While Gwen had been experiencing her first orgasm, Ben was being gradually pulled deeper between Gwen’s boulder like butt cheeks. Her jiggling ass flesh smothered him, trying to fill the space Ben was currently taking up between the massive cheeks. Her hot, fat flesh was everywhere, pushing against his face, rubbing up his arms and when he opened his mouth to breath, he even tasted Gwen’s fatty ass. All the wiggling Gwen was doing caused her ass halves to slowly envelope Ben further, sending him face first to the end of the line. With the little amount of light streaming in, Ben could clearly see a tiny, puckered hole that he knew had to be his cousin’s asshole.

The sight of Gwen’s rosebud almost made Ben gag, but he stopped himself at the last second by remembering that if he opened his mouth to retch, it would fill with ass. Ben stared directly at the tiny, wrinkled opening, unable to move his head with all the ass surrounding him. The fat around Ben rumbles ominously as the doughy walls jiggle from the raspy breaths Gwen was taking.

Gwen was coming down from her first orgasm, but her libido had not been fully sated. She looked down at her messy slit, hanging right above her huge ass and Ben’s franticly kicking feet. She had never felt so alive until she experienced the sensation of Ben squirming around under her. The more of her ass that touched the boy, the more excited she became. She wanted more of this wonderful sensation, no matter if the friction of her cousin’s body against her massive booty caused it. Smiling wantonly, she started to violently wiggle on top of her trapped cousin, pushing him face first into her quivering asshole. The moment Ben’s face touched Gwen’s anus two things happened. Pleasure shot through Gwen’s body at the sensation of having her hypersensitive anus touched by a foreign object and a gas bubble in her rectum was released.

The last wiggle from Gwen shoved Ben’s face directly into her anus, pressing the creased pucker directly against his face. Ben’s eyes shot open in horror at the slimy touch of Gwen’s aroused anus. He watched as he sticky lips slowly breathed out and peeled open before Ben’s face. The gas came out in a single burst, filling Ben’s lungs with its foul odor. Ben loved farts, his childish nature made releasing gas to seem like the funniest thing. He used to love ripping the foulest fats, especially when there was someone around. Flatulence was his favorite weapon against one person though, his cousin Gwen. Whenever he wanted to be alone, he’d just concentrate and let out a ripe one that would empty the room. He had thought the sight of people grimacing at the smell was the funniest thing. Well, he was no longer going to think that after this.

“Oops,” Gwen giggled and blushed after farting. She’d barely noticed it with all the pleasure coursing through her. She looked down at Ben’s legs, they had stopped kicking and were just twitching on the ground. Her grin grew insanely wide at the thought of what Ben must have been going through between her ass cheeks. Revenge was so sweet for her, but very foul for Ben.

Underneath her, Ben’s eyes were watering as the smell lingered under Gwen. With her cheeks firmly planted on the ground, the noxious fumes had nowhere to go and were wafting around Ben as the only source of air. He breathed Gwen’s entire fart in through his nose, unable to breath through his mouth or taste the rank ass around him. The smell filled his body, making him feel dizzy and nasty all over. It could have been the foulness of the smell, but Ben was starting to feel funny.
