Each morning as of late, Lisa Loud woke from tantalizing dreams that induced curious physical reactions in her body, reactions that left her feeling flushed, winded…and sexually aroused. These dreams would linger warm and fuzzy in her mind as she lay in bed, and sometimes they would be so exhilarating that she would delay getting up until the last possible second. Oftentimes, she would be slick with her own natural lubrication, and more than once, she slipped her hand between her legs to stroke her clitoris to orgasm. She only did that on mornings when the pressure in her loins was too great; if she didn't, she would be in a state of excitement for the entire day, unable to concentrate, the same dirty, perverse thoughts running through her mind until her brain ached and she felt like her lungs were going to explode.

The morning of September 15 was one of those.

She came slowly and languidly awake in a bar of bright late summer sunshine, stretching and yawning like a cat. She could not remember the particulars of the dream she had been having but her body glowed with desire and her nipples ached so badly that she half way thought they were going to cut through the blanket like twin blades. She slowly rubbed her thighs together and grazed her hand over her stiff nipples, sending power pangs into her core. Her breathing became shallow and ragged, and her heart slammed so hard against her ribs that her tiny, perfectly sculpted breast shook and jiggle. She dipped her hand between her legs and swirled her middle finger around her clit in a lazy circle. Tendrils of electricity snaked up her spine and her breath caught. She arched her back off the bed and began to rub faster. Her eyes rolled back into her head and she panted for air like an animal.

When her orgasm broke over her like a bomb blast, she let out a little moan and clenched her butt cheeks. Her pussy pulsed and spasmed and she felt a little gush of liquid.

That was her having to wash her sheets again,

Third time this week.

After her body uncoiled, she laid there for a long time catching her breath.

It had been like this for what seemed like years. Lisa, now fourteen, had been going through puberty, more or less, since she was ten. Her hormones had been haywire ever since, but her body had been left behind, still childish in its diameters. Over the past year or so, however, it had begun to catch up…and then surpass. At a time when many girls were just beginning to take on a feminine body shape, she had the hips, breasts, and but of a much older and more mature girl…an older and mature woman, rather. She was more developed than even some of her older sisters and was the envy of all the flat chested Loud girls, which thus far was all of them, except for Lana. Lana wasn't as developed as Lisa was, but she was the second closest thing in the house.

While the girls of both the house and the town in general looked at Lisa with envy, the boys all looked at her with lust and desire. She was borh academically intelligent and wise beyond her years in other, more worldly matters - in other words, you could say that she was both book smart and street smart. She saw the way boys and even grown men looked at her, and she loved the attention they gave her. She had been something of an ugly duckling since she was a baby, but over the last several years, she had grown into her features. She was still relatively short at 4'9 but she was a healthy 120 pounds. For some women, that might be a lot - perhaps even too much - but on her frame, it fit perfectly. At school, the boys were all nice to her, whereas in grades past they picked on her. She was even sure that she had caught a few of the male teachers checking her out. She did not think that she could get any man that she wanted, but she was certain that if she so chose, she would never know a lonely Friday night.

Thus far, though the temptation had been great, she had not known anything other than a lonely Friday night. That's to say, she had never had a boyfriend and had never given serious consideration toward the prospect of obtaining one. She did, on the other hand, endevor to advertise her sexual self through what one might call flirting. Or, to be more precise, teasing.

And there was no boy she enjoyed teasing more than her own older brother, Lincoln.

Lisa was all too aware of the way Lincoln lusted for her. He made it quite obvious by the stares he believed were furtive and by the way he would "accidentally" brush against her when they passed in the hall. Lisa noticed all of this and was not above teasing him a little by walking around in a towel or neglecting to put a bra on under her shirt. One time, she was standing at the bathroom sink in nothing but a tank top and a pair of panties, brushing her teeth. Lincoln came in and joined her, only he stood behind her instead of to the side, where the was room. He reached for the medicine cabinet, and his erection prodded her butt cheek. The whole time he brushed his teeth, he nudged her with his boner, slowly at first, then faster as he became more excited. Lisa's entire body flushed with heat and her mind filled with hazy passion. If he had moved her panties to the side and penetrated her, she would have let him. She would have let him fuck her right there and then taken him to bed with her. Alas, however, that did not happen.

The taboo aspect of their flirting - as it were - excited Lisa to no end. It was wrong and dangerous and the sort of thing one ought not do with one's brother. That made it all the more appealing to her. Since she was a little girl, Lisa had studied science religiously - it was her religion - and had known from a young age that human beings evolved with biological mechanisms to prevent incest, namely pheromones. It would not be far off to say that the "scent" of one's sibling is sexually off putting. Knowing that incest was so taboo that her beloved sceicne had taken evolutionary measures to discourage it excited Lisa. Was it objectively wrong to feel carnal desire for a close relative? She honestly couldn't say that it was. Oh, she understood why human beings had historically avoided it, but outside of inbreeding, why was it so verboten? "It's gross"? Once upon a time, homosexuality and interracial relationships were considered gross as well. Once upon a time, no one washed their hands and everyone's answer for illness was praying. Things change.

At twenty-one, Lincoln still lived at home while attending classes at Royal Woods Community College. He also had a part time job at a local pizzeria which often kept him away from home until eight or nine o clock at night, sometimes later. Sometimes Lisa waited up for him, as they would often talk before bed. Having someone to talk to, someone with whom you can connect is vitally important for one's mental and emotional wellbeing. She enjoyed her nightly chats with Lincoln, but then again, she enjoyed being close to him in general.

A few times, she waited up for him in his bed, dressed only in a T-shirt and a pair of panties. She made no serious effort to outright seduce him, but she made sure that she cut a seductive figure, and did her best to communicate with him through looks and body language that she was interested and available. She thought that he picked up on those signals, but he had never acted on them. Call Lisa old fashioned if you like, but she wanted him to make the first move; she wanted to feel wanted and desired, and initiating a sexual or romantic encounter doesn't achieve that effect. She wanted him to be so overwhelmed with lust for her that he took the bull by the horns and had his way with her. God, if he did that, she'd let him do whatever he wanted to her.

She was beginning to suspect, however, that Lincoln was not going to do that. Perhaps he felt some misguided sense of morality that prevented him from taking the final plunge, perhaps he believed he was misreading Lisa's signals. Whatever the reason, he was reluctant to make good on their mutual flirting. For that reason, Lisa decided, she would have to be the one to get things moving.

On that morning, after masturbating, she climbed out of bed and made her way to the bathroom. Since the majority of her older sisters had gone off to college and to start their own lives elsewhere, the ubiquitous long lines at the bathroom had become a thing of the past. At almost any time of the day and night, one could expect to be in and out in a breeze. Lola showered in the mornings and spent a good forty-five minutes in there, but otherwise, the bathroom always seemed to be open.

Lisa showered, brushed her teeth, and wrapped the towel around herself. She went into the hallway and, to her delight, Lincoln was waiting for his turn in the bathroom. His eyes instantly flicked to her bare legs and his cheeks flushed red. "Hey," he said nervously.

"Good morning," she said. She looked him up and down, allowing her eyes to linger on the bulge in his underwear. It occurred to her to reach out and grab it, to knead it with her hands until he was shaky and rolling his eyes, but she stayed her herself. "You're running late," she noted.

Usually, he was already gone by now.

"Class got canceled," he said, "someone, uh, phoned in a bomb threat."

Lisa rolled her eyes. "Let me guess. Poppa Wheelie?"

Poppa Wheelie was one of Lincoln's friends and had a reputation for going to extreme measures to get out of having to go to school. Lisa didn't understand why he was continuing to do that sort of now that he was in college, college being entirely elective. No one forces you to go to college. In fact, you have to pay for the privilege. Why would you sabotage yourself like that?

Then again, no one had ever accused Poppa Wheelie of being intelligent.

Lincoln laughed and rubbed the back of his neck."Maybe, I don't know. It's not like I was involved in it."

She knew that. Lincoln took his studies very seriously.

Lisa found his fastidiousness very sexy.

"Well…enjoy your day off," she said. She brushed past him and went into her bedroom, resisting the urge to look over her shoulder to see if he was watching her, Inside, she went to the mirror and brushed her messy brown hair. She considered straightening it but decided against it, as that process was long and pointless. It would only last an hour or two, and then her hair would begin to curl pulled it back into a sloppy ponytail and then dressed in a skirt and a button up blouse. She sat at her computer and allowed her thoughts to drift back to Lincoln. Her core twinged, and her nipples stiffened.

This was it, she decided.

This was the day she would seduce him.

She decided to skip school for the day and stay home; the middle of the day was the only time they could be guaranteed privacy. She waited until everyone else had left for the day, then went to Lincoln's room, where he was sitting up in bed on his laptop. "You're still here," he said, sounding both surprised and pleased.

"I'm working on an important experiment and decided to skip my classes for today. I was wondering if you might be able to assist me."

Lincoln closed his laptop, sat it aside, and swung his legs over the edge of the bed. "Sure," he said, "always happy to help."

A devilish grin spread across Lisa's face. "Come with me."

Heh, she thought to herself. Cum with me.

In her room, they stood next to the bed. "I'll need you to strip to your underwear," she said. "Then lie flat on your back." She nodded to the bed, indicating where she wanted him to lay. He furrowed his brow and favored her with an incredulous look. She responded with a broad, toothy smile. "Pretty please."

He sighed. "Well…because you said please." He awkwardly removed his shirt and unbuttoned his jeans. Lisa did her best not to oogle his body, but she found it difficult not to. Done, he laid on the bed, back straight and legs together. "Alright," he said. "I'm ready. What are we doing?"

Lisa said, "I want to test the sensitivity of your erogenous zones."

Lincoln blinked. "My what?"

"You'll see," she said.

Standing over him, she laid her hands on one of his legs and slowly caressed up to his thigh, her palm grazing his skin. Lincoln turned a light shade of red and sucked a deep breath. She skipped over his bulge and skimmed her hands lightly over his stomach. She reached into her pocket, pulled out a pen, and used it to make a gentle circle over each one of his nipples. He stared straight up at the ceiling, avoiding eye contact, His chest rapidly rose and fell and he visibly suppressed the urge to squirm. Lisa skimmed the pen down his chest when she got to the very bottom of his stomach, right above his crotch. He gave a spasmodic, body-wide jerk like a dead frog when you shock it with electricity, and Lisa smiled to herself.

Done with the pen, she switched to using a feather, touching and tickling each of his body's most sensitive areas. She purposely avoided his growing bulge, letting him soak in anticipation as she kneaded and massaged every other point of his body. His face was beet red now and his lips were slightly parted as he took tiny sips of air. His erection strained against the cottony confines of his briefs, jerking and twitching like a mad dog on a short leash. Lisa licked her lips as she stared down at it, her core bubbling with passion. She finally decided to move onto the main course, but she still wanted to take her time with it.

She swung her leg over Lincoln's stomach and shifted herself onto him. She straddled him, facing away, her butt pressing against his abdomen and her knees caging his hips. Her butt and body blocked his view of what she was doing; he had no idea what was coming next. Bending forward, she splayed her hands on the insides of his thighs and placed a light kiss on the tip of his erection, her moist lips wetting the fabric of his underwear. Lincoln's breath caught and his body clenched beneath her. She tilted her head to the side and kissed it again, moving her lips over the head and along the shaft. She could feel his heat soaking through the material. Lincoln's breathing grew ragged and unsteady, and he gently thrust his hips back and forth, trying desperately to sink his sheathed cock into her mouth but missing each time.

With her thumb and forefinger, she peeled his underwear down and freed his cock; it sprang out in a swish of musky air, and its baking heat enveloped her. She let out a shivery breath that blew across it and made it twitch. An idea came to her, and she took out the feather again. She used it to lightly tickle Lincoln's raging boner. The skin contracted and the vein at the base of his shaft throbbed wildly. She swirled the feather around his tip, and his cock jerked and jigged back and forth like a plam tree in nasty winds. Lisa watched, transfixed. It was both amusing and extremely arousing. She had the urge to lift her skirt and sit on it, but she remained where she was. Lincoln dug his fingers into her thighs and gasped for breath under her assault, his dick pulsing like a rapidly beating heart. She ghosted the feather up and down his dick, sensing the immediacy of his impending climax. He lifted and lowered his hips with mindless abandon, any timidiy he may have felt gone in the face of the ultimate pleasure she was meteing out to him. She leaned in closer so that her moist breath broke across his dick and focused on that knotty vein at the base of his manhood, enamored of the way it pulsed. Lincoln lifted his butt off the bed and held onto her legs, his nails digging into her flesh. She moved the feather up and down, up and down, grazing his shaft. His dick was bright red now, glowing with heat, and his body trembled.

At the last minute, she removed the feather, leaned in as close as she could, and blew a puff of air against him.

That was it.

His dick erupted in a geyser of silvery white seminal fluid. It spurted into the air in fat drops and landed on the bed between his legs. Lisa watched in open mouthed amazement as he came. The second volley landed on his balls and matted his pubic hair. The third went splat on the inside of his thigh. His moans and twitching tapered off, then he was still.

"Thank you," she said breathlessly, "you've been a…big help."

From that point on, Lincoln gladly helped Lisa with her experiments, and always looked forward to finding out what she had in store next.

THE END
