You fuck her until you cum in her. And then...

"UH...UH...UH...OHGOD...fuck me..." she moans as she arches her back and pushes her hips into yours, no longer caring that you were fucking her in the back seat of her car in a very public parking garage.

"Tell me what I want to hear Erin baby," you tell her as you grab her by the hips and slide in and out of her, feeling her walls starting to tighten up around you as she throws her head back and cums for you.

"OHGOD...fuck my pussy John...I need your cum inside me baby..." she purrs as she lifts her hips up off the back seat and starts to thrust them back into yours, her whole body going limp as you start to cum deep in her tight, slutty cunt again.

"YEAH...cumming Erin..." you announce as you start to cum inside her, her walls squeezing away at your dick as you fill her with several thick streams of your seed, still thrusting away inside of her until all of your cum is inside of her, then backing out of her.

"I...I...think...someone...is...watching...us..." she whispers to you as you both get dressed and prepare to leave the backseat to continue things at your place.

Sure enough, as you open the back door, a van is to your left, and seems to be very interested in your next move with her, and you're pretty sure who it belongs to.

"I think that's fucking TMZ," you mouth to Erin, causing her to start panicking at the thought of her affair with you being exposed for the public to see, "stay here. I'll handle this. And then I'll take you home and handle you again."
