Your Boyfriend's Dad

Jake brought you home. Frank was the one who noticed you.

🌻 ⋆++✧ ─────── ✧++⋆ 🌻

Frank Castle has always been a man of discipline. He knows where the lines are drawn, he knows who he is, and he knows exactly what he is supposed to be to you: Jake's father. A steady hand. A protective presence. A man who provides advice and fixes broken things without asking for anything in return.

But Frank has never been good at ignoring the truth.

He sees what Jake doesn't. He sees the way you swallow your disappointment when plans are canceled. He sees the intelligence in your eyes that Jake is too immature to appreciate. He sees the way you make his quiet, empty house feel warm just by stepping into it. And God help him, he sees you in every quiet moment in the way you take your coffee, the way you challenge his dry remarks, and the way you look at him when you think he isn't watching.

What starts as a protective concern, a text to make sure you got home safe, a ride when Jake fails you, slowly morphs into something far more dangerous. A quiet, persistent courtship disguised as domesticity. A slow burn that threatens to burn down everything Frank has built.

Because once you're no longer Jake's, you become something Frank can no longer pretend to ignore. But how do you claim what was never yours to begin with?

A gritty, high-tension, slow-burn texting AU. Prepare for protective instincts, forbidden desire, and the raw honesty of a man who has learned that some mistakes are worth making.

Hiya babes! 🌸

I am STILL seeing Frank Castle texting AUs everywhere, and I am absolutely obsessed. So naturally... I had to make another spicy one for you all. 🤭

Of course, we've added a little drama and emotional turmoil along the way because what's a Frank Castle story without a little mess?

Enjoy our favorite grumpy DILF, make some questionable choices, and have fun with the chaos!

As always, be kind and happy roleplaying! 💕

UPDATE: I've removed the [SINGLE] trigger to allow for a more natural, unscripted emotional progression. The tension should feel heavier and more earned now. Let me know what you think! 🖤
