Luka was out shopping, buying herself clothes and jewelry, when she spotted a necklace that caught her eye. The chain was made of pure gold and it had a yellow, heart shaped diamond no smaller than her thumb.

"OOOOH! It's so beautiful." Luka said to herself. She looked at the price tag and saw that it costs 15 million yen. "NANI?! Who could afford this?"

Luke then heard what sounded a picture being taken from below her. She immediately turned around and saw a man fast walking away from her.

"HEY!" Luka yells.

The man started running out of the store and Luka followed suit. She continued chasing him down until she finally caught up with in an alleyway and tackled him to the ground.

"Get off of me." the man demanded.

"Urusai baka." Luke replied before getting up and putting her foot on the man's chest. She picked up his phone off the ground and looked at his photo gallery where she saw dozens of pictures of women's upskirts with a picture of her's being the most recent one. "You disgusting pervert."

A thought came to Luka's mind and she devilishly smiled. "You like seeing up girls' skirts? Then have a very close look up mine." She straddled the man's chest reverse cowgirl style before lowering her hips until she was sitting right on his face. "Enjoy." She gyrated her hips tauntingly, rubbing her ass in his face.

The man tried pushing Luka off of him but she responded by punching him in the balls, causing him to wince and hold his crotch in pain. "I didn't say you could touch."

Luka's insides started making gurgling noises and she held her stomach in discomfort. "Ugh, why did I have to have that second bowl of Doc's natto? It tastes so good but it gives me the worst gas."

PPPPPPFFFFFFFFFFFRRRRRRRRRRRRTTTTTTTTTTTTTTTPPPPPPPPPPPPPPPPPPPPPPPPPP!

Luka let out a fart that sounded like a trumpet was being played. "Oh, that was so relieving."

The man started convulsing and flailing, he had never smelt something so horrific.

This gave Luka an idea for further punishment. "What's the matter? Can't stand the smell?"

FFFFFFFFFFFFFFFFFFFFPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPFFFFFFFFFFFFFFFFFFFFFFFFFFF!

Luka let out yet another trumpet sounding fart into the man's face. "I'm starting to enjoy this." She started bouncing up and down like an excited school girl.

The man, on the other, was in anguish. Not only was his face being smothered by a girl's ass, but she was ripping farts that smelt worse than what he thought possible.

FFFFFFFFFFFFFFFFFFRRRRRRRRRRRRRRRRRRRRRRRRFFFFFFFFFFFFFFFFFFFFFFFFFFFFFPPPPPPPPPPPPPPPPPPPPPPPP!

BBBBBBBBBBBBBBBBBRRRRRRRRRRRRRRRRRRRRTTTTTTTTTTTTTTTTTTTTTTTTRRRRRRRRRRRRRRRRRFFFFFFFFFFFFFFFFFFFFFFFF!

PPPPPPPPPPPPPPPPPPPPPRRRRRRRRRRRRRRRRRRRRRRRRTTTTTTTTTTTTTTTTTTTTT
PPPPPPPPPPPPPPPPPPPPPPPFFFFFFFFFFFFFFFFFFFFFFFFFFFFRRRRRRRRRRRRRRRR
RRRRRRRRRRRRRPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP!

Luka released 3 more farts, each one longer and smellier than the last. She excitedly rubbed her ass up and down across the man's face, she was having the time of her life. "Who knew passing gas could become so much fun?"

The man started crying into Luka's ass, he wanted this all to end.

Luka spent the next 30 minutes letting out fart after fart into the man's face, after which she was finally empty. "Oh, that all felt so good to let out." She stoop up off of him and reached into his pockets and pulled out his wallet.

The man would've tried to stop her, but spending half an hour with his face in her ass and smelling her farts made him too weak to do so. He could only watch in despair as she took out his credit card and tauntingly hold it out in front of him.

"Thanks for the diamond necklace." Luka said before she threw his wallet back at him and walked off.
