Time for a tune up [MF]

Pulling into the mechanics, you knew you were late. Kids and husbands do that to a lady. You made the appointment but life had a way of causing things to not work out. You called ahead to let them know, Mike answered and said it would be ok. You've been going to this spot for a few years and the guys here always took good care of your car.

Walking into the door, you notice its quiet. Very quiet. Looking at the clock on the wall, you know why. Its almost closing time. Good thing you only needed an oil change and tire alignment. Mike was usually quick with these little tasks. You look around and see him, staring at a computer screen. He hasn't noticed you walked in yet.

Mike was young. Mid 20s. Almost 6 feet tall with broad shoulders. His big brown eyes gave away a kindness. He always wore a smile on his face. His dirty blond hair was messy from a long day of work. His overalls were stained with the efforts of constantly striving to make his customers happy. You notice his large hands, covered in grime, moved with confidence. Mike has been doing this for years.

He looked up at you with that welcoming smile. Was that a dash of alarm you noticed? His hand moved quickly to click the computer mouse as he stood up. Hey Mia, he said, you made it in just before the bell. Was he blushing? Putting it out of your head, you said you were sorry for being late, but he dismissed it and said he was happy to see you again. Getting the work done on your car should be quick and easy once he gets started.

He walked around the counter to greet you. I'd shake your hand, but I wouldn't want to get my grease on you or that pretty blue and white dress. You quickly think to yourself that you wouldn't mind his grease on a few things. It must still be nice outside it is he asks you. The weather is gorgeous you reply. Nice late summer weather.

You make an effort to look around and ask him where is everyone else. They went home for the day he replies. You are the last appointment for today. He walks over to the door you just came in and flipped the 'open' sign over. Would you go drive it into bay #1? I'll open it from the inside while you go get your vehicle.

You nod and exit the door to get your car. He locks the door behind you and walks to the back. You get into the car and have a quick think to yourself. Time for a little fun maybe. You and Mike always had a little heat between you, maybe you can turn that up a bit. You unbutton the top button of your dress, and slide your underwear off. Dresses are great for easy access. Flipping your underwear off the end of your foot you think to yourself, you never know, right?

Starting the car you drive around back to bay #1. Mike is there to greet you and direct you to where he wants you to park. Driving it in and stopping where he wants, you turn the engine off. Making sure to slide your now discarded underwear under the car seat where he cant see them, take out the keys, and exit.

You make sure you slide your long legs tantalizingly slow from behind the door. He pretends not to see, but you can tell that even though his head is pointing one way, his eyes are directed towards you. Your high heels catch all the guys eyes, adding to your nice long legs, most men will follow that path all the way to heaven as your husband says.

You grab your purse from the passengers side, keeping your legs as straight as you can, puffing your hips up a notch. I bet he can almost see the edge of your ass from where he is standing. If only he was standing behind you.

You grab your phone from inside the purse. Have to ask David if it is ok if you try to 'grab' Mikes attention. A quick note to him says "Might stay a bit later, see if I can get a discount", and you hit the send button. Waiting for David's reply before you decide if you should go further. David knew of the crush Mike had on you, and he knows you have a little flame for Mike. Getting his permission is always the first step, and makes for some awesome sex later once you get David alone. For now, its fun to tease.

As you walk towards Mike, who is operating the lift from the front of the car bay. You slip your phone back into your purse, but make an effort to have you drop your purse. Going to have to bend over to pick it up. You kneel down, careful not to let your knees touch the floor, and bend over slightly towards Mike to pick it up. Your dress showing your overflowing breasts. This dress was excellent for getting the attention of men. Large tits didn't hurt either.

You look up quickly and catch his eyes looking back at you. He moved his head so quickly you thought he might catch whiplash. You smirk and ask him if he saw anything he liked. Mike gives his chin a scratch and just smiles. A large long smile. You walk over to where he is standing. He is slowly elevating your car. You phone text message beep goes off. You reach into your purse to get it, and all it reads is "Go for it". God you love your husband. You're going to have to set up a good three-way tongue bath for him over the weekend to say thank you.

Mike asks if you can sit over at some chairs he is pointing at, so he can get your car maintenance started. You nod and walk over. Crossing your legs once you sit down, you grab your phone. Looking busy, you give the odd pose to expose. Moving your dress here and there. Rubbing in erotic zones. While Mike is working, you do your best to get his attention without saying a word. At one point, you just so happened to pull your dress down a little low, darn purse strap always catching on things, and you hear a loud clang! You look up and see Mike bending over to pick up something he just dropped. You notice he is pointing his hips away from you. It wasn't a natural movement, and was he blushing?

You ask him if it is warm in here and he grins at you and replies that it has been since you walked in the door. You smile at him and ask if there is anything you can do to help. As he walks over to you, you notice the bulge in his pants, and draws a line on your skin with his finger. From your neck, to the edge of your dress. He asks how that makes you feel? The contrast from your white skin to his freshly made black mark. You grab him by the back of the head and push your mouth onto his.

He is dirty. Grimy. From a long day at work. You kiss him long and deep. You explore his mouth with your tongue. You don't feel anything other than his mouth. He hasn't touched you yet. You can tell he is holding back, not wanting to get his dirt on you. You grab his hand with yours, pull down your dress to expose one of your breasts and put his hand directly over it. He groans and grabs your tit tight. Now you feel his hand on the back of your head, pushing you into his mouth harder as the grip he has on your tit tightens.

His breathing gets faster. His lust being unleashed. You wonder how long has he wanted your body. Your hands roam to between his legs. He is rock hard. You move your hands around him and haul him closer. To press his member into your body. You feel his shaft, hard and rigid, sticking into you. The thinness of your dress doing little to interfere with the sensations.

You pull away to look into his brown eyes. He cheeks are very red. His breathing elevated. You look down at your dress. Black streaks appearing here and there. Your bosom has grimy hand prints covering it. You whisper "Fuck me".

Turning around, you bend over and lift your dress up to show Mike your exposed bottom. No underwear. Just gorgeous ass and pussy. Wet with excitement. He wastes no time. You hear the zipper of his work suit drawn down. He whistles as you feel his hand on your ass. Appreciating the curves. Appreciating the opportunity.

You feel his hard warm cock between your ass cheeks. He grinds himself on you, moving back and forth with his hands on either side of your hips. Your arms resting on the chair, you feel his weight pressing onto you. He parts your legs a little further, you hear him spit and feel it dripping between your ass and across your pussy.

Then you feel him enter. You hairless pussy offering no resistance to the large cock sliding between your legs. He groans again. Letting himself sit inside you. He pulls you back at your hips with his grimy hands. Pushing him as far into you as he can. You feel his balls resting against your clit.

He pulls the rest of your dress down, exposing both your tits. One covered in his work, the other white and pure. You know by the end, both are going to be covered in Mike. He gives your back a kiss. Still holding his hard member inside you. Feeling his finger trace across your back, you think you will have to get David to take pics once you get home. Evidence of the time you fucked your filthy mechanic. You feel his large hand on your shoulder, another on your ass. He starts to move his hips.

Slowly at first. Every inch drawing more and more out of you. Each thrust is ecstasy. Mike is finally fucking you. You have wanted this for a long while. Feeling his manhood pounding your tight pussy. He grabs your tits while giving it good to your mound. He is trying to shove his cock through you with each thrust. Each pounding thrust bringing you closer to orgasm.

Fucking you harder and harder. Your pussy tightens. You feel that familiar feeling. Starting at your toes, working its way up your legs. His cock is relentless. Like a fast pounding metronome. You feel his dirty hands move from one of your tits towards your neck. He grabs you around the throat hard. You start feeling light headed. Your air restricted. Your orgasm building faster now. So fucking hot.

He grabs you by the hair, pulling your head back as he pierces you deeply. His other hand tight around your throat. Each thrust slapping his balls against your clit. Each thrust making a slapping sound as his hip beats against your bare ass.

Your dress is a mess, hanging loosely around your waist. It flows with each deep thrust. Each pounding deep thrust. Climax building. You are starting to go weak at the legs from overload. He keeps one hand on your throat, and holds you up by the waist with his other. Using your pussy as his personal milking machine. He moves your body in sync with his own to maximize each penetration. His body leaning into you and the chair. You feel his weight pressing down on you.

Then you hear him whisper, "I'm going to cum in you", and with that his cock explodes. His hands tightening around your throat. Feeling that last thrust was what you needed, and your pussy also explodes into orgasm. His cock drawing out each pulse from your love mound. You both groan as you continue to finish each other off.

You feel his grip weaken as the last of his juice empties into you. Your cum mixing with his. You decide to give him one last treat. You push yourself from him, turn around, and go to your knees. Time to show Mike how well you clean a pipe. You shove his cock into your mouth. Tasting both of your cum. You lick up and down his shaft. Tasting up any spots you might have missed. Your pussy still pulsating from the pounding and orgasm. You feel him slowly leaking down the inside of your leg. After your sex cleanup treat is done, you kiss his cock on the head and stand up.

He looks exhausted. It appears you took the last of his energy out of him. You joke to him that he can still get the job done right? He smiles at you and tells you yes, with his eyes closed. He picks up his clothes from around his ankles and zips himself up. As he walks back to your car, you ask where the bathroom is. Smiling to yourself, this is the first time you have ever had to use it here.

Bringing your purse, you walk into the bathroom and get a good look at yourself. Covered in black marks, from your neck down. Your dress looks like a crumpled mess of blue, white and black. Good thing you don't have to walk home. You take a couple of pics to remember the moment. The marks on your tits and neck are really obvious, and you suspect your back is also covered. David is going to love hearing about this. You really must work something out for him for being such an awesome and open husband.
