You reluctantly explain the marker to Olivia.

Never having exactly been Olivia’s biggest fan, you hadn’t been planning on sharing the secret of the marker with her. But it seems that your girlfriend hadn’t been thinking that way at all, and with no other choice, you spill the beans. “She’s not joking.” Pulling out the marker, you write on Stacey’s shoulder, ‘40 years old’.

As expected, your young girlfriend is suddenly an older cougar, still absolutely gorgeous, having aged like a fine wine. Olivia can’t believe what she’s seeing, and you reach over and wipe away what you wrote, turning your girlfriend back to normal. “Wow...” she says, looking from the marker to you to Stacey and back to the marker. “So while I’ve been gone, you guys have been using this for crazy kinky sex?”

Before you can say a word, Stacey jumps in again. “You bet! It’s been so amazing! It can really do anything, though nothing lasts a long time, and it can always be wiped away.” It’s clear from how Olivia is looking at the marker, she wants to try it out herself.

It’s only now that you realize that maybe Stacey telling her was actually the best outcome. After all, she was bound to find out eventually, and it was better that it happened while you had some control, rather than the chaos that could ensue from her finding out by accident.

Rolling your eyes, you tell Olivia, “I get you want to use it, but it is ours. I’m willing to share it with you too, but only so long as I’m the one holding it to write on you.”

She raises an eyebrow. “You don’t trust me, Finn?”

You have an answer ready. “Not as far as I can throw you.”

To your surprise, she isn’t offended. “I can’t blame you for that. You’re right to be cautious, that thing could be dangerous. I’ll play by your rules though, until you trust me.” You aren’t sure that day will ever come, but never say never.

Pulling out the marker, you tell her, “Okay then, I’ll write one thing on here for you, to my discretion. What did you want?”
