Laughter

"Oh my god!" you hear her gasping while her jaw drops, you think she's impressed and you're right, but not in the way you think.

"HAHAHAHAHAHAHA!" you hear Kat laughing hysterically which hurts your pride deeply.

"What the Hell is that? Is that-" she starts to laugh again "Is that supposed to be your penis? Holy crap! Even my pinky is bigger than that!" she then mocks you by waving her pinky finger.

"Don't you feel embarrassed by showing that to a girl? Like, look! Even your tiny balls hang lower! That has got to be the smallest one I have ever seen in my entire life!" she says after laughing.

However, hearing these humilliating words turns you on as your penis starts to get hard. "Oh my god!" she says "It's standing up! Is this turning you on?"
