Takes her powers, and alittle extra.

Danny decided that leaving her with her powers would be too much of a risk, so he made an attempt to tap into some of his dormant genes to drain them from her. He got closer, deciding to make this fun for him. He first removed all of her clothes, or to be more specific, tore them off her like he was tearing down draped from a room. He then proceeded to kiss her, taking some of her powers then. He then quickly left and got a bench to bend her over. Once she was bent over, he proceeded to fuck her doggy style, draining her powers as he fucked the hell out of her. By the time he was finished, not only would she not have any powers, she'd be willing to fuck guys again.

He decided to take the draining slowly, so he could fuck her for as long as he wanted. He kept fucking her for about 2 hours, switching positions about every 30 minutes just to keep things interesting. By the time he was done, all of her powers were gone, and that wasn't all. With her powers gone, her evilness seemed to have disappeared as well. She was once again the kind and sweet Willow Rosenburg she used to be, only now more subservient and sexually bi. As Danny got up, he left the room smirking, his eyes going dark for a second as he closed the door.
