Use her mouth

You pull Sondra to you, pressing her lush body against your, kissing her fiercely. She responds, moaning and squirming against you, then trying to slide to her knees. You give her ass a final squeeze, then push her down as you unzip your pants.

"I'm going to clean your rude little mouth out," you growl, feeling her quiver with excited lust.

"Ohhhhh, yes please," she purrs, nuzzling at your hardening shaft, her slender hands stroking you as she looks up, her eyes seeking your approval. You wind your fingers into her blonde hair, pulling her face to you. Her mouth is open and eager, greedily gobbling your meat, slurping and drooling as she tries to take it all in.

"You're an enthusiastic little suck-slut, aren't you?" you ask as you hold Sondra's hair and fuck her face, relishing the friction of her strong little tongue against the underside of your cock head, groaning softly with each thrust into her soft wet mouth. She's moaning around the shaft in her mouth, her hands fondling and stroking your shaft and balls, her eyes never leaving yours, looking up in submissive joy. She's sucking you hard, eager to make you come, and despite the fucking you've already done you can feel your climax starting to build.

Sondra can feel it too, feeling your cock swelling and your balls tightening. You're very close now, your breath coming in grunts of pleasure. The blonde suck-slut clearly wants to swallow your cream, but perhaps you should mark her, as a final lesson against rudeness.
