Ruby gets full control of her, and she has a humilation fetish!

Weiss yelped, and Yang's magic, in the form of shimmering violet mist, swirled around her. Her clothes disintegrated, and reappeared folded in the pile with Ruby, Yang's, and Jaune's. And a silver collar appeared around her neck, a glowing sapphire encrusted in it in the front. "What the fuck!?" Weiss shrieked, initially covering herself, before trying to remove the collar, hiding her arousal at the situation behind half faked rage. "What did you do!?"

Ruby moaned as she continued to stroke herself, knowledge of what the spell did flowing into her mind. That collar gave Ruby full control over Weiss, and she learned that Weiss had a strong fetish for being humiliated. Nearing the edge of climax, she stood up, her hand going faster over her shaft. "Weiss, kneel in front of me!" she panted.

"Like hell I will, Dunce!" Weiss stated, before yelping as her body moved on its own. "What the!?" she demanded as her feet, against her conscious will, but fully in line with her subconscious desires, carried her over to in front of Ruby, and she dropped to her knees in front of the masturbating futa, blushing furiously as she saw her dick pointed right at her face. Unwilling to admit how much she wanted Ruby to paint her face in cum, she tried to get up, but her body refused to listen to her less honest side. "Don't you dar-!" she started to protest, but Ruby grunted, and moaned as she came, jets of semen shooting out, and spattering against Wiess's face, the first emission going directly into Weiss's open mouth.

Weiss gasped, and tried to turn her head away, but even that motion was denied to her by her own desires having control of her body. Consciously, she still had the inhibitions gaslighting her into thinking this sort of thing was imroper, that she shouldn't want it, but she was also aware of just how... hot it was! Ruby panted as Weiss was quivering. Whether it was due to impotent rage, or her secret delight at the treatment, even Weiss wasn't sure. "Heh, you look so sexy like that..." Ruby grinned. "How are you feeling? Answer honestly," she ordered.

"I feel great, Mistress!" Weiss's mouth gushed before she could even try, and fail, to stop it, pouring her heart and arousal out to Ruby. "Please, humilate and use me more!" She blushed and looked away, unable to believe this was happening, and unwilling to admit that she wanted it to continue.

"...wow, is she really a masochist or something?" Jaune asked, getting up.

"Oh yeah, she is~!" Yang grinned, before looking imploringly at Ruby. "Mistress, may I please spank her, and make her apologize for every hurtful thing she said to you?" she begged.

Ruby looked between Weiss and Yang thoughtfully.
