|~Dippers POV~|

"Bill just chill here in the corner for a bit if you think it's that stupid but I want to try and enjoy this party. Just drink some punch I'll be back in a few minutes to check on you." I walked away and looked around for Mabel. 'Jesus it's been 4 years since he came back but he's still a child'
Bill came back asking for forgiveness the next summer we came back. Of course we were skeptical but after a couple of months we realized he was serious and we all became pretty good friends with him. 'It's just too bad he's even more childish than before' "DipDop!" I turn around and see Mabel running towards me. "There you are bro bro! I was beginning to think you weren't gonna show up!" I laughed and hugged her," Of course I would! You're the only persons parties I go to you know that."
Mabel's favorite song came on and she dragged me out to the dance floor. 'Somebody save me I hate this song.'

|~Bill's POV~|

'I can't believe he just left me in the corner like this!'
I decided to just shrug it off and go get some punch like he said. "It's not my fault Mabel's parties are too boring for me." As soon as I took a sip I noticed the weird taste. "What kinda punch is this? Whatever it's still pretty good."

-time skip-

Woah everything is spinning! I had like 7 cups of the punch what's going on? I started giggling and realized someone spiked the punch bowl. "Oh well haha enjoy it while it last!" I chugged down another cup and started walking through the crowd to find dipper. I started giggling like an idiot every time I tripped or stumbled. I found dipper and saw the button up shirt he was wearing was unbuttoned and showing some of his chest. I felt myself blush. 'He's so...sexy. And so much cuter without his hat on.' I started walking towards him and wrapped my arms around him from behind. "Hello my little PineTree~"

|~Dippers POV~|

Mabel convinced me to drink 3 cups of punch. 'Now I'm tipsy. Can't believe I didn't realize it was spiked sooner.' I was a slightly giggling mess but I was able to relax a bit so I guess it wasn't too bad. "Hello my little Pine Tree~" I felt Bill wrap his arms around me and I felt myself blush. "B-Bill are you feeling okay?" He giggled and nuzzled his face into the side of my neck. "I..feel hehe amaaaaazziiinnnnggg! And you," I felt him kiss my neck ," look sooo sexy right now." I blushed even more as he pushed himself against my back. "B-Bill you're drunk. Y-You should r-really go lay down." He continued peppering tiny kisses along my neck before answering me. "Only if you come with me~"
A shiver went down my spine and I could definantly say that turned me on. "W-Whatever gets you to bed. Let's go." I got him off my back as I grab is hand and lead him up to the attic. "I'm so glad me and Mabel don't share a room anymore."

As I closed to door to my room I suddenly got slammed onto my bed. "WHAT THE HE-" My yelling was muffled by a pair of soft, warm lips against mine. I relaxed and slowly kissed back, and as bill pulled away I saw a blush dust across his face. "I've wanted to do that for the longest Pine Tree. I know you probably hate me now." I giggled and shook my head no. "I'm glad you did," I moved closer to his lips," because I've wanted to do that for longest too." I softly kissed him again and I felt him smile with me. Our kiss got rougher and I felt his hands slowly unbuttoning my shirt and I started working on his. I moaned as he roughly bit my bottom lip and my hips thrusted upwards towards his earning an even louder moan from both of us. His tongue entered my mouth and he was gently rolling his hips against mine. I finally peeled his shirt off and slowly admired his chest and stomach with my hands, worshipping his body. He slid my shirt off and separated our lips, both of us breathing heavily. I got a good look at him and I presume he was doing the same to me. I blushed as I realized what was really happening here. "B-Bill your drunk. A-Are you sure you wanna do this? I-I don't want to take advantage of-" he cut me off with a quick and passionate kiss. "Of course I do Pine Tree." He whispered in my ear," don't worry I'll be gentle. If you want me to stop at anytime just let me know."
I nodded and we began kissing again as I slowly worked my way to taking his pants off.
By the time we both got each other's pants off we were a panting blushing mess. He moved down to my neck, kissing, licking, sucking and earning no complaints that's for sure. "B-Bill~ Harder, suck harder~" He simply smirked at me and obeyed my wish. He made his way to my nipples and I let out a loud long moan. "Bill, fuck right there yes right there!" My back arched towards his mouth as I gripped the sheets, panting. He pulled away and I whined as I sat up to look down at him. "My my Dipper I didn't know you would beg so much~ but I'll give you something much better I promise~" he moved downwards and slowly peeled off my boxers. I blushed as my hard cock sprung up as it was released from my boxers. As he slowly licked my tip, I moaned and gripped at the bed sheets, my back arching. "Shiiiiiit bill do it again, do it again!" With how loud the music was down stairs I had no worries about being loud. He looked at me with that devilish smirk of his and he took me into his mouth completely with no warning. My mouth opened wide in a silent moan as I was over come with sensation. He slowly started taking me in and out of his mouth. "B-Bill faster go faster!" I felt my hips thrust upwards and I felt his moan vibrate all over my cock. "S-Shit bill I'm close!" I grabbed the sheets harder than I had earlier. Right when I felt I was about to explode he pulled off quickly. I sat there panting and frustrated. "Oh pine tree I'm not gonna let the fun end so soon~" he pulled off his boxers and spread my legs. I blushed and tried not to cover my face in embarrassment. "Now I know you have lube somewhere in here. Mind telling me where it is?" "It's under my pillow."
He leaned over to grab it and made sure to leave a hickey or two on his way back. As he slicked up his fingers it hit me. 'I'm a fucking virgin. And I'm letting Bill Cipher take my virginity. I'm strangely okay with that, because at least I know he'll stop if I don't want to go any further.' I felt him slowly push a finger inside me. I winced in pain and he stopped to look at me. "Are you okay?" The concern in his eyes assured me. "I'm fine keep going." He smirked and nodded.

By the time he had three fingers in I was a sweating, panting and moaning mess. "Put it in just put it in already." I felt him pull his fingers out. I bit my lip as I watched him slick up his cock with lube. "If we ever do this again you better let me blow you." He looked surprised at my comment but laughed and nodded his head. "I would definantly enjoy that." He lined up with my entrance and made slow soft circles on my hip as he slowly pushed. I gripped the sheets at the sudden pain. As I started panting, Bill leaned forward and whispered in my ear," You look so sexy like this, just laid out in front of me. Squirming at my every touch. You love this so much don't you?" I moaned at his words and nodded my head. He slammed the rest of his way in and continued whispering to me. "Your such a slut pine tree. Begging for my cock, moaning and whining like a bitch in heat." He began thrusting in and out of me quickly. He found a spot that made my vision go white and I'm pretty sure he noticed with the way my back arched off the bed, my eyes rolling back into my head with the loud scream I let out. "Tell me how much you love it. Tell me how much you love having me slam inside of you!" He slammed especially hard at that last statement and I couldn't help but feel compelled to answer. "Yes! Yes I love it! Love your huge cock filling me up inside!" He kept going faster and faster. "Who do you belong to pine tree?" I could barely respond between my constant moans. "You! I belong to you!" I was getting so close and with the way bill was thrusting I'm sure he was too. "Say my name Dipper~" he left hickeys along my chest and I could hold back anymore. "BILL!" I felt myself explode all over my chest as bill kept thrusting into me. For a good minute I couldn't see anything.

When I finally came back to reality Bill had laid down next to me and we were both spent and tired. I blushed as I recalled the whole event. Bill suddenly pulled me to his chest and cuddled with me. "When I wake up tomorrow, promise you'll still be here." He was barely keeping his eyes open. "I promise bill. Now get some sleep. I'll be here when you wake up." He closed his eyes as I kissed his chest. I covered us and slowly fell into a deep sleep.

|~The Next Morning~|

|~Bills POV~|

I woke up with a headache and my whole body was aching. I looked down to see dipper snuggling into my chest. Memories of last night came rushing back and a soft smile spread across my face. "You kept your promise." I leaned down and brushed his bangs away so I could kiss his birth mark. He slowly woke up and I saw the confusion cross his face before it was replaced by embarrassment. I laughed quietly and kissed his lips before any questions were asked. He smiled into it and as we broke apart I could see how happy he was. "Let's take a shower and get you into some clothes my little pine tree." I picked him up and he laughed. "I'm not a girl I can walk ya know!" "I know but I like carrying you!"

I teleported us back into the room after our fun shower and set Dipper on the floor. His knees almost buckled so he sat on the bed. "Holy shit my ass hurts." I laughed. "Well duh! Why do you think I wanted to carry you?" He blushed and looked away. I smiled and grabbed one of my sweat shirts and some of his shorts and underwear. "Here go ahead and get dressed while I get my clothes." He looked at me like I was crazy. "I-I'm not changing in front of you!" I gave him a bitch face that would put Sam Winchester to shame. "I've seen everything there is to see dipper no need to be embarrassed. Besides I'm gonna be looking through the closet." He sighed in defeat and got dressed.
After we got dressed I sat dipper on my lap and brushed through his hair. "So dipper, considering last night does that mean your my boyfriend now?" He blushed and nodded," I guess so bill. But I'm gonna hate Mabel finding out." I looked down at him confused,"Why? She likes me your whole family does. What's the problem?" He groaned loudly. "The problem is she's gonna start fangirling and taking pictures non stop." I laughed and hugged him closer. "As long as your mine I don't care."
