Ahh..

Your mouth really is small, huh...?

Maybe it could open a little more...

Aahh

Onii-chan, you sure have a wide mouth.

H-hoh ouhhd! (W-watch out!)

Hohhd ouhhdd (Watch out!)

If I bit you by mistake, you'll get hurt you know?!

Moreover, since my fangs are sharp, you could easily have your fingers cut!

I'm sorry...
