"I'll fart on your dick to make it warm!" Luna said excitedly, turning around to present her bare perfect arse. Her cheeks were as soft as ever, Neville whimpered as his soft cock was placed between her cheeks. It certainly was warm. Nevilles dick immediately began to harden at the cushion effect. "Here come my smelly farts." she said with a giggle, and just as her sentence finished, a soft but loud fart left her shit hole and blew onto the waiting cock. Neville groaned in delight as he cock grew even harder. "If your cock gets any harder it'll block my hole!" she giggled again, letting out three big farts in a row. The boy apologised with a frail voice, his eyes locked on her perfect arse, his cock in heaven.
Luna's cute farts continued, but Neville needed more friction, and he desperately needed to cum. His right hand grabbed his large cock and slowly he rubbed it over her fart hole and on the cheeks, Luna had no issue with this as it felt great for her, especially when his cock head pushed against the shitter when she farts. "My arsehole really stinks, doesn't it?" she asked casually. Neville, whose eyes were rolling back due to pleasure, could barely nod in agreement. Luna continued to fart and Nevilles wanking increased in speed. Luna stepped away slightly, her arse still directed at his cock, and used both hands to hold her arse cheeks open as wide as possible, stretching the delicious little hole. "I'm running out of farts!" she said with a strained voice and a wicked grin. "Imagine if Ginny were here too, farting all over you. I've tasted her shit and I must say she produces a rather delicious taste and smell." She said the weird sentence so calmly but also sexily, and that pushed Neville to breaking point.
"I'm gonna cum over your smelly arsehole, Luna!" Neville began to panic as his orgasm built up, it was his most powerful yet. Wanking himself with great speed, with a triumphant groan and one final big fart from Luna, Nevilles cock exploded with rope after rope of warm cum, splattering Luna's arsecheeks and covering her dirty anus. Luna moaned in delight, the relief of all that farting was refreshing, and she loved being cummed on. Neville was panting, wanking every last drop out onto the waiting arsehole. "Wank into my arsehole!" she ordered, and, still cumming, Neville pushed the head into the used hole and finished out his best ever orgasm inside the filthy anus. "My disgusting farts made you cum, and you came right up into my shit!" Luna was rather proud of herself, Neville, embarrassed, let his cock slip out with a sigh. Luna turned around and placed herself on his knees, her little wet cunt dripping.
"Did you have a good wank?" She asked, placing a kiss softly on his shaky lips. "Y-yes, thank you." he whispered in reply, his eyes closed. "My b-best ever." he stated, Luna smiled. "I'm sure it'll be much better when we have the girls involved. Imagine us all farting and shitting together!" as she spoke, Nevilles cock grew hard again. "Hermione and Ginny are such naughty whores for shit, it's funny how quickly they changed from being utterly disgusted by it to becoming obsessed with it." Luna explained calmly, her fingertips running up and down Neville's cock, which was erect again. "And I would rather like to introduce them to animal sex. Cats make me cum all the time, you see. Hermione would take some persuasion, but knowing Ginny the little shit slut, I think she'd be game from the start. Would you like to see little Ginny Weasley squirting her cum all over a cat?" she asked, and Nevilles reply said it all. With a groan, he emptied what little cum he had left over Luna's hand.
"Well then, fart boy. Let's go get her."
