“Why don’t you lie down on my bed and make yourself comfortable,” Robin suggested as he eyed the mountain of green fat standing in his room. It would be a problem scaling the towering fattie, but once she lied down, he could pounce. He watched her jiggle towards her bed, following the bob of her meaty ass with every lumbering step. She didn’t so much sit down on the bed, but throw herself on, landing belly first on the well used mattress. Robin winced when he heard something crack inside his bed.

“Oops, sorry about that. You earthlings have such puny bed.” Robin nodded dumbly. He had Cyborg reinforce his bed to be able to hold a dozen women for his wilder nights. The loss of his bed didn’t bother Robin, but rather propel him forward. He had this mountain of jiggly flesh waiting for him and he was thinking about his bed. Pulling his shirt on, he crawled between Megan’s thick, spread legs, completely naked, strait towards the giant green blobs that beckoned him.

“Going to fuck some real ass tonight,” Robin whispered as he got up to Megan’s ass on his knees. Her backside sat all the way to his chin, blemish free and so wide that it went over the side of the bed. Leaning forward, he didn’t just burry his hands in the glutinous masses, but also pushed his cock into her dark, narrow ass crack. He kneaded handfuls of ass fat with both hands, rubbing his cock into the plush, dank crack as he massaged the cheeks. Not only did her cheeks feel great around his cock, but the cushy fat of her ass felt amazing as it moved over his fingers.

Robin had never grabbed anything so soft and squeezable. It made Power Girl’s breasts seem tough by comparison. The smooth fat practically absorbed his hands making his cock throbbed in excitement within the crevice of her ass. Grabbing and squeezing it, grinding it against his body, Robin reached to the sides and pushed the buns harder around his cock, a loud groan escaping him as he felt the pliable masses embracing his meat.

“Your ass is incredible!” Robin groaned as he leaned his head down and rubbed his face on the top of the ass cheek. His mouth opened and he sucked a mouthful of Martian booty into her maw, sucking on it wetly as he humped and grinded the ass meat. Megan giggled at his antics, not enjoying it as much as Robin, but finding that his antics were well worth it.

“You humans have such a fixation on what’s on the outside, don’t you know the best stuff is on the UUUUUURRRRRPPPPP!”

Whatever Miss Martian meant was interrupted as she let out a huge burp. It lasted a few seconds, but her body jerked through the whole thing, making her ass cheeks jiggle like crazy. Robin moaned loudly, hugging the ass cheeks even harder. His cock felt like it could melt inside these yielding buns and he imagined painting them white when he came. He ran his tongue over the top of the cheek, groaning, as he got lost in a wave of hormones.

“Seems like changing my body so much built up some gasses. Robin, maybe you should move away from me until I empty out all the excesses gas?” Her suggestion went ignored as Robin kept humping her ass. He didn’t care if she burped while he was on her ass. Hell, he liked how burping made her jiggle. He kept manhandling her ass cheeks even when he heard a loud gurgle from deep inside Miss Martian. As her belly started to rumble, Megan uncomfortably said, “Too late.”

“PPPPPPPHHHHOOOOOOOOOPPPPPPPP!!!”

A massive gust of wind blew out of Megan’s ass hitting Robin in the stomach. It reminded the boy of being hit by Bane, only the punch left a terrible smell. He tried to hold on as the gale winds blew from Megan’s rump. His fingers gripped her ass cheeks desperately as the fart continued to push him back, but the softness that he adored made it impossible to hold on and he went flying ten feet back right into the wall. Slumping down to the ground, his cock still twitching, he stared up as Megan’s ass continued to release excess gas. Yellow smog filled the room, wafting around on the floor. Not wanting to be caught in the stinky fog, Robin moved quickly back to higher ground, retaking his spot on Megan’s ass.

“Sorry about that,” Miss Martian softly said, burying her face in the mattress as another small toot escaped her ass. Robin didn’t say anything, he just breathed slowly, getting used to the thick, murky air in his room. Trusting himself to speak, he smiled pervertedly. “Don’t worry about it, I’ll just plug up the hole so you don’t fart again.”

Robin made it sound so innocent, but Megan knew what he was planning to use as a cork. Her lime green face turned a darker green as Robin dug his hands into the crevice of her ass and pulled the blobs apart. He stared at her dark green, puckered asshole, the source of the gas and the means of his orgasm. Gripping his cock in his hand, he crawled in between her cheeks, his body disappearing between the hunks of jiggily meat. Rubbing the shiny head of his cock against her ass hole, Robin prepared to push in.
