Chapter 1: It was a bad idea

It was a bad idea. Susan knew it was a bad idea, especially after last time when Dan woke up just as she ran from his room. She just couldn’t fight it.

The urge started a few months ago when Susan had to turn around and go back home. She had left a book in her room. As she quietly walked down the hall she caught her little brother Dan walking from the shower to his room. He was wet and naked. Naked except for the small threadbare towel wrapped around his scrawny waist. It had been his favorite towel since he was little and should have been replaced years ago. It couldn’t get him dry and did nothing to hide his monster cock from Susan’s shocked eyes. While Susan had run away, Dan had failed to even notice his older sibling standing there. He was too busy scrolling his FYP.

The bulbous crotch creature stayed in her mind all day, and night. Susan woke up dripping wet her quim gushing from a dream of that cock sliding between her pussy lips and into her tight hot fuck box. After only 2 nights she could barely look her baby brother in the eye as she longed to feel it or see it again. Two nights more and she couldn’t resist the need to creep into his room in the dead of night. Opening the door that night was the most terrifying moment of her young life. Moonlight filled the room slightly, but enough. Pulling back the covers she gasped, quickly putting her hands over her mouth in fear Dan would wake up. Susan didn’t know that her brother slept naked, but she was pleased. His scrawny body made his dick look huge even before she ever saw it hard. Susan stood in silence staring at the soft 7 inch cock of her little brother. The very sight of it made her pussy drip. That night Susan noticed her favorite pj’s caused too much noise as she reached into her panties and touched her excited clit. The next night she stripped down to her panties and a crop top which barely covered her firm young breasts.

After looking at it while she rubbed her clit every night for a week, Susan needed more. Just staring at his soft cock wasn’t enough. Susan knelt down next to his bed. It took a few tries before she actually touched his naked flesh. Careful not to wake Dan up, Susan caressed his balls before running her fingers down his shaft. The beast awoke, stretching and swelling. Eager to show off its full and mighty form. Susan began to gently stroke her fingers up and down his shaft. The uncut head would hide inside its protective hood and would grow angry, turning bright red then deep purple. It would begin to bubble and ooze clear juice which Susan would use to lube her fingers and she rubbed herself to a leg shaking orgasm. Susan spent the next few nights stroking him while he oozed rivers of fuck slop as she made her cum hard. But Dan never came. He would wake up every morning hard, horny and aching. He started jerking off morning noon and night, right before bed.

Then about three weeks after Susan saw him naked, Dan got distracted at school and didn’t have time to jerk off at lunch. Then later when Coach had everyone run extra laps he fell asleep before he could get off. When Susan came in that night, he was already rock hard, juicy and throbbing with need. Susan wasn’t sure why he was already hard, but made sure he was still asleep before starting. She had barely touched his cock. Only stroking his shaft a few times. She didn’t even have her hand in her panties when Dan’s cock exploded, covering her face, shirt, and hands with thick heavy boy batter. The taste was amazing. She had to taste more.

Looking up, Susan saw her favorite toy was still hard, bobbing in the air. It moved in time with Dan’s heartbeat. At first she only used her fingers to scoop up any remaining cum but that was all gone in a moment. Without thinking Susan licked her lips and took her brother into her mouth. His cock tasted so good she couldn’t stop. She licked each and every vein and knob on his hard cock, before fucking her mouth onto his cock. Susan had enjoyed blowing the 3 guys she had dated, but Dan was better. That night Susan sucked her little brother off five times while she knelt naked next to his bed and rubbed his cum all over her even her wet pussy. She came over a dozen times.

Dan slept better than ever before. For the next few weeks, Susan spent hours blowing her brother’s cock while she rubbed her pussy. During the day she couldn’t stop thinking about using his cock to rub herself. Dan stopped jerking off but didn’t notice as he was calm and relaxed. Still Susan wanted more. One day Susan had woken up, her cunt on fire. Dripping with need. All day Susan found herself rubbing her clit through her clothes. That night she wore only a thin jersey of an ex, which she had cut so that it barely covered her tits. Walking into her brother’s room she felt on edge. Once Dan was hard Susan put one leg on his bed so that her dripping wet pussy was right over his cock. She rubbed his thick nobby cock with the lips of her hungry pussy. Not allowing him to enter her, but instead to slide over her. His hood would catch the tip of her clit and with each slide pull it back exposing more and more of his burning hot head. Once Dan’s entire crown was exposed his nerves took the full brunt of Susan’s cunt rub. Like most nights, his first orgasm didn’t take more than half an hour of play. Susan was so excited she didn’t notice when his swollen head engorged before exploding rope after rope of thick cum across her pussy, up her belly and over the underside of her tits. Susan’t orgasm quickly followed. Her legs buckled slightly as she continued to slide her pussy across her brother’s slick cock. Suddenly Susan froze. She had moved a way that allowed the tip of Dan’s cock to enter her pussy hole. A naughty thrill filled her body. Pushing slightly she allowed the top of him to stretch her open for a moment before reversing course. More and more often she moved so that the top half of Dan’s thick crown popped inside Susan’s pussy.

For the last two weeks Susan has cum over and over from the feeling of Dan’s swollen cock rubbing and moving thur her pussy lips. Each night his crown would pop inside her part way. She was letting more and more until last night his entire plum popped thru her tight slit. Susan came so hard.

Tonight, Susan knew it was a bad idea but she needed more of his cock. Naked on her brother’s bed Susan was on her knees facing away from Dan, rubbing her ass and cunt up and down his wet shaft, teasing his fat crown with her pussy. Getting him coated in her fuck slop.

Unknown to Susan, Dan had napped earlier and so he woke up as his cock was getting pleasured. Seeing only the smooth tight bubble ass in front of him Dan thought he was dreaming. Her hot pussy was burning his hard aching cock. As she moved up along his shaft Dan moved his hips changing the angle. Suddenly his crown popped into the wet gushy hole as she sat back. Not expecting that, her hole gobbled up his entire cock. Susan instantly came hard upon her lil brother’s cock and started riding his rock hard cock. Dan had never known such pleasure and fought to hold back. But he didn’t know that the weeks and months of nightly pleasure and teasing had increased his stamina. Dan groaned as this hot girl fucked him for an hour. Susan had one orgasm after another. Finally Dan’s poor balls couldn’t hold back and he exploded deep inside Susan’s squeezing pussy. Susan didn’t feel her lil brother loading her up and continued to ride him. Dan wasn’t about to complain, it felt too good and this was just a dream. After giving his sister his fourth creampie Dan passed out, but the pressure of Susan’s packed cunt kept his cock from going limp as Susan came once more. This final orgasm was so intense Susan squirted for the first time. Her whole body shook as Dan’s legs and sheets were soaked with her fluid. Susan couldn’t focus. This was the most intense cum ever. Susan leaned back, half on half off her little brother’s frail frame.
