It's a hot summer evening in Jump City. Beastboy and Robin are sat across from each other at a diner booth. The table was a mess of crumpled napkins and greasy plates. The two boys had just finished an array of burgers, nachos and chili cheese fries. Beastboy reclined back into the booth and let out a loud burp.
     "Oooh god, that was so fucking good." Robin nods in agreement.
     "Yeah, this place always hits the spot." A few minutes passed as they waited for the waiter to bring the check. A deep gurgle came from Beastboy's stomach.
    "Awe dude, I think I ate too much." He rubbed his stomach before a massive wet fart blasted against the seat cushion. It was heard by everyone at the diner and the raunchy smell quickly spread through the air. Beastboy snickered. "Fuck that one was beefy." Robin chuckled and waved his hand in front of his nose.
     "Jesus dude, people are trying to eat. Better hope we make it back to the tower before you shart yourself." The patrons glared at their table and groaned in disgust. The waiter came soon after and the boys paid for their meal.
     They walked out of the diner and started going down the bustling sidewalk. A few minutes passed walking in the humid summer heat. Beastboy pulled on the collar of his tight uniform.
     "Damn, it's hot. I'm sweating like crazy." Robin snickered.
     "No shit, I can smell your pits from here, I think everyone on the block can." Beastboy smirked.
     "Yeah well, they'll be wishing for my pit stink when they get a whiff of this." Beastboy stopped walking and got into a squatting position. There were groups of people on all sides of them. He grunted and released a huge bubbly fart that lasted for several seconds. Everyone around them gasped at the abrupt sound and the people south of his ass began to shield their noses as they hurried around them. Robin laughed.
     "Nasty dude. Your ass is a biohazard." They both chuckled as Beastboy fanned behind his butt.
     They continued down the street, Beastboy ripping ass every couple of blocks. His dick was starting to get hard in his uniform.
     A few minutes later Robin tapped him hard on his shoulder and pointed across the street. It was a small convenience store and through the window you could clearly see a man with a gun shouting at the cashier. The two heros nodded at each other before running across the street and into the store.
     The man holding the gun looked to be in his mid twenties. He had short blonde hair and pale skin and was wearing a pair of jeans and a tattered black T-shirt. Once he noticed the door opening he quickly aimed his gun at the two titans.
     "Stay back! I'll fucking shoot!" Robin picked up a wooden door stopper and whipped it at his head with all his strength. The man stumbled back and grunted in pain before Beastboy tackled him to the ground. Robin sprinted over and kicked the gun away from his hand.
     Beastboy gripped onto him as they stood up. "Don't try to run bro, we've got you now." Beastboy grinned as he grabbed the back of the man's head and shoved it against his armpit.
     "Hey what the fuck! Aaaah fucking disgusting! Let go of me!" Beastboy giggled and then looked over at Robin. 
     "What do you say we take this guy over in the alley and teach him a lesson?" Robin bit his lip and nodded. Beastboy followed Robin out of the store, keeping his new friend smushed against his nasty pit as he went. The cashier was too stunned to speak.
     They walked down a secluded alleyway not far from the store. Beastboy shoved the robber at a brick wall, where he slouched to the ground with his back against it. The man stared nervously at the bulge in Beastboy's pants, who had a full on boner.
     Beastboy started unbuttoning his pants. "Hey Robin, those sodas we had early sure are catching up to me." Robin smirked as he reached for his pant buckle.
     "Yeah bro, same." Beastboy whipped out his erect cock and quickly started powerfully spraying piss onto the robber. The gush of warm golden liquid splattered across his chest and stomach and cascaded down to his lap. Robin joined soon after, pissing right on his hair and face. Beastboy moaned.
     "Fuuuuck yeah. Bet it feels great to get drenched in our nasty piss, huh?" The robber squirmed and whined in protest, but ultimately he knew he couldn't do anything to stop it.
     After a couple minutes their streams died down. The man's clothes were completely soaked and a large yellow puddle had formed under him. Beastboy sighed with relief. "Fuck that felt good." He took a couple steps closer to him and shook the last drops of piss against him, his dick slapping against his face. "Ready for some more fun?" Beastboy looked around the alley, they had about ten feet of open space behind them. "Get up and lay down right there. On your back."
     The man reluctantly got up from the ground and went over to where he was told. Once he was laid down Beastboy crouched above his head and brought his ass down on his face. The seat of his uniform was moist with sweat and his ass reeked like crazy. The man let out a muffled cry as his face was smothered in the stench.
     "Haha, sorry bro, I've got major swamp ass." Beastboy's stomach gurgled loudly.
     "Aah fuck, you're about to get hit with so much gas dude." A ten second fart rumbled out against his face, the intense smell engulfed his nostrils immediately. Beastboy grinded his butt back and forth as he ripped a few smaller farts. "Fuck yeah, how's it smell, you like that shit bro?" Beastboy's dick, still sticking out of his uniform, began dripping precum on the robber's torso as he continued to rip ass on his face. Robin stood a few feet away jerking off at the incredible sight.
     Several minutes of grotesque face farting passed, and each fart was getting more and more wet sounding. "Here comes a big one." He grunted and blasted a loud sloppy shart into his pants. The robber groaned in agony as the stench was much more intense and smelled like straight up shit. "God, I'm gonna explode in these fucking pants. Hope you aren't too squeamish bro." After two more nasty sharts a wave of warm soft poop began to fill the seat of his pants with a loud SPPPLOOOOORRRTCH.
     "Aah fuck! It's coming out dude." He continued to grind and smush the load onto the man's face as more shit and farts bubbled out of his ass. Without even touching it, Beastboy's dick began shooting ropes of cum onto the lower half of the man's body.
     Robin began jerking faster. "Holy fuck, that's so hot." He stepped over to the robber and sprayed his jeans with cum. Beastboy looked down at the man under him, who was currently trying not to gag. "Thanks for the fun bro. Maybe next time you'll think twice about robbing a store, huh?" The man responded with a muffled groan. The two heros laughed. "Alright Robin, let's turn this guy in to the cops and then get back to the Tower, I'm exhausted".
