Thanks to my editor cheer_smartie526 for all the help, and some great details that I shamelessly stole from her stories.
This story should make sense even if it is the first one you are readying. It will make more sense if you read the one before it, and a lot more sense if you start at the beginning of the series. I hope you enjoy the story.
Charlotte looked at the two glasses of water on the table, and then glanced at her watch. Sherry was late. There were a lot of things that could make Sherry late. It could be traffic. It could be an unplanned family issue. It could be work. Or it could be that Sherry was busy fucking Brad, also known as Charlotte's husband. It wouldn't be the first time Brad had made Sherry late and Charlotte had only herself to blame. Charlotte had instigated the affair between Brad and Sherry so that Brad could fulfill all his sexual desires. Originally it had been to relive her guilt over not being able to match her husband's sex drive. So far the arrangement had worked out quite well. Brad had stopped hinting he wanted sex more often, and Charlotte was more that satisfied with his performance as a husband. Much to her surprise, Brad seemed to have plenty of performance for her even if he had been with Sherry earlier in the day. He swore he wasn't getting any help from modern medicine. Brad claimed it was Charlotte's trust and understanding of his needs that provided his sexual stamina. To top it all off the time that they did spend together was more enjoyable without Brad constantly hinting that he wanted to get home and have sex. Charlotte's contemplation of her situation was interrupted by Sherry's arrival.
Sherry sat down across from Charlotte, "Sorry I'm late, I had to tie up a few loose ends and it took longer than I thought it would."
"No problem, I've been entertaining myself thinking about the soap opera my life has become."
"Is our arrangement becoming a problem?" Sherry asked.
"No, no, not at all. I guess soap opera was the wrong way to say it. It's working out quite well. It's a bit unusual."
"And Brad is performing to your satisfaction?" Sherry inquired.
"Absolutely, although sometimes it's a bit weird knowing he was with you only hours before..."
"I know the feeling. There have been times that it has only been thirty minutes from us having a threesome," Sherry said with a laugh.
"I don't know how he does it at his age. I'm glad you are there to deal with all of his, uh, energy. Brad doesn't understand there can be too much of a good thing," Charlotte said.
"I think he just paces himself. If he spends extra time on kissing and licking then I know he has been with you," Sherry said.
"The tip off for me is he smells clean, like he just got out of the shower," Charlotte replied, "although now that you mention it he does seem a bit less frantic."
It occurred to Charlotte that she felt a bit relieved now that Brad was getting all the sex he wanted. Sometimes she felt a bit of guilt when she declined his advances. He always respected her desires, but she wished she had the energy to fulfill his longings. Having Sherry as a second shift was working out quite well for everyone involved.
Sherry nodded. The slight smell of soap used to be a tip off for her as well, but she had asked Brad to stop showering before coming to see her. The eau de Charlotte on him made their arrangement seem more exciting.
"So are you still at two out of three?" Charlotte asked, feeling like she was gossiping.
"Yes, I'm not ready to give Brad the hat trick. I'm still thinking about it." Sherry answered. The third item was letting Brad fuck her in the ass. Sherry wondered if Brad had told Charlotte about the conditions Sherry had placed on that item; but then again, she suspected that Brad didn't tell Charlotte anything about his extramarital affairs.
"I don't blame you," Charlotte commented.
"How about you, any thoughts of working your way through the list?" Sherry asked.
"Well, number one is out. My tits are not going to get any bigger. So he will always want you for that. Brad won't admit it, but I think he has a bit of a big breast fetish," Charlotte replied
"I would say he has a breast fetish, I don't know how much size has to do with it," Sherry said.
"I guess you are right, he's certainly not lost interest in the twins," Charlotte said with a laugh.
"Who calls your breasts the twins?" Sherry asked.
"I do, Brad sticks with anatomical terms, you know, breasts, tits, boobs and so on." Charlotte answered.
Sherry laughed as well, then continued her inquisition, "What about the rest of the list?"
"I have to admit the second one is actually starting to intrigue me. I don't think I could make Brad do for me what he did for you," Charlotte replied, blushing at the thought of spitting Brad's cum back into his mouth.
"I think deep down you want to swallow. I read somewhere that men see it as a sign you have accepted them completely. It may be a story someone made up to get more oral sex, but I guess it makes sense," Sherry said. She knew if Brad stopped giving Charlotte a choice his wife would swallow his cum and be happy about it. Sherry also knew that Brad would let Charlotte snowball him; there were very few things that would cause Brad to say no to his wife. She had told Brad the same thing ten minutes earlier, right before she left him tied up. He was about fifteen floors above her with nothing to do but think about getting Charlotte to swallow his cum.
"I don't know about that," Charlotte replied.
A guilty grin spread across Sherry's face, "Then I have a confession."
"What?"
"I may have led your husband to believe...well....," Sherry began to giggle.
"Out with it!" Charlotte insisted.
"That you wanted him to do it," Sherry finally managed to explain.
"I'm not sure I'm going to allow that to happen."
"What if you didn't have a choice?" Sherry asked.
Charlotte put her hand her to her chest, "Whatever do you mean, dear friend?"
"What if you were tied up?" Sherry inquired
"Then I suppose I would just have to take it," Charlotte murmured. Brad had tied her up before, but the situation not flowed the way she expected it to. Perhaps it was time to try again. The thought of being powerless to stop Brad from fucking her face and filling her mouth with cum was surprisingly arousing.
Sherry pulled her phone out and tapped on the screen a few times, "Your husband is on his way to join you. I hope you have a happy Valentine's Day."
"He texted you and not me?" Charlotte replied.
"Crap, I probably wasn't supposed to tell you. Try to act surprised when he shows up."
"Did you put him up to this?" Charlotte queried.
