Chimera Transformation (with story) (Patreon)

 "Hey redhead, you sure it's safe to go this deep inside the dungeon?"
"Don't worry, people said this cave's boss is dead, so we can grind some weak level monster to lv up."
"Well, my MP is going really low. I still think we should leave this place."
"Come on! We've reached this far. Also, a rumor said there's a legendary artifact at the end of this dungeon."
"You only care about money, don't you?"
"Tehehe, you got me ;3"

Two adventurers wander through the Chimera cave, trying their best to gain some exp and finding a treasure. But they don't even know when they chatting, a shadow slowly moves close to them with a smirk on her face.
"Oh hello, beauties. You two came right at the time I need a new subject for my experiment."
"What the... What out!"

...
Deep down the dungeon, there are two girls bound together by a golden nipple rings. A legendary artifact is right in front of their eyes, but they can't do anything. That artifact is two rings with the power of fusing anything they touch. Of course, it'll take time for living creature. Especially human, with strong resistance in their mind.  In the beginning, with both of the girls trying to fight back, they almost can escape the fusing power. But the lamia behind them won't let it happen.
She slowly put the priest to the hypnotic state, and without any resistance, she starts turning in to a goat-like creature. The goat girl fills with lust, and start to lactate. Her friend tried to call her name, but all she does is panting like a bitch in heat.
Redhead girl is not a good girl, so the lamia mistress has to train her well. The bad girl got her tongue pulled out, so she can't help but drolling all over her mistress's hand. To punish her bad attitude, her mistress uses her own saliva to lube and fuck her tiny butthole till she can feel good from it. With lust slowly burning inside her chest, her spirit gets weaker and weaker. 
The fusing process starts to work on their bodies. Their lower parts become one, with one pussy and one loosen asshole. Suddenly, the lamia feels someone has entered the dungeon. That must be two girls friends come to rescue them.
An idea crossed the lamia's mind. She smirks and pulls out a milk pump, then puts it on the goat girl's hand. Follow the lamia's order, she uses it on her own boobs and moaning while spurt out a huge amount of milk. With a tube connected to their asshole, her milk fills up their stomach and sharing their lust. Merging and corruption quickly affect the redhead. Light brown furs growing on her body with her ear changing to a lion-like ear. As she looks at her mistress's eyes, her mind slowly melting...

A high-level adventurer enters the dungeon. His sword easily cut through the monster body, but his face seems nervous. His blonde girlfriend has been here with her friend to grind some level and hasn't come home. When he reaches the end of the dungeon, he finally meet her. She's here with her friend, holding a shiny artifact. She seems hungry, so she cast a love spell on him making his sausage growing uncontrollably. They both having fun with each other day by day until he can't move anymore. Her tail changes shape and turns into a cobra, biting his neck and turn him into a monster. With the news about the dungeon's boss is back with the artifact, more adventures come to fight it. What they find at the end of the dungeon is the Chimera with many male and female bodies lying on the floor. As their mind has slowly taken over by the love spell, they find the purpose for the rest of their live. To worship their queen and protect her forever.

A year later, Chimera dungeon has become a SSS rank dungeon with a large number of monsters and 0% survival rate. A tall woman leaves the dungeon with a satisfied smile in her face.
