Take over the Harpy

You didn't know how Blue would do that, considering the Harpy had miss Liz trapped under her talons, literally. If any of them made a move, the Harpy could hurt the witch! Seemingly ignorant of this simple fact, the blue blob started jumping a bit closer towards the harpy, 'standing' between you and her. Then Blue started jumping up and down, left to right, as if preparing itself for a feint and an attack.

"Blue, stop!" you yelled through your mind link, "don't provoke the harpy!"

Blue ignored your order, keeping at it. The harpy quickly took notice of the slime, but she didn't seem to be overly concerned. She scowled at Blue, but it was more from annoyance rather than anger.

"You... stupid... follow... human"

The harpy barked, her beautiful voice in stark contrast with her rough speech. It didn't seem like she could speak the Common Tongue well, probably only what little she could learn from her prey in the past. Blue didn't react to her words and kept jumping around. You were dreading this interaction until you noticed something else in your field of vision.

Blue's split part came to the rescue and headed towards the harpy without her noticing, her attention fully focused on the larger jumping slime. However, from where it appeared baffled you.

"Did... did your split part just come out of miss Liz's mouth?!" you couldn't help but asked in surprise.

"Yes," Blue responded calmly.

"You were possessing miss Liz?!"

"We can talk later, master. I need to concentrate"

The smaller Blue climbed the harpy's talon and slithered onto the feathered leg, and she didn't seem to realize it. That was, until Blue reached her human-like thigh. She shuddered, definitely feeling the cold slime suddenly touching her bare skin. She turned to look down at her leg, and that was when she finally realized that something was crawling on her. She shrieked loudly, letting go of Elizabeth as she flapped her wings and tried to shake off Blue. But it was too late; Blue had already crawled up onto her pussy, and started invading her body.

The harpy was already flying mid-air when Blue got inside of her, and she crash landed with a loud noise against the side of a house. She leaned her back on a wall for support as the sensation on her nether region was too much for her. Her whole body stiffened up and her eyes rolled upwards as Blue's cold body **** itself further and further into her. The small blob of slime finally fully disappeared into her vagina after a few moments. The harpy felt like someone was pouring ice water straight into her womb, before it started to spread to all over her body. Her chest heaved rapidly as her heart beat faster and faster, struggling to circulate the chill slime through her veins.

Within seconds, the harpy's body had gone completely numb. She slumped back against the wall, her legs and wings twitching weakly. As the harpy was struggling, you crawled towards miss Liz to check on her condition. It seemed the harpy's talons stabbed through Elizabeth's stomach, but it wasn't that deep. Elizabeth was ****, but fortunately it didn't seem like her life was in grave danger. You quickly scrambled for the bag of potions you had been carrying and poured some of the rejuvenating liquid onto the wound.

After treating miss Liz's to the best of your ability, you returned your attention towards your surroundings. No other monster was approaching you and miss Liz, they were busy fighting the other adventurers. Suddenly, you heard the sounds of wing flapping right behind you. You looked back and saw the harpy towering over your kneeling body, her figure looming over you and miss Liz. She was smiling at you, but not the sinister kind of smile she did just moments before. No, she was smiling sweetly and genuinely, flashing a row of sharp teeth. A few minutes ago, you'd be absolutely terrified of this situation, but you were just quite nervous of the murderous bird since the harpy was already under Blue's control at this point.

"Hello, Alexis," the harpy said as she leaned closer to you.

"H-hello"

You greeted back, flinching a little when the harpy's face was right in front of you. Even though you knew it was Blue controlling her, seeing a harpy so close still unnerved you a little. You had never seen one in person before after all, and it was about to hurt you before.

The scream of one of the adventurers brought your and Blue's attention back towards the skirmish. You'd like to help, but with miss Liz knocked **** you could not afford drawing attention towards you like before. The harpy, acknowledging your worry, spoke to you in smug confidence.

"Worry not, master. I'll handle the rest of the monsters"

You didn't argue with her. Harpy Blue leaped off and immediately began fighting the remaining monsters, butchering some of them in no time. It looked like a harpy was a much stronger monster compared to most of those attacking the church. The defending adventurers were quite confused when they saw a monster killing its own allies. You managed to convince them not to attack Harpy Blue by shouting at them.

Once the monsters were dealt with, some of the adventurers helped you carrying Elizabeth over to the church. Abigail, the priestess from before, thanked you and helped treated Elizabeth's wound. Soon, you and several adventurers with small injuries returned to the front of the church and guard the entrance again, with Harpy Blue keeping watch from high above on top of the church's roof.

About an hour later, the sounds of battle had quieted down. You could only hope that it meant the monsters were either wiped out or chased off, because the alternative would be terrifying. No monster came towards the church after the first attack, thankfully.

Then sometime later, a group of soldiers passed by the church. They were doing a sweep, searching for any monsters that might still be lurking around inside the town. When they noticed your harpy perching on the roof above, the solders were about to attack her with their bows and magic, but you quickly told them that she was on your side. The soldiers were understandably **** to believe you at first, and when you told them you were a monster tamer they argued that no monster tamer should be able to tame a harpy. However, the other adventurers who were with you guarding the church also vouched for you and your harpy, so the soldiers had **** but to lower their weapons.

A few of the soldiers stationed themselves on the church, giving you and the others a moment of rest. You decided to get inside and check upon Elizabeth. She had regained consciousness and was helping the clerics distributing potions.

"Miss Liz," you called out, "shouldn't you be resting?"

"I'm fine," Elizabeth replied, "and besides, we need every hand available"

You were too tired to argue decided to rest instead. You sat down on a nearby pew and rested for a while, watching the wounded getting healed, the slime Blue on your lap. Their cold body was quite comforting. Eventually, you fell asleep.
