In a sterile, clinical setting, Dr. Hart, a gay medic, performs a series of intimate examinations on a series of eager, aroused patients. He explores every inch of their bodies, focusing on their stiff, throbbing cocks. He measures them, strokes them, and even sucks them, all in the name of "medical research." The doctor's gloved hands work expertly, his fingers grazing sensitive heads and slick shafts, drawing out moans and pleas for more. The clinic echoes with the sounds of wet, sloppy blowjobs and the rhythmic slapping of flesh against flesh.
