Reject her

For a short moment all you can think about is how she will blow you and **** your dick simultaneously and how great this must be. But then again you look into her face and you realize, this cheap whore will gift you with every disease, the std-commercials warn you about.

"No, i'm fine", you say and retreat a bit from her, as good as your still aching balls allow it. She stops smiling for a brief moment but then her smile returns and she reaches for your dick.

"Oh we can't stop now, you had so much fun and i like you very much", her grip around your dick is painful. "Let's play together somemore."

"No no, thank you", you say again, "i am fine, i think i need a break."

She straightens up and looks down at you. As your eyes met, you know she won't accept your answer.
