Chapter 1: New Beginnings
Sandy, and her two daughters, Katie, 21, and AJ, 18, met Andy on the internet. There was some mutual attraction on both counts. The women were attracted to Andy's dominant personality and his way with words, and he liked the fact that they were sexually open with each other, to say the least. Katie, was thin (34C-24-34) and brunette like her mom. AJ, who had apparently gotten her looks from her father, was blonde and 36D-24-34. Sandy's measurements were a respectable 36C-27-35. While all of the women were quite beautiful, none of them had any question about who was the sexiest and prettiest. AJ stood tall above both her older sister and her mom in the looks department. Her face was prettier, her body was curvier, and worst of all for the other two, she was also smarter and more confident.
Sandy had to admit to herself that she wasn't overly fond of the latest developments that had taken place. At Andy's request, the girls had now started calling her "slut" or "mommy-slut" in private, and calling her by her first name in public. So while all of their friends would refer to their mothers as "mom," Sandy was routinely called "Sandy" by her daughters in front of their friends, or worse, HER friends... or the girls' friends' parents.
The first time it happened was at a house-warming party for the family of one of Katie's friends. Sandy and her daughters all attented the party, but Sandy didn't quite realize what she was in for. Everyone was sitting around, talking innocently, when AJ, ever the bold one, loudly said "Sandy, would you be a dear and get me some more punch?"
Sandy's cheeks turned bright red as everyone took note of such a minor thing as the girl calling her own mother by her first name... and also, the lack of a "please" of any sort. They also noticed that Sandy very quickly fetched her daughter some punch, and that AJ barely acknowledged her when she took the cup from her mom. Katie especially noticed.
By the end of the night, both girls had gotten used to calling Sandy by name. To her own horror, Sandy never really got used to it, and worse, she found that her pussy throbbed every time it happened. She knew that the girls were following Andy's order, and that she, Sandy, was obeying Andy in obeying them. She hated that she enjoyed being treated so cruelly by her own flesh and blood, but she had to admit it... even if only to herself when she was alone in bed at night.
As they approached the car, AJ whispered into Sandy's ear that she would be driving home. Sandy never felt so low as when she had to hold open the car doors for each of her daughters, with AJ in the driver's seat... that's where Sandy was supposed to sit. She's the one who paid for the damned car. Unfortunately, her pussy was now doing her thinking for her, and it loved every bit of this humiliation. She opened the back door for Katie... surprised that she wasn't going to force the mother to take the back seat, but of course there was a reason Katie's choice of seat. Once they got into the car, the girls resumed their taunting of her, starting with AJ, the youngest, and most beautiful of the three.
"Did you have a good time tonight, slut? I just loved the look on everyone's faces when you had to pee so badly, and I asked you to get me some more punch and you actually got me my punch rather than going to the bathroom. When I didn't take it from you right away (actually not even looking at her or acknowledging her presence), I soooo hoped you'd pee yourself right there. I'll admit that a big part of me was disappointed that the bathroom opened up right when it did for you."
Blushing even worse, Sandy replied: "Yes, dear... I did have a good time... but I wish you hadn't been so cruel in there. Andy told you to start calling me by name, but he didn't say you had to start odering me around like a maid or something," she said, almost in a whine.
Katie joined in "No, slut, but it sure did add to the fun, didn't it? I'll bet that pussy of yours is wet already, isn't it, mom... mmee-slut?" She giggled to herself as she added the end part. Sandy wasn't sure if Katie had said it that way to torment her more or if she had almost slipped into reverting to calling her mom, but either way, she had to admit the truth.
"Yes, Katie... my pussy IS wet."
AJ smiled and said "Why don't you pleasure yourself, then, slut? I know that a slutty pussy needs attention."
Sandy, sinking deeper into her own humiliation, resisted "Thank you, but I think I'll wait until I get home to do that... errr... I mean... IF I do it, it will be at home." She blushed at her slip... her admission... but knew that the girls knew her too well anyway, so it there wasn't much point in fighting it.
Katie leaned forward and whispered into her mom's ear "But nobody will ever know, but us, slut. I know that Andy has forbidden you from wearing panties, so it's just a matter of lifting that short skirt, spreading your legs, and moving your fingers to wear they so desperately want to be. You DO want to touch yourself for us, don't you, mommy-slut?"
As if in a trance, Sandy's hand moved between her legs as they spread as far as the car seat would allow. She starting rubbing her juices over her clit, and was humiliated ever more to learn just how drenched her cunt was from the ordeals of the evening. Katie spoke up once again:
"Do you want to know my favorite part of tonight, mommy-slut?" Sandy just whimpered and nodded.
"It was the fact that Andy only told us to start calling you Sandy in public and slut in private. He never told you that you HAD to obey us. You did that ALL on your own!" Sandy's mouth dropped as she realized the truth of Katie's statement, and her cunt spasmed all over her fingers as her orgasm hit her like nothing she had ever felt before. It was true. She wasn't ordered to submit to her daughters' humiliation in public, but a part of her craved that, loved it... ate it up and came back for more... almost begging for more. A tear ran down Sandy's cheek as her second orgasm hit her.
Chapter 2 - Sinking Deeper
Within a week, the girls were taking newer liberties with their mom on a daily basis. The Saturday of that week, the girls decided to stay in and watch a movie. They urged their mom (okay, ordered might be a more fitting term) to stay in and watch the movie with them. Katie rented the movie, and to Sandy's astonishment, she had rented a lesbian porno movie. AJ ordered her mother to strip as the movie started getting good. Both girls enjoyed pinching their mother's nipples and holding her hands away from her sex as she tried to relieve her own frustration. She was now beyond caring if they saw or not, she wanted to pleasure herself.
