Weeks had passed since Anne and Pam played in the hot tub and bought Pam's sex toys. The two talked on the phone frequently, Pam filling Anne in on how she was driving Bill crazy with the role playing. The couple had also had another session with their friends, which went great, and Pam had coaxed out of Bill that he really did want to see her with a group of men. It was the perfect conversation for Anne to tell Pam about a swingers party that was coming up in a couple of weeks.
"Sis, that sounds exciting, and nasty." Pam said. "Should I tell Bill that you and Karl will be there?"
"No, let's surprise him." Anne replied.
The girls set the plan in motion. The party was a costume affair, so attendees could dress to their concealment desire level, with some wearing full body and face coverings except for the erotic parts of the body, and others not caring about others knowing who they were, but costumed up to a point.
Pam began shopping and decided to wear a sexy princess outfit that had a mask that covered most of her face, so Karl wouldn't know immediately it was her. She decided to break the news of the party to Bill while wearing the costume, so she texted him at work, telling him to be ready for a surprise when he arrived home.
Bill walked in from the garage to find his wife on her knees, in a nasty princess outfit, looking up at him. She didn't say a word, unzipping his pants and pulling out an already hardening cock. She slurped and licked, taking as much as she could in her mouth, and after a few minutes, she broke away from sucking and looked up at her husband.
"There's a swingers costume party one of the girls told me about. Do you want to see your wife like this? On her knees? Sucking cocks?" She asked in a "princess girl" voice. Then she went back to sucking.
"Fuck, yes!" Was all Bill could muster, getting close to orgasm. He heard a dull humming sound, and realized that Pam had her double dildo in her pussy and her ass. She was shaking now, approaching her own orgasm while getting her man close.
"I'll suck them," She moaned. "And their wife's can suck you! Then you can cum on their faces as their husbands and boyfriends cum on mine!" With that, she deep throated Bill's cock and then jacked him furiously as she sucked and licked just below the head. The vibrators were doing their job, and brought her to a crescendo right as her husband began to unload. His first shot hit her in the back of her throat, as she pulled away, allowing the next five strings of cum to splash onto her mask, lips and finally on her exposed breasts. She ended by slowly, sensually, sucking Bill's spent cock, squeezing every drop onto her tongue.
"What the fuck!?" Bill finally sighed as he came down from his orgasmic high.
"Well, I just thought you'd agree to the party if you were properly motivated." Pam replied, with a sly little grin.
They spent the next week getting Bill's costume ready. He was going to go as the joker, with a crotchless, tight fitting uniform and half mask.
==============Anne and Karl================
Anne and Karl were all set for the party. Anne was going as a cat, with the crotchless cat outfit, that also exposed her beautiful breasts, and a half mask that hid most of her face. Karl was going to be decked out in a batman costume that hid most of his face, and was also totally crotchless.
=============Julie==============
Julie had been asked to attend through the couple putting on the party, who were at the Karl and Anne party that Julie attended. Most of the people from that party would be at this one, and Julie was looking forward to getting re-acquainted with those cocks and pussies. She was going to dress as batgirl, with a crotchless, backless, body outfit that exposed her perky breasts, and a cute pull over mask that hid everything except her mouth and eyes, for which she wore cat contacts.
Julie had no idea what lay in store for her, her Aunt and Uncle, and her Mom and Step-Dad.
=========When Worlds Collide=========
Anne and Pam talked about the timing of the party. The men had no idea the other couple would be there, and the girls wanted it to be a surprise. They agreed that Pam and Bill should arrive first, so they could ease into the event and have a few drinks to loosen up Bill. Anne and Karl would arrive about an hour later and see how everything was going first. If Bill was freaking out, they could call off their rendezvous and go their separate ways without Bill ever knowing. Anne told Karl the plan and he agreed. None of them knew that there was a wildcard named Julie about to be thrown into the mix!
The day of the party, Pam was nervous, and she could tell that Bill was too. As they got dressed, Pam came over to Bill, and asked him if he was OK with what they were going to do? She looked up at him with her sexy outfit and mask on, while slowly rubbing his crotch, which was covered by a flap, held in place with Velcro.
"Are you sure honey?" Pam asked in her innocent voice. She was shocked by the response.
"I'm sure I want to see you being used by as many men as you want, you little slut." Bill replied as he snuck a finger into his wife's already wet pussy. "Are you gonna be OK watching me stuff my cock into other woman's pussies?"
"Yes, honey, I want to see you fucking them all!" Pam replied, nearing orgasm and pulling off Bill's finger before she came.
They arrived about 8:00 PM and the party was almost in full swing. There were about fifty people there already with an expected total of about sixty five people. Pam and Bill were greeted at the door by the host, John, a handsome guy from what they could tell behind his prince outfit, with a nice bulge in his "pouch". John directed them to the main room where food and drink were plentiful.
Walking up to the bar, they noticed a handsome, costume less black bartender, who was totally naked and sporting a sizable cock. They got their drinks and started walking around, becoming familiar with the layout of the very large house. In the main living room, people were mostly talking, getting to know each other. Bill and Pam felt at home in their costumes, seeing that most other people had similar costumes that exposed those parts worth exposing.
Wandering down a hallway, they paused at the doorway to a large bedroom, where they saw a very hot woman on her hands and knees on the bed, being serviced by three men. Her husband was off to the side, being sucked off by two of the wife's, while the third wife was on her back, her face being straddled by one of the women suck off the husband.
