Use Buffy from the outside

Willow looked down over Buffy's body. She decided that she would rather use the slayer's body from the outside.

Xander opened his front door, only to have Buffy shove him aside and close the door. Before he could get a word out she grabbed his wrist and pulled him toward his bedroom. He noticed that she was carrying a thick sack with her, which seemed to be full of something heavy.

“I need you do to something for me, and I need you to not ask any questions.”

“Uh... ok, what?” stumbled out Xander, being pulled into his room as Buffy tossed the sack onto his bed. She opened the sack and dumped it out onto the bed, revealing it to be full of strong looking chains and some heavy padlocks.

She pulled him over and kissed him, holding him for a few moments despite his attempt to pull away. She stepped back a few feet and took off her dress. “I need you to take those chains and wrap them around my body, then lock them in place so that I'm nice and helpless,” she said as she slowly removed her underwear.

“What? Buffy, I”

“I said no questions,” interrupted Buffy, stepping forward again and putting a finger over his lips.

Xander looked over the now naked Buffy. This seemed obviously wrong, but he was being offered too much. He gently pushed Buffy onto the bed and rolled her onto her stomach. He pulled her wrists behind her back, crossed them, and wrapped the chains around them. He padlocked them in place, then wrapped more chain around her arms and chest, just above and below her breasts. He crossed her ankles and chained them and her legs together, locking it all in place.

Almost sensing what he would be asked next, he grabbed one of his t-shirts and tore a thick strip off of it, and used it to gag her. Buffy took it willingly, moaning seductively.

Now Willow had what she wanted. She switched bodies, moving into Xander. She watched as Buffy slowly came back to, realizing the situation that she was in.
