Catching her breath, Sarah's eyes fixed on John's. A level of determination and mischief passed across them as she started to stroke John's aching cock with such vigour that his legs almost buckled at the intensity of her actions. Sarah knew John's body well enough to feel the signs of his impending orgasm and teasingly stopped stroking just long enough to get a questioning and pleading look from John before stroking him faster and harder than before. Not wanting to make a mess, Sarah reached for a towel just as his body tensed and his cocked jumped in her hands. She kept stroking as jet after jet of cum hit the towel. John's body shook with pleasure. The force and intensity of his orgasm always managed to take John by surprise. He uttered the only words spoken since they locked the door: "Fuck!" under his breath as his orgasm subsided.
They both stood, catching their breath, eyes locked, and bodies occasionally twitching with the aftershocks of orgasm for what seemed like an age. It was Sarah who broke the deadlock by pushing John playfully down onto the toilet behind him.
"You wait here," she said as she re-arranged her clothing and checked herself in the mirror. "Give me 5 minutes and then you can come out. That way, we shouldn't look too suspicious." With that, she unlocked the door, checked the coast was clear, and slipped out, closing the door behind her.
John took a moment to gather himself. Sarah had left the bathroom looking as if nothing had happened, but John caught a glimpse at himself in the mirror to see a red-faced and dishevelled-looking man staring back at him. How was it possible that Sarah managed to appear so fresh, yet he looked like he had fallen backwards through a hedge? John chuckled to himself as he tucked his shirt back in and tried to look as presentable as he possible, considering what had just happened.
He took a handful of chilly water from the sink, splashed his face, and then ran his fingers through his hair. "Close enough to normal," he thought as he left the bathroom and headed back to the party. He figured it might be best to avoid Sarah for a while just in case there was anyone who had noticed them together, but that didn't matter as he couldn't see her anywhere.
John checked his watch. It couldn't have been more than 15 minutes since they first locked the bathroom door behind them, but to John it seemed like hours.
A hand on his shoulder brought John out of his daze. "Looks like you need a drink!" said Steve, the party host. "Not like you to be standing around without one!" as he placed a bottle of beer firmly in John's hand. "I need you to meet Dave as he's looking to join the company, and I said that you'd be able to fill him in about the job." Steve started to guide John through the groups of people to where Dave was chatting away to other people from the office.
John furtively looked round the room, hoping to catch sight of Sarah, but he could not see her anywhere. She must have made her excuses and left. "Oh well," he thought. "Until next time, then..."
