My Quiet Best Friend's Just Tongue-Tied

For some reason, one day Ohdai woke up with the power to see how turned on people are. He thought to himself "Hey, I could meet horny girls!!", only to notice that his silent and poker-faced best friend's lust gauge was bursting at the seams. Apparently, if the gauge isn't depleted regularly, he could end up becoming a molester...!? He'll be okay if we take care of "it" before the gauge breaks, right!?
