"All right. Time's up! Let's see those portraits." They showed them around. Some were just bad, others were creative, but most of them lacked interest. After the break, they probably expected something more. So, I decided to put the ball back in their court.
"OK. I see we have a winning portrait here. You can now choose the next pose." After a quick consultation with the girl sitting next to her, the winner commanded, "I want you to sit. Open your legs as much as you can. Yes, like that. Show us your thing! And put your hands behind your back."
Me: "Like this?"
Her: "Yup, that's it. 9 minutes."
I sat still in the commanded position, and everyone started drawing. Some were giggling at the way she had commanded the pose and the choice. All of them were sketching while giving sneaky looks at my dick. It was going to be a long pose.
I could hear low whispers: "Open your legs wider," and one of them, behind her hand, saying, "We want to see that dick." The idea of being looked at was not new to me, but for some reason, it felt different this time. There was something implicitly sexual about the request--a sort of "we want to see it all" kind of implication.
Two minutes into the pose, I started to feel like the stares were becoming more direct. The initial reservations had faded, and their eyes lingered longer on my lap. The idea that everyone was looking at my penis was exciting, to the point that I started to feel the blood moving downward.
These situations usually happen but are quickly interrupted by the cold environment of the room (no heating), flexing some muscles to divert the flow of blood, biting my tongue, or simply the fact that there's no real trigger to it. Hence, it only gains a bit of volume before returning soft and small.
Before the shrinking process could start, I saw one of the girls in front of me lifting her eyebrow. It reinforced the feeling of being seen. Another one locked her eyes on my dick, clearly checking if it was changing size. At this point, everyone went silent and kept drawing. I tried to control my thoughts and breathe slowly, but another heavy look derailed my plans. This time, it was the German girl. She first gave it a glance with the corner of her eye and smiled, then she kept pretending not to look by giving a series of quick and frequent glances out of the corner of her eye. The situation was now out of my control. I started getting an erection. When stimulated, I reach my full 8 inches, but this was short of it--I think at least 6 or 7 were already there, without any touching. Luckily, it happened quickly before the end of the pose.
