After cleaning herself up again, Luna noticed it was time for her next lesson. She removed a glass container from her bag and again, in full view of Myrtle, she held the container below her pussy and filled it with piss. Her flow came to a stop and she raised the glass to her lips and took a tiny sip. Her nose crinkled and she giggled, then placed the container back in her bag and skipped off humming to herself towards the dungeons.
Her skipping soon came to a halt when she noticed Mrs Norris, her tail tapping the stone floor in an empty corridor. Luna had a wicked idea. She removed the container that she had just filled with piss, and poured a spot on to the ground before her. Mrs Norris came curiously towards the damp spot and smelt around it. "Tasty piss for the kitty cat." Luna whispered, holding the container steady in her hand. The cat began licking rapidly at the floor and Luna felt her clit tingle.
"Mmm, you like my piss don't ya!" she said with a giggle, and poured more of the warm liquid into her hand, feeding it to the thirsty cat. She giggled some more, then moved around the corner, concealed from view. She lowered her skirt and exposed her hairless pussy, Mrs Norris licked her lips and sat close to her. Luna knelt down onto the stone floor and poured some of her piss onto her hand, then rubbed her pussy with it, moaning softly at how good it felt. "Lick it all up kitty." She whispered seductively, then moaned aloud as she felt Mrs Norris's wet tongue lap at her pussy.
"Mmmm, having my pussy licked feels fantastic! A thirsty pussy for my pussy!" Luna giggled again and poured more piss onto her clit. She reached round with her other hand and rubbed some piss onto her extremely tight anus, and Mrs Norris moved under her legs, her rough fur sliding right across Luna's vagina, and began to tongue her shit hole. The sensation of the tiny cat tongue was incredible, and Luna moaned incoherently as the cat licked and licked and licked.
The blonde reached down to stroke the cat, playing with it's tail and rubbing it's legs, then stopped to drench her anus in more of her piss, then moved her hands to her soaked pussy and began frantically tapping at her clit, eager to cum whilst the cat licked her ass. "Keep licking that dirty hole kitty, you're gonna have me cumming so soon! Oh Merlin I am naughty." Her breathing was heavy and her legs felt weak, she couldn't take much more and emptied the rest of the container over her bum, feeling drops leak down between her cheeks, and Mrs Norris tiny tongue was there to meet them.
"FUCK, HERE IT COMES! I'M GONNA CUM! A CAT IS MAKING ME CUM!" she was almost screaming at her third orgasm of the day, and after frantically slapping her clit, she squirted cum onto the floor in front of her, her legs shaking before finally collapasing just as the cat had moved out of the way. Mrs Norris mewed at the girl who gave her one last stroke, and she leaped up onto the ledge above and disappeared from sight, leaving the blonde to recover from her first animal expiriance.
Some moments passed before she recovered herself, but soon she was back on her feet and strolling around the corridors as if nothing out of the ordinary had happened. She had missed the first half of her potions lesson and decided not to go, instead she took a stroll around the castle, eyeing up anything she thought could give her pussy pleasure.
