Kelly watched in excitement, as her massive husband effortlessly lifted the drugged hero and dropped him onto the couch. Batman continued trying to move, but it was no use. Kelly hovered over his stomach momentarily, then dropped her huge ass down, knocking the wind out of him. He barely had time to get his breath back, before the even larger ass of Brian slammed roughly onto his head. Unfortunately for him, his face wound up under the massive crack. Even through his pants and underwear, Batman could smell a nasty stench within the crack.
"Wow, I can't believe we're actually sitting on the Batman," Kelly said, bouncing up and down on his stomach.
"That's nothing babe, watch this!" Brian said with a smirk.
A second later, Brian released an absolutely thunderous fart, shaking the couch.
*FFFFAAAAAAAAAAAAAAAARRRRRRRRRRRTTTTTT*
Batman first felt the hot air buffet against his face, then came the smell. It had to be the worst stench he had ever experienced. It burned his nose, and stung at his eyes. Even a hero like himself couldn't help but gag, the stench rocking even his hardened senses. Even Kelly had to cover her nose, and move away from the couch, trying to escape the smell.
"Holy shit Brian, that smells terrible!" Kelly yelled, trying to fan away the smell. "You could have warned me first!"
"That was just the start babe," Brian laughed. "Oh, here comes the real deal!"
*PPPPPPPPFFFFFFFFFTTTTTT*
*FFFFFFFAAAAAAAARRRRRRRRRRTTTTTT*
*HIIIIISSSSSSSSS*
*BBBBBRRRRRRRTTTTTTTTT*
Fart after massive fart exploded out of Brian's ass. Each one seemingly worse than the last, somehow. Kelly was stunned at the amount of gas her husband was releasing. Despite the terrible smell however, she felt herself getting turned thinking of him torturing Batman with his ass. Meanwhile, under the massive ass, Batman was in absolute hell. He regretted ever stopping to check on the couple, putting him in this awful situation. Brian continued his barrage for several minutes, before he suddenly stopped. There was a loud rumble heard from Brian's gut, then he clenched up.
"Oh shit, here comes the big one!" Brian shouted. "Hope you're ready for this Bats, it's gonna be bad!"
*FFFFFFFFFFFFFFFAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRTTTTTTTTTTTTTTT*
He wasn't wrong, it was the biggest and worst yet. It was so massive, Kelly was sure she felt the floors vibrate beneath her. The smell was even worse, unbelievably so. It had spread almost instantly through the room, sending Kelly into a coughing fit. Batman thought he was in hell before, but that was a walk in the park, compared to this. The previous barrage didn't even compare to this monstrous bomb. He actually felt as if the stench was suffocating him. He honestly thought, that this stink might be the last thing he was ever going to smell. Ten mind-melting minutes later, not even Batman could continue to endure, and he passed out under the massive stinking ass.
