Jan Pribyla came in for a Czech Up, with Dr Ivan Cakovsky and Sister Sasch Borodin. Jan had a bad stomach and it needed some investigation. So he is told to get undressed and put on the white surgical smock. When he has done that The medics put him in the chair and take some vital tests, like blood pressure and temperature, using the thermometer in the dick trick. But he fails to get a reading, so he then tries the ass, and is more successful. Ivan decides that further examination of Jan's ass is required, so he gloves up and slides a finger in. At the same time Sascha starts kissing Jan and plays with his cock. Then Sascha also dons a glove and both he and Ivan finger Jan's ass. Ivan then sucks on Jan's dick until he gets it fully hard. Next it is time for Jan to get a taste of some dick, and he sucks Ivan and Sascha in turn, while wanking himself. But Ivan doesn't forget all about his duties as a Dr and gets the proctoscope and checks Jan's ass some more. It seems that it needs further attention, so Ivan has Jan sit down on his throbbing dick for further penetration. Jan rides Ivan's hard dick, bouncing up and down, as Ivan sucks on Sascha's dick. A quick change of position allows Ivan better access to Jan's ass, and Jan can also suck Sascha at the same time. Finally Ivan and Sascha want to give their loads to Jan, so they unload and he sucks them dry. The guys then kiss and bring the scene to a very nice conclusion.
