"What were you and Mark talking about?" Bill asked.
"Nothing much, why?" Cheryl answered.
"I don't know, he just had this look on his face," Bill replied.
They had just gotten home from a neighborhood party and were getting ready for bed. "What do you mean?" Cheryl asked as she pulled back the covers and slid into bed next to her husband.
"An interested look," he said.
Cheryl reached out to turn off the light. "We were talking about plants and gardening. He wants to re- do his front gardens this year."
"Not that kind of interested," Bill continued suggestively
Cheryl picked up the tone of his voice and laughed softly. "Oh sure, Mark is that kind of interested in me."
Mark lived a few houses down the street. He was divorced and in his early forties, which made him a few years younger than Bill and Cheryl.
"I swear, Hon, he looked like he was going to kiss you."
Cheryl giggled again. "Oh please."
"You looked like you wouldn't have minded, either," Bill went on.
"Bill!"
"What? I was watching you two, and in my mind I could see him leaning forward and kissing you. Your eyes were so bright, I could practically see your lips parting and your body pressing forward against his," he kept on.
Cheryl turned to face him in the darkness. "Bill, we were just talking about gardening."
Bill was ready to let the matter rest, and leaned over to kiss his wife goodnight. He was surprised when she kissed him back with some ardor. Usually at this hour she was too tired and wanted to go right to sleep. Bill continued with the kiss and let his hand wander up his wife's thigh under her night gown. Her legs parted and he cupped her panty covered mound. She moaned softly into his mouth. He slipped his fingers inside the legs of her panties and traced her labia, finding it already quite moist as she moved closer to him. He began to manually stimulate his wife's clit while he kissed her, feeling it get firmer beneath his finger. Her hips started to move and her body started to shudder in what seemed like record time. Bill was amazed at how quickly his wife had reached her first orgasm.
He reached up and started to peel Cheryl's panties off, with her lifting her hips to help him. He stripped off his own pajamas and was immediately between her open legs. She was unusually eager and helped pull him into her. His swollen dick slid easily into her waiting wetness and she cried out from his sudden deep thrust. Her hands went to his back and then down to his ass, pulling him hard against her.
From there is it seemed like an urgent race, each of them spurred on by the other and by some outside erotic force. Bill was caught by his wife's surprising lust and exploded first. He kept thrusting hard and fast as his balls exploded, spurting his hot seed into Cheryl's juicy cunt. The explosive throbbing of his cock carried Cheryl right over the edge and they clung to each other as joy swept through their bodies.
*************
A few nights later Cheryl came home to find the house empty. She called out for Bill or the kids and finally she heard Bill respond from the back yard. She went out the back door to find Bill and Mark at opposite ends of the hot tub, each with a beer in his hand, laughing about something.
"What are you two doing?"
"Mark came by and we started talking about the hot tub, so I suggested we have a beer and try it out," Bill answered. "Why don't you join us?"
"I don't think so," Cheryl answered. "Where are the kids?"
"They are all out for the night, they won't be home until after 11," Bill replied.
"Come on, have a drink with us," Mark smiled at Cheryl. "After all you were the one who was telling me how great the hot tub is."
Cheryl gave Bill a quick glance, because she hadn't mentioned this part of her conversation with Mark the other night, but Bill didn't seem to notice. Cheryl went into the house and came out with a glass of wine and pulled a chair over next to the hot tub and sat down. Both of the men frowned at her.
"That isn't exactly what we had in mind," Mark said as she sat down.
"I don't feel like putting a bathing suit on," Cheryl answered softly as she took a sip of her wine.
"Who said anything about a bathing suit?" Bill laughed.
At that Cheryl peered over the edge of the hot tub. It was hard to see anything through the swirling bubbles, but she definitely did not see any tell tale flashes of color. "Please tell me you guys aren't naked in there!"
"Okay, we won't tell you," Bill laughed some more. "Hey, you were the one who was telling me how good it felt to sit in here nude," Mark responded softly, trying to catch her eye.
"Yeah!" Bill said quickly, "how come you don't tell me how much you like being in the hot tub nude?"
"Well, I..." Cheryl stammered.
Bill climbed out of the hot tub. "Bill!" Cheryl exclaimed as his naked form emerged from the foaming water. He walked right over to her and started unbuttoning her blouse.
"You told Mark how much you liked this, I think you should show him," Bill answered evenly as he continued to undress his wife in front of his neighbor.
"Oh all right, get back in the hot tub!" Cheryl said, pushing his hands away.
Bill turned to get back in and Cheryl took her clothes off as quickly as possible, but both men were eying her intently as she slipped her panties down her legs. As soon as they were off the she clambered over the edge and submerged herself in the swirling heat. She let out an audible sigh as the warm wetness enveloped her in its continuous massage.
She had left her wine glass on the table and Mark stood up as he offered to get it for her. He was about six feet tall and in very good shape, lean but muscular with a flat stomach that showed a hint of the six pack that was undoubtedly there when he was younger. Cheryl watched him in spite of herself and Bill followed her eyes as she checked Mark out. When Mark handed her glass to her, his package was right at eye level and Cheryl blushed deeply as she stared at his semi erect cock. Mark sat back down on the far side of the hot tub, letting his body sink back out of sight.
