Concept of Akigumo-sensei brought to a love hotel and asked to be a cosplay(?) sketch model, getting into an amorous mood and setting off an ero-doujin-esque aftermath

Sensei♡ How'z your progress? Still at rough sketching?

We only have 2 days left you know? What? You're sure you'll make it in time, you say?

No way! If you really manage to pull it through, I'll model for you wearing the cosplay of your choice♡ Even lewd ones are fine, ga-ha-ha!!

Erm, sensei... What I'm wearing is not cosplay though...

Your new book, as I recall, was going to be a R-18 one, right?

Nuh-uh, I'm fine! Even with erotic poses some time!

Aah, but you know? These clothes, right? If I'm the model... That means... Is it an ero book about me?..

Erm, deny it, would you? Eh? Sensei, your face is all red suddenly?

Wait, is this... We're going to have sex later, aren't we!

What should we do... He's become big down there...
