Sexy str8 guy Karel Omanak is due for his annual check up, so he attends Dr Nikol Monak's clinic. Nikol, a very handsome str8 doctor has some questions to ask before he examines Karel. Karel takes off his tee shirt and sits on the exam table so that Nikol can listen to his chest. Then Nikol feels Karel's neck and checks his eyes. Karel hops off the table and bends over for Nikol to feel his back. He seems to find something that needs further examination. So he tells Karel to strip to his underwear and lay on the table, face down. Dripping some oil onto Karel's back Nikol begins to massage it, lowering the underwear off that sexy ass. Nikol's hands work over the back and down on to Karel's ass. The Karel turns over and Nikol pulls the underwear down to release the stiff cock. His hands work all around Karel's groin. Then he leans forward and kisses Karel's sexy chest as he takes hold of the cock and wanks it. Nikol's mouth closes around that cock, sucking it hard. He sucks and wanks on the cock, moving up to kiss Karel too. Then Nikol pulls his own stiff dick out and Karel eagerly grabs it and begins sucking. Nikol's hips thrust as his big cock is in Karel's mouth. Nikol gets naked and moves Karel, bending him over the table so that he can slide his fat cock into that sexy ass. His massive cock slides deep into Karel's ass, fucking it hard. Nikol slap the ass too as his cock pounds the tight hole. Karel takes it so well, enjoying that cock opening his hole so wide. Nikol fucks hard as he pulls on Karel's hair. He lays Karel on the lays, legs in the air, to fuck him some more. That big cock slides in and out of the hot hole as Karel grabs his own dick and wanks it. The hot cum is soon shooting out of Karel's cock as Nikol continues to pound his ass. Karel milks his cock dry as Nikol's dick rams in and out of his hole. Then Nikol pulls out and quickly dumps his cum over Karel. Then he pushes that sticky cock back into the hot hole again to end a wonderful Czech Up.
