For the prompt "It seemed like a good idea at the time" on qaf_prompts. Just a little humor and Justin and Brian playing around. I think it's set in season one, maybe season two.
Brian heard the crash while he was still in the elevator and groaned. Fucking teeny bopper twinks. He opened the loft door and stepped inside. His couch was flipped, resting on it's back, the legs out to the side, all the cushions strewn about the floor. Daphne was sitting on the back of the couch like it was a seat, laughing her head off.
Justin was standing at the kitchen counter, holding a handheld eggbeater in his hand. He was cracking up, too, pointing at a pile of what looked to have been cake lying in a heap on the floor. Unfortunately, the eggbeater was still on, and the rotating whisks were flinging gobs of chocolate—what is that, icing?—everywhere.
"What exactly are you doing?" Brian asked, frowning.
Justin stopped giggling, but turned glazed, laughing eyes to Brian. Brian cursed the baby blues and the power Justin's sunshine smile had over him. "We found your stash Brian. We were trying to make hash cake. It didn't work." The two friends broke out into giggles again.
Brian pulled off his tie and began to unbutton his shirt. "So I noticed. You two are going to clean this up."
"Mmhmm." Justin seemed to suddenly become very interested in the exposed skin of Brian's chest. He stepped over to the brunette, eggbeater still in hand. It came unplugged from the wall and brought a (thankfully, closed) box of powdered sugar to the floor. "Try this," Justin implored, sticking a finger full of icing in Brian's mouth. It tasted good. Brian licked it off, sucking at Justin's finger. He knew he'd regret it, but it tasted good, and stoned Justin was always both entertaining and horny.
Justin's eyes grew dark, and he smeared another fingerful of icing on to Brian's chest, licked it off. Daphne giggled from the couch. "Yum," Justin licked his lips. Then he attacked Brian's mouth with his own. Brian couldn't help but tug the twink to him, helping the blonde tug off his shirt. In the back of his mind, he remembered that Daphne was still here, and that she would be getting a free show, but he realized that he must be getting a second-hand high, because he really didn't care.
He backed Justin toward the bedroom, ignoring a still-giggling Daphne, and took a finger of chocolate of the beater that Justin still held, smeared it on to Justin's nipple, and licked it off. Justin moaned.
"Fuck me, Brian." Brian shoved the twink onto the bed and did as he asked.
The next morning, Brian got up, shoving his hands through his hair, eyes still closed, and promptly tripped on the eggbeater still lying on the floor.
"Fuck!" he held his foot, grimacing. He heard Daphne's "huh?" of awakening. She had passed out on the back of the couch, probably not long after Justin. Brian pinched the bridge of his nose and turned to take a shower.
After his shower, he felt more awake, and went to get some coffee. Justin trudged out, eyes still half-closed and blood shot, stuck his hand out in a request for coffee. Brian handed the mug to him. After he had woken up, Justin looked down at himself and started to laugh. He was covered in streaks of chocolate. He stretched the front of his boxers and checked his cock. It was covered in sugary chocolate residue. He laughed harder, which made his hangover worse. He held his head and giggled.
"Hash cake, Justin? Seriously?"
Justin shrugged, still smiling. "Seemed like a good idea at the time."
