*****
Alex and Haley Dunphy were sitting in their living room/ kitchen a.k.a. their only room other than the bedrooms, holding hands and waiting for their Mom to arrive. This wasn't at all uncommon, as whenever they were alone together they were free to do normal couple stuff, even if it was as simple as holding hands, and whenever they had family coming over they were restricted doing just that and then pulling away from each other when their family showed up.
But today was different. Very, very different. Why? Because they were waiting to find out if they still had a family, or if everyone else had found out about their affair, and were coming over here to disown them. All because Haley had zero self-control.
To be fair it was partly Alex's fault. After all, she hadn't exactly shot down the idea of seducing their mother into their bed. It would have been the right thing to do. The smart thing to do. But it had just been so hot, and Alex didn't think anything would actually come of it. It was just a harmless fantasy. Oh how wrong she had been.
Because Haley had seduced their Mom, and both of them had fucked her, or more accurately been fucked by her, and then after a entire night of intense lesbian incest it was radio silence until an ominous text had promised a visit. And now all they could do was wait, and silently hold hands for comfort.
When the doorbell finally rang both sisters ran to the door, Alex opening it up to find to her relief that their mother was standing there alone. There was then some awkward silence and then Alex stepped aside to wordlessly let her Mom inside and close the door behind her.
There was then more silence, before the older woman cautiously stepped towards Haley, who grinned happily as their Mom stepped into her personal space. She then closed her eyes, leaned forward, and sure enough there mother leaned down and kissed her, causing a wide smile to cross Alex's face as the next few wonderful minutes she watched her Mom and her sister, a.k.a. her two lovers, make out with ever increasing passion.
"You're such a bad girl." Claire gasped when she finally broke the kiss, although she barely pulled away and rested her forehead against Haley's.
"Yeah I am." Haley grinned proudly, "I'm a bad girl, and so is Alex. I made her one. Isn't that right Alex?"
"Yes." Alex admitted huskily, "We're both so bad."
"Don't you want to be bad too Mommy?" Haley asked softly, caressing her mother's face, "It's fun, and you do want to have fun with us, don't you?"
"Oh God, this is so wrong." Claire whimpered, before kissing Haley again.
Haley giggled as her Mom leaned in for the second kiss, and then again when the blonde pulled away again to look at the other brunette, prompting Haley to encourage her, "Go on Mom, kiss Alex hello. I know she wants you too, almost as badly as you want to do it."
There was then a brief pause before the older woman stumbled towards Alex. She received a gentle push from Haley, or more accurately a physical one as well as a verbal one, but it didn't seem to matter. No, it was now very clear that their Mom had come back to fuck them again, something which both sisters welcomed, just as eagerly as Alex pulled her mother against her body and then kissed her.
Just like with Haley the blonde was hesitant at first, but it wasn't long before she was pushing her tongue into the other brunette's mouth, causing Alex to whimper happily as she massaged her tongue with her own. Alex was so lost in that kiss she had no idea how long it lasted, only that it wasn't enough, and when it did unlike with Haley the older woman didn't completely pull away from her and pressed their foreheads together.
"Both such bad, bad girls." Claire growled, before grabbing the back of Alex's head, and then did the same to Haley's before pushing her daughters together, "Show me! Show me what filthy little sister kissing sluts you are! Mmmmm fuck, that's it, kiss! Kiss your sister! Oh fuck yeah!"
Claire loved watching her daughters kiss. She may not ever get used to thinking that, but it was true. They just looked so hot together. And so beautiful. They just put their all into it, making it obvious just how much they loved each other, and while that was wrong on so many levels Claire couldn't help be grateful that they had both found that kind of love.
Then Haley broke her kiss with her sister to kiss her Mom again, the three Dunphy women going back and forth as they made out with each other for a while. Along the way they caressed each other's bodies, although there was a certain area that Claire couldn't stay away from, and ultimately led to her grabbing Alex's top and pulling it over her head.
"Oh my God, when did your tits get so big?" Claire asked with disbelief as she cupped Alex's massive bra covered breasts.
This caused both girls to giggle loudly, and then Haley answered the question, "I know. She did such a good job of hiding them with her ugly sweaters and baggy clothes, and then one day I was like, oh God, I can't unsee the hotness. Then no amount of horrible fashion sense could keep me from lusting after my baby sister."
