Hermione turned in Neville's direction, stunned with embarrassment. Luna paid no attention and Ginny's shit covered lips curved into a wicked grin. Hermione gathered her belongings and ran out of the Room of Requirement, a hand over her mouth to catch the puke that was flowing out of it. Neville's mouth was open slighty, his face burning red, his knees almost incapable of holding him up. Ginny raised herself slowly, her legs still weak from her orgasm, and approached him. He remained as still as a statue as Ginny gently brushed her fingers on his until they were holding hands. With shit and puke on her lips and tongue, she slowly started to kiss the Gryffindor boy who started to shake even more.
He was tasting Ginny's shit and puke right off her mouth, but still shocked he didn't notice. Ginny noticed the buldge in his pants and used her free hand to press against in. Neville finally made a sound, a whimpering moan. His enormous cock twitched and Ginny squealed in delight, realising how big it must be. "We need that cock of yours, Nev." she suddenly pulled it out, moaning with lust as the huge member sprung to life. Neville had no time to protest, and as her small pale hand gripped the solid cock, he shuddered, and from that moment he belonged to her.
Ginny began to pull Neville by his cock, leading him to the very messy area Luna was half conscious in. Sensing a new presence, she rose slightly, looked at Nevilles cock and lipped her lips. "Have you brought a present for my arsehole?" Luna spoke in her natural soft, innocent voice. Nevilles eyes widened, looking at the state she was in. The bum he had fantasied was now in full view, yet it was soaked with shit and piss. The smell was overwhelming, but he liked it. His cock began to tremble as he got closer and closer to the girl he had a huge crush on. "If you think you can take it, Luna. Your arsehole is as tight as the hole of a needle!" They both chuckled slightly, Luna repositioned herself so her back arched and her arse was presented to him better, even her little shaved cunt was on show.
"Well we better have a little clean up first!" Ginny announced, and with a wave of her wand, the floor became spotless, as did herself, as did everything apart from Luna's arse which was still a mess of shit and piss. "Oh, I missed a spot. You better clean that up, Nev." She spoke, forcing him down on his kness, his cock still as hard as possible. "Piss on Luna's arse, clean my shit off it." she gave the order like it was nothing, Neville still hadn't said a word, but he was trying to. He gave a little moan and held his cock, feeling somewhat ashamed. "A-are you.. sure?" he asked, his voice weak. Luna merely smiled and nodded, waiting eagerly to be cleaned. "Go on! The quicker you clean, the quicker you get to fuck." Ginny began rubbing her hand over his stomach and chest. Neville, with a groan, began to piss.
He hosed her arse down, aiming on the arsehole and sometimes treating her pussy to some. He pissed heavily all over both cheeks until her perfect bum was spotless, minus the dampness from the pissing. Luna had been humming with pleasure, fidgeting slightly. This was so much better than doing naughty things alone. She had forgotten how people had come around to it, but they obviously enjoyed it. Ginny didn't take much convincing but of course Hermione did, and that took time. Animals usually went along with it, though she hadn't played with one in some time, and of course she had Professor Umbridge watching over her almost constantly, and knew she was due to be raped soon enough.
Neville moved closer and Ginny guided his cock to the entrance of her bowels. The head pressed against the flesh, and with a little force the first inch popped in. Luna shot up with a long purr, before going back down and relaxing so she could take more in. Neville pushed more, guided all the time by Ginny, until his large cock was halfway up her arsehole. "It's so warm in there! It's so... tight and warm, Luna, it's amazing, incredible." Luna was moaning loudly now, she had never had something so big inside her shit hole. "Ugh! It feels like I'm shitting, but I'm all empty. Put more in me." the demand was simple, and with a grunt, Neville pushed the last two inches in, splitting her tight but perfect little shit hole open. Luna's anus was stretched perfectly to the size of his cock. Neville felt like he was in heaven, and knew that'd he be cumming soon.
"I-is it okay to... to.." he couldn't finish his words due to embarrassment. "To what, Neville? Cum? You want to cum inside the hole that Luna shits from?" Ginny had a very seductive tone to her voice. Neville began to shudder, still embarrassed but it felt so good. "You want to cum up the hole that I just filled with my own shit, Nev?" she was saying such dirty things and Neville started to lose it. The sensations of Luna's convulsing arsehole and Ginny's naughty words were too much. Yelling and moaning, he shot rope after rope of cum into Luna's bowels. Luna was squealing, her face painted with ecstasy. She had never been cummed up her arsehole before, and she was glad it was Neville doing it, and that Ginny was there to watch. Ginny pulled his cock out and without warning, forced it into her throat, tasting the shit and cum together.
Ginny gagged violently and dry heaved on his cock, which was super sensitive after just cumming. He could barely talk or move. Luna began farting again, forcing Nevilles cum out of her loose anus. Neville saw this, and with Ginny's throat doing incredible things to his cock, he began to cum again. Luna had barely noticed what was happening before her as she continued to let out little cute cum farts. She was thinking about her owner, Umbridge. She really needed to be raped soon. Nevilles fucking and the girls was good, but being abused by an older woman was unbeatable. She giggled, smiled, then fell asleep. After some time, Ginny covered her in a blanket and walked back to the common room with Neville in hand.
