And then it happens. She wraps her wonderful lips around your cock, and sucks you for all she's worth. You feel like you are crossing the point of no return when she suddenly stops, and whispers:
"That was really good. You're acting just like you can't control yourself!"
You whisper that you weren't trying to control yourself. You feel like crying again you are so horny and close to the edge, but now she's taken her mouth off your cock, and so you can't cum without spilling your seed!
