Overlooking the City

One-Shot Challenge #1

Racercest

Speed had been driving the Mach 5 down the road toward his "spot", the one where he went when he had depressing thoughts and romantic, but so confusing feelings. As these two things were now currently occupying his mind, Speed had fled his home and drove quickly away, but now, as he sped around a corner, almost running into a pedestrian car, the racing car driver decided that he needed to go somewhere different, away from the reminder of Trixie.

"Damn that stupid woman..." Speed cursed as he gunned the engine, the Mach 5 purring in response as it sped faster down the mountain highway. Trixie had ruined everything he might have had with Racer X and he couldn't believe how dumb the woman was until that very moment. How could she spout such mean gossip about Racer X right in his face? Couldn't she have seen that it was hurting him? Sighing loudly, the brunet turned quickly up a dirt road leading to the the top of the mountains he had managed to find. Pressing the F button on his wheel, the grip tires popped out, easily tearing through the dirt as he sped up the mountain road. Little did he know that the yellow and black car of Racer X was following behind him with a bemused driver at its wheel.

Spinning once before his anger finally dissipated, Speed sat, panting, as he tried to rein in his emotions. He couldn't believe how incredibly mad he had gotten at Trixie for something so trivial as her stupid gossip. He never got truly angry over anything!

"Why him? Why does he make me do things I normally wouldn't? And feel so weird...?" Speed mumbled to himself as he let the Mach 5 turn off with a touch of the key. Slipping from his car, this time by actually using the door, the brunet made his way to the railing, leaning heavily against it as he looked out over the bright city. Groaning at all of the confusion he felt, Speed closed his eyes tight, thus not seeing the silent Shooting Star pulling up behind the Mach 5. But he did feel the hands that caressed his sides as he shivered, opening his deep blue eyes as those wandering hands suddenly dived into his white leather pants.

"Ah! St-stop!" Speed protested, though he began to respond to the touches his assailant was giving him.

"Shh, Speed, just let everything go, relax... let the pleasure take you away from your worries..." Racer X's voice was a silky as usual and Speed almost immediately was lulled by it, rocking against the hand that now held him captive.

"Ah, Racer X, p-please!" the Grand Prix winner begged, blue eyes hazy with lust as he tried to turn toward X. Leaning into the smaller body, the older male quickly pinned his smaller companion against the railing, eliciting a long drawn-out moan from the brunet. Shifting slightly, Speed blushed deeply as he felt something thick pressing into his butt cheeks, letting out a gasp that made Racer X groan heavily in return.

"Will you let me...?" Racer X breathed out as he rubbed himself against the other shamelessly, moaning when the response was Speed pressing deftly back into him.

"B-be gentle please..." the younger male stated as he was stripped of his clothing, finally turned around to see Racer X just as naked as he. His brown eyes stared deeply into Speed's blue orbs, causing the uke to hold a breath as he chanced a glance down. Eyes widening at the size of Racer X's cock, Speed suddenly gasped when the taller male pressed him back against the railing, gently kissing the smaller "man".

"I'll be as gentle as possible. Trust me..." Pulling something from his leather pockets from his discarded clothing, Racer X flicked open some lube, dipping long fingers in it as the brunet beneath him moaned loudly. The sun behind Speed made the innocent racer seem as angelic as he was when he was young and the changed Rex Racer almost felt guilty at fucking his little brother. Almost.

Kissing Speed and pumping him with one hand, Racer X gently spread apart his brother's butt cheeks, stroking the tense hole for a moment before Speed relaxed enough for him to penetrate the uke's entrance.

"AAH!" Speed gasped at the strange sensation, eyes going wide as Racer X added another finger. His pain soon turned to unmounted pleasure as X hit that bundle of nerves deep inside Speed.

"Aaaah...p-please...!" the uke begged, lower lip trembling as the hand on his cock tightened and a third finger was added. The ecstasy was getting to the smaller brunet's head as the fingers left him, Rex's brown eyes softening as he watched his younger brother pant for a moment before he promptly switched Speed's position and as slow as he could shifted himself into the tight heat.

"Aaaah, it hurts!" Speed whined, tears falling from his darkened blue eyes. Racer X paused, his heart stopping itself as the image of a pained, and bleeding younger Speed filled his mind. Then Speed shifted, all of Rex's cock suddenly disappearing into Speed in one fluid motion. Said uke whimpered at the pain before he gasped loudly, X grinning at him in triumph.

"Speed... you like that?" Racer X breathed out, his breath sending a shiver down the Grand Prix winner's frame.

"Yes...yes!" Speed moaned as Rex began to pump his shaft again, getting a rhythm easily as the smaller male began to push backwards, allowing for deeper access.

"Open your eyes, Speed... look at what's displayed just for you while you writhe in pleasure..." The words caused the whimpering racer to open his blue eyes wide, gazing over the bright and flashing town he had grown up in. The dazzling lights and the flashes of pleasure had Speed reeling as he was fucked thoroughly, Racer X all but moaning his appreciation of the younger male's enthusiasm.

"AaaaaaAAAAH!" Speed screamed, pitch going up an octave as his orgasm overtook his control and his cock spasmed, white spurting from his tip as he clenched around Rex's cock. The intense tightness surrounding him made the older male groan out his own orgasm, thrusting harshly as Speed trembled from his mind-blowing orgasm. As the two began to come back down from their highs, Racer X began to pull out of Speed but stopped when the uke whimpered pathetically, hands gesturing wildly. He leaned back forward to hear what the Grand Prix winner was trying to say when he heard the sigh that left Speed. Smiling and shaking his head, Rex let his little brother enjoy the filled up feeling he knew he was currently feeling as long as he could. He smiled sadly then, letting himself press securely into the other, who shivered at the contact.

"Speed, we have to be going... We can't stay here like this forever, there's supposed to be a storm coming tonight..." Ecks whispered in his ear, making Speed smile contently as he began to feel the ache in his arms and legs from the strange position he was in. Not only did his limbs ache, but his entrance was filled with a yearning ache that had him gasping at the magnitude at what they had just done.

"Racer X... I-I love you..." Speed said with the biggest grin Rex had seen on his face for the longest time. Before the older male could respond, there was a thud behind them. Pulling away from Speed, Ecks leaned backwards enough to see the unconscious figure of Trixie on the ground in front of their oddly placed cars.

"What is it?" Speed asked curiously over his shoulder, letting Racer X pull out of him as he stood. Rex grinned back at him as he helped the shorter man to stand.

"It seems we had an audience..." When Speed finally spotted Trixie, his blue eyes widened to painful lengths and he coughed suddenly as all Racer X did was chuckle.

"Th-this isn't funny! She could expose us for-" a finger was over his lips, causing him to pause in his ranting.

"I don't think she fell over just because she found us out... or she would have said something earlier..." the shocked and slightly scandalized look on Speed's face had Ecks laughing fully as he pulled on his pants and jacket.

"W-what do you mean- she was here the whole time?! And you knew?!" Speed pointed accusingly at the older racer who shrugged.

"Doesn't matter..." he said as he stepped in front of Speed and gently kissed him. "I've got to go... it was nice seeing you and... I love you too..."Smiling at the shock that now overtook the brunet uke's face, Racer X moved to Trixie and carefully put her in the Mach 5, which seemingly purred at him. He glanced to Speed, who was gaping at him openly now. Sighing, Ecks stalked up to him and grabbed the dazed man, making out with him thoroughly and bringing the other out of his haze. Pulling back, Speed then grinned again, kissing Racer X again before the other could step back. When air became a necessity, the two smiled at each other before Ecks backed away.

"When will I see you again...?" was Speed soft question as he locked his blue irises with that of the brown ones. Mask in hand and his other hand gripping the driver's door of the Shooting Star, Racer X smiled sadly at the question before jumping into his car and turning it on.

"Someday soon... I promise..." was his reply before he sped off into the darkness. Speed gripped at the red socks in his hands before he quickly pulled on the rest of his clothes and jumped into his own car. Glancing to the woman he had thought both as a girlfriend and a bitch (though he was too nice to say that aloud), Speed sweat dropped as he realized that Racer X was right in the fact that she had been there watching them for awhile. She never drooled unless it was over something beautiful...sexy as she sometimes described it. Maybe she would support their relationship... if that was what this thing with Racer X was. As he pondered this, he turned on the Mach 5, its engine roaring proudly as he raced down the mountain road again.

"I can't believe you two had mansex... it was sooooo sexy..." came Trixie's dazed voice as she pulled her head from its position of lying on the door. Her eyes strayed to Speed, who sheepishly grinned.

"Ok..." was all he said before her eyes widened.

"You have to let me watch you guys go at it again or I'll tell Mom that you already lost your virginity! And not to mention to a man!" the gasp that Speed produced assured Trixie's victory as he tried to wrap his head around the events of that day.

"Ugh... I can't think anymore..." he murmured tiredly as he slammed down on the pedal, easily going 100 mph.

"Just get home and sleep... You'll be sore in the morning, after all..." Trixie replied as the Racer home came into view.

"Sleep...sounds good..." Speed mumbled as he pulled the Mach 5 into the garage, watching as his ... girlfriend? Naw, his best... slightly crazy friend climbed out of the car awkwardly. Gesturing to Speed, the racer jumped from the car to stumble and fall flat on his face when a pain shot through his spine.

"Owwww..." the brunet mumbled as Trixie kneeled down and picked him up to his feet.

"I would suspect so... that was so cool beans of you two!" she squealed as she lead him to his room, where he promptly fell on the bed with an exhausted yawn.

"I'll cover you for everything, ok?" she got an incoherent whisper to her question and she smiled as she walked out of the room again.

"Crap, I left my helicopter up there! Oh, well..." Trixie shrugged as Speed turned over in his sleep, thoughts swirling into dreams of a time where his brother was alive... of the one time that he had gotten to drive the Mach 4...

"...Rex..." was his last mumble before he fell asleep.

Woot, one down, four to go. This leads into a kinda flash-back shota mansex thing that happens.

Until next time!
