Give Paige some more commands before you leave

Your sister was getting annoying with her addiction to your cum, so you give her something to do with her day off while you hit the gym for the day.

"Alright, now that you've had my cum, you have to do a few things today so it doesn't make you explode still," you lie to her gullible brain. She's still sucking your cum off of her fingers but nods with an annoyed look on her face. "First, you're gonna have to borrow my VR headset and put on some videos that I'll email to you. You'll need to watch those until the end and use your best dildo to copy the actions that it tells you to." A few hours of erotic hypnosis brainwashing should help break down her mental state to be a bit more malleable, and you had a few bookmarked from some of your online fetish communities that you've been dying to find a victim for.

"The next thing you have to do is send me a video of you pleading to be my cock **** in the most degrading manner possible, butt naked and with a lot of sexy posing". A bit of **** material should shut down any resistance, just in case. And you could always just send it to her fake bitchy friends to drive them away too so you have her to yourself.

"And lastly, if you cum at all, you will immediately have to tell your mom that you need a good hard spanking". With how buff Isa was, getting her to spank Paige would be both excruciating and sexy. You'd just have to set up a command for her on the way out. "Oh, and you have to film that too, and you'll thank her for every spank".

Paige gulped down the last of the cold cum and whined, "Why does sucking your cock need so much wooork? Stupid tranny cunt, I was going to have a spa day!"

Your eye twitched for a second but you valiantly resist the urge to make her regret those words. **** is a dish best served to a brainwashed cock ****.

"Well it sucks to be you! Now get out you crazy bitch I gotta get ready for the gym," you command. Paige whines and crawls out on all fours, taking the VR headset with her. You send her a few hours worth of bimbo and **** brainwashing material to keep her occupied. It would take more than one session to really take effect, but you have to start somewhere.

Lastly you put on your cock ring and give commands to Isa and Paige. "Isa, you will spank Paige as hard as you can whenever she or I asks you to. You will do so for at least five minutes, and every time we ask you to during the same day, you will double the time you spank her. After you are done you'll 'Grow a Cock' and cum on Paige's face, tits or ass, then your cock will disappear and you will forget you had it. Paige, you will find the brainwashing to be the most arousing thing you have ever done and will cum very easily while doing so. If you cum during one of the videos you will not pause it while you get spanked, and you will not let anything else stop you from getting brainwashed since you can take the VR set wherever you go. When Isa cums on you, you cannot eat it or clean it off until you have sent me your **** audition video. Oh, and whenever your subconscious accepts a command from me through the ring, you will kiss my dick to confirm it." You feel the ring buzz, then project your cock first into Isa's home gym where she spends her mornings, and then into Paige's room. A pair of loving kisses confirms your commands.

You grab your gym bag and head out to your car.
