Your cock, of course.

"Do you want to see my cock?" you ask, way too casually.

"No thanks," she says, her face flushing red. "I know what a penis looks like."

"You haven't seen what this one looks like," you say, feeling yourself getting harder at the sight of her embarrassment.

"It's really not a big deal," she replies, licking her lips. "I've seen them before."

"Listen, I'm just going to show it to you," you say, your cock practically bursting out of your pants. You wonder just how many cocks this blonde slut has seen before.

She holds up both of her hands as if to tell you to stop, but only a single word comes out of her mouth:

"Okay."

Slowly, you unbuckle your belt, before unbuttoning the top button of your jeans and yanking down the zipper. You still can't take your penis out yet - it's way too big. You pull your pants and underwear down a few inches, then reach inside and draw it out. It's rock-hard by now, throbbing and pulsing as it stands at attention just a few feet away from this suburban housewife. You begin to stroke the long, thick shaft, smiling down at her.

"So?" you ask.

"Okay," she says, her voice sounding completely detached from her mind. "I've seen it now."

You take a step towards her, her eyes still locked on your raging hard-on.

"Do you want to touch it?" you ask, stroking it in her direction.

"Okay."
