Mark, a lanky twink with a soft, unassuming demeanor, enters the sterile clinic, his heart pounding with anticipation. He's here for a routine check-up, but the doctor is none other than the infamous gay medic, known for his... thorough examinations. Mark's penis, initially limp, hangs flaccid between his legs. The doctor, with a mischievous glint in his eye, begins the physical, his gloved hands exploring Mark's smooth, youthful body. As the exam progresses, Mark's cock starts to twitch, growing harder with each expert touch. The doctor, now sporting a noticeable bulge in his scrubs, continues, his professional demeanor cracking as he takes in Mark's growing erection.
