Been planning this for a while now
I'm going to completely cover her in as much mess as I can
She has no idea what's coming
And I will blind fold her before I lead her into the bathroom
Shower gel
Shaving foam
and a bucket of red gunge should do the trick

Will post some pics later

I do hope you've agreed beforehand that this sort of surprise is okay, and that she's okay with pictures being posted, because if the answer to either of those questions is 'no', then this is not okay in any way.

Oh don't worry she knows what I like
We have discussed it many times and it her who is pushing it

Would never make her do anything she doesn't want to.

Then in that case, enjoy yourselves! And each other!

Well thank you
We will.

Well that was amazing
She absolutely loved it
