Changing the Rules

As you sit on the couch, slowly stroking your semi-hard dick, your mind wanders through the past couple of days. You'd had some amazingly fun times so far but something nags in the back of your mind.

You remember something about being able to change anything you wanted. If only you could remember what the hell that horse's name was. You try to remember, thinking back, and then finally it springs into memory.

"Able Master!"
As soon as you say his name, a loud bang explodes behind you. You spin around on the couch, only to see a large white horse standing in your living room.
"What the fuck?!"
The horse looks down at you.
"What do you mean, 'what the fuck', you called me, dumbass!"
Once over the initial shock, you stand up and regain your composure.
"Right, so, if I remember correctly, you stand I can change anything I wanted."
Able Master sighs, or at least as much as a horse can sigh.
"Yeah, you can."
You cross your arms and stare down the intimidating creature.
"And how do I do that? Do I need to call you all the time and tell you what to change or what?"
Able Master laughs.
"Oh no, no, that won't be necessary. You can change anything by simply thinking about changing it. You'll need to concentrate pretty hard on it though. It's part of a safeguard we had to put in, one of the guys before you didn't have it and everything completely shifted at every little thought that popped into his head. It was a giant pain in the ass for all of us."

Ok, so just concentrate, doesn't sound so hard. You decide to give it a try. You close your eyes and picture that creepy-ass horse out of your god damn living room. There's a shuffle of hooves and then silence. You open your eyes and Able Master is gone.
"Hmm, that was easy."
You think about what you'd like to change. Not much comes to mind right away. The world so far has been tailored to the best time in your short, sad life. All the women are in their prime forms from your masturbatory fantasies. They all are willing, although somewhat **** but you like that sort of thing, in giving you insane deepthroat blowjobs all the time. Then you grab your dick and get an idea. You are only about 7 inches. That's about to change. You concentrate, closing your eyes, and picturing yourself with a 10 inch dick. You can feel it growing in your hand, open your eyes, and a huge grin comes across your face.

"This just got a whole lot better."
You try to come up with something else to change. That's when you realize you are standing alone in your living room. Having all these sluts to throatfuck is fun, but you'd kinda like someone to share it with. A buddy to help you hold a bitch down, have a spit-roast or some DP action. And that's when you remember an old high school buddy, Tommy. He always had your back even if he was a pathetic wimp. And since this is all in your head, you can control everything he does.
"Let's try this."
You concentrate on Tommy as you remember him. A scrawny 19 year old kid. You remember his voice, his mannerisms, his style, all the times the two of you hung out and joked about fucking every girl in the neighbor (if you could).

"Hey, David!"
You open your eyes and there's Tommy, standing in your kitchen, butt-naked.
"Whoops, forgot your clothes. Ah, well, with what I have in mind, you probably won't need 'em."
Tommy looks down as his nakedness and completely freaks out.
"Dude, What the fuck! I look like a fucking Ken doll!"
Tommy is not exactly anatomically correct, at the moment.
"Shit, my bad, I didn't exactly what to think about what your dick looked like."
Tommy is still freaking out.
"Well, fucking fix it!"
You close your eyes and try the same image you used to pump your own dick to 10 inches. Only this time, on Tommy's body. It's a little weird, you basically just give him your dick but only 8 inches. No reason not to have the biggest dick on the block.
"Oh, fuck yeah, thanks dude, it's bigger than before!"
You laugh at your friend.
"Don't mention it."

"This is your lucky day, my friend. This is heaven."
Tommy makes a questioning face.
"So, I ... died?"
You put up a hand.
"No, no, I died. Or so they told me. Technically, you aren't even here. You are just a construct of my memories. But, close enough. Anyway, the reason I brought you here is to share in the fun."
Tommy looks around your house.
"What kinda fun? Looks like the house is empty."
You grin.
"Oh, Mel and Rachel are around somewhere. But the fun ... the fun is that we are the only two men in this entire world. And not only that, but all the women are here to give us all the blowjobs and sex we want."
Tommy's jaw drops.
"You're shittin' me."
You clap him on the shoulder.
"I shit you not, man. I've been having the time of my life ... or **** ... the past two days. But I wanted to step things up a notch. By myself, I can only do so much. With you here, we have a few more options."

There's a noise down the hallway. One of your sisters must be stirring in her room. Tommy rubs his jaw, staring hungrily towards the noise and your sisters. You can tell he's thinking about fucking them. He turns and looks you in the eye.
"When do we start?"

You step past him and start down the hallway. Tommy follows behind you.
"Right now."
