Being walked on a leash fantasy..

So my bf/dom and I practice petplay, sexually and non-sexually. We recently got a leash (before we just used ribbon and belts) and I've been starting to fantasize about him walking me outside.

Like in the middle of the night, if he put the leash on my collar and held it in one hand and held my hand with the other, and we walked to the park by our apartment. If I got excited or walked too far away from him he could just pull me back with the leash.

I really want to try this.

Does anyone else like leashes? Whats your experiences?
