The device is already paired to her phone

Erica's grin deepens as she pulls out her phone. "I've been doing some research on the implant. Turns out that it's remarkably easy to pair it other devices, at least if you haven't turned on secure mode yet. I'm assuming that's one of the first things you meant to do when you got home?" She was right. It took a while to do, so the doctor advised waiting until Alex was alone was in a personal space. Too late now though. Erica taps some buttons on her screen and you hear it beep. Your pussy twitches slightly. "Oops, looks like my phone is the one in control now."

You immediately begin to plead. "Erica please give me control back, I don't normally do stuff like this and I-"

"Oh you don't?" She cuts you off. "This seems like quite a rash decision to make then, roomie."

She was right. What were you thinking?! However it was too late for hindsight. "Please, please, please, Erica. I'll do your homework! I'll clean the room for the rest of the year! I'll do anything, please disconnect your phone!" Erica looks thoughtfully, and you think to yourself. What if she doesn't give it back? She's holding all the cards right now, maybe I can take it back by ****? You look at your strong roommate. Your odds aren't great, but it might be the only option.
