"Come on Button, you can do it," Rumble cheered.
"Ok, here I go," Button Mash said as he opened his mouth as wide as he could and shoved the orange in. He'd always been able to swallow things in one bite most ponies couldn't, but Rumble's dare was the biggest yet. Slowly he felt the fruit slide down his throat and into his stomach. "Done! You owe me five bits," he smiled.
Rumble huffed as he hoofed over the coins. "Just you wait, I'll find something too big even for your big mouth."
"I doubt it," Button smirked. "I bet I could even swallow your head."
Rumble laughed. "Yeah right, I'd give twenty bits if that were possible."
"Let's do it then," Button said
"Seriously?" Rumble asked in disbelief. Button just stared at him. "Hey, if you wanna lose the bits," Rumble said, still giggling.
Button stood over Rumble and opened his mouth wide. His lips swapped around Rumble's forehead, but he couldn't open any wider. He pushed with all his might but all that happened was Rumble fell to his belly. "Looks like you owe ME twenty bits," he sad.
Button kept pushing, his mind filled with thoughts of what it could feel like to have Rumble's head in his mouth, struggling as he tried desperately to escape. As he imagined a strong tingle rushed up his back and into his head. Slowly he felt his jaws widen until Rumble's head slipped inside. A tide of pleasure raced down his spine. He was doing it! He'd actually fit the colt's head into his mouth.
"You actually did it," Rumble mumbled, his voice muffled by Button's cheeks. "Now let me out."
Button was lost in the sensations of swallowing Rumble's head. His tongue licked all over the colt's face, every inch pleasuring his taste buds. Without thinking he gulped, and his friend's neck vanished inside his jaws. Everything faded away except for the feeling of Rumble in his mouth. He quickly gulped down the pegasus's chest and stomach. Next came his crotch, and Button moaned at the tastes there. He licked all over Rumble's balls, his sheath and even his tailhole. He felt Rumble's cock emerge and he attacked it with his tongue, licking and sucking until he tasted a sweet but salty liquid fill his mouth. Another strong swallow sent the last of his friend down into his stomach.
Slowly Button came down from his pleasure high and looked down at his massive stomach, swollen with the body of another pony. "Wow, I actually ate him! Wait, I ate him! Friends aren't food?" As his mind raced, Button...
