"I don't understand"
Mo looked up from her computer.
"It is simple. She wants to watch us having sex. Maybe with other people as well."
"Why, I don't understand."
Tom was locked into old fashioned logic. He could not see anything different.
Mo did see and was already considering who she could ask.
The woman hadn't said just men and women.
She decided the first time might be better with Steve. He was always looking to shag her.
"Hello, I am Mo, this is Steve. My boyfriend is not here. He doesn't get it."
"I am Aria. I understand his problem, there is a proper name for it which I think is voyeurism."
She ushered them into her house. She had a bed on the ground floor, where most people would have sofas or chairs. She had a folding chair. Mo guessed that she sat on that.
"Do you want to touch us or join in?"
"No, watching is sufficient, thank you."
They stood and looked at each other.
"Would you like to take your clothes off?"
Mo looked at Steve. This wasn't as straightforward as she had thought. When she saw the advert, it all seemed so simple, now - not so much.
Steve was undressing, for some reason he turned away.
Oh my, he was floppy, no erection. That must be a first.
She stripped naked. Her nipples were hard, she was damp. She was loving this.
"Can I help you?"
She looked down and he followed her eyes.
Definitely "brewers droop" with alcohol.
He didn't speak and just started wanking.
"Mo, why don't you play with yourself while Steve catches up?"
Mo had forgotten Aria was there.
"OK."
She rubbed her nipples first, then moved one hand to her clit.
She stroked and Aria and Steve watched.
He started getting hard. She smiled at Aria, that was a clever ploy, must have been here before.
Steve was hard, not rock hard but more up than down.
Aria was watching both of them. Mo could see that Aria had stiff nips, so she was getting turned on as well.
"Are you ready?"
Steve nodded. He still had not spoken a word. Mo would take the piss out of him later.
