She kicks it up a notch

"Let's get this party started!" Steph squeals and unzips the small soft sided cooler she brought. She pulls out three Jello shooters and passes one to you and Brianna before down hers with a quick gulp. She tosses the empty glass back in the cooler and pulls out another shooter and downs that as well before wiping her mouth with a giggle as a late model Mustang with tinted side and rear windows pulls into your spot.

With a happy little squeal, Steph bounces over to the driver's window, her pert tits nearly falling out of her orange micro-bikini. The driver, a sharp faced man with a stubbled beard, looks her over appreciatively, although his eyes miss nothing of you or Brianna.

"Hi handsome!" Steph giggles. "Thanks for dropping in to support our charity car wash. I'll be happy to take care of you!"

"That's great!" he laughs easily. "I need a lot of taking care of, especially if the caretaker looks as good as you!"

"You're sweet!" Steph laughs, blushing slightly as his eyes roam over her body. "Any special requests?"

"Actually yes," he answers with a sexy grin. "I'm a terrible housekeeper and the interior of the car is a mess. How about you tidy up inside while your friends was the outside?"

Steph looks into the car and gives another giggle that makes her flesh quiver deliciously. "You are a messy one," she laughs. "I'd be happy to. We want you to leave here satisfied." She sways around the car to the passenger door, grinning at the you and Brianna as she gets in.

"Stupid slut," Brianna mutters as the two of you start to wash the car. "Getting in a car with a strange guy. She doesn't have a brain in her head."

"Oh calm down. Nothing's going to happen while we're outside washing the car and looking through the windows. Let her have a little fun. You're just being bitchy because she might do better than you."

"Fuck you Lisa!" Brianna hisses. "Having big tits doesn't make you better than everyone. Anyone could come here almost naked and have guys tripping over their dicks chasing after her."

You bite back a reply, not wanting an argument with Brianna, who is clearly getting angrier. You soap the windshield, looking into the car in time to see Steph's head bobbing in the driver's lap, one of his hands holding the back of her head. You give a little gasp, and look to see if Brianna has noticed, but she is muttering to herself, still grumpy at the world. You realise that she can't see into the car through the tinted side and rear windows and decide not to tell her. She's angry enough as it is.

Steph is stroking the driver's cock with one hand, her other fondling his balls as she sucks his meat. His head leans back against the head rest, his eyes half closed in pleasure. He sees you watching and gives you a sexy lazy smile and a wink.

You bite your lip as you start to lather the windshield, pressing your boobs against the glass and pulling one side of your bikini top to expose a nipple. He grins wider and his hips start to rock, pumping his cock into Steph's sucking mouth. He grabs a handful of her blonde hair and holds her head as he face fucks her, all the while watching you and your ripe tits pressed against the glass.

Steph's head is bobbing rapidly, and from the intensity of his face he's very close. You watch fascinated as she performs, feeling your own pussy growing warm and wet, half wishing you could take a turn with him.

No sooner has that thought crossed your mind when he tenses, his body stiffening as his hand holds Steph's head down. He throws his head back, his eyes closed and mouth open in ecstasy, his hips rocking as he empties his balls into your friend's mouth. You watch as Steph finishes him, swallowing most of his load with only a trickle of his cream on her chin. She sits up, giving him a come stained grin and wiping her mouth. He passes her a hundred dollar bill, and winks at you as you start to rinse off the window.

Steph gets out of the car with a happy laugh, picking up a cloth to help dry the car. The driver runs down his window and grins at you as you dry his door.

"Thanks for helping out babe," he laughs, handing you a twenty. "Those tits of yours are truly inspirational."

"Thanks," you giggle, then lowering your voice you add "You should see how inspirational I can be with my mouth."

He gives a short bark of laughter. "Another time maybe. Your blonde friend drained me dry. She's got my number, so if you feel like showing me how inspirational you can be, hit me up sometime." With another laugh he starts the car and pulls out of your space as you turn to see Brianna nearly spitting with irritation.

"A hundred bucks! Just because you picked up the mess in his car? What the fuck, bitch? Did you fuck him or something?"

"He tipped me another twenty," you add, watching as Brianna's eyes widen in anger.

"That asshole! He didn't even thank me. What a fucking prick!" You shrug in reply and lean close to Steph as you add your twenty to the donation jar.

"You might want to wipe your face again," you whisper. "You've got some at the corner of your mouth."
