into his virgin asshole

You both stand there for a while, just taking in the moment. You recover first and quickly try to act normal

"And that concludes your examination"

The breathless lizard gets up and makes his way to the door. Having either forgotten about his clothes or figuring it would be futile to put them on while leaking cum both from his ass and dick, he exits the hud completely naked

With shaky legs he makes his way out and, after a few moments to catch his breath, anounces

"The next one may go in"
