2103 Yuko story (Pixiv Fanbox)

"Heyyy~ come here part-timer…" Yuko called out, Watanuki entered the room waiting to be abused by Yuko again. "What is it Yuko-san? More Sake? I just filled your glass-". "No, I need you to participate in a little experiment for me." Yuko interrupted. "Experiment? What are you up to this time?" Watanuki said sceptically, Yuko smiled and waved her hand for him to approach her; "Come here~". Yuko was on her side with her arms cradling her breasts, her Kimono revealing a sizable amount of bare skin. As he came closer, she shifted her right leg and revealed her backside. She was wearing a pair of black panties that covered a medium amount of cheek, Watanuki couldn't help but notice but was quickly distracted by the fact that he couldn't move. Black smoke was emanating from Yuko and had a hold of his body, it started to move him behind her so that his face was approaching her buttocks. "Y-Yuko-san, w-what's happening…" Watanuki struggled, Yuko put a hand on her butt and spread it open as she spoke; "Don't struggle little boy, I just want you to enjoy my gas~ huhuh~ Tell me what it smells like~". As she finished speaking his face met her derriere, his nose pressed all the way into her crack and his eyes completely blocked by the fatty cheeks she held open for him. After a moment, Yuko could be heard making a small moaning sound followed by the hiss of a steamy fart exiting her anus. The stink filled Watanuki's nostrils and dominated his thinking, "It s-smells like...s-sake and eg-gs" he exclaimed as he breathed in her pure fart. Yuko giggled and slowly wiggled her butt in his face to tease him, "huhu, this is even more amusing than i'd predicted~ ...It feels good letting loose on your poor helpless nose! Maybe next time I'll have you lick it for me~" As she reveled in her amusement, she let out another burst of potent smelling gas. Watanuki gagged, the stench was vile and far from womanly. Even Yuko could tell how smelly it was, she plugged her nose and fanned it away from herself; "Ooh~ That stinks! It must smell so much worse from where you're smelling it~" she said, farting again. Then again. Yuko looked down on him and savored having him sniff it all up, "Now let's see if you can taste that sake too~" she said sadistically, pushing her butt into his lower face. His mouth was completely sealed and her butthole was in prime position to fill up his throat. "Enjoy your meal~ and don't blame me for any bad breath, you're the one who makes my meals for me boy~" She teased as she pushed out a loud, wet and flavorful fart into his mouth. Watanuki shook as he swallowed his master's thick gas, Yuko could only smile and watch his body quiver and struggle for air. "My~ You managed to move even while under my control, did it taste that bad?~ Huhu…" She rubbed her butt up and down his face until she settled back in her original position. "Mmh~ This just has to be my favourite spot~" She said as her soft buttcheeks rested on his eye sockets again. She then continued farting until she would eventually fall asleep, still sat atop his face...
