Coffeehouse AU

"I swear to God Wendy." Tambry had glanced at her phone for a minute and the redhead had disappeared. Normally she'd assume that she'd just gone to the bathroom, if it weren't for the coincidental disappearance of her other co-worker.
Tambry had never really taken Dipper for a particularly adventurous person, but after the incident this morning she was beginning to change her mind.
She'd noticed her two co-workers absence and gone looking for them. Stumbling into one of the supply closets Tambry had come upon a sight that would be seared into her consciousness for a very long time.
Wendy Corduroy, blushing furiously, was sprawled on top of one of the studier boxes, her legs wrapped around the waist of a very shirtless Dipper Pines. Tambry couldn't help but be impressed with Dipper's physique, he lacked any significant muscle mass but there were definite traces of it in his arms and back.
Tambry couldn't see the expression on Dipper's face, pressed as it was against Wendy's shoulder as he nibbled on her collar bone.
Snapping out of her momentary trance, Tambry cleared her throat.
"So... How's the five minute break going?" Wendy let out a loud yelp as Dipper straightened himself suddenly searching desperately for his shirt.
"Tambry, it's. It's not what it looks like." Wendy's excuse made Tambry snort.
"Really? Are you sure Wendy?" She leant on the door frame, "because to me, it looks like you've snuck off in your break to make out with your boyfriend, who is very much not on break."
Wendy tilted her head down, attempting to look embarrassed, obviously out of excuses.
"That's what I though. Get dressed. Both of you." With that Tambry had stormed back to the counter and gotten back to work.

After this there had been three smoke breaks and several trips to the toilets that were obviously thinly veiled make out sessions, ridiculous thin when it comes to the former, seeing as neither of them smoked.
But unbeknownst to the two young lovers, Tambry already had her revenge planned all she needed was to implement it.

It was late, Wendy knew that. She was half undressed, arms wrapped around Dipper's neck as he leant over her. Their lips met in a moment of furious passion, racking her nails down his back, making him hiss.
He leant close, placing searing kisses along her neck. It was then that she heard it, the other voice.
It was coming from all around them, getting louder and louder. It sounded like, music very familiar music.
"There lived a certain man in Russia long ago."
Dipper paused for a second "Is that Boney M?" "He was big and strong, in his eyes a flaming glow" "I think it is. Where's it coming from?" Wendy searched the room for the source of the noise. "GOOD EVENING LOVE BIRDS" Tambry's voice bellowed over the speakers that were secreted around the room.
"Tambry?" "Tambry, what the hell are you doing?" Wendy was beyond furious at her long-time friends surprise intrusion." "you made my day at work hell Wends, so I'm returning the favour. I've set up a mic in there, if you make even a hint at sexy times, back comes Rasputin." She laughed at her own cunning. "Once we've done that, I have ABBA and a couple of audio interviews with ageing Hollywood actresses, it's going to be a fun night!" With that Tambry was gone, ignoring her Co-workers anger she prepared to spend a night tormenting her friends. Karma was a bitch.
