Note: This is part of a larger story that will involve all variations on bisexual sex. This part features an all-woman scene as well as an all-men scene. If that is not what you like, move on.
As well, while condoms are only mentioned a couple times, please assume that they're being used in all penetrative acts.
Finally, there is a bit of time switching between scenes. Some of the action is supposed to take place simultaneously and I was unsure how to convey that.
In The Previous Chapter: Harry had long known about his wife Joan's bisexuality, but he has never had the opportunity to witness her with another woman in person. This changed when Joan's newest lover Amanda asked if her husband Sam could watch. Harry and Sam watched excitedly as their wives made love to each other. Afterwards, Amanda and Sam invited the other couple to a small gathering, and Amanda let Joan know that Sam was also bisexual...
Preliminaries
When Joan brought up the Sam and Amanda's invitation, Harry was a bit surprised. The idea intrigued him, but he wasn't sure how he felt. It wasn't so much possible jealousy as feeling a need to perform.
"I wouldn't worry about that," said Joan. "Amanda said it's not really a swinger thing, just people getting together because they enjoy sex."
As Joan had predicted, Harry had no problem with the possibility of bisexual men being present. He had never explicitly expressed any interest in other men, but he never objected when Joan wanted to watch porn with bi men in it. As well, judging by his browser history he occasionally liked to look at similar porn - even without the women. At one point she asked him straight up (so to speak) if he'd ever fooled around with a guy.
"No. I've always considered the possibility, but it never came up," Harry replied. "I've always been attracted to personalities more than bodies. You just happened to be the personality I was most attracted to."
Joan didn't tell Harry that Amanda has told her that Sam was one of the bisexual men. She felt a little erotic thrill that Sam might have designs on her husband, and wanted to see how things would play out.
Amanda and Sam's place was an older three-story house overlooking the river. Previous owners had done some tasteful renovations, adding an enclosed patio and a sauna in the backyard. The party began on the patio, where the invited were encouraged to get to know each other.
Joan and Harry had been instructed to get up-to-date tests for STIs and to bring robes or towels. The invitation had another curious phrase: "think about your inhibitions and which boundaries you want to cross." Amanda and Sam seemed determined to make this sound like anything but a typical swingers' orgy.
In addition to Joan, Harry, Amanda, and Sam, there were fourteen other people. The group was not the typical array of studs and hotwives. The oldest people seemed to be in their sixties while the youngest were in their mid 30s. were still in their street clothes but it was clear that this was a wide variety of body types. Their were lawyers, teachers, and a doctor. There were two same-sex couples, two men and two women, and a single man and single woman. Joan was surprised at the last two - single women were very popular in swinging circles, but single men not so much.
Their guests were seated at assigned tables, couples broken up along gender lines. Harry was seated with Terry, a soft spoken black man, a guy in his early forties named Chris, and an older, heavyset man named Leonard. They were encouraged not to talk just about sex but anything else on their minds. Harry found out that Terry was a high school physics teacher who had recently moved from New Orleans, Chris was chef and owner of one of Harry's favourite restaurant, and Leonard was a semi-retired English professor and published poet.
Chris was tall and lanky, wiith an impressive balding head. With his aquiline nose, he reminded Harry of a Roman senator. Terry was only slightly shorter than Chris, with an athletic build and his hair in short dreadlocks. Leonard was in his 60s, broad shouldered and bearded and talked expansively with a booming voice.
Joan had been seated with Leonard's wife Sylvia, the owner of a local art gallery. Sylvia's white hair was pinned up elegantly, and she was dressed almost as if she was going to the opera. She spoke quietly, with a honeyed voice Joan found irresistible. Terry's wife Marie, a light-mocha-skinned woman with braids in her hair, was a legal aid lawyer and volunteer at her local church. Chris's wife Judy was at another table; in her place was Bridget, a blonde, full-figured hairdresser and the only single woman at the party.
After drinks and chatting Sam called the group to order.
"I want to thank you all for coming, and welcome you to our little party. We've set everything up so you can change into your robes or towels in the changing rooms just outside the sauna. Joan and I figured that would be the best way to keep track of everybody's clothes. Take your time, there should be room to fit everybody's stuff in there.
"We have a few ground rules here, the most obvious one is that consent is crucial. You don't have to verbally say 'yes' to everything, but you're all adults, you know how to behave. Any penetration on anybody other than the partner you came here with should involve latex. We know, you've all got up-to-date tests, but let's be careful, okay? There are condoms and, by special request, gloves" - this got a "whoop!" from Bridget - available in all the rooms. Which brings us to the last and most important thing: the play area.
"The living room is for everybody, and the sauna can have four people at a time, but you have to sign up for it. The master bedroom is Women Only, while the guest bedroom is Men Only. You can explore the rest of the house, but try not to fuck in the kitchen, okay?" This got a laugh from the crowd.
"So, let's have fun!"
The different couples reunited as they filed into the sauna changing rooms and emerged with robes or towels loosely covering their nude bodies. Joan and Harry met up with Amanda.
"Hey," Joan said, "I hope you don't mind us tagging along, we're both a bit nervous here." Amanda smiled an awkward smile as they walked into the house and into the living room, where the others were already matching up. Joan realized why Amanda looked at them like that when she headed towards the master bedroom. Amanda wanted to start the night out Women Only.
Joan turned to her husband.
"You okay with this, Hun?" Harry hated to admit it, but he was feeling a pang of not so much jealousy as feeling left out. He didn't have much time to think about it, however, as someone put their arms around him.
"Don't worry," said Bridget with a wide grin, "I'll keep him occupied." She led Harry by the hand to one of the couches. Sitting down, she let her robe slip revealing her ample breasts, tattooed with an elaborate pattern of symbols. As Harry sat down she gave him a big kiss.
"I'm not sure about this," Harry said, "I've never been with a stranger before."
"Well, we're not really strangers anymore, are we?" She kept kissing him and reached down to grab his cock, which had already begun to grow. She very gently stroked his swelling organ. "It looks like somebody is excited."
Harry returned the kiss, and began to play with Bridget's tits, licking and nibbling on her ruby nipples. Bridget responded with a contented sigh, then reached for a condom from a bowl by the side. She pushed Harry down so he was resting on the couch and took his cock in her mouth. Licking the sides with slow deliberation, she waited until it had reached maximum hardness and slipped the condom on. Straddling Harry, she enveloped his cock with her wet pussy.
Harry responded by continuing to massage Bridget's breasts with one hand while reaching down to manipulate her clit with the other. She really seemed to like that, meaning gently with her eyes closed. When she opened her eyes she looked around the room and squealed. She gestured to the other side of the room and told Harry to look.
On the other couch Marie was lying down, her pussy being licked and stroked by Chris. Chris's wife Judy was kissing Chris while helping her husband manipulate Marie's already swollen clit. Another figure emerged near Chris. It was Mike, one half of the male/male couple. He whispered something in Chris's ear, which got a nod from Chris. Slipping on a glove, he picked up a bottle of lube and began smearing it in Chris's ass.
Harry watched in awe. He knew there was a chance he might see man-on-man activity, but he hadn't considered Chris would be into it. As Mike put on a condom and slowly entered Chris, Harry found his own cock twitching even more in Bridget's pussy.
The scene became even more erotic as Judy climbed up onto the couch and delicately sat of Marie's face. Marie was obviously no novice, as Judy soon began groaning with ecstasy. Harry was breathing heavily as Bridget leaned over to kiss him once again.
"Nice view, isn't it?" Bridget's smile was nearly incandescent now, as sweat dripped from her face down to Harry's body. Harry felt a powerful orgasm coming on as he filled the condom. Bridget came shortly after, letting out yet another squeal. She smacked Harry on the ass and kissed him again.
"We're going to have to do this again real soon, Harry." She climbed off Harry and sat beside him on the couch, watching the show in front of them and cuddling Harry close.
Harry took in the sight on the other couch, with Mike masterfully screwing Chris's ass as the women writhed under their respective partner's oral ministrations. Chris himself was stroking his rock hard cock when Amanda came by and offered up her mouth. If Amanda was there, where was Joan? Harry gathered up his robe and got up to walk around. His cock was still deflated but already stirring, as he looked for a new partner. He briefly considered offering his cock to Judy's mouth, but he was unsure how the dynamics would work and decided to move on.
Then, looking in one of the bedrooms, he saw the sexiest thing he'd ever seen in his entire life.
2. Joan And The Ladies
When Amanda led Joan to the master bedroom, they found Cassie and Michelle (the female couple) on the bed with Judy. Cassie had brought a strap-on and was working Judy's cunt doggy-style while Michelle was licking the underside of Judy's slit. Joan took the lead, diving for Amanda's waiting muff like a thirsty man at an oasis. Amanda writhed as Joan's expert tongue did the job. After several minutes Amanda came in a gushing orgasm that drenched Joan's face. Joan got up off her knees and gave Amanda a huge kiss, letting her taste her own juices. Amanda was about to move down to return the favour when someone tapped her on the shoulder.
"May I cut in?"
