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