He struggles

As soon he heard the... what could she be called? Program? App? The Harley he saw was truly unmistakable from a human, down to the, warmth of her body and odor of her feet. In any case, as soon as the villainess was gone, Nikki started to tug at his restraints before even looking at them. After an hour of fruitless struggles, he finally analyzed the ropes and saw that the knot was tied at the post.

It was hard, but Nikki stretched as far as he could towards the post on his right, nearly dislocating his left shoulder in the process but at least his fingers started to graze the knot. Unfortunately, Harley knew her knots well, and it took him the better part of two agonizing and intense hours to finally undo the knot with only one hand.

That done, he focused on the other wrist. With his right hand now free, this one took considerably less time. He then turned his attention to the ropes around his ankles and just as he was being finished with one, he heard the door of his apartment slam open. Panicked, he tried his best to undo the last knot but was unable to before Harley entered his room, humming a sugary sweet tune and carrying many bags. Once she saw him though, she dropped them all and frowned.

She launced her body on top of him, easily overpowering his feminine frame. "You're a disobedient little bitch, ain't ya?!" She wrenched both of his hands behind his back and used the discarded ropes to tie not only his wrists, but also his elbows tightly. Were it not for his natural flexibility, Nikki was pretty sure that something would have been either broken or dislocated. His legs were not ignored. Harley untied the last knot easily and used both lengths to tie his ankles and the other piece of rope went just above his knees.

"That oughta hold ya," sang Harley, going back to humming her song as she unpacked whatever it is that she had bought. Nikki paid little attention to it, too tired after spending the last few hours struggling to get free. Now he simply slumped on the bed until Harley laughed. Nikki looked up from his position, but he almost wished he didn't.
