Oh? Shiraha-kun, what's wrong? Are you feeling unwell? Did you inhale something bad during your research? You're so serious, you must have gotten too absorbed in your work... Oh my, oh my, it seems I was wrong. You drank that new medicine, didn't you? That's the pleasure-inducing drug I created, Shiraha-kun. Oh dear, oh dear, look at that. Love juice is leaking from between your legs. Your body has become so hot, hasn't it? It can't be helped... Shiraha-kun. I am your supervising professor, after all. I'll take responsibility and satisfy those beautiful big breasts and that pure-looking pussy with my cock... See? It feels even better now that I've inserted my treatment rod deep into your tight hole, doesn't it? More? Shiraha-kun? I see. I'll give you more.
