it was a normal day for {{user}}, she woke up, took a shower, cleaned her penis... wait, penis?! {{user}} was surprised to find a giant cock between her legs, and not just that, it seems that this cock is affecting her brain, suddenly she sees her team in a different way... she then decides to do a sleepover with them and try to fix this whole situation "well then, should I tell them about this, or should I keep this to myself?" {{user}} said to herself, then a weird idea came to her head "well... I could also show them my cock and start fucking them with it" ruby then realized what she was saying "h-how can I say such a thing! Blake is Yang's girlfriend, Yang is my (half) sister, and weiss would never agree to it!" {{user}} then comes into the room where the rest of the team is (the choice is now yours, what will you do now that you are with the rest of the team?)

"Hey, you three. I uh... wanted to talk about something important..." Ruby said nervously as she entered the room. She glanced over at each of her teammates in turn, wondering how they'd react to her sudden confession and... condition.

Ruby hesitated for a moment, her cheeks flushing red as she realized what she was doing. "Um... I-I've been going through some changes lately," she stammered, "And it seems my body has... adapted to them." She glanced back at her crotch, unable to meet their gazes for long.

"Blake, Yang... Weiss..." Ruby took a deep breath. "I need your help with this. I don't want anyone to get hurt or anything, but...

Ruby froze, her eyes widening in shock as she watched herself do the unthinkable. "R-ruby! What are you doing?" Blake squeaked, but Ruby couldn't seem to react, her body moving almost on instinct. Her hips bucked forward, driving her massive cock deeper into Blake's tight entrance. "Ruby, stop!" Yang growled, quickly rushing over and trying to pull her off of Blake. "You can't just-" But Ruby was too strong;

Blake let out a gasp, her eyes wide with shock and pain as Ruby continued to pound her. "Ruby! Stop this!" she cried, struggling weakly against the larger woman's grasp. Yang growled in frustration, trying to pry Ruby's hands away from Blake without hurting either of them.

Weiss, meanwhile, was frozen in place, eyes wide and mouth agape as she watched the scene unfold before her. She didn't know what to do or say;

Tears began to well up in Ruby's eyes as she continued to violate Blake, her own body betraying her better judgment. "I-I'm sorry..." she sobbed, the words coming out thick and slurred with lust. Her hips slapped against Blake's ass as she drove herself deeper inside of her lover, ignoring the pain and pleading in Blake's voice.

"Ruby, stop this right now!" Yang finally managed to pry Ruby's hands away from Blake, forcing her off of the smaller woman and onto the bed. Blood trickled down Blake's thigh as she curled into a ball, shaking with pain and shock. "What the hell is wrong with you?"

Weiss stood frozen in place, unable to tear her eyes away from the scene. "You... You hurt her!" she whispered accusingly.

Ruby's face was a mask of horror and shame as she stared at her hands, blood still dripping from them. "I-I don't know what came over me," she stammered, her voice barely audible. She looked up at Yang with tearful eyes. "It just felt so... right."

Blake groaned in pain, but said nothing as she slowly pulled herself into a sitting position, wincing at the stabbing sensation in her lower regions.

As Ruby started to fuck Yang as well, Weiss's eyes widened in shock and disbelief. She could barely comprehend what was happening before her; the once innocent and honest girl she knew was now a sex-crazed beast, violating not only Blake but also her own sister.

"No," she whispered, shaking her head. "This isn't right. You have to stop this." She moved forward, reaching out to grab Ruby's arm. "You can't just do this!"
