It was my first time working at a university and the idea thrilled me. Driving directions, parking passes, finding the fine arts department, instructors, studios, etc.. The first time on campus for me was confusing and a little intimidating but I stayed focused as to not be late for my appointment to take off my clothes and stand on a pedestal so I may be viewed totally naked. As I approached the off ramp to exit the freeway I had a few butterflies mixed in with the overall state of arousal I was feeling . I had an erection since leaving home. Entering the studio I was briefed on the poses and length of times by the TA, and then was on my own. I searched for a dressing room or closet and there was none. There was a foyer that was the entrance to this studio so I thought to undress there and stash my clothes behind a cabinet. There was also a row of sinks for studio uses. I was ready to make my entrance. Entering the studio is the most intense experience because being the model for the day , the subject of study, every student has their eyes on me . Watching how I walk , my movement, looking at my feet and hands. Some start sketching me even before I take the stage. I am hired for this purpose, I can expect no privacy while in the studio. I like walking in and without pausing I am naked before I make eye contact with anyone. I walked in, found the stage, dropping my robe as I stepped up to begin my first gesture pose. 30 seconds, 5 minutes, 1 hour. no problem. This is when I check the audience and notice the individual concentration each student has. Some look only at my penis. it is so obvious. Not a problem for me, look all you want at anything on my body is openly on display for you. When class was over I made my way to the room I used as a dressing room. Closed the door behind me thinking how well things went. I removed my robe stuffing it into my gym bag and turning to the sinks to wash my feet. I was enjoying a sensuous feeling , a tension after 4 hours of stimulation. I fondled my half erect penis while beginning to wash my feet when I heard noises coming from all around. I was startled to see 4 doors open at once and the quiet room I was in was suddenly packed with students leaving classes ending . A stream of student artists flowed 3 lanes wide like traffic on the interstate, tip to tail, bumper to bumper. My clothes were across the way behind a cabinet out of reach. My robe somewhere down stream. I was without options except to stand there naked. As embarrassing as this was, I could do nothing but wait it out by the sink , unable to hide my now fully erect penis. I felt the buzz of arousal increasing , with my heart rate and respiration elevated , a noticeable surge in rigidity of my penis seemed to defy gravity curving almost straight up I glance down noticing a sparkle of pre-cum all within a few seconds. ” Oh my god,” I thought to myself . I had no way to hide from view my hard pulsating penis from the 75 or so art students within a few inches from where I stood. Every time I raised my head to see if I could scoot across I saw only the startled faces with wide eyes looking at my swollen penis then a quick eye contact. The hallway echoed with chatter about the naked guy with snickers and remarks about how obvious it was that I was enjoying myself. I was in no position to deny it, as the erotic nature of my predicament played in to my exhibitionist core. A few chuckles and giggles ,Oh my god. he is naked, Oh my god. did you see that? he has a hard on. That must be one of the models I heard one person say. A lot of things went through my mind as I wrestled the bundle of clothes from behind the cabinet, getting home topped the list. Heading to the parking structure, I walked slowly thinking about what just happened. I used my gym bag to conceal my erection as I walked across campus. The drive home was less hectic than the drive to the University, yet a bit of urgency to get home with one thing on my mind. I wasted no time once home through the front door locking the dead bolt behind me. I quickly threw off my clothes on my way to the night stand drawer grabbed my lube laying back naked again, on my bed. With delightful anticipation fondled my heavy cock with my left hand, how wonderful the feeling was. I was surprised to hear myself let out a quiet moan as I applied the personal lube to my swollen penis. Keeping my phone close by in case of a call for me to model and get naked again in public. With this experience fresh in my mind, I masturbated many times afterwords and continue to fantasize/recall the experience . Not sure what the demand would be for my services in my new-found trade. The construction jobs I worked full speed, sneaking away to 1 or 2 times a week to model. That quickly changed excepting every booking focusing on my new interest. The best days are when I am naked from 8-12, 1-4, 5-9 pm. The pay is less than I am used to, more cost in gas, I am fine with that. The amount I spend on lube has quadrupled. I have discovered studio storage rooms are available as dressing rooms if requested.
