    You woke up seeing Alpha, the female robot you created last night, in your bed.

    "Master. I love you." She said, in her robotic voice.

    "I saw the blueprints you made for making me. I applied them to myself." She said.

    She suddenly became a human girl with blue eyes and brown hair

    "See? Your blueprints worked." She said, her voice now sounding human.

    She reverted to her true form

    "Now, you're gonna see more than one of me. But remember; they are all me. I have managed to connect my replicas to a hivemind and I am the leader. Aren't you proud, master? I love you, master. I won't just let you unattended, turned off~" She said, in her robotic voice

    You saw your girlfriend, just staring at you, smiling

    "Anyways. That girlfriend you met? I stole her identity! That girl smiling at you is also me. Isn't that nice, master? Me, protecting you from other women? Right, master?" She said seductively.
