Chapter 1: A New Deal

“That’s it, take it all” I groaned pushing down the head in my lap.

The blond girl gagged and made a choking sound as my cock pushed against the back of her throat.

“I know you can take it slut. Open that wet little throat” I groaned pushing harder.

She gagged again as I forced the head of my cock down her throat. I groaned loudly as the wet constrictions of her throat massaged my cock as she swallowed. I wrapped her hair tightly around my fist as I fucked her throat with fast short strokes.

I released her and let her slide off my cock. A thick stream of spit ran down her chin as my cock slid past her lips. She coughed a few times while her hand took over stroking my cock. She broke the heavy strands of spit connecting her lips to my cock stroking them into my shaft.

“Breaks over,” I said yanking her down my cock pulling painfully on her hair.

She screamed a little around my cock which let me shove my cock straight back down her throat.

“That shut you up didn’t it, bitch” I groaned.

I held her down on my cock, her lips spread wide around the base. Her nose pressed against my stomach my balls pressed against her chin.

“Fuck that’s good” I grunted.

Her throat was jerking and convulsing around my cock as she started to struggle to breathe. Her small fists thumped against my thighs as she tried to pull away. I kept her pinned for another few seconds before releasing her.

She pulled back off my cock gasping for breath. I quickly jerked my cock and unloaded on her face. My first heavy steam painted a thick line from her left jawline up to her face and tagged her hair. The second and third hitting both cheeks, the right side shot sealing one eye shut.

I landed a fourth rope right into her gasping mouth. I shoved the head of my cock past her lips and jerked the last of my load onto her tongue. She glared at me with her one open eye but still dutifully swallowed then licked the head of my cock clean.

“Fuck sis, you sure are a good little cock sucker,” I said as she rose from between my legs.

“Urghh, it’s in my fucking hair,” she said angrily.

She grabbed a tissue from the nearby coffee table and wiped the jizz that had kept her right eye shut.

“It was an accident,” I said offhandedly with a shrug.

Her face was a mess of cum, smeared make-up, and spit. Her hair was messy from my rough handling and wayward cumshot. Her simple blue baby tee was wet as a result of her sloppy deep throat and cum dripping from her face.

“You such as arsehole” she accused as she stormed off.

I used the same box of tissues to clean myself up then grabbed a coke from the fridge. I sat back down in the lounge with a sigh and restarted the film I had been watching before my sister walked in.

She came back downstairs about half an hour later. She had washed her hair and pulled it into a French plait she wore over one shoulder. Her blond hair still slightly damp from her quick shower. She wore a loose vest she half rolled up and tied into a knot leaving her midriff bare. The loose neck of the vest and straps tied around her neck showed she was wearing a pink bikini underneath.

A pair of daisy duke shorts so small the pockets could be seen hanging below the hem of each leg sat tight around her waist. Smooth and slender legs left bare, her dainty feet in a pair of flip-flops. A pair of sunglasses sat on top of her head, a beach bag hanging off her left arm.

Short at 5’2”, she had a flat stomach and tiny waist with a compact but cute little butt. Despite her slender build, she had a nice round set of C cups that filled out her bikini very nicely. With her bright blue eyes and natural blond hair, she looked every part a beach babe.

I probably shouldn’t be checking out my 16-year-old sister, and I certainly shouldn’t have her sucking my cock on a regular basis. Our relationship wasn’t exactly what you call conventional.

“Keys” she demanded thrusting out her hand.

I sighed and fished my keys out of my pocket. I threw them to her purposefully making sure they flew over her head. With another sneer, she turned and bent over and picked up the keys giving me a great view of her ass.

“Make sure you fill it back up” I shouted as she left.

She didn’t bother answering.

My little sister, Lori, had passed her test when she turned 16, six months ago. With no car of her own and no job to pay for one, she was constantly asking to borrow my pick-up.

I had worked hard to pay for my truck. It wasn’t anything special, just an older model Ford pick-up but it did the job. Mom was a single parent as dad had run off with a 20 someone blond not long after Lori was born. He and my mom only got married because he managed to knock my mum up with me when she was 16.

Mom was a nurse and worked almost every day for 12-13 hours just to make ends meet. The poor excuse of a man I called my father had left her with mortgage payments and debts she barely managed to pay. There’s was nothing in the budget for cars or college funds.

When I was 15, I went door to door offering to clean pools, wash cars, mow lawns, and do just about anything to earn a buck. Living in Cali meant lots of people had pools and I focused on the richer neighbourhoods. By the time I got to 16, I had a decent number of regular customers and managed to buy my first truck. It let me expand and improve my services.

Pools cleaning and maintenance was my main course of income. I also did other small maintenance and handyman jobs, with the occasional bit of painting and decorating. I had also quickly discovered a way to almost double my earnings with tips.

It turned out that the rich trophy wives who paid me to clean their pools almost always felt neglected by their power broker and corporate lawyer husbands. They always flirted shamelessly with me especially when I worked with my top off. It didn’t take much to start servicing them as well as their pools and they always tipped generously afterward.

I had actually gained a few customers that way after a couple of them told their friends. It was all very low key as they were all married and until 3 months ago, I was underage.

That, however, is another story altogether. The point is, I had a steady stream of business that let me afford a truck and help out mom every month.

The first time I let my sister borrow my truck, she brought it back with a smashed rear brake light. One that I had to pay to fix. She had begged me for another chance and even tried to get mom to weigh in. She just told my sister to get a job and left it at that.

About 2 weeks after that first time, she borrowed my truck, and a month after she passed her test, she came to my room begging to use my car.

“Please, please, please bro” she begged her bright baby blue eyes big and bright.

“No,” I told her simply while focusing on my game of CoD.

“Please! I’ll promise I’ll be careful” she begged.

“And I really need to go to the mall” she protested as if that would change my mind.

I died in-game and was getting pissed off with her constant pestering.

“Please ... I’ll do anything” she begged bouncing up and down like a petulant child.

“The only things I want are money and sex. You can’t give me either” I said dismissively while re-entering my game.

“Okay,” she said after a short pause.

“Okay, what,” I said not really paying much attention to her my focus on the T.V.

“I’ll give you ... that,” she said.

I scoffed.

“Yeah, like you have any cash,” I said thinking that’s what she must mean.

“No. I mean the other thing. The ... The sex bit” she said quickly.

I looked at her suspiciously while I died in-game again. It felt like a trick. In the words of Admiral Ackbar “It’s a trap!”

She looked nervous but cute as she blushed and bit her lip bottom lip.

“Just so we’re on the same page, you’re saying I can fuck you if I let you borrow the car?” I asked still sure I had mistaken what she meant.

Most brothers probably don’t fantasise about fucking their sister. I guess I wasn’t the average guy. My sister was hot. The was no two ways about it. Like any guy, I wanted to fuck hot girls. For me, the fact she was my sister didn’t really factor into it.

“No, no...” she started and I actually felt a little disappointed but not surprised.

“But I’ll jerk you off” she finished quickly, blushing even harder.

My heart beat fast in my chest. I had to play this cool. Act like I was doing her a favour by letting her effectively be a whore for me to use my truck.

“A hand job ... please, I can do that myself,” I said trying to act as nonchalant as could.

I held her gaze and could almost see the indecision in her eyes.

“A blow job then,” she said quickly.

The words almost fell from her lips like she hadn’t actually meant to say it.

I was already growing hard in anticipation but tried to keep a lid on it and act cool.

“A blowjob and you swallow my cum” I countered.

I was getting laid regularly at work, but Lori was 16 rather than 36. Plus, they rarely gave me a blowjob as I was the one being paid to please them. Then there was the added taboo nature, which was a real turn on for me. She seemed on the edge of indecision then nodded. I could hardly believe it.

That first time was nothing like it was now. I let her be in control and apart from the occasional muttered curse and a stammered warning of my climax I stayed silent. I felt like if I made too much noise or touched her, she might suddenly change her mind.

I knew she had a couple of boyfriends before but wasn’t sure if she was a virgin or not. It was obvious; however, she had sucked cock before and didn’t gag or spit when I came in her mouth.

She left quickly after I gave her the keys and avoided me when she got back that night. She avoided me for the next few days hardly coming out of her room. I thought that was it. A one-off that would only be repeated in my fantasies.

Then, nearly a week later, she had come back into my room again, and then again, and again and again. For the past 5 months, she was on her knees twice a week swallowing my jizz to borrow my truck. After the initial novelty of having my sister sucking my cock, I started to become more dominant and controlling.

She protested but had no real conviction to her voice. She might not openly admit it but I felt she was a natural submissive and enjoyed the rougher treatment. Whatever her reasons, she still kept coming back for more.

Most of the time she wanted to use my truck, I actually had no intention of using it myself. But she didn’t need to know that. I occasionally refused her and used the truck myself even though I hadn’t planned to. It was just often enough to make it appear I was doing her the favour.

Friday afternoon, 3 days after my last blowjob, when Lori had gone to the beach, I was relaxing on the sofa. I had just finished a week of extra work so I would have the weekend free. Kristy, a super hottie daughter of one of my clients, had invited me to spend the weekend with her at her parent’s cabin.

She was just a year older than me and absolutely stunning. She had been the older girl at school all the guys dreamed about. Head cheerleader, loaded parents, and popular. Smart as well. Although she looked like the stereotypical blond bimbo, she was actually valedictorian for her graduation and had a full scholarship offer from a number of ivy league colleges.

Plus, we all heard the rumours of her promiscuity. Apparently, she was quite the nympho, if even half the stories I heard were true, I was in for a wild weekend that would leave me with a permanent grin.

With summer break having started a few weeks ago, she was staying with her parents for a few weeks before her second year. With her sunbathing in her garden while I worked, we got chatting. She was as much a flirt as you would expect.

So, when she had suggested we spent Friday evening to Monday morning alone at her private cabin, well, you can guess where my mind went. Obviously, I agreed and had spent the week making sure all the jobs I would have normally done at the weekend, were finished during the week.

Today hadn’t been too busy, I wanted to make sure I was rested for Kristy. Just 2 routine pool cleanings and a little light gardening.

“Mom home?” Lori asked walking into the lounge.

“Extra shift at work. Won’t be home till ten” I replied not paying her much attention.

If I had been paying more attention, I might have noticed she had that look in her eyes I had come to recognize. That, “I need the truck so drop your trousers” kind of look.

I didn’t notice until she suddenly appeared between my legs and started tugging at my shorts. She didn’t try and just ask for the keys or even say anything. Just pulled my shorts off and started to suck my cock.

Obviously, I didn’t protest but just relaxed into it as my cock quickly hardened in her mouth. It felt like she was in a hurry as she quickly took me into her throat with minimal gagging. Usually, I had to coerce and force her down.

I had barely reached full hardness when she closed her eyes and forced my cock down her throat. She made her throat ripple as she swallowed and used one hand to play with my balls how she knows I enjoy.

She pulled back to take a quick breath briefly jerking me off instead. Her lips parted over my cock again and she bobbed her head with a twisting motion while her tongue swirled around the head.

Lori had improved a lot since that first time, but she wasn’t always an overly enthusiastic partner. She just kind of let me use her mouth and throat as a means to an end. Today she was very much an active participant and using every trick she had to bring me off.

It was an interesting and much-appreciated change even if a little curious. I held off as long as I could, savouring her new attitude towards our little arrangement. But, with working so hard all week I hadn’t had time to offer my extra services so was pretty backed up.

I was planning on Kristy draining me later tonight, but maybe dropping a load and taking the edge off now was a good idea. Didn’t want her to think I was a two-pump chump when I finally fucked her later.

When I did grunt a warning to Lori, she surprised me again by taking me back down her throat and letting me cum straight into her stomach.

“Holy fuck, sis. You’re an eager little cum slut today” I said expecting her normally snarky insult in return.

Instead, she was surprisingly subdued. Polite even.

“Keys please,” she said holding out her hand.

Without the distraction of her providing the best blow job she has given me yet, I noticed she was dressed differently from normal. Gone were the normally skimpy outfits she wore that I’m positive she wore just to tease me. Instead, she wore a normal, full-length pair of jeans and a loose-fitting wool pullover.

Very conservative for her. Very out of character.

“Nope. Sorry” I said pulling up my shorts.

“Stop playing,” she said.

“I’m not. I’m going away for the weekend. I need them” I replied.

“But I sucked your cock. That’s the deal” she protested getting angry.

“Normally it is. You always ask for the keys first, I tell you that you know the price. You blow me, you get the keys” I told her.

“And” she replied looking at me with a ‘so what gives’ expression.

“Today you never asked if the truck was free. You just came in and sucked my cock. Great job by the way. That was awesome” I said aiming for sincerity but coming off slightly patronizing.

“You utter arsehole” she shrieked now properly angry.

“We have a deal, give me the keys” she demanded stalking towards me as if to take them by force.

“Hell no,” I said as I easily held her off.

Her petite 5’2” was no match for my muscular 6’2”.

“I’ve got a whole weekend with Kristy Hall, and I ain’t gonna miss it just so you can go to the beach or whatever it is you do.”

I had her arms pinned behind her back and legs locked.

“You’re seeing that slut? You know she let the entire football team fuck her ass because they won the championship.” She said after I released her and pushed her away.

“Why do you think I’m spending the weekend with her” I replied as if it was obvious.

Lori looked almost frantic with need. Her cute 16-year-old face looking more worried that I had seen it before.

“Can’t you go in the morning instead? Let me have the car today?” she begged.

“And miss a night of mind-blowing sex? Hard pass,” I told her.

She screeched in fury, launched a pillow at me, and stormed off. I hear her pounding up the stairs then slamming her door.

“Crazy bitch.”

About 45 minutes later I was in my room finishing up packing my bag. A light knock on my door and Lori slipped in closing the door behind her. She usually only came into my room if she was going to blow me, but I didn’t think she was going to do that again. What did surprise me was that she had changed. Now she just wore her thick cotton bathrobe.

“What?” I asked a little sharply not prepared to argue again.

“I really need that truck and...” she started to say before I cut her off.

“The answer’s no. I’ve already said that I’m not giving up some premium ass no matter how good the blowjob was”.

“I know,” she said then dropped her bathrobe.

I’m pretty sure my mouth actually dropped. My little sister was completely naked underneath. In all the times she had sucked my cock, she had never actually shown me her body. I had asked but she always refused. I never understood it. Suck my cock and swallow my cum sure, but showing her tits? That was a line she wouldn’t cross.
