During the warm summer months, when going to the doctor's for a medical checkup or physical. I'll be wearing my favorite new speedo swim suit. It fits me well. my doctor is a female and likes seeing me in snug underwear, looking forward to see them coming off for my physical exam. I'm in my 30's, in good shape too. Once in the examination room, the nurse tells me to just take off your shirt. I have an erection now, as later, the nurse says "Those tight briefs will have to come off shortly. My anxieties are somewhat high,yet enjoying the snug and secure feeling in my speedo. The nurse, then starts the preliminaries, checking blood pressure, then being weighed and height measured on the scale. I try covering my erect penis, outlined in the tight briefs, feeling so nice on me. The doctor comes in to do the major part of my physical. She then says "It's time to bare it all now, strip off those bottoms." The nurse was still in the room, watching me trying to uncover the draw string. I was somewhat embarrassed about having an erection well outlined in shiny blue nylon. I was n't quite ready to give up the tight swim briefs yet. After waiting a few minutes, both the doctor and nurse reassured me I will be fine during the examination. I was playfully pouting like a little boy. My moment to show it all had come, when the nurse untied the draw string, pulling and stretching on the waist band as my doctor watched. I was beginning to enjoy getting getting naked for the physical exam. She continued joyfully pulling and tugging them off my upper waist as tried covering my outlined erection. This was the better parts of the exam, feeling the sheer lycra nylon slowly slipping down below my hips. I still did n't want to take the blue tight briefs off. Now she had them rolled down like a bikini, showing more of the white colored inside lining with the dangling draw string, keeping my erect penis and behind still snug and secure. The nurse gave a big smile, swatting my tightly covered behind. The doctor did cheer her on,with me playfully resisting, yet to no avail. She managed to unsnug my erection from the tight clinging white colored inside lining, freeing it up and now pointing upright. I'm almost naked and it looks like, once the tight blue speedo is off, I wont need a gown. she continued giving several more good pulls and I felt it slip out and off my behind, then my groin became fully exposed as the snug leg bands slowly came free of my privates. Another few pulls on my crotch and I felt my balls drop from the soft secure inside lining of my speedo finally slipping out of my crotch. It was a beautiful sensation, feeling her soft hands with the tight speedo coming off. Now I was naked and ready for the physical examination, as my ankles were freed f rom the tangled blue speedo briefs. Both her and the doctor gave me another quite cheer, then doing the major part of my exam. Wearing tight speedo briefs made me feel better, especially being taken off by the nurse then being naked for most of the examination. My physical did go well and did n't take too long.
