A nightclub party.

It’s dark, but different colored lights flash all over the place, and loud music threatens to make you deaf. Even though you’ve never been to one, you know this is a nightclub, and the party seems to be at its peak.

While you see a lot of people, all their faces are blurred out. What’s more, you recognize they’re wearing clothes that can generically be considered “party clothes” but it’s hard to tell. You remember reading that, unless it’s important for the person dreaming, very few things are detailed in dreams. So to Shelly, the fact that there're people here partying is more important than who they are or what they’re wearing.

Finding your sister is surprisingly easy among this crowd. It’s like something guides your steps as you walk. It’s unsurprising, however, that you find her dancing her heart out, glass in hand and surrounded by what you assume are her friends, since two of those girls have detailed faces. There’s a brunette and one with long black hair.

You start walking towards her, and you’re shocked when Shelly grabs the back-haired girl by the arm, pulls her closer and kisses her full on the lips, shoving her tongue inside her mouth. Both girls embrace each other, kissing deeply and passionately before pulling away and laughing like it was the funniest thing in the world.

Even though this is a dream, your dick hardens at the sight. You quicken your pace and you’re next to her in seconds. Shelly notices you and turns around from her friends.

“Hey, bro! What are you doing here? You hate parties!” She says, surprised, yet the smile doesn’t leave her face. It’s weird seeing her smile at you, but she’s having too much of a good time.

“I do, but I wanted to hang you with you.” You tell her.

“Really? That’s great! Come here then, dance with me!” She wraps her arms around your neck and pulls you closer to her.

What the-!?

Shelly is a bit taller than you, about half a head taller. She’s wearing a white tank-top with thin straps, so she’s showing a lot of cleavage.

She presses her whole body against you as she dances, grinding herself against you. Your faces are close, but you still need to look up to her. Her amazing chest presses against you, making you both uncomfortable and excited.

Before you know it, your hands are on her hips, and you’re matching her movements, not being very subtle as you poke and grind her crotch with your hard-on.

What the fuck?

You are very confused right now. Not by the close proximity with you sister, but by the fact that you’re going along with it, even though you can’t fucking dance. You hate it, you never do it. But now? You’re pressing your own body against your sister, matching her move for move.

“Oh my! You can actually dance!” Shelly says, surprised but with a wide grin. “You’re very good at it, too!” She says as she grinds back against your crotch.

Wait, you remember something about this. You read that, if you leave your guard down, it’s very possible you become another part of the person’s dream. That means that your actions and words are dictated by the dreamer.

To regain control, you have to focus on yourself, the person you really are. At least, that’s what the books said.
