Not-so-bad-bro's Still a Jerk

"Okay, I guess there's something going on between me and you," Derek says, the big lizard looming over you. You don't care what he did or said, the guy's a big menace, always was, always is and always will be. You feel yourself beginning to sweat more profusely, you could put up some big talk now, but you know you can't back it up, not against a guy of Derek's stature.

"Uh, lil' bro, you gonna take my hand or what?" the bigger lizard asks, a concerned look on his face. It's only then you realize the only reason he's on top of you is to help you get to your feet. After all, you're so used to him intimidating you with his mere presence, never did you once think that he'd try to help you. You hesitantly take his paw and the big guy rather easily pulls you up to your feet - damn, those muscles of his aren't just for show.

"Uh, thanks," you mutter.

"Don't mention it," your brother chuckles, the big guy sitting himself on his bed. You don't like the way he 'appreciates' your body. Especially that big foot long boner poking out of your shorts. Dammit, why can't you get this thing to go down?! Derek's practically screwing you with his eyes, a hint of mischief, or perhaps... lust.

"Derek, you're creepin' me out," you stutter, backing your way to the door.

"C'mon, Sim. You admitted it already, you like what you see... I like what I see," he rumbles, a bit too sultrily, his lips curling just a bit too much.

"Dude, we're brothers!" you hiss. "Oh man, Derek, you really are fucked up, you know that?!"

"Yeah?" he grunts. You can tell he didn't like the tone of your voice. You can see it in the way he gets up off the bed and saunters his way over to you, a billowing storm cloud of green and scales. He's barely half a foot in front of you, his thick chest in your face, your back to the wall. Derek plants a meaty hand between your head and the doorframe, a big smirk on his face as he looms over you; as if to say, "Where you goin', bro?"

Your brother brings his free hand up and pushes at your chin, forcing you to crane your head up. You try to turn, but he forces your gaze right back. "Fine. I guess I'm messed up. But..." He lets go of your head and you follow his gaze all the way down to your crotch, your member still throbbing achingly. Your face goes flush with embarrassment. "I'm not the one who's boning up over his big bro."

"I'm not!" you blurt defiantly. "You just caught me at the wrong time! I was just flexing for myself and-"

You realize all too late that that might not have been the best confession to make, your big brother's grin only growing. "Damn, Sim, boning up over your own body." He bends down and licks your snout again, the intimacy incredibly uncomfortable for you. "I think that's kinda hot."

You rub your snout dry and try to avoid eye contact. Derek's enjoying this way too much.

"Heh, don't worry, little bro. I sometimes do that myself," he growls.

"C'mon, Derek, stop, you're really scaring me," you stutter.

"Fine, fine," he huffs, pulling away. However, the moment he's about to back off, he's back in your face. "On one condition, Sim. You think you don't want it? Prove it, get soft," he chuckles. Your eyes go wide, your blood draining from you face when you feel a strong hand wrap around your king-sized member. You jump almost a foot off the ground.

"Derek! Oh my God, not cool," you yelp, bringing your hands down in a vain attempt to cover your arousal.

"Go on, try," he grunts. Your big brother pushes his chest out, his big pecs filling up that red t-shirt to the brim. You close your eyes and try to think of unsexy thoughts. You open your eyes to see him bouncing those luscious pecs and you regrettably begin to salivate.

Derek brings his arms down, puts on a stink face and puts on quite the show, flexing out his entire body for you, grunting and snarling at himself... or more likely to you. You swear you can see the imprint of his scales through the fabric of his clothes, the poor shirt and jeans look painted on. But, of course, that's not enough for Derek. You can't help but look, you're captivated by the expanse of his large body and Derek decides to give you even more of it.

The big lizard peels off his shirt, going topless in front of you, a big smirk on his face when he begins to roam over his own body, a deep rumble emanating from his throat, almost like a cat's purr. He winks at you and flexes a bicep for you, the swell of his arm must be around 16'', big and beefy, perfect for football.

All the while, you can't do what Derek asked you to do... you feel yourself whimper as you not only didn't go soft, your actually starting to spill a bit of pre! You try to hide it as best you can, but it's no secret that your body is loving the show, a big squirt of pre flings out, leaving a translucent streamer on hot liquid on the hardwood floor. You curse at yourself... dammit, dammit, dammit. C'mon, unsexy thoughts, bingo night at the retirement home, feral walruses copulating, naked pictures of Margaret Thatcher... Nothing's working!

You open your eyes to see Derek... fully nude, his jeans and briefs around his ankles...

"Oh my God, Derek," you blurt as you turn away. However, the image is burned into your brain, you can't unsee what you just witnessed - your brother was jerking off in front of you! "Okay," you yelp, not looking at him, "Derek, this is officially too weird." You sightlessly try to find the doorknob, taking a few moments to find it before turning it and opening the door.

As you run out, Derek yells at you, "C'mon, we're brothers. We're supposed to be comfortable around each other. An' nothing says comfort like a good jerk." You can hear him chuckling to himself, his laughter slowing giving way to grunts and pleasured moans.

You run out into the hallway and into your room, slamming the door shut behind and locking the mechanism. Your heart is pounding like a hammer. You groan as you crumple to the floor, you regret ever going into Derek's room. Sure you've got the body you've always wanted, but you shudder at the thought of your own brother coming on to you. Talk about a loss of innocence.

You sigh and look down, a look of disdain crossing your face. Does this thing ever go down?! You try pushing it back into your shorts to no avail. You try to just not think of it... But it's impossible, all it takes is the faint noise of your brother next door. He's purposefully being loud, you know he is. You close your eyes and try to block out the sound. You instantly regret doing so, the image of Derek playing with his own big ten-incher in front of you, flexing his big muscles...

Why can't you get him out of your head? You don't even realize how shallow your breathing has become, that you have one hand idly rubbing up and down the massive length of your member. You hear a loud roar shake the house and you try your damnedest to ignore it...

You listen to the silence, glad that you have it. Then, you begin to pick something up, the soft clanking of steel. Derek must be working out in his room.

You wish you didn't have an imagination... Derek's right, you are getting aroused over him. You can't see him, but in your head you can imagine him push that bar up and down, the sweat pouring off the ripped landscape of muscle and scale. You begin to get yourself into a rhythm, picturing your brother all sweaty, pumped after a good workout and working his thick ten inch prick on the bench.

Just then, you hear a thud and another loud roar ring through the air. Derek must really be enjoying himself. You guess that Derek must have rolled off the bench and onto the floor, writhing in pleasure, all pumped, sweaty and horny... God, you're such a pervert, thinking of your own brother like this!

But then... you hear another thud, and then another... that wasn't Derek falling to the floor... it sounds more like footfalls... of a giant. and they're getting closer. You begin to put two and two together, your heart racing. Derek used the bench! You gulp as your pulse quickens. The door rattles, a giant's fist rapping at the wood.

"Sim! Lemme in," a deep resonant voice booms. Oh crap! You jump to your feet and back away from the door, your back pressed against the far wall. "Open up, bro!" he barks. You just shake your head. Oh no, this can't be happening. "Dude, I'm comin' in!"

Derek literally rips the door out of its frame and you gawk at the monster standing in the doorframe. He's huge! Even more so than before. He has to go through the doorframe sideways to get in, his shoulders way too wide to fit normally. "Someone changed my settings," he rumbles. You gulp and nod, looking him up and down. 150%... Derek looks like an absolute beast of a lizard, standing at a proud six and a half feet tall, a whole foot taller than you now. But that does nothing to describe how amazingly large he is. 150% of nice and plump 16'' arms becomes absolutely gargantuan 24'' arms. His chest is so large, he's practically twice as wide as you are. His core is as ripped as ever, even beginning to distend out with the sheer girth of his muscles. Those thighs look as large as tree trunks... Speaking of tree trunks, you could describe his shaft as one. You could facepalm yourself... 150% of an already large 10'' monster has turned into an unspeakably large 15'' leviathan.

This cannot be good.
