You are taken aback.

Even though this is a typical mind game from Fiona, the question takes you aback. "What the fuck am I doing?" You think to yourself as you snap out of it just in time to maneuver your hand from her ass to push her and and your cock which it was gripping down as she attempted to impale herself on it. The **** on her thrust is uncomfortable but as her pussy lands at the root of your dick you feel how wet she is. You know you aren't out of trouble yet. Without skipping a beat she peppers your neck with kisses and licks as she fights with your hand trying to **** hers off your dick. The kisses feel amazing but as they start to get slowly more forceful you know she is attempting to mark you. As for your engorged cock, the battle there is at her advantage due to the awkward position she has you slumped in the back of the changing room. You need to choose where to focus your efforts in order to save your engagement.
