A visit to Shelly.

A quick turn to the left and you're facing Shelly's door. There are a couple of reasons why you've chosen your sister as your guinea pig for tonight's experiments. First, you've already interacted with her in the dreamscape and it hasn't had any ill effects on her--at least, not that you've noticed--and the shadowy monster you'd seen in Penny's dream hadn't been there either. Second, she deserves a little bit of **** for walking in on you earlier without knocking. And third...well, you can't deny she's hot as fuck. Maybe I'm just a big fucking pervert, you think.

Without hesitation, you push the door open and step forward. Just as you cross the threshold, movement catches your eye. An insubstantial shape, just at the point where the distance narrows the hallway down to a singular point. You might even be imagining it. The movement only has an instant to register and then you're through the doorway.

It's Shelly's bedroom. You look around, noticing minuscule differences: it's a bit cleaner than normal, the posters on her wall aren't hanging at crooked angles and her bedsheets look like they were put on her bed by a professional maid. Your sister isn't here. Interesting.

Okay. First, let's see if I can control the environment, you think. You have a list of things to test and this particular one seems easiest at the moment.

With focused thought, you picture how you want the room to change. You feel some small resistance and push harder. Then the room snaps like a bubble and your own room appears in it's place, almost like it was always there and you just needed to remove Shelly's room to see it. It looks exactly like you pictured it in your mind; in fact just like it looks in the real world, with your rumpled bed, old oak dresser and computer laid out in their proper locations. You grin, excited. Control of the environment, check!

The next test on your list deals with changing your physical nature. You have a floor length mirror hanging beside your closet, and you stand before it, looking keenly at your reflection. You're as naked as your were when you went to sleep. You concentrate again and as you watch, your mirror image slowly begins to grow taller, your legs and torso growing in equal amounts. A buzz shoots through you at the possibilities.

And then you do what every guy would do. You turn your gaze lower and laugh out loud as your cock lengthens and swells until it's sporting monster proportions: more than foot in length and about as thick around as a soda can. You grab it with both hands, amazed that you can truly feel the change in its weight, its solidness.

You don't know why you were graced with this power but at this point, you're not going to complain.

Satisfied with your new--if somewhat ludicrous--appearance, you sit down on your bed and start jerking your cock. It takes forever for your hand to ride your shaft from base to tip, but the sensations are fucking amazing down the whole length. With a thought, you let the dream continue forward.

In the next instant, your door flies open and Shelly steps in, again entering your room without knocking, just like earlier today. She opens her mouth but you hit pause before she speaks, freezing her like the still from a movie. She's wearing the same outfit from before, a t-shirt and jean shorts. It's a nice outfit, but we can do better, can't we? Let's see how my control is over the doorway's owner.

With another snap, her old clothes disappear and are immediately replaced by a classic little black dress, with short skirt and plunging neckline. Hmmm...a good choice, but let's explore further. The dress changes to a bikini, a replica of one you know she has in her closet. Her hefty chest is bursting from the tiny top and the briefs are cut so thin that you know she must at least wax her pussy. Sexy, but it doesn't really match the scene. But I'll keep it in mind for the future. The swimsuit is whisked away and Shelly is now standing in a baby blue lingerie set. The main piece has an opaque corset top which pushes her large tits high on her chest, with the only things holding back the mountains of succulent flesh being three small, delicate buttons. Hanging below this section is a diaphanous, see-thru material that showcases her toned, athletic body, sculpted from years of yoga. The lingerie also feature a matching pair of panties, easily seen through the translucent cloth. Your mouth waters. Pretty damn perfect.

But you're not done exploring your limits. You stare at her already large tits and watch as they plump up, straining at the corset top, pushing it out and placing an enormous strain on the buttons trying to hold everything in place. The upper slopes of her titties spill out from the top, increasing the chasm of her cleavage and sending shudders of lust through your huge member. Just before the buttons hit the point of no return, you stop, leaving Shelly with an unbelievable rack that's threatening to burst out at any second.

Ready, you unpause the scene.

"Oh, my fucking God!" she exclaims. Her eyes have locked on your meat pole and her mouth is hanging open in wonder. "Your dick is fucking huge! When did my brother become hung like a damn horse?"

You keep slowly stroking your cock and her chin rocks up and down, mimicking your own motions. As if drawn by a magnet, Shelly moves a step closer, and then another. Her giant melons dominate your vision and you groan at their closeness.

"Oh no," Shelly says, concern in her eyes. "Are you in pain?" You nod emphatically. "Is it blue balls, do you need to cum?"

"Desperately," you tell her. "I've been jerking off for the longest time but I just can't make myself cum!" She sits down on the bed and you're intoxicated by her hotness. You'd like nothing more than to throw her down on your bed and ravage her pussy like a beast hungry for meat, but you still have items on your list to test. You've set the scenario and placed the actors in their roles, similar to what occurred in the real world. Without prompting, Shelly's already moved in an incredibly different direction that her previous reaction. Where will she go from here? Will she keep pushing everything further down a sexualized road, or will she ratchet it down, closer toward her normal interactions with you, her brother?

"Don't you normally watch porn when you jerk off?" she asks innocently and you jerk your head toward her in surprise. Well, I guess I didn't need to wait long for that answer.

"Yeah," you say. "I guess that's true. I have some on my computer."

"Here, I'll turn some on for you. That should help you masturbate!" Her exuberance is puzzling. It's not something you changed in her and there's no way she'd act like this normally. Why have all your dreams turned out like this?

She hops off the bend and leans over in front of your computer, treating to an unobscured view of her panty-clad ass. It's almost as curvy as her top and she wiggles it back and forth as she searches for some porn movies, bouncing her butt with each click of the mouse. It's making you even harder than before, adding another half inch to your new length. "Here we go!" she says after a minute of searching. She turns up the volume of your speaker and then scoots back to her spot beside you on the bed.

On the screen, the title flashes by in stilted white letters, 'Family Feud.' You're momentarily confused. To the best of your recollection, you don't remember having a movie called that on your regular computer.

The first scene opens to two nubile young girls lying on a bed, wearing skimpy outfits that showoff their sweet bodies. An argument starts between the two girls--apparently sisters--about who the better fucker is and it gets quite heated, with both of them pushing and pulling each other until one pert tit gets 'accidentally' exposed in the action. The other sister can't help but become entrance with it and starts sucking on it immediately. More clothes at lost and soon the sisters are writhing around on the bed, their naked bodies entangled in a contortionist's nightmare. When they both explode into a body-shaking orgasm at exactly the same time, the younger girl declares the contest a tie. They both agree that the only way to settle their argument is to have a contest to see who can fuck the most people in the next week.

Watching the scene, you glance over at your sister to judge her reaction at seeing what the two sisters are doing, but you needn't have worried. As the scene progressed and both lost their clothes, Shelly's hand had creeped down to her panties and she was unabashedly rubbing her pussy through her panties. Well, if she's going to enjoy herself, there's no reason why I shouldn't as well.

The two of you watch the rest of the movie, masturbating side by side. The plot predictably follows the sisters as they sleep their way through friends and neighbors, raising their scores through blowjobs, pussy licking, assfucking and plain old regular fucking. The scenes were hot and you enjoyed them, but you couldn't get over the fact that Shelly had chosen this particular movie and had chosen to rub herself in front of you while watching it. It made your head spin, but it also made it harder and harder to concentrate on the movie, especially when, approximately halfway through, she pushed her panties aside and thrust two of her fingers deep into her sopping cunt. You almost busted a nut right then.

The final scene developed as each sister tried to one-up the other by targeting partners the other would least expect, their own father and brother. After a suitable period of ****--during which the horny young ladies refused to take no for an answer--the action split between the two couples, jumping back and forth as one sister received a jackhammer pounding from her daddy in his bedroom with the other let her brother shove his dick so far up her ass that his balls were almost falling into her pussy.

Beside you, Shelly begins to lose control, her fingers moving faster than you can see. She cries out, "Yes! Yes! I want it too! I want those cocks, they need to be inside me, fucking me! Daddy, please, fuck your little girl, make her cum! And my brother, his dick too, I want them all, all the dicks! Please let me fucking have them!"

Her voice turns shrill at the end and her hips lift off the bed, her orgasm sending her skyrocketing. Her chest thrusts forward and you hear a 'ping!' A button pops free from her corset, and then the dam bursts, her tits exploding free like a pillowy avalanche. Her bubblegum pink nipples are swollen with excitement, and the sight of them sets you off too. Jizz shoots in the sky like fireworks, rising high enough to hit the ceiling before falling back down, creating sticky pools all over your bed, yourself and Shelly. You almost blackout from its intensity, falling backwards onto your bed in exhaustion when you're done.

You feel the weight on your bed shift. Shelly's face appears in front of you and before you can say or do anything, she kisses you. A sweet, caring kiss as if from a lover.

And then you wake up.
