Bring Shelly in on your secret.

You take a minute to collect you thoughts, planning the direction you want the conversation with your sister to take. If you're going to start a real relationship with her, she deserves to know about your abilities...and how she's been affected by them. At the same time, you don't want to freak her out and decide she doesn't want anything to do with a pervert like you. Plus, having an ally could be beneficial down the road.

You pull over, finding a small farm lane leading to an abandoned orchard, trees bedecked with signs proclaiming 'No Trespassing.' This is not a conversation you want to have while distracted. You turn to Shelly and you can tell she's going to begin punching you soon if your don't answer her question, her arms crossed just below her firm tits. Fuck, she's so hot, even when she's upset.

You take a deep breath. "Do you remember your dream from last night?"

Her blue eyes cloud with confusion. She shrugs her shoulders, slightly discomfited by what she does remember. "Vaguely. What does that have to do with anything?" she demands.

"You had a dream in which the two of us played a game of strip tennis, pretending to be boyfriend and girlfriend, and mom served as the line judge. She watched as we kept taking off our clothes, getting hornier and hornier until her tits literally burst out of her top and couldn't stop from playing with herself. Mom declared me the winner, at which point I chose to titfuck you as my prize. You were so turned on that you wrapped your lips around mom's nips and suckled like a little baby."

As you watch, the lost tendrils from the dream come back into focus for your sister as you describe it in graphic detail. She shakes her head in disbelief, her hands tightening on her arm with white knuckles. "How the hell do you know that?"

You rush on, not giving her time to find her footing. "Two nights ago, the night before we went to the mall together, you dreamed about walking in on me and catching me jerking off. You liked the look of my cock so much that you say down right next to me and stuffed your cunt full with your fingers. You even picked out a porno, an ****-themed one, from your collection for us to watch while we masturbated."

Shelly opens her mouth to speak, but nothing comes out as you accurately describe a scene she'd thought was only in her head. She's flustered and, judging from the rosy hue of her cheeks, incredibly embarrassed. You also notice her nipples are poking through her shirt and bra, aroused by the memories."And about a week ago, you dreamed I walked into your bedroom and pulled down my pants, showing you my thick cock. You wrapped your hands around my prick and stroked me like a whore, finishing me off with your mouth."

"How...how...how do you _know _these things?" your sister mutters, her eyes lowered, unable to look at you. She looks lost. You place a hand on her knee, half-afraid she'll pull away but although she jerks minutely at your touch, she lets it stay.

"Those were all me," you tell her.

Her head snaps up, her nose crinkled cutely. "What are you saying?" Shelly's voice is regaining its normal tone as she grapples with your discussion. "I mean, you were in all of them, obviously, but that's all, right?"

Here's the red line, the point of no return, the crossing of the Rubicon. It's now or never.

"I have the ability to enter other people's dreams and change them as I wish," you say, bracing for her response. When none comes, you push forward. "It's new. In fact, the dream in your bedroom was the first time I realized I had this...talent. But I can make people wear what I want, act how I want or look like I want. I can change anything."

"Get real," Shelly snorts. "What, you're having lucid dreams or something?"

"Kind of," you admit. "I'm definitely fully aware of what's happening in the dream, but it's more than that. I'm like a virtual god when I'm asleep." You run a hand through your hair, preparing for the next step, the piece that may convince Shelly you're telling the truth. "But there's also a...lingering effect when those I dream with wake up. That's what happened with mom this morning. She dreamed we were boyfriend and girlfriend and even participated in our naughty game. So she didn't object to anything that happened this morning, whether it was me groping her ass or you cupping the boob that had fallen out of her robe."

Your sister purses her lips, trying to take it all in. You can tell her mind is trying to come up with a logical explanation, an alternative to the scenario you've laid out for her. What you've told her shouldn't make sense. But too many pieces fit and no matter how hard she tries, she can't come up with another reason why your mother acted so sexually open with both of you at breakfast. Then she sits bolt upright as a thought strikes her.

"Is that why...did you make me like you?"

Your laugh surprises her. "No, not at all. First, I told you this only began about a week ago. How long have you had a crush on me; hell, how long have you been stockpiling **** porn on your computer. Much longer than that, right?" Shelly relaxes, at least slightly mollified by your reasoning, nodding. "Plus, while I can change how people behave in the dream, if I leave them alone, they act however they choose. I created the dreams, but it was your choice to watch porn and rub your pussy with me during the second dream, and I didn't make you do anything at all in the third. The stripping, the titfuck and the sucking on mom's boobs...that was all you, you perverted little slut."

A nervous smile splits Shelly's lips, and tension leaks from your shoulders when you see it. You feel like you've turned the corner. She seems to at least be open to accepting your dream abilities. Tentatively, she says, "I guess that would explain why I was shocked this morning but mom took it all in stride. You'd altered her attitude towards sex during the dream and it stuck with her, while I just acted normally." She giggles, catching herself. "If placing my brother's rod between my titties could be considered normal."

"I'd like to make it a normal occurrence," you joke, leering at her stiff-nippled peaks. She pinches your arm in protest.

"Listen, I know this is a lot to take in. Frankly, I still don't understand how it works or why I'm able to do what I do. It's...."

"Fucking awesome," your sister interrupts, much to your astonishment. "Just imagine what we could do while we're asleep. The places we could visit, the adventures we could have, the fucking we could do. Damn, I'm getting wet just thinking about it all. Screwing at the top of the Eiffel tower, having mom dress as a slutty maid that fulfills our every sexual whim, zero gravity fucking, an orgy with all our family and friends." Shelly shudders. "It's almost to much to handle."

You look at your sister in amazement. You knew she had some twisted kinks judging from her porn collection, but you hadn't fully understood how deeply they ran. "Holy shit, you are a major fucking pervert, aren't you?" you accuse Shelly, who winks saucily in return and tilts her blond head in a 'Who me?' kind of motion. "I fucking love you."

"I love you too!" she replies, smooching you on the cheek. She looks at the time, illuminated in green numbers on the radio between you. She sigh dejectedly. "Unfortunately, I'm already late for first period if if we don't want the school to call mom to ask why I haven't shown up at school, we're going to have to book it." She takes your hand and gives it a squeeze. "We'll need to talk more about this later. Maybe...on our date tonight."

You try to fight off a grin and fail miserably. "Tonight it is," you agree and put the car in drive.

You feel an immense sense of relief. Shelly could have been disgusted, refused to believe you or accused you of forcing yourself on her. Instead, she eventually found herself believing you, supporting you and seemingly seeing your abilities as a way to strengthen your relationship. I must be the luckiest guy alive, you think.

A few minutes away from her school, Shelly breaks the silence. "Even with your powers, I think you'll need a beard."

You cock an eyebrow at your sister. "I didn't realize you were such a fan of facial hair," you say, rubbing a line across your clean-shaven chin.

"No," she chortles. "I mean we need to find you a fake girlfriend. Somebody who you would take on dates, hang out with and pretend to be close to, all the while you're secretly giving me your cock every time you get a chance. It'll give us a cover for spending time together and deflect any attention a brother and sister might draw if they are...unusually friendly. Oh, I know! We'll get my friend, Scarlett. She's had a crush on you for years! It'll be perfect."

Your dick stirs as you picture your sister's friend, Scarlett. If Shelly's the hottest senior in her high school, Scarlett is a close second, a walking wet dream. She's half-Asian, Japanese heritage you believe, with porcelain skin that contrasts with long, raven colored hair that falls in beautiful waves, inherited from her mother. Her father, a Russian, gave her his height and curves not normally found outside of a Playboy model. She's been a constant masturbatory fantasy of yours ever since her tits grew in, and she's had a crush on you for years!? What a fucking waste.

Shelly takes a quick grope of your crotch and rubs your hardness. "I guess you approve," she says, amused. You pull into the school parking lot and stop in front of the large double doors at the entrance to the building. Your sister gathers her bag and leans in for a kiss. "I'll pave the way, let her think you might be open to dating her. And maybe we can visit her dreams tonight...help her along." Her pretty blue eyes are positively devilish.

She climbs out of the car and you watch her ass sway as she runs into the school. Shaking your head, you pull away from the curb and head toward the University campus. You have an appointment to keep. Maybe you'll finally be able to get answers of your own.
