Luna and Cho sat on a bench in the Owlery, holding hands. In front of them they watched Ginny Weasley being screwed up the arse by a First Year boy half her size. This often happened, as the boys in the school knew. Ginny would let anyone fuck her as she had become so obsessed with anal, she needed it every day, and it was fun taking boys virginities. "I don't think there's a First Year that hasn't taken Ginny's arsehole." Luna said quietly as they watched. "I can't believe it!" Cho said with genuine surprise. "So naughty and slutty." Luna said, and they both giggled. Ginny looked over and winked, then her face contoured into pain as the First Year boy spanked her. She looked over her shoulder at him and called him a bastard, grinning. The boy then started to whine. "Cumming, Ginny!" he announced with a strained voice. "Cum inside my arsehole like a good boy." Ginny said calmly, the two then started to moan loudly at the sensations.
The boy slipped his small cock out, wanked the last drops of cum into Ginny's arsecrack, gave her a quick kiss then left, winking at Luna and Cho on his way out. Cho looked away but Luna smiled dreamily making the boy hard all over again. As the boy vanished down the stairs, Ginny came over to the two. "Clean us up, babe?" she asked with a smirk. "Of course." Luna said, watching Ginny turn so her arse was facing her. Luna got on her knees. "Spread your lovely cheeks for me, please." she asked kindly, and Ginny did, exposing her cum drenched arsehole to Luna. "Such a messy stinker." Luna commented, making Ginny blush. "Have a good look, chink." Ginny said to Cho, when she noticed the Asian was looking with raised eyebrows. She flushed, but continued to watch. "Fart!" Luna said, opening her mouth. Ginny let out a sigh, then a groan as she pushed her bowels outwards, farting cum into Luna's mouth.
She swallowed, then wiped Ginny's arsecrack with her hands, getting all the cum off. Ginny turned around and Luna and Ginny began to lick the cum off her hand, like little kittens licking at an ice lolly. Cho's pussy was utterly soaked at this point. "A-are you here every day, Ginny?" she asked with a nervous voice. "Obviously." Ginny begun. "I need a good seeing too every day, it's healthy." she said, her eyes closed. "Does Harry... know?" she asked. Ginny opened her eyes and gave Cho a blank stare. "Oh, Cho. Harry is just the same. He and Ron are probably giving it to some twelve year old now." Luna said dreamily as she finished cleaning the cum. Cho looked a little sad, but she admitted that she wasn't surprised. She wanted Harry all for herself, but that was never going to happen. "Those boys prefer younger girls, and I'm a bit bored of Harry anyway, that's why I come up here and wait for whoever shows up." Ginny said without shame.
"Anyway, my love, we must be off." Luna said, rising. Ginny started to dress herself, and snogged Luna goodbye. Cho gave her a weak smile and Ginny winked at her, purposely keeping her breasts on display. "See you around." Ginny spoke, and the two girls left and walked back to the castle, Luna leading Cho to Myrtle's bathroom. "My bowels are all full up, come with me to empty them." Luna said casually, and dragged Cho into the bathroom by her hands. "Luna! You know which bathroom this is!" she said nervously, looking around. Luna nodded and walked to a clear space and squatted, moving her robes out the way to show off her smooth legs and bum. "Luna!" Cho said with wide eyes, watching as the small blonde girl produced four large lumps of shit directly onto the floor. "Mmm, there we go." Luna said, happy. She stood up and her robes fell back down.
"I know that smell anywhere." said a shrill voice, making Cho jump. Luna smiled as she watched Moaning Myrtle float down from the ceiling, floating in front of Luna's mess. "Don't tell me you're going to waste all that?" the ghost asked, darting her eyes between Luna and Cho. Cho was completely stunned, but excited. "Oh, no, of course not." Luna spoke, removing her robes in quick movements. Within seconds she was nude in front of Cho and the Ghost. Luna walked closer to Myrtle, with the pile of shit between them both. "Go on then!" Myrtle spat, and Cho watched in amazement as Luna began wiping her shit all over her body as if she was in the shower and it was soap.
"Shit is great for your skin. How do you think I stay so smooth and pale?" Luna said, guiding Cho's hands to her chest after walking back over to her. Cho was electrified at the touch, her fingertips exploring her flat shit covered chest and nipples, which started to peak to attention. "Pull and twist them please." Luna spoke with her eyes closed. Cho hesitated, still embarrassed under the watchful eye of the Ghost. Myrtle hovered down beside Cho and gestured for her to do it. The Asian rubbed her thumbs over Luna's growing nipples, pressed down on them making Luna let out a little groan. "Please, Cho. Wank my nipples!" Luna pleaded, pushing her flat chest outwards. Cho, with a nipple in each hand, pulled outwards, amazed at how far out they could stretch. Myrtle chuckled as she watched.
"Yessss! My nipples are yours to do as you wish!" Luna said, entering one of her sexual frenzies which Myrtle had seen before. "Wank the sluts shitty nipples!" Myrtle spat, floating around the other side to get a better view. Luna was moaning softly as Cho began rubbing the nipples back and forth, soft at first then getting rougher. The more Cho pulled them, the more it looked like Luna had tits, and the more the shit would run down her body. Cho was now aware how big her own really were. Cho suddenly twisted one nipple to the right, making Luna squeal. Myrtle chuckled again and started to run her Ghostly hands all over her own body. Cho then twisted the other nipple to the left and pulled outwards with them both even more, this time Luna's scream could be heard halfway down the corridor.
Luna collapsed onto her knees from the pressure, but Cho kept her grip and started rubbing them, the two girls now both on the floor. "Oh, it's so wonderful!" Luna moaned, gazing up at Myrtle. Myrtle stared back down at her, then removed her robes, exposing her translucent chest. Cho stared up with curiosity, taking in Myrtles average sized breasts and licked her lips. "Quit staring!" Myrtle spat as she moved down to join them, hovering just slightly above. "Get yours off, chink." Myrtle demanded, but Luna let out a little whimper as that meant Cho had to let go of her nipples. But in Myrtle's bathroom, you did as Myrtle said, and Cho with trembling hands removed her robes, exposing her creamy large breasts. "Mmm!" Myrtle moaned, running a Ghost hand across the breasts. The chill gave the Asian instant nipple erections and she shuddered.
Luna never missed a thing, and seeing Cho nipples at full attention she pounced on the girl, her shit covered body rubbing against Cho. "You're getting my shit all over me, Luna!" Cho tried to shuffle away but Luna had her pinned. "You should have seen the state of Ginny." Myrtle said, who was now massaging her own breasts, squeezing them together and twerking her nipples. Cho was red with embarrassment, but the moment Luna had her nipples in a grip she forgot all about it. A tingle went up the Asian girls spine as Luna pulled her nipples outwards. "Oh fuck, what a feeling!" she cried out as Luna twisted them slightly. "Umbridge taught me this." Luna said softly, and before Cho could even ask, she was squealing because Luna had clamped her nipples down with all the strength in her fingers. "Luna!" she cried out. "It feels like I'm gonna cum, oh god!" she was wriggling like crazy as Myrtle cackled on.
"You're having your first nipple orgasm!" Luna said with delight, stimulating the nipples in the way she knew was best. Cho was panting, moaning and squealing as she came through her nipples. "Incredible! Keep wanking my nipples please!" Cho pleaded, and Luna was happy to obey. "I can't t-take it, fuck, too good, cumming, nipples are cumming!" her words were almost incoherent as she rode out an uncontrollable orgasm, and Luna knew exactly what she was going through. Myrtle cackled like mad, but the sight of Cho cumming set the Ghost off, and with a shrill moan, Myrtle had her own nipple orgasm, violently shuddering as waves of pleasure took hold of her. Luna felt a little sad that she didn't get to cum yet, but she was with naked girls and had her body smothered with shit, and that was the next best thing.
Luna shuffled backwards and opened her shit smeared legs. "I'm gonna piss lots, Cho!" she gave a quick warning before releasing her bladder. Luna always had a powerful jet of piss, and Cho was in it's flight path. The Asian set up, letting the stream of piss fall over her tits and chubby stomach, then down to her pussy. "It's so warm!" she said, loving the sensation. Myrtle watched on rubbing her Ghost clit, Cho looked up and saw and wished she could touch her. Luna was covered in shit and Cho was covered in piss, and the sight and smell sent Myrtle into another orgasm, this time vaginal and the ghost sprayed glittery cum across the two girls who showered in it, wishing it was real girl cum they could taste. "You're such a disgusting whore, Luna. No one makes me cum better than you." Myrtle said, somewhat aggressively. Luna gave her a proud smile, watching as Myrtle dressed herself and floated off without a word. "She's probably gone to spy on boys wanking in the toilets." Luna said to Cho, and the two girls let out a laugh.
"Speaking of boys wanking, I haven't introduced you to Neville yet."
