Ruby wishes to become a futanari

As she looks at the harem of girls in front of her, Ruby can't help but think she could enjoy them more with the right equipment. On some lonely nights she'd look up some hentai and came across the idea of futanari and wondered what it'd be like to be one.

"Jinn, I wish I was a futanari. Oh and that I can cum as many times as I want with no issues." Ruby wishes. Jinn's eyes go as wide as her smile.

"Absolutely my mistress. You are more than welcome to try it on me." The genie replies as she crawls over to Ruby. Jinn kisses the top of her mistress' pussy, her tongue focusing on the clitoris as she pours her magic into it. Ruby moans as it begins to feel warm and pulled as Jinn sucks on the clit, making it stretch longer in her mouth as it is turned into a thick 8 inch long cock. Underneath the cock Ruby feels two baseball sized testicles grow as well. Jinn pulls her head back, her saliva giving Ruby's new cock a slick finish.

All of the girls are locked onto the new member, each one wanting to feel the cock inside them. They take after Jinn as they all get down on their hands and knees to crawl over and they all begin to kiss and lick Ruby's stem. Ruby moans loudly at the amount of stimulation coming from the 3 girls, greatly enjoying the sight of those 3 slobbering over her cock. Weiss gets bold and takes the head into her mouth as she tries to deep throat the cock. While she is eager, Ruby's size gets the better of her as her gag reflex makes her pull herself off coughing. Yang can't help but chuckle.

"Looks like Ruby isn't the only one who's cocky." Yang puns, getting a groan out of Ruby.

"I'd like to see you do better!" Weiss says with a pout. Yang just grins at the challenge as she takes position in front of Ruby. She leans into Ruby's balls, kissing and licking them as she moves up to the shaft and licks her way up it. She spins her tongue around the head of Ruby's circumcised cock. After a few moments teasing her little sis Yang gets serious. Kissing the very tip of the dick she pushes forwards. Her lips parting as she slowly takes inch after inch of it, opening her throat to take more of it effortlessly. Blake and Weiss watch dumbfounded on either side of Yang as they realize the blonde is more than experienced as she takes Ruby's dick down to the base. Jinn decides to help those two out.

"Here, while she takes the shaft you two can still focus on her plump balls." Jinn says as she holds the back of Blake and Weiss' heads and slowly brings them towards Ruby's testicles. As a faunus Blake does have a higher sense of smell and right now she is breathing in her mistress' pheromones and sweat and she is feeling lustful in response. Opening her mouth she sucks on the scrotum as she plays with the ball in her mouth. Weiss is blushing red but finds the sight of Blake incredibly erotic as she wants to feel the same. She takes Ruby's remaining testicle into her mouth. Ruby is a panting mess as she is getting overwhelmed by the tidal wave of pleasure. Jinn moves behind Ruby and reaches around her to grab Ruby's large breasts, playing with the sensitive mounds.

This proves to be the last straw, Blake and Weiss feel her balls contract and Yang knows from instinct. The blonde pulls off the cock and pulls Blake and Weiss back too so the three of their heads are right in front of her cock.

"Alright girls open wide!" Yang says and the 3 open their mouths and stick their tongues out just in time as Ruby orgasms. Jinn reaches down and aims the cock as it twitches and cums over the slaves' faces. Thick ropes of her semen shoot out and land across their faces and into their open mouths. The sticky load spreads a pleasant warmth on their faces, the lustful stench from the seed make the girls more aroused, and the salty taste makes them only hungry for more as they try and drink down more.

Eventually the orgasm stops as the 3's face are covered in Ruby's cum. Yang eagerly drinks the cum in her mouth down, even licking around her lips to get more. Weiss had closed her eyes as she savors the feel and taste but is interrupted as she feels someone grab her shoulders. Her eyes snap open just in time to see Blake before she kisses her, their tongues dancing with each other as they bathe in the combined cum. Ruby can't help but smile at the erotic sight, seeing the 3 of them get along better than they ever had as they all share in their leader's cum. She feels proud that she was able to do this as she feels reassured about her enslavement of them.

Unsurprisingly, her cock quickly gets hard again as the energetic girl feels ready for more rounds with her slaves and her new cock.
