This is a work of fiction. None of this ever happened. All participants in sex acts are at least 18.
Stoney stood in the family bathroom, facing the sink, with his pajama bottoms pooled around his ankles. He watched himself in the mirror above the sink, admiring the way the daily PT and constant physical activity of life in the Army had sculpted his body. He had always been a little skinny, and the sports he played in high school never managed to put any noticeable muscles on his frame. He liked the look of his body, now. His arms sported triceps, biceps and forearms built up with rope climbing, pushups, and dips. The rest of his body was built for endurance, with hard muscles hidden beneath the thinnest layer of fatty tissue that could be called upon for reserves of energy on a long field exercise.
His eyes fell to his crotch, where his erection stood tall and proud. He had waited until the rest of the family was asleep for this bit of self-indulgent admiration, because he was intent on relieving his pent up sexual frustrations. His girlfriend had broken up with him when he joined the army, and now, nearly a year later, he was home on leave for the first time, only to find that his friends and acquaintances had all paired up in his absence, and nobody was available to date in the small town.
Stoney poured a bit of baby oil in his palm and rubbed it on his erection, taking his time. He squeezed his cockhead between his thumb and forefinger, then wrapped his hand firmly around his shaft and began to jerk it, slowly, while his other hand cupped his balls. He alternated between watching himself directly and in the mirror, loving the third-person view provided by his reflection. A drop of precum leaked from his pee slit, and he spread it around, mixing it with the baby oil.

Nicole knelt outside the family bathroom, listening carefully to the noises coming from inside. She knew if she waited for the right moment, she would be able to open the door just a crack and peer through without the person inside seeing her. They would be too distracted to notice.
Nicole had become quite good at spying on people in the throes of passion. For more than two years, she had been sneaking down the halls at night to watch her parents have sex. She would wait outside the door, listening, and once she knew they were thoroughly into it, she would open their door a crack and watch, rubbing her drooling pussy, circling her clit, and ultimately plunging her fingers into herself so she could climax at the same time as her parents, Ann and George. Nicole's friends claimed their own parents were staid and boring, rarely having sex at all, and it was both quiet and over quickly. Ann and George put on quite the show, however, and Nicole had gotten a pretty thorough education in what kinky things two people could do. Although she was still technically a virgin, she was definitely sex-obsessed.
She had been on the way to her parent's room, when she heard quiet sounds of male arousal coming from the bathroom. Intrigued, she had stopped to listen, wondering if her father was in there alone. Her parents had long ago had "the talk" with her, and explained that masturbation was normal, admitting that they both did it. Nicole had never managed to catch either of them at it, and thought perhaps this was her chance.
Nicole felt the familiar pounding in her chest that always accompanied her spying. Carefully, she twisted the doorknob slowly, and pushed at the door until just a crack of light appeared around the jamb. Her other hand pushed up inside the long t-shirt that was the only clothing she wore on her nocturnal expeditions, eschewing panties or socks. She cupped her left breast, and ran her fingers across her responsive nipple, which hardened quickly, begging for more attention. She gently squeezed it between her thumb and forefinger, biting her lower lip and breathing heavily. She pushed the door open a tiny bit more, peering inside.
Nicole froze, gasping. Instead of her father's squat form, she saw the tall, slim form of her big brother Stoney. He was facing the sink, giving her a side profile view of him, just 18 inches away from where she knelt peering through the door.
Nicole and Stoney were separated by just 18 months in age, and she had always looked up to her big brother. He was smart, caring, and helpful, and they had shared each other's joys and triumphs through the years. Although many of her friends disagreed, she found him handsome, and had harbored a secret desire for him for years. She had been disappointed when he joined the Army and moved away. She had always been a watcher, not a participator, and she missed being able to just stand in his shadow unnoticed. She had to admit that with him gone, she had become less shy and more assertive, since she couldn't rely on him to handle all the interactions with the world.
As Stoney stroked his hard-on, Nicole abandoned her breast, Frantically diddling her clit, attempting to catch up with him, as it was obvious he was getting ready to shoot. His cockhead was bright red, almost purple, and his butt cheeks were clenching, as he rose onto his toes. As Stoney grunted and exploded a jet of semen that painted the front of the cabinet with white fluid, Nicole plunged three fingers into herself, heedless of the pain of such a big insertion without proper stretching first. Her body tensed, and her pussy pulsed around her fingers as she experienced the most intense orgasm of her young life. She let go of the doorknob involuntarily, bringing a second hand to her crotch. Overbalanced, she fell forward, forcing the door open, and landing at Stoney's feet,

Stoney was thoroughly enjoying his wank, watching in the mirror as his cock swelled in reaction to his practiced technique. If he had been looking straight down at himself, instead of in the mirror, he never would have noticed the doorknob move, and the door slowly open just a crack.
The thought of being watched excited him and spurred him on, and he began to wank faster. He wondered who it could be. He could make out dark hair, parted in the middle, which ruled out his youngest sister Gwen, a redhead, and also his father, who was balding. So it had to be his Mother Ann or his sister Nicole.
The naughty thought that either of them was watching him was too much to bear, and his body clenched up. The hand cupping his balls squeezed down hard, and his hips thrust forward into his stroking hand. He felt a massive shot of cum work swiftly up the length of his cock. It impacted the door of the cabinet under the sink with an audible splat, and a second shot soon followed, falling a bit farther before hitting the door and sliding down. A third and fourth pulse dribbled down the fingers of his hand.
Suddenly, the door burst open, pushing him sideways as Nicole fell through the door and onto the space he had just occupied. His feet tangled up in his pajama bottoms, and he tumbled backwards into the tub, his head striking the tiled surround with a loud bang.
Nicole and Stoney locked eyes, Each in a mixture of surprise and embarrassment. Nicole lay on the floor, looking up, and Stoney lay with his knees on the edge of the tub, feet hanging out, and head propped by the tub surround. They were frozen for what seemed an eternity, but must have been only a moment. From down the hall, their father shouted "What's going on? What was that?".
Nicole scrambled back out into the hall, Stood, and raced off to her own room, not a moment too soon, because George came dashing down the hall, Ann on his heels. Stoney scrambled, trying to stand up from his awkward position. "Uh... nothing... I, uh... I was just finishing up on the john when I slipped and fell, " he stammered. "I hit my head, but I am ok. Sorry to wake everyone." Embarrassed, he pulled his pants up.
George and Ann took in the scene, the semen sliding down the cabinet toward the floor, the baby oil open on the countertop, Stoney's frantic movements to pull up his pajama bottoms. They exchanged a knowing look, and Ann said " OK, honey, be more careful in the future. Let me know if that bump on the head needs attention." They turned and left the bathroom, returning to their room, where Stoney imagined they would have a good laugh at what they THOUGHT was his predicament. He was relieved that they didn't know the full story.
Stoney cleaned up his mess and headed back to the bedroom he shared with his youngest brother, Ben. As he passed the girls' room, he saw them standing in the doorway. Gwen looked mystified, but Nicole exchanged a long, significant look with him as he walked past.
