Kevin sat in his room, with one hand down his pants stroking his semi hard cock, while using his other to navigate

. Kevin was an 18 year old senior and like most boys his age was seemingly always horny and quite curious. He had a girlfriend of over a year, one he cared for quite a bit. But that didn't slow down his desire to jerk off to porn, sometimes a few times a day. They started having sex a few months back, both being each other's first. But his girlfriend Mary was petite and didn't enjoy Kevin's 8 inch thick cock. She tried to give him a blow job a few times, but could barely manage to get past the head and so it usually turned into a hand job. And the sex he thought was good, but it had to start slow, their was never any quickies.
Kevin had heard of this site and had gotten curious enough about it that he spent $100 cash to buy a preloaded credit card in order to subscribe to someone's account. He might have been 18, but his parents still watched his account spending, so he figured this would cover his tracks. And sure, he could get plenty of porn for free, but the alure of amateur girls posting pictures and videos really got him excited. Even some of the hot girls at school had rumors going around that they had accounts on there, but Kevin doubted any of that. He created an account and punched in his card, loading the balance. Now it was time to find that hottie to subscribe to. He scrolled through different genres, miles, cougars, goth, even barely legal, although those girls only reminded him of his girlfriend, small and petite, although cute. He then clicked on the college girls tab. He was mesmerized in fantasy as he looked at the girls promo photos, imagining what he would be in for come college next fall. Their was plenty of blondes, Asians, some black chick's, but Kevin kept scrolling trying to find that perfect girl to spend his money on.
His jaw dropped. There she was. Kevin's older sister by 4 years, plain as day scantily clad.
"HOLY FUCK" Kevin muttered.
Kevin got teased quite a bit when they were both in school together and even now, once in a while the teasing would happen again. Kelley was hot. Their was no way around that. She had a nice curvy ass that could turn most heads, but she also had absolutely massive tits. Kevin swore they got bigger every time she came home from college. And of course his friends always ribbed him about her. They would always say they were joking, but he also knew damn well that anyone of them would hook up with her given the chance to.
Damn was he surprised. She never acted or dressed slutty by any means. He only knew of one or two boyfriends and her clothes were never overly revealing. But their she was, the same fine smiling sister he knew, with brunette hair and her massive tits. Except now they were spilling out of a bikini top that was intentionally too small. Kevin's cock grew harder as he continued to stroke it. Her profile read:
Busty college coed with natural 32hh tits and a nice ass, offering you plenty of pics and videos teasing you with miles of curves!
"Damn" Kevin muttered. He shook his head in surprise, both at his sister apparently doing porn and at himself for being aroused by it. He knew it was wrong, but he kept stroking, imagining what she looked like nude, those giant, soft tits bouncing around. It wasn't long before he let out a soft moan and unloaded his balls into his boxers. Post-nut clarity sunk in and as he washed up, Kevin felt a bit guilty and disgusted with himself. He felt like he violated his sisters privacy on top of masturbating to her picture.
He went down to dinner shortly after and all while he helped with cleaning up, he kept having to readjust his hard cock into the waistband of his shorts to try and keep his parents or younger sister from seeing his pitched tent. The thoughts kept racing through his mind about his sister, which kept him constantly erect. Kevin kept trying to push the thoughts away, but they pushed right back in. The rest of the evening and night was spent trying to fight those sultry thoughts of his sister. He sat there in bed, unable to fall asleep with wild incestuous thoughts and a raging hard on. He rolled his eyes in surrender, got up and grabbed his laptop. Kevin logged on and scrolled through the site until he found that familiar smiling girl, the one he loved and cared for like a sister, well, because she was.
"Dad always said we should support each other" Kevin whispered to himself as he clicked 'yes' to the 3 month bundle, emptying nearly the entire balance of his

account. He rolled his eyes at his own little joke.
Kevin put his headphones in, slid down his shorts and started jerking off while watching his big sister's welcome video. She said her welcome and thank you for supporting her with enthusiasm as she bounced up and down causing her massive tits to bounce, nearly popping out of the lavender lace bra she was wearing.
"I hope I can help you cum again and again!" his sister said with a wink as she moved her hand towards the front clip of her bra. Steve was furiously stroking himself at this point. His heart was tense with anticipation as she unclasped her bra and her tits pushed their way out and into the open. Kevin's jaw hit the ground once again.
"Jesus fuck" Kevin muttered with a grunt as he kept stroking. She massaged her tits, circling her fingers around her huge areolas and perked up nipples. He could here her giggle and moan as she teased herself and her audience. Kevin let out a grunt as he shot a huge load of cum all over his chest and stomach. He laid there in amazement, still in awe at what he just watched. It was better than any porn he had seen. One short teaser of a video and Kevin was hooked.
Over the course of the next two weeks, Kevin jerked off on average, 3 times a day to pictures and videos of his sister. He never knew lingerie like that existed before, the lace and straps, the thongs and bikinis. He woke up in the morning, jerked off, did so once again as soon as he got home and once more before bed. It got to the point that even his girlfriend asked if everything was OK, seeing that his mind was occupied elsewhere. The couple of dates they went on, even the sex with her at the end of the night, Kevin spent thinking about Kelly.
