Jealousy Ch 01

"Fuck me harder, Nick," Sarah urged between moans, as she gripped on to the headboard. I heard her command loud and clear, and somehow managed doubled the speed of my thrusts as well as giving her ass an occasional slap for good measure. I could feel my orgasm building, and it seemed Sarah had sensed it too.

"Hold on, I'm so close," she begged. Sarah's large, curvaceous ass jiggled with each hit; her D-cup tits were doing the same, I imagined- I couldn't see them from my vantage point. She had put her dark brown, shoulder length hair into a short pony tail that draped across her bare back and reached out one hand from her hip to grab it. Pulling back sharply, a squeal of perverse pleasure escaped Sarah's lips. After fucking each other for this long, I knew how she liked it. Rough.

"Cum for me," I said, leaving out the 'bitch' that would have more often than not been there had we been roleplaying Master/Mistress- one of our favourites.

That seemed to do the trick. After a few more thrusts from me, "I'm cumming, I'm cum..." her words trailed away as she was taken over by the waves of her orgasm. That was all the permission I needed. I relaxed my pelvis, firmly gripped her hips again and pulled her into me more than I pushed into her. Sarah's orgasm must have been good, because it was like fucking a rag doll- she had no control of her limbs. It only took about ten more thrusts for my load to coat her pussy. I grunted in pleasure as I did, that was one of the best orgasms I had experienced in a long time.

Eventually, after what seemed like an age, I pulled out, my cock dripping. Sarah was half still in the position, half collapsed on the bed, but on feeling me pull out she rolled over on to her back. Her heavy breathing caused her tits to rise and fall a great deal, and this only made her flat, muscled stomach look even better. I was still kneeling, giving me a great view of her young, nubile body. Her face was a picture of beauty, and her make-up was always perfect- not that she needed it. She was naturally white skinned but always had a tan, which was a perfect constant all over her body thanks to sunbathing naked on the beach and in the yard. The only break in this was the baby pink of her areolas, that framed her cute and small nipples that were hard enough to cut glass after that. Her tiny waist and washboard stomach afforded her an hour glass figure, and made her hips stand out.

She had a sliver of pubic hair, in the form of a central strip. Sarah's pussy was one of the only ones I had ever seen that I actually found attractive rather than ugly. Her toned, slim frame (she lived in the gym), meant it did not stick out and the lips were not protruding either. Many thought her long legs with perfect thigh gap were her stand out feature, but they weren't lucky enough to have seen the rest of her. I sometimes wondered how I was related to such a goddess. Though, with my tall and muscular figure, cut jawline and, according to Sarah, the best ass on any guy she had ever seen, I guess I was not too bad looking either.

I collapsed on the bed next to my sister, and realised I was still panting a little bit too.

"That good for you?" I asked jokingly, clearly already knowing the answer.

"Average, I've had better," Sarah giggled.

"Tell that to my cock, he's drowned in your juices."

"Oh, really?"

Sarah rolled over so she was on top of me, her breasts suffocating me in the nicest way possible. That would be a good way to go, I thought. She slid down my body, her dripping pussy leaving a trail of bodily fluids as she went. Without warning, her mouth enveloped my tender cock, forcing a deep intake of breath. I felt my member growing with each passing second, as it was comforted by the warmth of her mouth. My sister gave the best head, not that I would tell her that for the sake of keeping her ego small enough to get through the door; my cock clearly was not aware of the plan and grew to its full size within the minute, despite having just cum.

"Looks like someone wants a round two," Sarah noted, taking my cock out of her mouth for a second so she could speak. Yes, it was that big.

"Mom and Dad will be home any minute," I warned.

"The shower it is then, I'll meet you in there," my sister said, and with one last suck she jumped up and headed for the door. I watched her ass jiggle as her hips sashayed their way out of view. Still at full mast, I did the same and headed towards my en-suite bathroom and got in to the large, walk-in shower. I knew where she was going, this was a tried and tested system: first, she would turn her shower on and put some music on that would be too loud for their parents to shout over. Then Sarah would lock the door from the outside using a coin on the safety lock, and come and join me in my shower so I could fuck the shit out of her without our innocent, church going parents knowing.

Her absence gave me a few moments to reflect how we had got ourselves into this. Sarah was the older of the two us, at 21 compared to my 19. Many moons ago, I had a date. I had never been on a date before, and I was nervous as hell. What would I say? What would I do? What if she wanted to kiss me? So, I turned to the most sexually experienced person I knew: Sarah. She had a reputation at school for being, well, promiscuous shall we say; in actual fact, it meant she had fucked half of her grade and half of the grade above. Okay, maybe that was an exaggeration, but her number was high. No wonder, looking at her; every guy would have given their right arm to even speak to her, never mind fuck her. My friends used to tease me about jerking off to her Instagram page. Even I thought she was hot, as weird as that was. She was the queen bee, the head cheerleader, the whole shebang.

Meanwhile, little, old, sickly me was stuck at home half the time. I had Crohn's disease (google it), which meant my attendance record was below 50%. Luckily, I was a bright kid and still managed to maintain my position at the top of the class. Unfortunately, the same could not be said for my dating life. Socially I was fine, loads of friends, hung out with them a lot, but girls were a different ball game. I mean, I didn't struggle when talking to them, it was more getting the chance to when I was hardly at school. Equally, shitting yourself (thanks, Crohn's) was not all that sexy.

So, when I started speaking to this girl called Emily, who was of Chinese heritage and was simply stunning, I wasn't going to mess it up and asked Sarah for advice. She coached me, on what to say, what to wear, how to act. Then I asked her how to kiss; I thought she was going to explain. However, it turns out my sister was a more 'lips on' kind of teacher. She planted them on me, and told me to kiss back. Surprised, I did and she had me make little adjustments as we went. By the end of it, I was hard which made me blush and feel sick at the same time. I admonished her, saying she's my sister. Sarah told me to loosen up, no one would know and it was none of their damn business (which happened to be our motto since.

That was just the start, though. I went on the date, got the kiss (which Emily said was the best first kiss she had ever had, thanks sis) and secured a second date. On said date, I reached a new milestone: cumming without having anything to do it myself. We were making out, I naturally got hard, Emily noticed and jerked me off in the parking lot of a Taco Bell. After we had cleaned up, she said she had to get back not to break her curfew but that I could return the favour next time. This made me ice run cold, I had no idea what she meant, never mind what to do. Once again, I turned to my relationship-cum-sex coach (pun intended) and asked her. She informed me Emily wanted me to finger her, preferably to orgasm. Naively, I expected an explanation or a diagram, instead I found my fingers three inches deep in my sister's pussy.

And so, it went on. Each week there would be a new, alien sex act and my sister would show me the ropes. Emily was my first everything, all the way up to sex- or rather, was she my second everything? The first time I fucked Sarah, following her instructions, much to everyone's surprise she orgasmed. Little old virgin me had made my slut of a sister orgasm. I mean, we had practised oral and it was the third round after I came in 12 second the first time, but I still made her cum. After that, the 'demonstrations' became a bit more regular and my slutty sister became a lot less slutty now she had access to sex on tap at home. Emily and I broke up after around six months, with her citing the feeling another woman was involved (little did she know), but Sarah and I carried on. In fact, neither of us had dated anyone else since then; my health had deteriorated which meant I didn't get out as much, though had recently improved, and Sarah had just started a modelling career that she was focused on (which meant trying not to fuck a colleague and get fired). We settled into our routine, and each other, satisfied that this particular need was taken care for. The romantic stuff, with other people, could come later.

My thoughts were cut short by Sarah's arrival. Her full body was breath taking, not an ounce of fat or cellulite. Her nipples were still hard enough to cut diamonds. For a brief second, I thought I could see her pussy glistening with wetness. Sarah walked into the shower, and pushed me up against the far wall. I was fairly tall and Sarah's height meant she only came up to just below my shoulders. We always joked that with her height and the length of my cock, she wouldn't even need to kneel down to suck me off. Apparently, she wasn't taking note of that today. Her knees made contact with the grey slate tiles that lined the floor, and water gushed over her head.

"He seemed to enjoy being in my mouth before," Sarah said, referring to my cock. "And he was such a good boy waiting for me to cum, that I think he deserves a treat."

With one fell swoop, she took my whole length in her mouth which was no mean feat. Now, don't think she was just being nice with that comment. I mean, she was but she had her ulterior motives. Namely, she knows I'll lick her out first thing the next time we do anything and also, she loves giving head. I don't know whether it is the power of it, or knowing I'm so pleasured but it turns her on. So much so, knowing I'll be spent, she will go from sucking me off to her room, whip her plethora of sex toys out and orgasm again. If you hadn't already worked it out, she was insatiable; to the point I wondered whether she had some form of sex addiction. It was a bad day for her if she didn't cum at least twice.

My head snapped back to the present as the pleasure began to build, not that it took long with Sarah. On the surface, it didn't look like she was doing much what with her head only moving forward and back very slowly, but inside her tongue was hard at work; much like a duck: serene above the water, but their little legs were working like hell underneath.

She really was the queen of blowjobs. Little surprise, considering the number of guys she had sucked off under the bleachers. She would rival most pornstars for the World Record of 'Most Cocks in Mouth'. My sister must have done this to me a hundred times, but it never got old. Even now, I was gripping her hair tightly with one hand and steadying myself with the other.

Now, she went in for the kill, and deepthroated me with the skill of a master. She sped up her head movements, and I gave her a hand by pushing her head down aggressively- something I knew she liked. My orgasm was building for the second time today, and I released a grunt.

"It's so good, sis." I praised, to which I got a muffled reply which I assumed was her saying, 'I know'.

When she got her hand involved, I knew it was over. She twisted and stroked my shaft, all while continuing to suck me off as she had been doing. It took twenty more seconds for me to shoot my full load, or what was left of it after round one. At least eight strings of cum coated my dirty sister's mouth. Sarah swallowed it eagerly. A little drop escaped her perfect, plump lips and dripped onto her left tit. As she bent down, and sexily licked the offending cum off her body, I thought I was going to cum again right then.

Sarah stood, gave me a kiss, and a cheeky slap on the arse as she wrapped her arms around my waist and said, "Same again tomorrow, bro?"

This was sort of their in-joke, whenever they made the other one cum and they had finished that particular session. The answer was always yes, because they had fucked literally every night (and a lot of days) for goodness knows how long. Even if one was out, they tended to do something when they were back.

"I can't tomorrow," I said nonchalantly.

"Why?" Sarah said.

"Erm, I have a date."

"A date? Who the fuck do you have a date with?" Sarah scoffed, but was clearly slightly jealous.

"Leah Hartley," I replied, preparing for the backlash. She was a family friend, and Sarah and her had been very close for years, drifting apart only recently.

"How?"

"How what?"

"How was it arranged, did you ask her or what?"

"No Mom and her mom set us up," I explained. "Mom wanted me to get out there, and her mom wanted her to stop fucking around basically and settle down with 'a nice young man'."

"Well, I'm happy for you, Nice Young Man," Sarah said unconvincingly, as she exited the shower and made a cursory attempt to dry off. "I will buy my hat for the wedding."

With that, she left the bathroom, causing me to scrabble after her soaking wet and slipping over the tiles. I just caught a glimpse of her picking up her bra and panties, before she left the room and slammed the door.
