Thank you guys so much for reading my first Fan Fiction, and I hope you'll stick around to see the ending... And yes, this story will be going for a while, I have plenty of ideas. But if you want to give any input to future developments, feel free to post a review.

But I digress, let's see what happens to Dipper and Wendy...WARNING: This chapter does get a little intense.

Dippers POV

I watch Wendy fall onto her back, spreading her legs to reveal her red panties. She thrusts out her chest to accentuate her curves, making me gulp.

"Come on Dipper," she says in a soft voice, "Come over here and show me what you got."

I smile lightly and pull my shirt off. I then call down onto Wendy's body and go for the buttons on her shirt. She happily allows me to tear it off, revealing her red matching bra. She looks so beautiful, the way her red hair cascades down her shoulders and slightly onto her torso.

"Wendy?" I speak up, "I've been dreaming of this moment since I was twelve, and not that it's finally here..."

"Yeah Dipper?" Wendy asks me, sounding a little nervous at my statement.

"Now that we're here... I want you more than ever." I choke out, unsure if it was the right thing to say. But she just responds by unhooking her bra from the back, and grabbing my hands, placing them on her cups. Her eyes seem to smile into mine, and I take hold, and relieve her of her undergarment. What I find is a set of beautiful breast, much bigger than I had imagined. And coupled with Wendy's face, it sets off a stirring in my chest again, but I soon ignore it, and place my hands on her chest.

"Alright, now show me what your sister has taught you." Wendy coyly commands.

I start my rubbing my palms into her chest, before using my fingers to squeeze. They feel very soft, still bouncy. Wendy starts moaning in enjoyment. I look up at her face and see her head back, and her eyes closed, relishing in the moment. My fingers make their way to her nipples, and I stars lightly rubbing them. Wendy gives me a barely audible gasp, and continues to let me pleasure her.

I start to lower my hands from her breasts, and make my way to her stomach, passing it and arriving at her underwear. Wendy sits up and places her hand on my shoulder, making me look up also.

"Talk dirty to me Dipper." she sensually asks.

"What?" I reply in confusion.

"Talk dirty." she repeats. Where is she going with this? I ask myself as I try to think of something to say.

"Uhh, you're a bad girl?" I awkwardly say. This makes Wendy giggle a bit.

"Keep going." Wendy says as she sits on her legs, turning a little to the side.

"You're a dirty girl." I say, getting a little into it. I'd never done anything like this before, but I was getting the hang of it.

"Yes I am," she says as she gets onto all fours and turns around. "Punish me Dipper." She says with a small lick of her tongue. I gulp hard, as she points her butt at me. I fur up my brow, and pull my hand up. Then, I come down hard on her right cheek, giving her a good spank. Her butt feels as soft as her breasts, and after my spank her cheek turns a little red. She moans in pure bliss.

"Do it again." she tells me.

I give her another good spank on her other cheek, to which she happily replies, "That feels good. But now, it's your turn."

"Wendy, please don't be too rough on me. I'm fragile." I try to convince her. She just pouts out her lip, sighs, and agrees. Wendy grabs hold of my boxers and pulls them right off, throwing them onto the floor. I'm already hard, and Wendy happily takes hold of my warm member. I flinch at the feeling, and also the fact that Wendy, of all people, is holding onto me.

"If your forehead has the Big Dipper," Wendy says, slowly rubbing me, "then this must be the 'Little Dipper', huh?" She giggles girlishly at her remark, and starts to speed up her rubbing. She also cups my balls with her free hand, carefully massaging them. This feeeeelss amaaaaazing...

"Now Dipper," Wendy says, stopping her rubbing for a second, "you've never been inside Mabel, have you?"

"What?" I ask, snapping out of my trance.

"You know... You've never been, inside her?" Wendy points at my Little Dipper as she emphasised 'inside'.

"Oh, you mean-"

"Yeah." Wendy cuts me off, getting impatient.

"I guess not." I tell her.

"Well..." Wendy looks away, embarrassed, "I've got some condoms here."

"Wendy? What are you saying?" I ask suspiciously.

"Dipper!" she says loudly like she's talking to a child, "I want to have sex with you!"

Did I just hear that right? Did Wendy just say she wanted me to- yeah she did.

"Umm..." I try to say, but my heart feels like it's tightening in my chest from being so scared. "I don't know, I've never done this before."

"Well, neither have I," Wendy says, "so it'll be a learning experience for all of us." I smile at that, and Wendy smiles back. She then reaches behind her and opens the draw in the bed side cabinet. I see her pull out a box labelled: "Trojan". As she removes a condom packet, I briefly reflect on how my summer has turned out so far. Mabel telling me she loved me, and feeling me up at night. Then again in the shower. And now, Wendy tells me she kind of likes me too, but now, she wants to do me.

"Alright, put this on." She hands me the condom. I look down at it, and back at her.

"You dirty girl." I say with a smile. I slip it over my full erection, and get onto my knees, and Wendy pulls off her panties. We're both fully naked now, and I pull her body closer to mine, inserting my manhood into her pink. I then start pulling it in and out, as I believed you were to do. Wendy is really enjoying this, and so am I. We do this for about twenty minutes, before Wendy decided to flip onto her stomach, and pushing her butt out towards me again. I get the hint and insert myself into her hole, making her moan once again. We go in and out for about another twenty minutes before we're both tired from the pleasure. We flop onto our backs, out heads turned to each other. Wendy pulls me in and plants a large kiss on my lips. I respond with and awkward smile.

"That was really great." Wendy tells me, still panting from out session.

"But remember, you can't tell anyone." I remind her. She rolls over so she's laying on her side, towards me. She rests her head on her arm, and her other arms at her side.

"I promise."

There. I wasn't going to include this chapter in my story, but I figured it was what you guys wanted to see. Sorry if it wasn't, but don't worry. Next time will be different. Stay tuned.
