Dipper POV

Our annoying Grunkle collected the money and flowers from tonight's show. I placed the boquet Alex threw at me on the windowsil, well tossed it actually.

Mabel hugged me from behind, her hands running down my chest.

"So magic man, ready for your big performance?"

She kissed my neck swiftly, and bit it. We're closer than siblings, no doubt about it, but we don't leave marks. Unless we say it's alright.

Tonight, was one of those nights.

I turned around and embraced her, resting my head on her shoulder as she did the same.

"I love you sis, I don't give a DAMN what people say about us being so close."

Only, no one suspects, yet.

We've always had the feeling that we're being watched, but we more than happily took the risks. That, and there's a trick up our sleeve, Will.

He keeps a watchful, eye on us, pun intended. Luckily we're always alone in our room, and Stan never comes in here.

"Neither do I brother dear. Now, LOVE ME WITH EVERYTHING YOU GOT!"

She took her headband off, and I followed suit with my amulet. Mabel pinned me against the wall, fiercely kissing my neck. She loved teasing me a lot, but what I loved more, was doing the same to her.

"M-Mabel! D-don't stop! Please!"

But she did exactly that, and slipped off her heals and leggings. I unbuttoned my shirt, carelessly tossing it on the floor.

"Wow, you're getting more defined."

"As are you sis."

"Watch it there, bucko."

My lips latched to her neck as she moaned my name.

"Ooohhh Diiiperrrrr! Do this to me every day!"

I licked each spot my lips touched.

She inhaled sharply, holding my face.

"You sure know how to satisfy me."

Her hands pushed me towards her bed, I sat on the edge. She slide onto my lap, wrapping her arms around my neck.

"L-leave a mark on me. Prove to the WORLD I belong to no one else but you!"

"As you wish."

I began kissing her neck again, slowly sucking her soft, tender skin.

Mabel moaned in ecstasy, and began rubbing herself against me. Her movements caused my teeth to bite her a little, which I didn't intend to. She yelped a bit from the pain. I moved away and saw a little blood on her neck.

We looked at each other for a moment.

"Don't waste it." She said firmly but still filled with lust

I licked her neck, healing her wound. The satisfied moans from her lips filled my ears once again.

"That's enough, brother."

I slowly licked her neck one more time, letting my tongue linger on the wound, then slowly retract it.

"Ohhhh brother, you're the best!"

She slide off me, unbuttoning her shirt. I slipped off my shoes, dress socks and my jeans.

We were both now in our undergarments.

'Mabel Gleeful, the only Goddess in my life.'

"What was that? I can read your mind you know. But say it anyway."

"Mabel Gleeful, you're the only Goddess in my life. I'll always love you."

"How sweet of you brother dear."

I reached around her, and unhooked her light blue bra. She put her hands over her chest, teasing me. Always doing what she does best.

"It's true."

She took her hands from her chest, leaning me over, and positioned herself on top of me.

"Good, NOW HUMP ME WITH ALL YOU GOT!"

She didn't need to tell me twice. Her hips moved with mine, I thrusted upwards with her. Mabel's boobs have gotten more, defined over the years for one thing. With each thrust we did, they bounced up and down rhythmically. We soon got a good rhythm going, our, well mostly Mabel's moans filled our room.

"D-DIPPER! I-I'm gonna cum! Oh don't stop! DON'T YOU DARE!"

"MABEL!"

We both climaxed, our underwear were soaked beyond recognition. She collapsed onto my chest.

"D.....Dipperrrrrr. You're amaaaazing in bed. I'm not letting ANYONE take you from me. If another girl so much as LOOKS at you, they're history."

"Understood sister dearest, understood."

"Good. Hey, if you ever wanna do this again sometime, sayyyyyy, before one of our next shows, just let me know." She said

I nodded.

"I'm all sweaty and gross, I gotta take a shower." She said getting off me

I quickly got up and lightly smacked her butt.

"Only if I can come with you." I said hugging her from behind smirking deviously

My hands trailed from her breasts, down to her stomach and I started rubbing her through her panties.

"Not even a question." She replied

We quickly kissed as we made our way to the bathroom.
