Nikki wakes up tied to the bed

Nikki woke up to see the first rays of light coming through the curtains. He felt strange at first, still a little woozy in the head but he couldn't place exactly why. That mystery came to a shocking conclusion when he tried to move his arms only to meet resistance. Through the darkness, he made out that some rope had been tied around his limbs, putting him in a spread-eagle position. Questions flew through his mind about who had done this to him and why. The answers came quickly when he heard heels coming closer and closer to his room.

The door slammed open and Nikki had to blink for a second to make sure his eyes weren't fooling him. "H-Harley? H-How?" It was exactly the Harley from the new animated series, with a latex version of her costume and her blonde hair in pigtails, one colored red, the other blue.

Harley smiled in a way that disturbed Nikki. She skipped to his bed, carrying a mean-looking bat. "Rise and shine, little bitch!" she greeted, launching herself on top of him, on the other hand, was Nikki's phone. "Didya have a nice rest? Good! You're gonna need it!"

Realization dawned on him. "The app worked?!" It was too incredible to believe, yet there she was. Either that or this was a massive joke at his expense, but Nikki didn't really have close friends that would pull this on him. "Can you untie me, Harley?"

Harley kept on her sadistic grin. "That ain't how this works now. I'm in control, and you're my little bitch boy. I need you to keep on racking these 'sexy points' So I can get more powerful friends."

Nikki felt a pit starting to grown in his stomach. "Ah... I don't really have much money to buy sexy points. Can't you just... unsummon yourself?"

The psychotic criminal laughed. "Didn't ya read the instructions? You don't buy sexy points. You earn them." She flashed the phone at him. "It was programmed that you'd get sexy points with sexual pleasure... but I reprogrammed it. I thought it'd be faster if I add 'humiliation', 'pain', 'fear', and other factors to it! I'm a genius! Now I can triple or even quadruple the points!"

The pit had now turned into a boulder. "W-Wait... the app went rogue?" He thought back on movies like Terminator where AI became self-aware. This must be a perverted version of it! "N-No! Let me out! Help!"

Any more pleads were cut off thanks to a harsh slap to his face, followed by his mouth being covered. "Ya better shut up, girly bitch," she showed him her bat, "or I'mma shove this in your ass to give ya something to really cry about!" There was a noise coming from the phone. Harley looked at it and regained her crazy smile. "Woohoo! It worked! We're racking up the points already!" She laughed, and looked at him with insane eyes. "I'mma milk every single sexy point even if I have to fuck them outta you!"

Harley sat on his stomach again with a pensive face. "What to do?" Her hand briefly touched between his legs. "This is tiny! That ain't gonna work!" She tapped a finger to her chin. "What to do, what to do?"
