TIFU by hiding a marzipan-filled condom in the wall as a teenager, and now my family thinks my dad put it there

This has been bugging a little bit for years now and I feel like I gotta get it off my chest. So when I was a teenager, our house was getting renovated, and I was helping out with putting up new panels on the walls. And for whatever reason, I came up with this dumb prank.

I took a double condom (teenage curiosity), and instead of doing anything normal with them, I filled they with marzipan.. Still not sure why, but I thought it was funny as hell at the time. I tied it up, now looking like a mazipan dildo, and before I sealed up the wall, I put it on top of a stud inside together with a thong (pantie that I had collected from a homeparty). Then I covered the wall up, and I just kinda forgot about it.

Fast forward like 20 years, my brother buys the house from my parents and decides to do some renovations too. He rips down that same wall and guess what? He finds the old, crusty marzipan condom and a red thong!

Now, here’s where it gets really awkward. No one has any idea it was me, and everyone in the family thinks it was my dad who put it there during the original renovation. My brother and our sisters have had full-on conversations trying to figure out why he would’ve put a condom in the wall. Like, was it a weird joke? Some creepy keepsake? They even speculated if maybe it was used for something… ?

For the last three years, I’ve just kept my mouth shut while they’ve tried to solve this mystery. It’s come up at family dinners and gatherins, and always I’m sitting there knowing the whole time that it was just my stupid teenage self trying to be funny.

I kinda feel bad for letting it go on this long, especially since our dad is not with us anymore, but I also can’t help but laugh every time they bring it up. Maybe one day I’ll fess up, but for now, it’s too funny to watch them try to figure it out. But it also is a fuck up. Because I have kept it a secret for 3 years now. Why would I tell the truth now? That would make me an idiot for putting this dark story on our dad.

TL;DR: I put a marzipan-filled condom and a thong in the wall as a teenager, and 20 years later, my family found it and thinks my dad did it. I haven’t told them it was me, and it’s been 3 years of them trying to solve the mystery. Now I feel like I fucked up.
