"Myrtle, are you in here?" Luna's gentle voice cut through the silence of the empty bathroom. A pipe banged, followed by a grunt, in response. Luna's lips curled into a grin, and she removed her robe walking in the direction of one of the stalls. She sat on the toilet and lowered her skirt, revealing her pussy which glistened with piss and saliva. "Myrtle, look…" her voice was not much more than a whimper. Another pipe banged, this time much closer, then through the wooden side of the stall came a head.
The ghost had glasses and freckles, and looked very young. Myrtle's eyes gazed from Luna's down to her exposed pussy. She licked her lips. "Are you going to cum for me again, Luna?" she said, with the familiar agression in her voce. She gave Luna a look she might have given Harry, and started humming to herself, tracing Luna's hand down her chest to between her legs. "Oh yes Myrtle, I've cum so much today! But I always have some left for you." She finished with a giggle, which then turned into a moan as her fingers found her clit.
Myrtle entered the stall fully, and hovered in front of Luna. "You're such a little slut, Lovegood. Everybody knows it." She said spitefully, enjoying the view. Luna whimpered with pleasure and knew she wouldn't last long. Her index finger gave her clit a flick, sending a shiver up her spine. "You know I like it when you call me that, Myrtle." The blonde said with a grin, her moon-like eyes gazing through the ghost before her. "You wouldn't believe the things I've been up to this week.." her voice was broken by a whimper, Myrtle had lowered her robe. Luna's whimper turned into a groan as she pinched her clit hard, forcing juice to leak from her hole.
"I want to see your little asshole, Luna. Show me it." Myrtle said, again with that familiar agression. The ghost knew the little whore would do anything she told her to do. Luna's response was a smile, before quickly turning around and bending down, her small hands on the edge of the toilet seat, her bare ass and pussy on display. Luna's asshole was simply delicious. "Such a pretty little shit hole." Myrtle commented as she floated closer to the girl, placing her piercingly cold ghost hands on Luna's hips. "I want to see you shit, Luna." The demand was simple. Luna's eyes lit up in shock. She had never shit for anyone before, but suddenly she felt the desire too.
"You heard me, pretty little slut. I want to see how pretty your shit is." Myrtle let out a mad cackle then licked her lips. Luna's smooth facial skin developed a blush, and as she closed her eyes, she pushed with all her force, grunting and moaning as she forced herself to shit. "I-It's not coming out.." she said, exhaustedly. Her little shitter was opening and closing, inviting Myrtle in. "Perhaps this'll help…" The ghost balled her hand into a fist and pushed it into Luna's open asshole. It was ice cold, making Luna bolt upright with a scream. "No! No, it's so cold in my ass. Please, please wait for my shit to come." She begged, not being able to handle the torture of her cold pale hands.
"I haven't got all day, bitch! I need your shit now!" she yelled as Luna lowered herself back into position, trying to empty her bowels. "I think i-it's coming" she said with a moan. Luna couldn't believe it. She had forced herself to shit, and it felt fantastic. "Oh fuck, oh, oh fuck, I'm gonna shit, it's coming out, I can feel it!" her voice was full of excitement and pleasure. Myrtle had a look of pure arousal as she watched Luna's tiny asshole open up, producing a light brown shit. "I can see it! Shit for me, empty your bowels!" The ghost demanded, rubbing herself all over as the huge shit came out. Luna had reached between her legs and started frantically rubbing her dripping pussy.
"I'm gonna c-cum, I'm gonna cum whilst shitting, oh gosh, oh fuck, my shit is making me cummmmm" her sentence turned into a scream, as feaces poured out of her asshole, liquid began squirting out of her pussy. "Cum you filthy little bitch! Look at you, being forced to shit and getting off on it!" Luna's shit continued to flow out, running down her legs and splattering on the bathroom tile. Myrtle moved down close to inspect it, inhaling the smell. Luna's legs began to shake, shitting whilst cumming had made her feel so good she felt like she was going to pass out.
Breathing heavily, the blonde turned around and sat down, her legs open with the pile of her shit between them. Myrtle looked the happiest anybody had ever seen her, Luna however, exhausted. "So much shit came out my bowels!" she said, taking a breath before every other word. She was proud of herself, and despite cumming hard, she was still as horny as ever, watching Myrtle admire her mess. "I didn't know you had a thing for shit, Myrtle. So disgustingly naughty." She said, and added a chuckle, dipping her finger into her soft warm shit. Myrtle darted a glare at the blonde girl. "Lick it off your finger."
"You know what, Myrtle. I think I'll eat it all."
