[Non Fiction Stories - Reluctant] Showing pix to reluctant person

I have found a new fun past time.

Threatening to show certain individuals pictures they don't want to see or the people the pictures I have pictures of to people they don't want to see.

By threatening, I don't mean being a dick about it. Just a playful way.
(still knowing it is a possibility in my head though...)

In my life I have obtained several pics of my friends, ex girlfriends and wife.

I got my ex naked in front of her brother once and my friends. So I guess this is where this stems from.

Reluctant nudity in front of willing or unwilling participants.

I will bring up to them I will post them. Some are okay with it. So I take it to the next level and ask who they don't want to be seen by. Or go through their FB page and ask them if it's okay to show certain people.

Usually ending with a "don't you dare" and a giggle.

I worked with an ex girlfriends brother recently. I really wanted to figure out a way to show her to him. But it never worked out. To my chagrin.

I wonder if any one else does anything like this. Or plays around like this.
