Beyond Two Siblings

Breaking the Rules

There it was, both of their groins lined up against each other. The only border there was, were their clothes. Lincoln prayed that Lynn didn't feel the slowly rising hardness down in his pants. Speaking of which, as soon as he felt more pressure in his underwear, the more self conscious and aware he was. Lincoln could feel Lynn's body so close and near to his. If she tilted his head a little closer, they could've kissed on the lips. Her scent was slowly driving him crazy even if it wasn't anything new. But Lincoln guessed that puberty could really make you wake up to some things.

"What the?..." Lynn mumbled before looking down her shorts when she felt something touch her. What she saw almost made her wanna scream, or moan-from guilt. Whichever, basically.

"You can pitch tents in lockers but never when we're camping?" She sarcastically joked, before glaring at him. Hoping the fierce look in her eyes would be enough to turn him off. She anticipated this, knowing he was at that age. But still.

Sadly, with Lincoln's body being primal and ready, the same thing could be practically said with his brain. He was almost fully clouded with lust. A part of him still thought rationally, only to be swept away by a horny trance. As he looked into his sisters angry eyes, the more aroused he got. His hard on slowly clawed away at his pants, wanting to escape the fabric barriers.

Their noses were touching each other, their warm breaths mingling as Lynn's mouth was unnoticeably agape while she unconsciously panted at the tension.

"No, stop! She's your sister!" He thought to himself, but since he was a growing boy in the midst of puberty, primal urges kicked in and Lincoln sadly couldn't control it.

Lincoln bent down slightly, and started kissing his sister's neck. Because of his movements, their crotches bumped against each other with Lynn gasping in shock and becoming as red as a tomato.

"L-Lincoln..." Lynn stuttered out, trying to fight what she felt.

He didn't reply, well he couldn't. Lincoln was too preoccupied in getting a taste of his sister. It was too hard to resist. As he continued to kiss his sister neck, the more she also started getting affected by it. As it shows from the way she talks as if she's begging for more and how the jock gyrates her hips against his body.

Lynn wanted this to stop, more than anything! She didn't wanna be caught with her younger brother doing...things with him in the locker at the middle school! Imagine what that could do to their reputations? Or how it could affect their family!? But the ever-growing primal lust to grind was clouding her mind and her body had no control of itself anymore, just following the lead that Lincoln had started.

She tried to open her mouth to say something, but the only thing that would come out would be a series of small moans. And she knew that it was make him more riled up and Lynn wanted the exact opposite right now.

The jock was never the strongest at controlling her emotions and thoughts, most usually diving in head first without thinking. But now, she wished she was different.

Suddenly, Lincoln jerked upwards. The sensation it sparked was indescribable. It was like a wave of pleasure passed on from brother to sister and that made both of them become a pool of raging teenage hormones. Lynn shivers from the feeling as Lincoln bites his lower lip to stifle his groan.

From there, the two of them went wild. Finally succumbing into their primal urges and passion. Lincoln let's go of his sisters neck, with Lynn feeling cold from the separation. She whimpered at the loss of warmth, even though the locker itself was already pretty hot. Lincoln, following his instincts, pressed their foreheads together as he looked straight into her ocean blue eyes.

Lynn looked at him desperately, wanting more of the nirvana he was causing. Beads of sweat ran down their bodies as they both panted from the intense movements. Lincoln seeing his sister's rare submissive look got him harder- Lynn wasn't the type of girl he'd find sexy, but damn, did she nail the part right now.

Feeling powerful, he looked into her eyes with gusto while licking his partly dry lips and shoved their hips together, all the while grabbing her wrists and pinning then against the locker's walls. Lynn's pants became hitched breaths as she trembled from the pleasure. Sure enough, she felt warm gooey liquid slide down her thighs. When she was red before, then she was a complete tomato now. The sporty girl was redder than her jersey could ever be.

They both weren't sure if it was just them or it was really happening, but they could've sworn that the locker just got warmer. Ooh, now it was getting steamy. Would've been great if they could just take off their clothes and enjoy the free sauna-

Lincoln looked down to feel wetness against his jeans. He saw the source of the liquid coming from Lynn's shorts. It didn't exactly flow quickly like how urine should, so he guessed it could've been something more. Similar to what he saw in Lori's bed when he was on laundry duty.

He was 12, sure, but with the Internet and the lack of parental blocks, what did you expect?

"What! Are you really sure she did that!?" A woman spoke with a slightly Spanish accent as two frantic pairs of feet were heard walking away, startling both kids inside the locker as they stopped doing what they did. Lynn with a concerned look on her face, attempted to look up through the slits of the locker, but with a sigh of relief, went back down to her brother.

"Whew. They're finally gone." Lynn said, finally relaxing as she looked at her brother with half-lidded eyes. The load of stress being lifted from her shoulders made her forget what happened prior to earlier. Finally noticing how he was unresponsive, her big sister instincts came in and she snapped his finger to snap him out of his trance.

"Lincoln?" She asked, finally breaking him from his cloud.

"Lynn..." He started and then looked at their parts still against each other. She looked at where he was looking too and blushed. Before Lynn could say anything, he continued. "I-I'm sorry..." He said looking down on his bulge, trying to think of the worst things to turn it down.

"Linc." After a while of pregnant silence, which both siblings would've appreciated if this was home, Lynn called out with determination seeping through her voice.

"You don't have to apologize for anything... I-I..." She suddenly went hesitant, as if the girl was about to confess something.

"Huh?" Lincoln asked, just wanting to hide away from the world due to his shame. This wasn't anything he looked forward to and would've rather suffered detention with Mr. Fish for Breath for a whole day, even if the sensations were near- maybe even ecstasy.

"You know what? Let's go somewhere private." Lynn said, kicking the door open and dragging a surprised Lincoln along with her.

"Yeah, you're right. After all, it was getting hot in there. Hehe..." He giggled as he tugged on his shirt, blushing profusely. By hot, he meant in ways more than one.

The hall was empty at this point. It was so quiet, you could hear a pin drop. There wasn't anywhere in sight, and if this were a show, tumbleweed would've rolled by now to emphasize it. A few steps from where they used to be was another locker at the end of the hall, a locker in the school everyone knew about.

Both of them never spoke a word, afraid that it would attract any body's attention. They only waited until they were inside the lockers chambers and into the best room in the whole school.

"Uh...so why are we here in the arcade room? Don't you have classes?" Lincoln asked curiously, the boner in his pants slightly subsiding and is now at half mast. Wow, he can't believe he just did that to his sister. Lust still partly clouded his mind, so the thought of the trick they did back there made his manhood go back at full-mast.

"Well yeah, but there's some benefits in being the hall monitor. You know?" She flexed, proudly showing off her badge to Lincoln. "Besides, a little skipping won't hurt anybody. Unless you tell, of course." Lynn said, knowing the middle school more than anybody as she explored the deepest corners of it in her first year.

"Hm. Guess you're right." He said. Lincoln was normally the rational one between the two and he always disagreed to join in Lynn's escapades, but today was different. Very, very different. After all, you don't get stuck in a locker with a girl very often, do you?
