You react to late to have a choice

Before you have a chance to move away, the door swings open, revealing you and Karen leaning towards it. The guy stands staring at the pair of you for a moment, and it is actually you and Karen who blink first, being caught listening in. The tension is broken when he grins at the the pair of you.

“Well, I shoudn’t be surprised really, should I. If you had dared your friend to do this, you would want evidence.” And with that he steps forward, meaning you have to move out of his way to let him through. With a quick glance back he strolls towards the door and is gone, before anyone can really say anymore.

Finally you look back into the cubicle, and see for the first time Lucy, still with her skirt around her waist and bend forward over the toilet seat, hands resting on the back wall. More than that though you see her smooth pussy and the recently deposited cum running from her. It's not a view of Lucy you had ever seen before, but it does have a strange efffect on you as you view your friend after her sexual experience.

”Jesus, that was different” she lets you know. “Not the greatest sex I ever had, but definitely different. Although still feel like I want some more.”

“More, you say” you respond, a note of dare still in your voice as you consider options.
