Alone at work (A fantasy)

It's a slow day at work, I'm the only one scheduled for the day. A compact car pulls in, I come out to greet and I'm greeted by a gorgeous body in a short sweater dress. Engine is making a funny noise she says, so I pull the car into the bay, fill out the paperwork, pop the hood and begin the hunt for the noise. There's a slight tapping, so I call her over to the front of the car, hood up, and ask if its the sound that she's heard. She says she can't hear it, so she leans in closer, the sweater dress can't contain the gorgeous ass and rides up. I'm staring at the tiny thong hidden between the massive cheeks. She looks back and catches me staring. I turn bright red and apologize profusely. I'm ready to get yelled at by a client, but she just smiles and says "go ahead, get a better look" as she hikes up the dress a bit more and bends over, hands on the front bumper of the car. It's such a beautiful ass!

She takes her hands and spreads her cheeks, my eyes are fixed on the lump forming in the front of her thong. She seems me staring and pulls aside the front of the thong and her cock falls out. It's a beautiful small uncut cock. I can see her pouty asshole, her perfectly hairless balls and small cock swinging. I'm enamored, without asking I put my hands on her ass, she lets out a slight moan and pops her ass up a bit. This is the invitation I was looking for. My tongue darts out of my mouth and slowly makes circles around her asshole, her hands spreading her cheeks I start to slide my tongue inside. At this point, she's moaning, enjoying her ass being penetrated by my wet tongue. As I'm tongue fucking her, I notice her cock starting to drip pre-cum, so with one hand I reach up and start to stroke it, the other hand starts to massage her balls, and my tongue continues to invade her.

Now she's moaning and grabbing her tits, pulling her dress up revealing that she wasn't wearing a bra, or anything else for that matter, beneath the dress. My cock is at full attention, also prelubricated with my own pre-cum. I pull it out of my pants, stand up behind her and slowly guide the head of my swollen cock into her ass. She's biting her lip as I struggle to get the head in, not for lack of lubrication, but because of how tight she is. A little patience and a lot of work, the head pops in, the rest of the shaft seemingly sucked in right behind it. We both let out a moan as our bodies spoon....

Unfortunately, we never really figured out what was wrong with her car, but we definitely tried to identify the problem several times after that ;)
