Orally, of course!

As you squat there, poised over Harley's grimacing face, the urge to use her like an object overwhelms you once again. You grind up on her face without preamble, slathering your dick and balls across the soft planes of her visage until she's **** to slap at your thigh for a reprieve.

"Come on," you grunt, "You got this. Tongue the balls a little - kiss, suck. We need you to get real nasty."

A whine of displeasure issues from the depths of your groin, but it is soon followed by the unmistakable lash of her wet tongue against the very sourest region of your balls. All the while you continue to ride her face without shame, smearing and re-smearing the clown's glossy facepaint across her tear-stained features with every roll of your insistent hips.

"Lick the shaft..." you command, and lo and behold the poor girl does it. The Love Doll's technique is sloppy; almost frantic, as if she believes she'll earn a break from your undercarriage if only she can glaze your dick fast enough. Unfortunately enough for her, though, the events of the last several hours had left you greedy for stimulation - her tongue, moist and dexterous as it may be, is no match for the sensation of scrubbing every inch of your pungent sex organ against her face with reckless abandon.

"MMMMMPPHHHHmmMMM!!!" she shrieks, issuing a cry of muffled protest from beneath your sweaty nuts... But you're far too busy exploring the erotic potential of her nosetip and cheekbones to address it. By the time you're ready to cum Harley has been reduced to a makeup-stained ghoul, the faraway look in her eyes indicating that your plaything had been pushed beyond her comfort zone.

A series of squelches issues from your wet tip as it nestles up against the bridge of her nose, streaks of hot seed shooting out across her cheek, forehead and temple in the aftermath of your harsh affections. Then you let up a bit, lifting your junk from her lips and putting an end to your member's total eclipse of her face with a sigh of satisfaction.

"Great job, Harley," you huff, pressing one hand to the wall while the other pumps your cock back to attention, "...Ready for round two?"

The girl tries to respond, but she barely has time to open her pretty mouth before the bulbous tip of your throbbing dong has drifted forth to occupy it.
