Oh? ??? Shiraha-kun, what's wrong...?
Are you feeling unwell? Did you accidentally inhale something bad while working on your research?
You're so diligent, you must have gotten carried away...?
Oh dear, it seems that's not it? You've taken that new medicine, haven't you?
That's a pleasure-inducing medicine I created, Shiraha-kun, you know?
Oh dear, that's not good, juice is leaking from between your legs, isn't it?
Your body's getting hot too, isn't it?
Well, I suppose it can't be helped... Shiraha-kun?
I'm your supervising professor, after all... right?
Shall I take responsibility and satisfy those beautiful big breasts and that pure-looking lower mouth of yours with my dick...?
See? Now that I've inserted my treatment rod deep inside your narrow cavity, it feels even better, doesn't it...?
More, Shiraha-kun? Really? I'll give you more.
