Show him you're a good girl

You nervously ask him what it will take and he says if you help him "release" some pent up stress he will be more inclined to be more negotiable. You weigh your options and between helping a guy get off and walking in the hot sun for some cash to get your car fixed one seems much easier than the other. You agree and he smiles happily "Good choice sweetie so how about you get down too it then and lube me up". You're shocked at first but then tell him a blowjob wasn't part of the deal and you want a discount. He sighs and shakes his head "fine we can discuss it later so how well you do will affect it, happy now?" he ask annoyed. You smile and tell him it sounds like a plan and squat down ready to get this over with. He smiles and pulls the zipper down his cover alls letting them drop to his ankles. "Well dont be shy sweetie you can take it from here" he says thrusting his hips a little leting you see the faint outline of his cock under his boxer briefs. You reach up and grab the waist band slowly pulling it down first you notice his trimmed pubes thats good hair can be so annoying. As you pull it down his semi erect cock hanging thereyou immediately notice a very musky scent coming from him, clearly hes been busy so it makes some sense. With a shaky hand you reach out and take hold at the shaft and you get a reaction right away. "Mmm that's it now give it a kiss" he instructs and you bring your lips to the head and give a quick kiss. His cock begins to harden up as you star to move your hand along the shaft to the head. He quickly grows to about 6 inches right infront of your face occasionally he throbs and you can hear his quiet grunts. Well it seems he's ready so you open your mouth and slide his head past your lips and you can taste his salty sweat...and its not that bad. Sure it isn't good but it definitely could be worse. So you begin to slide down his shaft till his balls tap your chin, then moving back keeping the head inside. You decide to keep your hand in front of your lips so you can jerk him while you suck him. Every so often you pull off him and angle his cock up so you can lick his balls or suck on them. After a few minutes of you slurping on his surprisingly tasty cock he tells you to stand up and you feel his hands undoing the zipper and button on your shorts, his hands linger for a moment till he grabs the waist and pulls it below your ass cheeks. He pushes your upper body foward onto the hood and you feel his hands spread your cheeks apart. You then feel his warm breath against your hole and suddenly a wet sensation of his toung going up your crack followed by him spitting onto your hole. "Mmm I wonder if your as smooth on the front as you are back here" he says standing up and giving your right cheek a firm smack and grabbing a handful of ass. You nervously laugh a little not sure if you're ready for what comes next.

Its time you feel his cock head pushing against your asshole trying to get in and you're kinda excited. "Alright baby im coming in so try and relax ok?" You nervously nod and you feel his grip on your hips tighten as your ass feels very hot. His cock begins sliding in stopping after the head giving you a moment to adjust before he continues. Slowly inch by inch his saliva covered shaft enters your ass causing it to hurt but also feel good. Your pussy is definitely betraying you hopefully he dosen't notice how much you're getting turned on by this. He finally makes it balls deep in you and you can't help but to moan. He laughs and smacks your ass again "That's is baby let me hear those slutty moans". He starts to spull out until he gets to the head and thrust back in. You try to keep your moaning down as your upper body is pushed against the hood by his increaseing thrust. He begins to pick up pace till he keeps a constant in and out motion. The garage is filled with the sounds of his grunts and your moans along with the sound of his wet balls slapping against you. This continues for about 4 minutes and he increases speedand you immediately know what that means. You decide now is a perfect time to negotiate that discount and look back at him "h-hey......mmm-mark.....ah-about...that....discount......" he looks at you straining to keep his composure "y-y-yeah....what...oh...fuck that tight...what...about....it" he ask pounding harder clearly getting close. "I want.... fuck t-thats the spot .....I w-want fifty....per.. oohh...per..cent..off...or oh..yeah thats it...or...i'm...gonna.....pull.....you....out and use...m-m-my...hands...instead... got.. it?" Mark was shocked "you can't.....ah shit....be..s-serious...." the look in you eyes told him all he needed to know "....f-fine...deal...now...shu..uh...fuck......im...so...close...s-shut...it....while.....I.....fill..this....tight..ass...ohhh..here. it..comes....bitch..." he gives both cheeks a hard slap and pulls you onto him shoving his cock as deep as it can go and you lose yourself in an orgasm feeling his throbbing cock and balls against your skin. You feel his cum inside yourself and there is quite a lot. You all but collapse when ge pulls out and he rubs his cock against your ass cheek leaving some cum behind "thanks sweetie that's just what I needed and clearly you too, but I'm a man of my word so when you can come pay what you owe" you groan and shakily stand up asking where the bathroom is. He points off into the office section and you head off not bothering to pull your shorts up. When you get in you drop off your shorts and squat over the toilet to try and clean up his jizz thats leaking out. After you feel mostly clean you get your shorts and panties to put back on....well shorts to put back on, your panties are pretty much soaked so they are a no go so you put them in your bag to throw in your car to clean later. After making sure your all set you get out and meet Mark who is finishing up and doing a quick check to make sure. You smile and thank him for his help and he thanks you for yours, and you pull out of the garage. Its almost noon so you can still make it to the mall or should you go home?
