Light from the full moon shone in through the windows. It had been Charlotte's idea to open the curtains at night. It was her experiment with exhibitionism. Of course she also insisted the lights remain off as long as the curtains were open. As a result no one could actually see in. It was a very controlled experiment.
Brad looked at the clock; it was two in the morning on a Saturday. Charlotte was fast asleep. She had kicked off the covers and was sprawled out on the bed. Despite Brad's many requests and occasional begging, she would not sleep nude. He had managed to negotiate her down to panties and a slightly oversized tank top. The curve of her breast was visible through the arm hole of her top and was illuminated by the moonlight. Her panties had bunched up and almost looked like a thong.
Brad put his head back on the pillow. He should be tired. He was not. He was horny. Charlotte had rebuffed him when they went to bed saying that the earlier tryst in the shower was sufficient. At the time what she said made sense. Two blowjobs from Sherry and fucking Charlotte in the shower should have satisfied his desires. Now, he wasn't sure. He looked at his wife again. She was lying on her belly, her ass practically begged to be pinched. Brad rolled out of bed. He would do what he usually did when he was too horny to sleep. He would go the gym and work out. At this time of night there was usually no one there. Even if his erection did not go away, there was no one to notice it. Brad paused after taking off the shorts he had been sleeping in and looked at Charlotte one more time. Now that he was naked she looked even more tempting. He wondered if it was possible to fuck her without waking her up. Maybe if he used lots of lube and went very slowly he could pull it off. His plan was derailed when Charlotte tossed and turned, ending in a position that denied him access to her sex. Brad got dressed and slipped out.
For what had to be the hundredth time Sherry picked up her phone. She wanted to sext Brad, but he was home with his wife. Sherry had left Brad's house extremely frustrated. She had no right to be. In the hour she and Brad were together she came twice. It was unfortunate that his wife had arrived home early, but the three of them had an agreement, and Brad's wife could change the schedule at any time. Sherry had hoped that her date tonight would pick up where Brad left off, but he proved unworthy. He spent most of the evening complaining about everything. When one of her friends called to ask a random question she pretended it was an emergency and ended the date early. Sherry set the phone down on her nightstand, right next to her vibrator. She had still been quite horny when she got home, but no method of masturbation seemed to satisfy her desire for a real live hard cock. She picked up the phone for the 101st time and began playing with the apps. When she pulled up the find my friends app she noticed Brad was not at home. She began typing. Brad had just left his house and was waiting at a light. His phone buzzed, it was a text from Sherry. He wondered if she wanted a ride home from wherever her date had taken her so she did not have to do the walk of shame back to her car.
You are up late
The light turned green, but he remained stopped as he replied to the text.
Could not get back to sleep, going to the gym. How was your date?
Brad sat at the green light, waiting for a response. He did not have to wait long.
Sucked, and not in a good way. Dude was a total dud, bailed early. So horny.
Brad could not resist replying.
I'm sure you have something for that.
Almost right away the response appeared.
Nope, tried this.
A picture of Sherry's thumb and forefinger tugging on her nipple appeared on Brad's phone.
And this
Another picture appeared; this one of Sherry's hand between her legs. The angle was such that he could not see her fingers disappearing between her labia, but it was implied.
And this.
The next picture was not as subtle as the previous one. It was of a large purple vibrator between Sherry's legs. Her pussy was obscured behind the toy, but it was pretty clear what she was doing. His phone buzzed again.
Meeting you at the gym.
Brad felt his cock stir. He was a little sore from the day's activities, but Sherry's implied offer was impossible to resist.
Sherry put on the absolute minimum amount of clothing; Shorts, T-shirt, socks and shoes. Anything less and they would let her in the club. She had not been kidding with Brad. No amount of masturbation seemed to quell her desire to have him inside her. She was not sure what she would do when she got there, but she had to go.
Brad pulled into the nearly deserted parking lot. He could see the reception area of the gym. There were a couple people standing around chatting, but they appeared to be leaving. Brad turned off the ignition. The erection Sherry had inspired was still quite obvious. It was much too obvious to walk into the club with such a crowd at the front desk.
