Masako sat alone in the library, her blank notebook open in front of her. She was an introverted student who preferred to spend her free time reading and writing. As she sat there, lost in thought, she didn't notice the two small succubi that had appeared behind her. The two succubi whispered to each other, discussing how they were going to possess Masako. "She looks like a perfect vessel for us," one of them said, grinning wickedly. The other nodded in agreement. "Let's do it," she said, and one of them approached Masako. Suddenly, Masako felt a sharp pain in her back, and she cried out in agony. The succubus had possessed her body, merging with her and taking control. Masako felt like she was being suffocated as the succubus used her body to tease and taunt the other succubus who was watching from the dark. "This feels amazing," the succubus inside Masako's body said, giggling. But then, the second succubus wanted a turn. "Let me in too, let me feel it too," she pleaded, eager to experience the sensation of wearing Masako's body. As the second succubus enter Masako's body through her pussy, Masako body convulsed in pleasure as she felt the second succubi slipping inside her. She could feel the two succubus taking control of her body, using her voice to tease and taunt each other inside Masako body. With both succubus inside her body, Masako was now nothing more than a vessel and a disguise for the two succubus. Her mind were trapped, helpless to resist as the two demons controlled her every limbs to move around.the library The library was now silent, except for the sound of Masako voice as the two succubus used Masako body to exit the library through the door. No one else was around to witness the horror that had unfolded. Masako was alone with the demons inside of her body, trapped in her own body and she became a vessel for their wicked games, trapped forever in her own flesh prison.
