"The cute girl I fap to is taking a shower in my room...Could I try to make a move"? Well...He has the right idea.
And the best way to go about it is...Walking in on her masturbating in the shower, and then start masturbating in front of her as well...? I mean since she likes masturbation so much I guess that's...A valid approach.
Great ending though. Hah, I like how nonchalantly he just asks about her masturbation schedule. My friend, I feel like you don't even need that anymore! Just invite her over more often.
Perhaps on the surface, it was *a-hem* 'faulty construction work' that permitted him to hear "that which ordinarily should not be heard". Then again, it could all be the subtle working of a *a-hem, again* "higher power", determined to either bring about a hookup, or at least contribute to reversing Japan's negative population rate (wink-wink, nudge-nudge).
Whatever the root cause was, ..... "IT'S SUPER-EFFECTIVE!" 💥💥💥💥💥
