Hi guys! Thanks for the awesome reviews. And remember, if you have ANY ideas for what the two can do in the future, let me know in a review. Okay, enjoy!

Mabel's POV

It's been about a week since I finally got Dipper to be my boyfriend, and now I want to have some fun with him. I've got a whole list of things I want to do, and I'm just going to go through them one by one. My only concern in that Dipper will comply with my plans... But, if not, I can always get him on board with my feminine wiles. A small smirk grows upon my face as I lay on my bed after dinner. Dipper is washing the dishes, and afterwards, he's going to have a shower, like he usually does at this time of night. Then, I can put my plan into action. I suddenly hear Dipper coming into the attic.

"Hey Mabel." he says with a slight sigh.

"Hey boyfriend!" I coyly declare. I jump up and plant a large smooch on his face, and Dipper pulls back, obviously surprised. "What's wrong Dippy? We can kiss you know."

"Yeah, I know. I'm just not used to it yet." he admits rubbing the back of his neck, standing a little to the side.

"Well get used to it." I say grabbing his hands and smiling at him.

He stand there for a few seconds before Dipper pulls away and grabs his pyjamas off his bed.

"I gotta take a shower." he says to me, and slowly walks out of the room.

Okay Mabel. Now, we wait. I think to myself as I try to listen out for the water of the shower. Soon, I hear the water hitting the ceramic bathtub and I know it's now or never. I jump up and rush downstairs to the bathroom, and carefully open the door, trying not to give myself away. Dipper is quietly humming to himself as he rinses off, and I close the door behind me, and begin to undress. When I'm fully naked, I pull back the shower curtain and shout "Hey Dipper! Room for one more?!"

"Agghh!" Dipper screams, frantically trying to cover his privates, "What the heck Mabel?! What are you doing?!" He's looking at me up and down, staring at my fully exposed breasts.

"Oh, you looking at these?" I asks as I bend over and squeeze them together.

"Mabel, you can't be doing this. What if someone sees us?" Dipper worryingly asks.

"Eh, don't worry about it. It's just you, and me." I say with a big smile on my face. "So come on, put your hands down."

Dipper becomes aware that he's been covering himself the whole time, and slowly lowers his hands. I look down to his, what I like to call: 'Little Dipper', and see that it's fully erect.

"Ooo. Someone's excited, huh?" I mockingly say.

"Shut up, it's just because you jumped into my shower naked." Dipper firmly replies.

"Come on Dipper, calm down." I reassure him as I grab his left hand, "Put your hand on my boob." I lower his hand onto my chest and he starts squeezing it gently. "Feel good?"

"Uhh, yes." Dipper nervously says, not taking his eyes off his hand.

Dipper's POV

Oh my gosh, oh my gosh. I'm touching my sister in the shower, and she's loving it. I look up to her face and see that she has her head back and her eyes closed. With a gulp, I raise my other hand to her other breast, and keep squeezing and moulding it in my palms. This is so weird. I've never done this before. Is all I can think.

"Mabel?" I manage to squeak out.

"Yes Dipper?" Mabel asks, moaning softly.

"Um, is this good? Am I doing it right?"

"Mmmm, yeees..." Mabel sighs.

Mustering up my confidence, I decide to step it up a notch and begin rubbing her nipples with my fingers. She lets out a moan of satisfaction. She giggles and looks straight at me with a evil look on her face.

"Okay hotshot. Your turn." she whispers. Mabel bends over and grabs my manhood and begins slowly rubbing it, just like she did the first night she felt me up. A surge of adrenaline rush through me filling me with a strange feeling of bliss. I'm only thinking about that feeling Mabel is giving me in my nether regions.

"Ma-abel." Is all I can muster out of my lips. Mabel slowly lowers her head down and I suddenly become aware as to what she is doing.

"Uh, Mabel." I say, blocking her mouth with my hands, "I don't think we should go that far yet. I'm really not comfortable." She looks up at me with sad eyes, obviously trying to convince me to let her... um... do that. "No Mabel." I tell her, like I'm talking to a dog, with a slight smirk on my face.

"Fine..." she signs, looking away from me, upset at her failure. I can't help but feel a little guilty. But it was too much letting her touch me down there, and I can't let her cute face get the better of me. I reach past her and turn the water off, and step out of the shower to dry off.

Mabel POV

As I watch Dipper leave the shower, I can't help but feel pleased with myself for my plan working out more or less how I hoped. I got Dipper to touch me, and I managed to get to his junk. But I'll have to try harder to get it in my mouth. Oh gosh, what am I thinking? I'm so weird. Is all I can think. I look back over at Dipper and see him pulling his boxers up over his butt, and turning over to face me, still in the shower.

"Well?" he asks me, "You coming?"

I just stare into his deep brown eyes, stand up and walk over to him, placing my hands on his bare chest. I lean in and give him a small peck on the lips. He is put off for a second, and turns his head to the side, looking a bit embarrassed. I grab my towel and wrap it around my body, and turn the handle on the bathroom door. I give one last smile to Dipper, silently telling him I enjoyed our shower together. Then, I open the door, and left. This is the start of a beautiful relationship.

Well, I guess that's it for now! And remember, let me know what you want to see next. If I like it, I might put it in my next chapter. Thanks for reading!
