Turn up the Dial Even More

Jenny continued rubbing her clit while she saw the arousing sight on her screen. Her previously naive and innocent sister was taking a big 9 inch cock up her ass while cum dripped down her face and obscenities about loving anal flew out of her mouth. Jenny felt a bit bad for jilling off to her sister and her boyfriend, but she just couldn't help it.

As the love birds continued their aggressive sex, Jenny felt a need to turn things up a notch. Sure, the anal sex, the "sir" and "pet" talk, the facials, and all that was hot, but Jenny thought she could go further. She was also curious how the computer program would handle commands on the fly that worked retroactively.

First she wanted to turn up Grace's submissiveness even more. It was already at 70%, but she wanted to see what Grace would act like if she did more. Jenny turned Grace's submissiveness up to 95%. This prompted a new box to pop up asking who Grace was submissive to. Keith was already filled in, but Jenny decided to add in her own name as well.

Just for equal measure she pulled up Keith's own profile and turned his domination level up to 95%. Oddly there was no option to select who he was dominant towards. Just as she was about to go back to Grace's profile, Jenny noticed a bolded note under Keith's fetishes: Strong Fetish for Asian Women. Jenny scoffed, realizing her sister's boyfriend was just another white guy with yellow fever. Though Jenny admitted she was being hypocritical, given she herself was almost exclusively attracted to Asian women, though being Asian herself had to mean something, right?

Shrugging, Jenny went back to grace's profile and scrolled the page to find further things to change. She hovered over the fetish tab, which expanded into a long list of options that seemed endless. The usual suspects were at the top such as cum, feet, bondage, rough sex, analplay, and spanking. Jenny laughed, seeing that only bondage, rough sex, and spanking were check for Grace. This was despite the fact that her sister was currently having a large dick rammed into her ass while she had a face full of cum. Based on how vocal Grace was you would think she was loving the anal, but Jenny guessed it was her sister's submissive nature and love of rough-sex overriding things.

Jenny hovered over the various fetish options and saw they expanded further. The bondage one for example had subcategories you could select, such as latex, rope bondage, handcuffs, restraints, ball-gags, and many more. Some of these were checked, but others weren't. The cum category was the same with options ranging from creampies and cumshots, to bukkakes and gokkun. Jenny wasn't even sure what that last one meant, instead thinking of that Dragonball Z character. Jenny moved on, thinking that she could test those out later.

She saw there were similar options below the submissive percentage slider she used earlier. The main one was labeled "Submissive Type." Jenny clicked the tab and opened up tons of different options, some of which she wasn't even sure what they meant: Petplay, Latex doll, BDSM, Free-use, toilet, cuckquean, ****, raceplay, concubine, objectification, exhibitionist, forniphilia. Jenny was pretty sure she knew what petplay and exhibitionist would do, but she had never heard of Forniphilia. Unlike the fetishes, this was exactly what she was looking for. A catchall category where she could test out different options for her sister. She wondered which one (or ones) she should pick for her slutty sister. There was even an option to fill one in if she wanted to get creative.
