Oh ???? Shirahane-kun, what's wrong...? Are you feeling unwell? ? Did you smoke something bad during your research? You're so serious that you're so engrossed...? Oh no, it seems different, doesn't it? Did you drink that new one? That's a pleasant kusuri that I made, Shirahane-kun? Ahhhh That body has become hot too, right? It can't be helped... Shirahane-kun? I'm Shirahane-kun's professor... Right? Let's take responsibility and satisfy those beautiful big boobs and pure lower mouth with my...? Well, if you put my treatment stick all the way to the back, it will be even more disgusting and better...? Bigger? Shirahane-kun? I see, I'll do more.
