She notices you getting hard.

Piper happens to look down and she a bulge growing in your pants. "What's that?" she asks, "I mean, I know what is but... how? I know for sure that I froze you."

You look down at yourself, think that she must be wrong, and you try to move your arms. They don't budge, you were frozen. But somehow your dick had freed itself from her power and currently it was liberating itself from your pants, obliterating your button fly.

Piper looked on in astonishment as your cock bobbed in the air, ever growing thicker and longer. When it seemed to have reached its maximum size, she moved closer.

Now down to her knees, she inspects you member thoroughly. "Damn," she says, "I didn't think they got this big." She wraps a hand around your cock and begins stroking it gently. Your cock throbs against her palm. "Now there's a proper response," she mumbles just before she slides her tongue across your shaft. "Maybe your lips will loosen if I open mine a little," She says.
