Got erection while art modeling in my twenties

I have been many times as a nude model at art class when I was studying arts. I even got paid for posing nude. Most of  the time it was easy, all the painters were experienced and most years older than me. It was easy money just to do a few poses and they painted or drew. I like being naked and it was natural for all.

One time didn't go as expected. At that specific class all painters were quite the beginning of their art studies. Most of them had never painted live models and especially nude models, I think some of them had never seen nude male. All of them were girls, much younger than me.

All started fine, I got on the platform and threw my robe away. I got the first pose and I heard giggles all around me. I was thinking: I'm professional, I can handle this. I should have looked somewhere in the distance, but no I looked right at a couple of girls in front of me. Both were staring right at my crotch, I felt a little twitch in my cock. I tried to save the situation and looked away from these girls, who were right in front of me.

Big mistake, I got direct eye contact with the most attractive girl in the room, and she licked a little bit of her lips. I could not handle the situation any more and I realized my cock was getting hard. And they all saw it, and their reaction got me even harder. Even the teacher, a beautiful married woman in her forties, stared at me with her mouth open.

I was standing in front of eleven women with my eight inches in full erection. Even the girls who had been behind me, had moved to see what others were staring at. The teacher tried to save the situation and said something like, it's just a natural reaction, but everyone heard from her voice that even she didn't believe it.

I haven't been so hard many times in my life, and if I had touched my throbbing hard cock I know I would have cummed in front of them. Finally the teacher knew how to act. She said that lets have a little break and said for me that I can go to the back room for a while. Students left the classroom and I went back. I didn't realize that the teacher came after me with my robe. I turned around and saw her in front of me watching my hard cock. She just asked me if I needed any help with that before she got on her knees in front of me.

She gently touched my cock and kissed the head of it. She said that this has happened before, but not with cock like this. She took my cock in her mouth and slowly started sucking me. She grabbed my ass and started to suck my cock faster and deeper in her mouth. I had never before had such blowjob. She really knew how to suck cock. When she took my cock deep in her throat I could not hold it anymore and cummed deep in her mouth.

She swallowed the load, licked my cock clean and said that now we can continue the art class.

She asked me to model many times after this, but she took care of my cock before the classes. Every time before class she just sucked my cock. While she was sucking she fingered her pussy and at the end I cummed in her mouth, nothing more.

After the class I got a few phone numbers from girls in the class, and some of them I got known better. And the rest of them told what they had seen. My student times were quite fun when people started to know about my size.
