Miss Wildfire and Miss Lucy have a slave in a sling. His cock bound in cord and teased and edged. But he is also fitted with a gas mask making it easier for the sadistic ladies to control his breathing.

They tease, edge and deny the cock - while Miss Lucy slips in with her strap on.

The two swap places and turn it up a notch - the edge and edge him and while they've stopped, he cannot, and it leaves him stuck with a ruined orgasm.
