John took a moment to absorb the sight before him. Sarah, lying on their hotel bed, the fingers of her left hand dipping between her legs before moving up to lazily circle her clitoris. Her right hand, however, was cupping his balls, gently weighing them. Her eyes were closed as if she were asleep, but her lips currently formed the perfect seal around the head of his cock as she rolled her tongue around the sensitive tip.
He reached forward to brush a finger over her nipple and her whole body involuntarily shivered with pleasure. Because of their connection, this sent a bolt of electricity through John's cock, and he could not help but let out an involuntary moan.
Sarah's eyes flipped open, and she released his cock with an audible pop. "You better not cum as quickly as you did the last time, we've got all afternoon today," she said mockingly.
"I could say the same for you!" he replied with a smirk.
The last time in question was at a mutual friend's party, about 6 months before. Neither had known the other would be there, so bumping into each other was a genuine surprise. After the usual pleasantries and catching up on each other's lives, the conversation turned, as it always inescapably did, to flirting and discussions about earlier encounters and the one-upmanship of who was the better lover. Anyone just passing by would have just seen two friends having a friendly chat, but there was far more going on than if you stopped to look closer.
Sarah's cheeks had started to flush. Clearly the conversation was having the desired effect. John, meanwhile, could feel the familiar discomfort that he always got when his growing cock ended up trapped in his pants at the wrong angle.
John took the lead and, lifting Sarah's drink from her hand, he put it on the table with his own. He said, "I think we both need a time-out," and they walked together out of the main room with a sense of urgency whilst also trying not to look like they were off to do exactly what John was planning to do.
After opening a couple of doors, they found a bathroom and slipped inside. Door locked, they took to each other's clothes in a frenzy. Knowing that time would be short, it was just a case of loosening enough for access, no more than that.
