Today is my first figure drawing class since entering art school. And to my surprise, it's nude drawing! And the model is a student?! A girl gets naked right in front of me. I don't know where to look. The instructor then says that it's unfair for only the model to feel embarrassed, so everyone should get completely naked too! Well, I'm the only guy, and if I take off my clothes in this situation, my erection will be completely visible! I thought, but I couldn't refuse, and in the end, we all ended up completely naked! What's more, when we model in pairs, we get to touch the naked girls all over! My crotch gets touched all over, and I get a full erection! What's more, to express the dynamism of the skeleton and muscles, we all draw the models seriously entangled with each other!? It's now a situation where it wouldn't be strange if I inserted it at any moment! The atmosphere in the classroom is quite strange! There's no need for shame in art, but... this is just too erotic! Even the teacher's breathing is getting heavy and he's getting turned on! It's seriously dangerous!
