Rio creates a futa bull to be his sub

Rio was a greedy man. His dick was small, but his ambitions were big. Ever since he moved out, he hasn't let his fetishes lie dormant anymore, filling his apartment with pornography and wishing upon a magic star until the Family Maker came into his lap, and he knew what chance he was given.

Rio loved futas and, if possible, wanted a futa wife to serve him, but he wanted the apex of futas: the picture-perfect futa dom, not a sub.

Rio named this creation Domina. She was the typical depiction of an ice queen or ice witch. She had fair skin, blue eyes, silver-white hair with blue hair under those top layers, white fingernails, smooth skin, no hair below the eyebrows, no blemishes, a body unaffected by freezing temps and always cold to others when touched in the heat or chill, and leotard-esque attire that didn't fit a snowy setting. Taking this further, Rio made sure Domina's chest was bountiful, literally grabbing two enormous watermelons as he decided how big he wanted her tits to be, balancing it out with a nice ass that wasn't overly sized so the hips didn't seem out of place, but were still big enough that it made a man's mouth water as it covertly thickened to make a perfect pair of thighs. Rio then made her waist slightly narrow, but still meaty enough to carry all that weight and make her seem strong and firm. Then, to top it all off, Rio went to the strength setting and started upping that number. As he did, he saw her elegant yet simple style show several bulges as her biceps grew subtly with power, doing the same to her gut as she got a six-pack and muscle-mommy thick-shaker thighs. She was still graceful and sublime, but going naked would only elevate her form as her tits defied gravity, staying up like giant balloons, the inverted and big nipples adding something adorable about her as she towered over others at a whopping 7ft, ensuring these gigantic proportions were somewhat mitigated by her monstrous height. They weren't really, because even with all her power and strength that could let her crush a skull with one hand, her ass still jiggled, her breasts still swayed, and her tongue still flopped out with its big size that could let her lick your entire face if she simply brought it out. All that was left was to give her the most important touch: a girthy dick. This dick was massive, as thick as a tree trunk and reaching 20 inches while flaccid. When not erect, her dick was like a big, medieval coin pouch stuffed in her crotch, the leotard only covering half of her thick cheeks as the bulge somehow stayed neatly tucked in her leotard. When brought out, it was like a weight was lifted, and it flops out gloriously, growing as big as Domina would need, even big enough to fuck an elephant if she really tried.

As for her personality, he made her confident, certain, smart, horny, honest yet restrained, and sly. When creating Domina, Rio made sure to specify the parameters of their relationship. How Domina could corner and seduce any woman, but was submissive to Rio's desires in the bedroom, completely captivated by his entire existence, happy and elated to do whatever he wanted, acting like a schoolgirl with him, acting like the dominant futa bull to everyone else. This way, Rio wouldn't turn around to find Domina shoving her titanic dick in his ass, likely killing him and ruining a perfect pair of pants. Rio saw a lot of futa porn, so he didn't want to become some brain-dead cocksleeve, so he added these precautions so that he could fuck this hot babe while sitting in her arms as she treated him like her gentle prince.

Moving on to her existence: she's rich. Richer than rich. Part of the only 3000-year-old family lineage with a clearly recorded history that has risen to the 8th richest group in the world through revolutionary actions in agriculture, science, market assumptions, investments, buying partial or complete ownership, etc. Clean shit that didn't make them oil barons or some evil crap like that.

As an added note, her pussy is unbearably tight because it's rarely used, but when it is, it's well lubricated by her juices, and her ass is always clean; poo just doesn't stick to her anus.

All that was left was to add the relation to Rio.
