Ruby had been looking all over for their sisters, the museum was holding a weapons exhibit and because of her fascination of them she begged her sister to come with her. "Yaaaaang! Come on we're gonna be late! Huh...maybe if I call her" she told herself then pulled out her phone, dialing her number and what she got was no answer. The young huntress then made her way to Emerald Forest, getting tired from searching all over Vale for her beloved sister "Yaaaaang!".

She heard a twig break in the forest and she pulled out her signature weapon, moving closer to the source only to find out it was Yang, gathering berries. "Yaaang!" Ruby ran at Yang and tackled her, making her turn around to face her. Yang gazed into her sisters eyes, if she asked too many questions she would have to incapacitate Ruby even though she didn't want to.

After being nagged for several seconds Yang lost it and kissed Ruby, the black and red haired heroine eyes widened, at first clawing at Yang's back but eventually stopped after she passed out from the kiss which lasted for 5 minutes. Yang wiped her lips and could feel her lust for Grane coming on just from kissing someone that wasn't her husband "G-Grane" she whistled for him to come.

Grane soon arrived and looked at the fallen Ruby "Well done" he told Yang which made her bite her lip "T-thanks!" she nuzzled him while Grane slapped her ass "Lets get these bothersome clothes off her" he told her. They began stripping the younger sister until she was naked, Grane not being pleased with the condition of her body. "Yang, we will condition her, loosen her up" Grane ordered Yang who nodded, getting down on her knees and eating out Ruby, swirling her tongue around in her pussy.

Ruby slowly woke up, her body feeling hot and after searching she found the source, her own sister was licking her insides like it was nothing though she did try to fight it, it was extremely good. Grane decided to reward Yang and surprised her with his dick in her pussy, making her scream against Ruby's pussy while grabbing her jiggling ass with her free hand.

The scythe wielding huntress moaned loudly and held Yang's head down, who held her ass cheeks open so her husband could ram into her as hard as possible which made her drool mix in with Ruby's juices. Yang licked harder and faster as a result of being pleasured by her king before finally cumming against his plunging cock, Grane cumming straight into her womb which gave Yang a pregnant appearance.

"G-guys!" Ruby cried out as she finally came on Yang's tongue, who slipped her tongue out while slightly panting "G-Grane?" Ruby gulped, remembering that Grane didn't look like that, nearly his entire body was black except his eyes which were human but had those red orbs, staring into Ruby's soul. Grane smirked and grabbed Ruby's neck "Now, I think its time to give you pitiful body some conditioning" he told her before slamming her onto his large cock, making her scream loudly as she clawed at his back.

Yang laid Grane on his back, allowing her to sit on his face as he cleaned her insides with his large tongue while Ruby drooled from being thrusted into with intense force. To spice it up Ruby had a tendril go into her ass while a large tendril went into Yang's mouth, who sucked eagerly as it was apart of Grane. Ruby screamed loudly but was muffled by a tendril that went into her mouth, Grane ramming his tendrils and cock into Yang and Ruby while licking the yellow huntress's pussy.

His throbbing member scraped against the younger sisters wet insides, who slowly rode against him while Yang pushed his face deeper, licking the tendril softly while Ruby rubbed the tentacle in her mouth with her tongue. Grane stroked their insides with his members while licking Yang's pussy greedily, hitting Ruby's womb as he was about to cum in her however Ruby was hit back by an unseen force which made the cum that was suppose to be for Ruby, erupt like a volcano.

Somehow, probably through her advanced physical capabilities, Yang caught the cum in her mouth as she burped a bit, smiling to herself. Grane however quickly shrouded himself with Grimmcyte virus before getting on his feet, looking behind him and seeing a Glynda Goodwitch, preparing to attack Grane. "You...these females have been defiled long enough Grane..." Glynda said and aimed her weapon at him.

However, she was struck down quickly by Yang, though she didn't get knocked out from the blow. Glynda recovered and flipkicked Yang back but was hit against a tree by Grane's tendril before lifting her up by the neck, breaking her weapon with his hand "Well great...Ruby is gone but at least I got you" he licked Glynda's cheek with his long tongue "Yang, head home and prepare a cytopod, we have conditioning to do" he told her and she only sighed "Yes sir..." Yang dashed off.

Yang had an ulterior motive, she wanted to assist her husband in the plans of world domination but to create children with those her human self and Grimm self don't trust didn't sit well with her. Ever since Cinder came into the picture she was all over him, she got more time with him than Yang. Yang was jealous, Grane could fuck other girls as long as he stayed with Yang the longest but because of the need for mass reproduction she couldn't maintain being the only mother giving birth several times a day.

She wasn't a thinker, but she needed a plan.
