After not being able to find Weiss, Winter Schnee began trying to find her on her own, taking her special weapon with her as she had to make sure she was safe "What does my sister think she is doing?" she asked herself as she looked around the Academy. However, the white swordswoman had found what she was looking for in the most wrong way possible, the heiress Weiss was sucking off 3 children sized Grimm though guarding her was a hooded figure, it was Grane. Winter growled and pulled out her sword "What are you doing to my sister!?" she growled, being protective over her despite the fact that she can prove to be quite cold "That's disgraceful to the Schnee family!" she exclaimed and used her Glyphs to enhance her speed to attempt a strike on Grane though he countered it, forming his black arm into a tendril which tripped Winter in midjump though she did catch herself. "W-Weiss wake up!" Winter told her sister and tried to run for her, being stopped by a Grane who tackled her, smashing her through trees. "T-that's it" Winter stopped the impacts with a Glyph then knocked Grane back, using a glyph to keep him from moving "You will pay for your crimes against my sister!" Winter exclaimed and summoned a Nevermore.
Grane looked up at the Nevermore which crashed into him, white powder flying everywhere upon impact as Winter panted softly, the fight ruining her clothes a bit. However with the threat gone she could focus on Weiss now, running towards her and warding off the Grimm children "Weiss are you okay?!" Winter wiped her face of some of the cum so she could look upon her sisters face, worried that their father might think less of them now. She turned her sister to see her clearly though the only thing that was physically different was Weiss's breast size, she first had B sized breasts but now she had double dd's, and also her belly was larger "A-are you pregnant?! who did this?!" Winter scolded her sister who only gave a small giggle. "I let him do this to me...I was devoid of loving and he showed me I can be more than what I was, a simple heiress who is no longer dying for affection" Weiss said, being cryptic "W-what are you talking about?" Winter shook her sister though she was surprised that she was kissed roughly by Weiss.
Winter resisted her advances but Weiss was surprisingly much more stronger than her physically, Weiss licking her tongue as Winter began getting wet "D-don't do this we're siblings!" Winter pleaded while Weiss put her on her back. "Like that should really matter" Weiss said and silenced Winter by shoving her cum filled pussy in her face, she couldn't breathe so in order to breathe she had to eat her own sister out. "A-ah I-I think shes ready for rehabilitation Grane" Weiss told her, groping her boobs as she came in Winter's face "Make sure she doesn't escape" Grane told Weiss while shoving his cock all the way into Winter which made her squeal audible. Winter kicked and squirmed though she couldn't defend herself, Weiss moved her hips more while drooling, Grane starting to kiss Weiss while slamming into Winter hard and fast.
Weiss gripped onto Winter's and Grane's head, rubbing her sisters face in deeper while bringing Grane closer for a kiss which succeeded. Each thrust hit Winter's womb which made her twitch in pleasure, her morals slipping away as ecstasy filled her mind instead. Winter came from the thrusts as Weiss came on Winter's face once again "M-master m-my sisters tongue is so naughty!~" Weiss laughed softly then lifted her hips so she could see a dazed Winter, showing slight signs of resistance. Grane smirked and held her thighs, slamming hard into her hard and fast making Winter scream in pleasure though she was silenced by Weiss's kiss and to her surprise, kissed back which meant Grane did break her as well as Weiss who did her part.
"Good job Weiss, I shall reward you" Grane told her then put Weiss on top of Winter as he came gallons inside her, making her drool from how it felt inside her though she did cum with him as well "S-so hot". Weiss kissed Winter softly while Winter spreads Weiss's ass for Grane, who penetrated her making her arch her back fast "T-take it little sis" Winter told her while Grane began switching between Winter's pussy and Weiss's ass, both hugging each other and kissing each other to contain their loud moans. Grane held onto Weiss's large boobs while slamming into the pair of Schnee's "I-I would be honored to have your semen in me G-grane" Winter barely managed to say while Weiss sucked Winter's smaller breasts.
Grane drooled while starting to lick Winter's tongue with his own tongue, who rocked her hips against his rod while Weiss gripped onto Winter's shoulder before cumming on Grane. They all came hard at the same time and screamed each others names, Grane filling up Weiss's ass which leaked onto Winter's pussy which was flowing with white liquid, Winter passing out from the pleasure "Aww sister needs modifications too..." Weiss said and crossed her arms, standing up. "Come Weiss, we got our catch" Grane told her then stood up, attaching Winter to him with his tendrils. Weiss smiled and ran towards the Emerald Cave, being followed up by Grane.
~Emerald Cave~
Grane had managed to form a Cytopod, a byproduct of the Grimmcyte virus which looked like black sludge and for faster modification using tendrils he put Winter on the sludge. Winter began waking up and noticed that she was covered in black sludge though her head was completely clean "W-what the hell is this?" Winter growled at Grane who fingered her through the sludge. "This is a Cytopod, we modify our mates so they can be enhanced in both stamina and strength as you can see here" Grane told her and moved over, Nora, Pyrrha, Weiss and Yang all being fucked ruthlessly by their own children. "Y-yes f-fuck me dammit!" Yang told her newborn child who came gallons inside her pussy, rubbing her boobs. Pyrrha was riding on top of a teenage child, bouncing her hips faster while lickig the teen's tongue. Nora had a horse member inside her pussy, the tendrils taking the form of a horse so it could maximize pleasure and Nora only drooled, being able to take the immense size while licking another horse member carefully. Weiss had her ass and pussy penetrated from behind, sucking off another child as she had her foursome with her children "T-that's right I-I'm your momma, use me". Winter was horrified which made her growl more "That's my sister!" she told him "And also my wife now, soon you will be too" Grane told her and smiled.
Winter was in a position where her arms and legs where to her side, it was like she was sitting on a floaty but what kept her in place was a tendril wrapped firmly around her stomach. "W-what is I-it doing to me!?" Winter drooled as she could feel her pussy and ass being prodded by tendrils "Well think of it like this, the Cytopod modifies a persons stamina, strength but also for females give them bigger breasts so they can feed their young" Grane explained and stopped fingering Winter. "Now, your arms and legs aren't restrained but that doesn't mean you can escape, that's suppose to make you more comfortable and every 10 minutes the Cytopod will dip you so you are used to sexual fluids produced" Grane told her as the tendrils pushed into her pussy and ass making her scream "Your body will always stay like this without me needing to reapply this so this method works much more than simply cumming into you" Grane told her. After several minutes of thrusting into Winter, the Cytopod began 'dipping' Winter. The Cytopod had 2 parts, the upper mouth and the inner hollow chamber which was covered with sentient tendrils but also pores so cum supplied by Grane could enter, essentially the Cytopod was gonna make Winter hold her breath under gallons upon gallons of cum to train her lung capacity. Winter was brought down under the cum, bubbles popping up occasionally and the mouth closed leaving only her feet and hands visible, the mouth closes when the dipping started so the victim couldn't escape while the process was done.
After a whole minute, Winter was finally let up though she was completely drenched in cum, to the point the only visible part was her mouth "Don't worry, you'll be quite happy here" Grane told her and rubbed his member against Winter's tongue, who began sucking him off. Grane began letting out a laugh though he needed more wives to have as allies in his plans, he had some in mind.
