Desc: Erotic Sex Story: Now that Lisa has joined Sarah and Greg in marriage, the three lovers must learn to live together in harmony.

Previously in the Sarah and Greg Series:

About a year after Greg and Sarah moved in together, they had a day of living out some sexual fantasies. ("Sarah and Greg's Day of Exploration") During the course of the day, they met Sam and Christina (Chris), who lived several floors above Sarah and Greg. This was the beginning of friendship which has resulted in the occasional dinner or social outing with them over the following almost-two years. While on their honeymoon in Hawaii, Sarah and Greg meet Lisa ("The Honeymoon of Sarah and Greg, Days 2-3"). The three bonded and their love grew over the next year, highlighted by Lisa visiting. During one of the visits, Lisa confessed that she is unable to have children, since she and husband, Mark, tried and were unable, and he was tested and he was not the problem. On the third visit, Lisa tells Sarah and Greg that she and Mark are getting divorced; they ask her to move in with them, and she agrees. ("Lisa Visits Sarah and Greg") She wraps up loose ends in Hawaii and finally moves in with Sarah and Greg creating a marriage triad. ("Lisa Moves In with Sarah and Greg")

THE ADJUSTMENT PERIOD

Sarah, Lisa, and Greg managed a relatively smooth transition. There were some minor issues, such leaving the top on or off the toothpaste, the order of using the bathroom in the morning, or who sleeps in the middle, but they all knew things like this would come up. Most of the dinners together for the first few months were spent discussing these issues and working out a solution. Not every plan worked, but they revamped it as they went. After a while, the conversations around issues became shorter and then less often and then the exception more than the rule. So after five months, the three of them were living together in harmony as a happily married triad, but like all families, there was the occasional problem which needed to be addressed. However, the pattern had been set, and they all knew that any of them could bring up a topic at any time, and all three would talk about it.

One topic which both Sarah and Greg really had little experience with was a woman's period. Lisa assured them that it was not a huge deal for her, other than her periods were very irregular. No PMS, no cramps, no bloating,... – none of the stereotyped woman's problems associated with them. Other than Lisa's not wanting to have sex (usually) for a few days each four to seven weeks, there was nothing to worry about; they would deal with it as things came up.

SARAH, LISA, AND GREG HAVE DINNER WITH CHRIS AND SAM

Six months after Lisa "married" (moved in with) Sarah and Greg, Sam ran into Greg by the apartment mail boxes. When he saw Greg, he said, "Oh, I've been meaning to invite you and Sarah up for dinner some time."

"That sounds good."

"How about Friday night?"

Greg thought for a moment and replied, "Friday sounds good." Sam smiled. Greg then remembered Lisa and added, "Oh, before I forget, Lisa, ... a dear friend of ours, will be joining us, if that's okay."

"Not a problem. Chris and I will see the three of you, then, on Friday around... 6 or so?"

"Sounds like a date," Greg responded.

When he got to the apartment, he told Sarah and Lisa immediately before he forgot. Sarah was excited, and said to Lisa, "Sam and Chris – actually 'Christina' – are good friends. On the day Greg and I had sex four times, they saw us twice, but acted as lookouts..."

"Mostly," Greg interjected.

"They were really cool with the whole thing. We ended up having dinner with them that night." She thought for a moment, "And if I recall correctly, Greg proposed to me on the elevator on the way back down to here after dinner."

Greg smiled and nodded, "It was like it was yesterday, ... or a lifetime ago." Sarah nodded.

"So," Lisa began, "they know about you?"

Sarah replied, "Actually, they don't. They never saw our... 'naughty bits'. We weren't in any position a regular couple wouldn't be in." She thought for a moment, laughed, and mused aloud, "Is there any position which we would be in which would be outside a regular couple's position?" Greg was about to mention if he were bent over and she were standing behind him with her cock in his ass, but then he remembered that women sometimes were strap-ons.

Ignoring Sarah's question, Lisa looked at her two spouses and asked, "When we go up there, what am I?"

Greg felt a little like Peter in his denial of Lisa. "Oh, sorry. I wasn't sure how to explain us, so called you 'a dear friend of ours'."

Lisa accepted the reality of it, but felt sad that her marriage was hidden. She brought this up as an issue, and the three talked about it, and agreed that for now, they needed to keep the full relationship a secret. None of them were happy with feeling like they had to keep it secret, but it was where they were at that point in the relationship.

That Friday evening, the three of them went up to Christina and Sam's place. Sarah knocked on the door, and Chris greeted them happily a moment later. Introductions were made, and soon all five of them were sitting in the living room. Sarah sat on the couch between her spouses. Lisa tried desperately not to lean on Sarah, since she was trying to act as a friend of the family and not a lover.

The conversation was light and pleasant. At one point, Sam left to see how dinner was progressing in the kitchen. While he was gone, Lisa asked, "So Chris, how did you and Sam meet Sarah and Greg." Chris looked at Sarah to get some indication of how much detail she should give. Sarah, for her own amusement, did not give Chris any help.

"Well, we happened to run into them a few times over the course of one particular day which led to our inviting them to dinner."

Sarah laughed, "I was wondering, Chris, how you were going to handle it."

Greg chimed in, "They first saw us when we were having sex in the elevator, and then later when we were having sex in the park."

Chris started laughing. Sam walked back in and asked, "What's so funny?"

Lisa answered, "Sarah and Greg were having fun with your wife to see how much she would say about how the four of you met."

Sam replied, "I assumed that you already knew?"

Lisa answered, "I didn't know that you met on that day, but I did know about the things they did that day." Then she remembered that she had been told. She put her head down in embarrassment and confessed, "Sorry. Now I remember that Sarah told me. I am sorry; I didn't mean to set you up like that."

Chris laughed, "No harm. Don't worry about it."

"Ah, then you know about the kiss Greg and I shared." Sam winked at Greg jokingly and then returned to the kitchen.

Lisa's jaw dropped open, "Really!" She turned to Greg. "You never told me about your making out with the your upstairs neighbor."

Greg defended himself, slightly, with "Sarah and I weren't even engaged yet."

"By only a few minutes," Sarah added.

Sam returned as Greg offered a better explanation, "It was part of the experience of the day."

Sam tossed in, "I would kiss you again, because after last time, Chris indeed made me forget all about the kiss. I didn't really walk well the next day."

Chris looked at her husband, "You don't need to kiss Greg to have that happen again ... if I'm in the mood." Sam looked at her hopefully, and she smiled an enigmatic smile and returned her attention to the guests.

Sam then asked, "Lisa, how did you meet these two?"

Sarah started laughing, and Greg just smiled. Lisa just openly asked, "Greg, Sarah, how much do you want me to tell?"

"I'm fine with whatever you wish to tell," Greg said.

Then Sarah realized that 'whatever' might be too much. She leaned over and whispered into Lisa's ear, "Just leave out the part about my anatomy." Lisa nodded and smiled to assure her.

"We met on their honeymoon in Hawaii. My husband at the time and I were attending a swinger's party when these two showed up wanting to have sex in front of strangers. Yada, yada, yada, we became friends."

Sam commented, "Those are probably interesting 'yada's"

"Oh, they are," Greg added, "but you will just need to use you imagination ... or remember the two times you watched us that day we met."

Five minutes later, a timer went off, and Sam announced that dinner was ready.

The five had a terrific dinner as they talked about non-sex topics. Lisa was charming as usual, and near the end of dinner, Chris asked, "Lisa, do you still live in Hawaii?"

"No, after I got divorced, I wanted a new start. So I relocated to here. Although the weather is less paradise here, the friends are better."

"Ah so you are here permanently? Where are you living?"

Lisa paused to consider her wording. Greg interjected, "She's staying with us for now."

Sam put the pieces together and conjectured, "I assume that 'for now' means 'for the next fifty years, if need be'"

"Sam!" Chris said quickly.

Lisa looked awkward, and Sarah stepped in, "You're probably thinking about the bigger bed we ordered. Aren't you?"

Sam answered, "Yep, and the other clues from this evening."

Sarah then put her arm around Lisa and kissed her on the cheek. Greg stood up and walked over between the two women and kissed them both on the cheek. Sarah then confirmed Sam's conjecture, "Lisa is indeed a part of our marriage."

Chris and Sam were both non-judgmental. Chris spoke first, "Wow. I don't think I could do it. It's hard enough being in love with one person. Two would add a whole new dynamic which could so easily spin out of control."
