The consequence
Lincoln's innocent, yet quizzical gaze refused to leave her increasingly blushing face after she blurted out her darkest secret.
"Wh…what do you mean…that I made you feel the same way?" He sniffled quietly.
A swell of anger, anxiety and other emotions she did not like or understand swirled around in her gut.
"What do you think I mean?!" she yelled.
The jock instantly regretted her outburst when her little brother cringe in fear. He tried to back away but Lynn's grip around his waist held him in place.
"Look at me" she said in an usually calming tone.
Even though he still quivered, he managed to look into her serious gaze with his tearful eyes.
"What the hell do you expect Lincoln?" she asked with an angry expression.
"I…I don't understand" he whimpered.
Suddenly, Lynn shoved her little brother against the wall before sitting up and crossing her arms in a huff.
"Are you that dumb?!" she scowled.
Seeing that he was genuinely confused and upset, she made herself take a deep breath before grabbing his hands with her own.
"…you don't know how perfect you are, do you?" she whispered.
The boy tried to respond but she pressed her index finger against his perfect lips.
"That didn't need an answer Stincoln. If…If you tell anyone what I'm about to say, I will end you!"
His nervous stare was all that he could offer.
"Here it is…"she muttered before he could begin to think of a response. "When you parade around in your underwear, you…you make me feel things I shouldn't feel!"
Lincoln could not even process what Lynn had just divulged before she grabbed his shoulders and pinned him to his bed.
"Do you do it on purpose…?!" she hissed.
"L-Lynn…"
The terrified boy didn't even have time to think of a reply before Lynn slammed her lips against his. His shock would have been apparent if her eyes were open but she had waited for years for this to happen. His first instinct was to push her away but when she slid her tongue against his lips in a desperate attempt to gain access, something within screamed at him to open his mouth. The moment he decided to give in to the desire, Lynn cupped her hands against his flush cheeks and probed his mouth with excessive voracity.
"D-Damn, Linc…" she uttered after having to release their lip lock in order to breathe. "You taste as nearly as good as you look!" she winked.
"…What's happening…?" he asked timidly between rapid breaths.
Even though Lynn felt a swell in his underwear when their tongues finally collided, she noticed that his eyes were filled with uncertainty, confusion and fear. Annoyingly, her conscience stopped her from ripping his clothes off and having her wicked way with him. Sighing deeply, Lynn clambered off of her victim and sat on the edge of his bed with her head in her hands while he continue to lay there and stare at the ceiling in shock and confusion.
"I'm sorry Lincoln…"
He was in too much of a daze to respond.
"I…I just got over excited"
Lynn eventually crawled over to him on her knees and placed a hand on his chest, quietly cursing the orange polo that hid his perfect skin.
"We can't do this…" he whispered.
"Well…why not? We both clearly want this"
It was Lincoln's turn to feel a pang of anger. "Because I'm your brother and you're my sister!"
The sporty girl looked down at him with a similar look she gave him when he initially refused to let her bunk in his room, a memory that she cherished. Without asking, she leant down, wrapped her arms around his torso and placed her face near his armpit. She did not even try to hide the fact that she began sniffing his underarm.
"Lynn…" the boy whined before trying to move away but she refused to let go.
"What? You sniffed my crusty socks" she grinned slyly.
"Only because you made me!" he yelled.
"True…but I didn't know that I'd make you blow your load" she snickered.
His cheeks became bright red and he turned to face the wall in embarrassment and disgust at himself.
"I…I didn't mean to do that…"
"I know…" she replied with a rare sympathetic tone. "Fair's fair though"
"Huh?"
"You got to enjoy yourself, so…"
The white haired boy sighed in exasperation knowing that he was not going to be able to get out of this.
"You don't have to do anything, just lay there…Stincoln" she growled seductively as she grinded her crotch against his thigh.
The young boy gulped in slight fear and anticipation before giving a slight nod with his eyes shut tight. Seeing this as a green light, his big sister wasted no time in burying her face in his unwashed pit and greedily inhaling his sweaty boy smell. His scent made her moan and quiver in ecstasy so she could not help shoving her hand down her shorts and begin pleasuring herself.
"You…You smell so awesome Linc…!" she huffed. "You should be banned from showering!"
Lynn's words and actions made his face almost beet red. In his wildest dreams he never imagined that an attempt at tutoring one of his sisters would result in her sniffing and humping him. Her fingers quickly became slick with her juices as she quickened the pace and her moans became louder.
"Not so loud Lynn!" he whispered, his eyes were still closed tight.
An idea quickly came to mind and without warning, she removed her arm from underneath him and proceeded to lift his sweaty shirt over his head before clamping her mouth onto his exposed, hairless pit. This managed to muffle her pleasure filled whimpers significantly but now Lincoln was the one that had to try and keep his yelps quiet. The feeling of her tongue sliding and swirling around his armpit made him bite down on his knuckle because of the strange combination of ticklishness and pleasure that he felt. His cock was painfully hard inside his underwear even though he had just experienced probably the most explosive orgasm of his life minutes ago. He desperately wanted to relieve himself but he thought that this situation was depraved enough so he continued to lay there until Lynn finished and judging by the increasing rapidness of the primitive noises escaping her, she was close. It got to the point that he could hear the squelching of her juices mingling between her fingers and bald pussy.
"Li…Lincolnnn…!" she growled between her teeth. The feeling of the impending eruption excited and scared her.
Seconds after saying her little brother's name, Lynn removed her hand from her shorts. grabbed the side of his head as she violently humped and grinded against his underwear. The orgasm that followed shocked her whole body. The jock trembled uncontrollably when she felt her girl cum gush through her knickers and soak into her shorts. Lincoln nearly came again just by hearing and feeling his sister's performance.
"W-Wow…th-that was better than any workout!" she chuckled breathlessly, not caring that she was soaked with sweat and other juices.
"I'm glad you enjoyed yourself" Lincoln replied trying to sound annoyed as he pulled his shirt back down and used his bedsheet to rub her cum off of his cheek and temple.
"Now we're even" she winked, giving him a light punch on his arm. "And now to celebrate a great workout with a meatball sub!"
Once she threw the covers to the end of his bed and stood back on her feet she looked down at her sweaty little brother in admiration. She was about to leave until she noticed a huge tent in his tight underwear.
"Woah…want me to take care of that before I go?"
"N-No!" he whimpered before quickly hiding his shame with his hands. "We've done far too much already, we've crossed a serious line here Lynn…don't you get that?!"
"Ohh..I-I guess…" she replied in a faux defeated tone. "Just one thing before I go"
The white haired boy sat up on his elbows and looked at her quizzically
"What is it?"
Her gaze never left his as she lifted her legs and peeled of her stinky socks one at a time before throwing them at Lincoln, one fell across his stomach, the other landed in his snowy hair and drooped down to his nose. He tried to look angry but just lightly inhaling the smell almost made him cum immediately. Lynn gave her signature laugh and blew him a kiss before leaving his room and closing the door behind her.
"Dang it…" Lincoln knew that she knew he would not be able to control his urges so instead of fighting it, he gave in, pressed her sweaty socks against his adorable button nose and had the quickest wank of his young life. In less than a minute he shot a load of watery cum up his heaving stomach and chest. Eventually he came back to earth and now he no longer had a loaded gun, the feelings of pure anxiety filled the magazine.
"What the heck have we got ourselves into…?
