Karen and Emily took special care in preparing for their double date that night. Their boyfriends, Rod and Bill, had worked it out to invite both of the women to a swing party, and everyone understood that the name referred both to the classic music and the style of the party, which would feature exchange of partners for sex.
Both donned their nicest silk lingerie and made certain to apply perfume to their intimate places as well as other spots, such as behind their knees. They did wear soft chenille blouses and rather short skirts for the dancing. Emily, who was all of 24 but very self-assured, had a curvier figure but little Karen, who was 23 and only 32A on top, had become far more confident during her already significant career as the principal dominatrix of their household. Emily had placed her two older sisters, Leslie and Linda, under Karen's command. And most recently, Karen's mother, Marian, had come to live with them and had been subjected to Karen's fiercest discipline.
Leslie and Linda were required to keep little conduct books, which Karen would use to enter their misdeeds for later consideration during punishment sessions. Marian was normally required, unlike the others, to sleep on a small mat beside her daughter's bed and was also made to wear a very restrictive chastity belt that Karen's friend Maria had made for her. The belt had holes in appropriate places for urination and defecation but Karen had a key with which she could close those openings partially or completely, which would mean Marian had to ask permission for the belt to be opened for her to relieve herself or fear having an accident which would surely earn her severe punishment from her dominant daughter.
The boys turned up dressed nicely in sport jackets and ties; Emily and Karen immediately hit it off with the others at the party, all of whom were attractive and friendly. Neither was upset when two other men, likely no more than a year or two older, invited them to join them in another room and began making love to the girls simultaneously. Both girls figured that it was fine being together—even when the actual sex started—rather than be involved in it with everyone watching.
Todd and Chet, their two new acquaintances, were good kissers and Emily and Karen happily shed their outer clothing as the guys stripped down to boxers. After lots of cuddling, they were invited to remove their bras and each boy slipped his girl's silky panties down and off, proceeding to provide plentiful oral attention to Karen's and Emily's pussies.
After that, the two found themselves pleased to be lying next to each other as Todd and Chet impaled them with their sizeable equipment. Karen had once suffered the sorrows of being a wallflower growing up, but now she found she absolutely loved to fuck. After everyone managed to come almost at the same moment, the room erupted in good-natured smiles and hugs.
The girls decided it made sense after this enjoyable interlude to put their clothes back on and they joined their original dates, who had also enjoyed delightful intercourse with another pair of welcoming women in yet another room. All four decided that after a few more dances, they were ready to return to Bill's place and then they separated into couples, occupied the apartment's two bedrooms, and stripped down for more sex.
After a few more cums, both girls were filled with both the drinks they had ingested and the cum in their pussies. They had not lost awareness of their surroundings, though, and kissed Rod and Bill good night as the boys dropped them off at Emily's spacious place. The girls were giddy with pleasure from the delights of multiple sex partners as they walked up to their apartment.
Once they entered, Emily's sisters and Karen's mom greeted them respectfully. Emily took charge, which surprised all of them because she had so often delegated direct supervision of all three submissives to little Karen, whose dominant side had become much more evident. But Emily still had some authority over even Karen, who in the end remained her protégé.
Emily rather abruptly ordered Leslie and Marian to strip to their panties only and join Karen and her in the commodious bedroom Emily occupied as head of the household. She bade Karen sit next to her on the side of the large king-sized bed and spread her legs under her short skirt, having, as had Karen, not bothered to put her panties back on after the sex at Bill's.
Emily merely pointed for Leslie to crawl between her younger sister's legs and start to lick Emily's dripping pussy clean. Then Emily motioned to Marian to do the same for her own daughter, Karen, and soon both submissives' tongues were licking the two pussies as Emily and Karen were cleaned from the cum of the two sex partners with whom they had so pleasantly fucked.
Once Karen had writhed and bucked her hips in response to her mother's tongue teasing her risen clit, she came hard and added her own juices to the spicy cum cocktail Marian had been swallowing as the combined cum seeped out of Karen's tight little vagina. Emily reacted similarly and also spiced her dripping cum with an occasional jet of strong pee for Linda to taste as she licked her younger sister's snatch.
Marian began licking less as if to signal that she hoped Karen had been sated. Karen took umbrage at her mother's assuming that her oral service was ending and told her that she had earned herself a hiding for presumption. Shortly then, Marian was ordered to pull down her panties and get across little Karen's lap for a spanking.
Karen always enjoyed having her mother across her lap in the spanking position, because she recalled how her mother had disciplined her in this way during her childhood and even into her adolescence. The diminutive dominatrix began spanking her mother's commodious bottom-cheeks and then ceremoniously inserted her finger deep into Marian's dark-colored anal opening.
Withdrawing her finger and showing the now amused Emily a finger displaying a brown smudge from inside Marian's anus, Karen told Emily that she now needed to "check the oil" frequently with Marian, meaning that she would insert her finger into her mother's most private place to see if a bowel movement was imminent.
"It looks like that big girl will need to make a doody soon," Emily giggled as she looked at Karen's smudged fingertip. Marian, still over her daughter's lap, cringed and her face grew as red as Karen had made her bottom.
