Protest and kiss her
From Create Your Own Story
You lean down and kiss her lips while sliding your hands beneath the sheets. She reciprocates and puts her tongue in your mouth. The she reluctantly pushes you away.
Laughing she says, "Look Will, you're a nice guy and I definitely want to do this again. Soon. Just not tonight, OK? Mia, my babysitter will be here early and I'm already worried about what Angie will tell her."
Despite your blue balls, you know you're going to have to respect the lady's wishes.
You get dressed, exchange phone numbers, say goodnight, and leave.
