Taking her relationship with her daughters to the next, ultimate, level required lots of preparatory work by Melanie Danes. She had spoken to Hazel, her eldest, when they were in bed together for the first time, after fucking at a hotel -- unsurprisingly, as Hazel was (to take a positive position on her sexual morals) up for anything, the teen was extremely supportive of the idea of a lesbian threesome with her Mom and sister. However, Ashley would be much more skittish about the idea -- whilst she was now a lesbian nymphomaniac, that was only with her Mom and to get her there had taken weeks of careful seduction; getting into a bed, with her sister also in it, wouldn't be the result of a quick chat over breakfast.
"Now remember," Melanie reminded her eldest daughter for about the tenth time, "There can be no hints from you, no clever remarks or little put-downs. Ashley can't know I'm fucking you and she certainly can't know we both want her to join us in a threesome."
Hazel pouted, rather prettily to be honest (though she'd been practising that same expression since she first got bosoms and realised the power that hot girls can wield), "Honestly Mom, I won't breathe a word."
"Nor flash your tits when you think she's not looking or bend over and wiggle that cute ass as I pass or try and sneak into my room -- anyway I'll be busy most nights."
"We've gone over this," Hazel moaned and looked out the window as another set of suburbs flashed by.
"It is important," her Mom reminded the nineteen-year-old.
"Yes," agreed Hazel with an exaggerated sigh as if she'd been asked to tidy her room so as not to conspire with her Mom to have sex with her sister. She remained silently looking out the window for all of ten seconds before she spoke again, "You know I'll be absolutely jonesing all week for some Mommy fucking."
Melanie smiled, "You'll just have to please yourself in bed."
"Hmpff," snorted Hazel, "Knowing you're fucking Ashley just down the way... I know what I'll be thinking about as I slide my dildo deep into my hot tight pussy," she said the last three words slowly and seductively, knowing the impact they'd have on her Mom.
Melanie licked her lips in lust, "Don't wear yourself out," she said, not that this was likely, Hazel was almost certainly as insatiable as her sister and Mom were, "Leave something for next weekend."
"When you're away for a works convention" Hazel raised her fingers to make the sign of speech marks for the last two words.
"And you're out of town with some college friends, I believe," Melanie grinned back. That of course was what they were telling Ashley, so they could sneak away and fuck from Friday evening to late Sunday afternoon. Having an affair was actually quite exciting and in some ways Melanie was disappointed the secret sexual dalliance would only last for a short while; however, the thought of having both her daughters servicing her pussy with their lithe tongues meant the illicit excitement of an affair was second best. "I'm looking forward to it."
Hazel grinned, flicking her hair back coquettishly, "Will you be thinking of me when you're banging Ashley?" she asked.
"That would be telling," her Mom smiled back, "But I don't play favourites so if I'm thinking of you when I'm fucking your sister, I may be thinking of her when I bang you."
"Who will you think of if we're in a threesome?" the teen teased back.
"I'll be too busy to think," Melanie said and pulled up at a bus stop a couple of miles from their home.
"Couldn't you have chosen a nearer one," grumbled Hazel as she undid her safety belt and her Mom popped the trunk.
"You can't be arriving home at the same time as me, Ashley would be suspicious," Melanie said, "Anyway it'll give me half an hour alone time with her; which gives me a chance to start work on her."
"I suppose," said Hazel, "Goodbye kiss?"
"Of course," said Melanie and leaned in for a lip-locker, their mouths opening in unison and their tongues dancing forward in passionate tango, hands sliding up and around the waist and up to the tits, as if they hadn't spent the last few days exploring every nook and cranny of they each other. They stayed like long enough for a bus to appear and then disappear, before Melanie reluctantly disengaged.
"You won't forget me?" giggled Hazel teasingly.
"Don't worry you won't be far from my mind, especially as I'll see you every day," her Mom replied.
"You'll keep me up to date with sis's seduction?" Hazel opened her door.
"Don't worry, I will and in a few weeks it'll all be out in the open," said Melanie; now she had just had to hope her new plan worked as well as her original one had.

There was no time to waste when she got home, Ashley was already up and waiting by the front door as her Mom came in, a half-opened book left on the coffee table beside her. "I missed you," she said, coming in for a quick kiss, as Ashley wasn't around to interrupt.
Melanie grabbed her daughter's waist and dragged her in for a longer one, her tongue driving deep into the teen's willing mouth and her body pressing firmly against the teen's so she could feel the large bosoms of her daughter squishing against her as she greedily grappled with the round rump, kneading it brutally with her fingers. Ashley kissed back just as passionately, standing on her tip-toes to get her head level with her Mom's and battling back with her own tongue as her hands reached down and squeezed at her Mom's ass with the same fierceness that her Mom was groping hers.
After half a minute Ashley pulled her head back, forcing her face into a sensible expression, "We need to stop Mom, Hazel could be back any moment."
They had thirty minutes, Melanie knew, and she wanted to enjoy them. She reached for the bottom of her daughter's pullover and hoisted it upwards, "She's not here yet," she replied.
For a second Ashley resisted, sense and sensibility winning out over passion, but only for a second before she raised her arm and allowed her Mom to pull off the top, revealing a bra which was barely managing to hold in her massive melons. As she reached around to undo the black lace garment, Melanie reflected, how, even a few months ago, her daughter's bras would have been much more sensible and attractive, it was only with her Mom's coaxing and prodding she'd gone for bras which were as much about showing her bosoms to the best advantage as comfort and practicality. The bra dropped to the ground, where Melanie left it as she instead moved in to suckle at her daughter's tits, her tongue flicking out around one nipple until she felt it hardening and then to its partner to give it the same treatment.
