After trying to get Mabel to choose between being straight or bi she swore to never talk to her it's been three years since that day and Mabel and Dipper and Pacifica were now sixteen and Brain was now seventeen
Mabel was sitting with her boyfriend Brian, on his porch swing relaxing enjoying the cool summer's night she was in complete bliss right now she intertwined her fingers with his and continued their silence Brain then tapped her shoulder and she looked at him
"Hey." He said
"Hey." She said back
"Whatcha thinking about?" He asked
"You." She said Brian then lifted her chin and kissed her.
"Hey, you know it's been three years since we started dating." He said
"Oh really, I haven't noticed." She jokingly said kissing his cheek
"And you know I have been meaning to ask you something." He said
"What is it?" She asked
"Um well, I just wanted to tell you that well I love you." He said Mabel then smiled and wrapped her arms around him
"I love you too." She said back the two were about to kiss again till she heard her phone go off. "Sorry Sorry, I thought it was on silent." She then excused herself and saw that it was Dipper, she groaned and answered it.
"What is it Dipper!" She barked through the phone.
"Easy, I was just calling to tell that I'm going to be out of town with Pacifica, apparently she has a family thing and she wants me to come with her and Mom and Dad are going to be for the weekend for a honeymoon so you have the house to yourself." He said Mabel was on the other end was silent and screaming internally.
"Mabel you there?" Dipper asked
"Huh, yeah I'm here." She said
"Oh, and Mom said you can invite a Brian over but only during the day." Dipper said
"Don't worry Dipper, I'm responsible." She said looking over a Brian.
"Okay just so you know I vouched for you don't make me regret it." He said hanging up, Mabel then walked back to her boyfriend and sat in his lap.
"Hey I have my house all to myself for the entire weekend, so it'll be just me all on my lonesome." She said Brian knew what she was hinting at but decided to play along.
"Oh no, that's bad maybe a loving boyfriend should come over sometime and keep her company." He said as he cupped her cheeks and kissed her. "So see ya Saturday?" He asked
"Definitely." She said as she got off his lap. "Care to walk me home?" She asked
"It would be my pleasure." He said and they walked to Mabel's house hand in hand as they got there Mabel was about to opened the door till she was faced with Pacifica straightening her hair.
"Oh Mabel, I was just picking up something for Dipper I'll be leaving." She said looking down leaving the house.
"Mabel when are you going to forgive her?" Brian asked but Mabel remained silent "it's been three years plus she was the one that got us together." He said
"Good night Brian." Mabel said before closing the door leaving Brian in a sadden state
The Next Morning
Mabel heard the sound of tapping on the window she the blinds and saw Brian with a white and orange bag and two coffees in a cupholder, she mouth 'come through the back' and closed the blinds she then grabbed her robe and raced downstairs she looked in her parents room to see that they were gone, she smiled and let's Brian in
"Are you crazy coming this early?" She asked
"I just thought with your parents out of town you could use some breakfast also there was some guy around here so I chased him off.' He said
"Uh, that creepy stalker." Mabel said but it was soon a memory as smelled the rich aroma of eggs, sausage, cheese, potatoes, and bacon.
"You got me my usual breakfast burrito." She said as she kissed his cheek she unwrapped the yellow paper and began eating.
"So what's the plan for today?" Brian asked
"Well I was going to hang out with my people, patrol the mall for some new clothes usual girl stuff." Mabel said
"I didn't hear hang-out with my boyfriend at home." He said
"Oh well, I just thought… look about last night."
"Save it, that was a sensitive topic that I shouldn't have brought up." He said
"That's why I love you, you understand me." She said as she kissed his cheek and continued eating her burrito she then looked at Brian
"Aren't you going to eat?" She said as she sipped her coffee.
"Oh, I alright ate." He said sipping his coffee."
"Well don't you just stare why don't you go watched some tv?" She said
"I'm waiting for you, I thought we watch some Netflix and chill." he said
"Brian!"
"What? Did I say something wrong?" He asked
"Do you even know what that means?" She asked
"No a friend of mine suggested it." He said
"Brian "Netflix and Chill" is slang for well…" She whispered in his ear and he began blushing
"Oh god, I'm so sorry I just though we just watch something on Netflix, not that." He said
"It's okay Brian and besides, I would rather chill then watched Netflix." She said with a blush which made him blush as well the two then sat in silence till Mabel finished her burrito.
"Well I better get dress for the day, would like to help me?" She offered but Brian kindly denied, he was now waiting in the living room watch a stand-up comedian when Mabel walked down in a plaid skirt with black short leggings with a white dress shirt under a black sweater vest that hugged her curves.
"Okay, what's up with the schoolgirl look?" He asked
"Oh, I'm going to get back at the stalker because I know that he is a major otaku." She said
"You do realize that I'm an otaku right." He said
"I know that's how I know it's working." She said before walking out the door.
Few hours later
Mabel came in with Brian close behind her they sat down on the couch Mabel was laughing and Brian had an irritated look as they sat down on the couch.
"Man that way a fun day." She said
"Mabel I don't think you should have teased that boy." He said
"Hey that guy was a stalker and he deserved it." She said
"I know but did you have to flip your skirt causing him to pass out at the sight?" He asked
"Oh come on you get to see more than just underwear." Mabel said
"Look can we just relax and forget about today?" He asked
"I know how we can relax." She said removing her leggings she then climbed on top of Brian and started kissing him, but something didn't feel right about this, to her it felt wonderful and kind of distasteful but she always kissed him but not with sexual desires she then stops and climbs off him.
"What's wrong?" He asked
"I uh think am not feeling good I think ." She said
"Oh well, I guess I'll be on my way then, hope you feel better." He said before leaving, Mabel then went upstairs and went to her room but stop at Dipper's door she opened and grabbed a picture of Pacifica and sits down on the bed she stares at the picture of her and pulled down her panties and started fingering herself she then unbuttoned her shirt and started massaging her breast she then props the picture up and started masturbating her fingers explored insides as she stared at the picture of Pacifica.
"What are you doing to me!" She said as she added another finger inside her she then pinched her nipple she then looked over to see Pacifica's panties she grabs them and held them to her nose
"What is wrong with me I love Brian but Pacifica she…. She completes my love." Mabel thought as she cummed on her hand she fell back and started breathing heavily she picked up the picture and kissed it.
