Pull her head into your lap

You put your hand on the back of Anna's head and pull her down towards you lap, trembling in anticipation.

"What are you doing?" she hisses.

"Make it look real," you reply insistently.

You hear Anna sigh, but despite this she starts to unzip you trousers and reaches in to pull out your cock. It feels wonderful to have her soft hand holding your rock hard cock. You moan as she slides her hand up and down the hard shaft a few times, then opens her mouth and leans down towards the trembling head. You lean back into your seat in eager anticipation.

Just as her tongue is within less than an inch of your penis there is a tap on the window. Anna jerks her head up in surprise and your cock spasms in a twinge of lust.

"Shit, it's a cop," hisses Anna as you turn, startled towards the window of the car where there is a man looming over the car, "Whatever you do keep my identity secret!"

You swallow nervously and roll down the window of the car.

"So what do we have here?" asks the cop, peering in through the window, perhaps hoping to see you with a naked girl. He shines in flashlight in at Anna, pausing on the large swells of her breasts.

"What's the problem officer?" you ask anxiously.
