What does Mxtress Ava have in store today? They start to pull straps across their sub - he's certainly not running away.

As they walk around the bench, there is the first glimpse of the latex underwear.

There is a raised platform at the head of the bed, and Mxtress Ava climbs up, "I'm going to crush you," they warn while tweaking the subs nipples.

Then, the facesitting begins.

With extra height and leverage, Mxtress Ava can really push down. Smothering the subs face under their arse, under their latex underwear.

Each time is longer as the exercise in breath control is under way.

"I like it when the subs can't breath, that's the best bit"
