Sometime between passing out in the middle of the Fairy orgy, Oliver was woken by a soft feeling against his member. The clearing was almost completely silent. Carver and Cassandra were unconscious in sticky heaps of sleeping, well satisfied fairy girls who'd all returned to their normal ridiculously small size after falling asleep. Gabrielle wasn't in the clearing, and Oliver figured she, the former Alp, and the Fairies he'd sent to have fun with them must not have made it back to the clearing before they started having fun together, which honestly wasn't much of a shock to him.
He looked up to see what had woke him, and saw that it was another fairy, the only other thing awake in the clearing. She looked different from the other fairies. Instead of wearing the same earthly green all the others had on, she was wearing some sort of deep blue leotard that hugged her body tightly. Her hair was light blue with what looked like small horns poking from the top of her forehead. Her wings moved silently to avoid waking anyone.
Also unlike the others, she didn't change her size before touching Oliver, rubbing her small feet against his cock to try and stir it to life. He doubted she'd be able to, both because of how tired he was, and because it was hard to be aroused by her smaller form. But when he looked at her face, the lustful smile she gave him was too enticing for his body to ignore, and his member started to stiffen.
The Fairy smiled, and to Oliver's dismay, flew away from him. She only flew to the edge of the clearing though, waiting there for him. She beckoned him over with a mischievous smile. In most circumstances, Oliver would not have fallen for this. Even as tired as he was, his groggy mind seemed to notice something wrong with how she looked and how she acted, but he was tired enough that another of those enchanting looks of hers drove such thoughts from his mind entirely.
Oliver got up and followed the fairy girl through the trees. It was hard for him to know how far he walked before she stopped him, motioning for him to sit back against a tree. Her looks seemed to have some sort of control on him. Actual magical control, and even being semi-aware of this didn't change weaken the control she had. He sat down against the tree, solid cock sticking straight up for her.
She flew down, bringing her body close to his rod. Her arms and legs wrapped around the length so she could hug herself close to his stiff meet, rubbing it with her entire body. Watching her do this was a bizarre mix of cute and sexy that his magic drugged mind couldn't fully process. She pulled herself up more towards the top, licking and sucking his tip, even pushing her small tongue into the slit of his cock.
He shuddered, cock twitching from the feeling of her tongue inside. Feeling this twitch, the fairy grinned, pushing her tongue deeper as she rubbed her entire body against his cock, stroking it with her arms and legs at the same time. She moaned against his cock as she her hips bucked against its shaft, her tongue swirling inside of it as she sucked the tip as though making out with his member.
She barely lifted her head in time to avoid being blasted off of him by his cum. Her face was completely covered, and in the brief moment he couldn't see her eyes or her smile, the word came to mind and he understood what was happening. 'Pixie.' He thought. They looked like Fairies, they acted like them to trick humans. But they weren't Fairies. Fairies ran on entirely pure magic, technically making them separate from Mamono, same as human mages or Elves. But Pixie's ran on demonic, sexual energy, same as any other monster girl, and they harnessed it through incredible seduction powers.
Oliver had read about them, even seen one who'd been trapped in a jar to avoid her corrupting the local fairies, but had never been ensnared by one before. Knowing what she was and what she was doing didn't make him immune to her charms thought, and the moment she smiled up at him, he was back under her spell once more, holding perfectly still for her.
Her outfit vanished magically off of her body, leaving her naked. She flew down and held onto his cock again, this time grinding her pussy against it, moaning as she more literally rode his cock. She bucked her hips hard against it, the sound of her moans even more intoxicating than her smile. Oliver could feel the wetness of her small slit against his cock, and felt that he might just be with her forever.
Thankfully, Gabrielle arrived. A single, wordless spell broke the Pixie's hold on him. The Pixie flew off of Oliver before he could do something to get revenge on her. Gabrielle was naked, her chest and cock covered in kiss marks from the Elves. Seeing her cock, which was still stiff as a board, the Pixie smiled at her to try and tempt her as she flew close to the white mage.
Unfortunately for the Pixie, Gabrielle was entirely the fuck done with fairies for the night, and was having none of the pixie's shit. She grabbed the Fairy around the stomach, and pulled her down hard onto her cock. Fairies and Pixie's both had a uniquely... stretchy quality, that make fucking them in their small forms entirely possible. But it was still shocking to see, especially with how large Gabrielle's cock was.
The Pixie let out screams of painful pleasure as her body was stretched and contorted in ways no non-magical body could be moved without several things breaking in the process. Gabrielle groaned, evidently using the Pixie to let out more than a few frustrations. She dropped he Pixie after she came, having filled her entire fucking body with seed, as well as painted her from head to tow. She lay twitching in a puddle of cum she could probably have swam in were she still conscious.
Back at the clearing, Carver was now being woken as well. Similar to Oliver's being woken by the pixie, the cobwebs in his tired mind let him overlook the glaring flaw in what he was seeing. He could see Cassandra out of the corner of his eye, sleeping underneath six or so sleeping fairies, so seeing Cassandra standing directly above him would have been cause for him to attack if he were fully awake and had any weapons within reach.
Instead, he simply wondered why Cassandra's clothing and skin looked so moist. She smiled at him, and lowered into his lap, grinding down against his member. The oddly smooth feeling of her skin against his brought him to full stiffness quickly, and he moaned as her soft, wet, sticky hole enveloped his cock for her to begin riding him as he held onto her hips.
'Wait..' he thought as she rode him, 'sticky..?' It was now he realized that Cassandra was off to the side in the clearing, and whatever was riding him was most certainly not her. The shock of this did well to wake him up. He tried to take his hands off of the imposter, only to find the skin was semi-liquid, and wouldn't let him go. He now remembered what the party had been told about the slime mamono in the area getting more aggressive.
Seeing that she'd been found out, the slime monster girl allowed her form to return to normal, revealing her ghostly white/light blue skin, dark inky hair, and thick blue slime drops that dripped from her body like massive globs of sweat. She moaned as she continued riding him, as though thinking he wouldn't care that he had been tricked and would simply enjoy the fun.
Granted, the more instinctual side of him considered it, but he couldn't allow himself to be used by a mamono, and tried to stand up to force her off of him. Unfortunately, the slime her body was made of had more or less glued them together, and all his standing had done was change their position. The slime girl didn't seem to mind, moaning happily as her hips continued moving.
Carver tried to wake Cassandra for help, but the tired martial artist didn't really wake up, simply opened her eyes and grumbled. Near as Carver could tell, she'd said, "..just a Nureonago.. let her finish.." before closing her eyes to continue sleeping. Carver had never even heard of this species of monster girl, but supposed that if it were dangerous, Cassandra would have had more urgent a reaction.
Unknown to him, Nureonago were even more docile than normal slime girls, normally quite polite. Even when fully savage, the worse they got was stalking a human they liked and begging for sex. This one had been driven to the point of actually forcing sex onto the nearest human by whatever force was working up the other slime mamono in the area, but it wasn't nearly enough to make her violent. Carver grunted as her semi-liquid pussy squeezed him harder, and began willingly thrusting into her, knowing his body would probably be even more sore the next morning.
