My name is Tess, and I run a women's clothing store with my twin sister Angie. We're a pair of cute, perky redheads in our mid-twenties with a knack for finding fun and trouble ... often at the same time.

At our boutique, we are often given the opportunity to see beautiful women in their underthings, sometimes completely naked ... and since Angie and I are both lesbians, we seize any opportunity to do just that. Now and then, though, my sister and I score something much hotter than a quick peek. This story is about one of those times.

It was around seven-fifteen on a Tuesday evening, and the store was almost empty. There were only two customers -- a mother and daughter who were indulging in some casual shopping. The two ladies really stood out to me because they looked a great deal alike and were both very attractive. The mother could not have been more than thirty-five, and the daughter seemed to be about fifteen.

Something about the mom and the way she looked at me as she passed by made me think that she might be into women ... I couldn't explain it, you just develop a sixth sense for that kind of thing if you play the field as much as Angie and I do. Anyhow, I found myself watching for a chance to get her alone.

The daughter was looking around while the mother headed for the changing rooms to try on some things she had picked out. Seeing my opening, I gave the high sign to Angie, letting her know I was about to make a play for one of our customers. She nodded slightly, flashing me a quick thumbs-up, and I was off.

Pulse racing, I walked to the room occupied by the mother and tapped on the door. Thinking it was her daughter, she immediately replied "Come in..."

When I opened the door she was down to bra and panties and was surprised, at first, to see it was me. Slipping inside and closing the door, I told her that I simply wanted to know if she needed assistance -- my eyes slowly taking in every inch of her as I spoke.

She was taken aback for a few seconds, then relaxed, a knowing smile forming on her lips as she realized why I was there. I smiled back, thrilled that my instincts about her sexual tastes had been correct. I was tingling with excitement -- the huntress, out for wild game.

In her hands she had a see-through nightgown that she'd picked out ... and in my most sultry voice, I purred, "Put it on ... I'll bet you look stunning in it."

Her eyes never leaving mine, she unhooked and removed her bra, dropping it carelessly to the floor ... then she slipped the nightgown over her head and posed for me, a saucy grin on her lips.

Continuing my game of seduction, I softly said, "It's perfect, very sexy ... but that gown isn't meant to be worn with panties." I moved closer, slowly licking my lips. "Let me help you."

"I'd like that," she murmured, her face alight with anticipation.

Kneeling before her, I reached for the hem of the nightgown, hoisting it up before I slid the lace panties she wore down to her ankles, revealing a gorgeous pussy. I gazed in awe, licking my lips at the mouthwatering sight. She had a neatly trimmed pubic triangle, and her sex was dewy with moisture ... obviously, she was ready for me.

Without a word, I buried my face between her thighs and began to lick lustily at the pink flesh.

Her cunt was juicy and delicious, and my lips were soon dripping with her honey. She was still on her feet, leaning back against the changing room wall, and I could feel her legs tremble as her pleasure mounted. I fumbled a hand beneath the skirt I wore and slipped it into my panties, craving a little self-stimulation while I went down on this beautiful stranger.

Suddenly a voice just outside the door said, "Momma? Are you in there?"

We both froze. The woman fought to regain her voice, then gasped, "I'll b-be right out in a minute, honey."

"Oh, take your time ... I just wanted to tell you that they've got some really nice Capri pants here, that's all. I'm gonna go look at the shoes."

We could hear the girl moving away, so I went back to eating her mother's pussy ... fucking her with my tongue, then moving up to nibble at her clitoris.

She was shaking violently by then, and I knew she was about to come. So I placed two fingers at the entrance to her cunt and, with a single stroke, drove them deep inside her.

"Oh, my God..." the mother whimpered ... then she quickly covered her mouth to stifle the moans as her climax hit. It was an intense one, too -- lasting nearly a minute or so. She had a hard time keeping still, but I somehow managed to stay with her, my mouth glued to the woman's cunt as her pleasure crested and waned.

I brought myself to a quick climax with busy fingers while my lips were still buried in the sticky pubes, licking the woman until she finally slumped against the wall, sighing blissfully as I gently nuzzled her mons. My orgasm wasn't as intense as hers, but it was enough to calm my raging lust ... for the moment, at least.

I raised my face from her bush, and she staggered over to the bench and clumsily sat with a thud, dazed and flushed, gasping for breath. I crawled between the woman's spread thighs, kneeling to give her a hot, pussy-wet kiss, which she eagerly returned ... then I rose to my feet, smiled down at her and whispered, "Rest for a little while, honey ... I have to step out for a bit." I gave her one more quick kiss on the cheek. "Wait here."

I cautiously peered out of the dressing room ... relieved to see that the daughter had moved to another part of the shop.

As I moved away from the changing room, I caught Angie's eye, wordlessly signaling to her that she should pay a little visit to the room I'd just vacated. My sister and I loved to share women between us, and I figured that this particular lady would totally be up for taking on Angie, too. Of course, since my sister and I look and dress alike, the mother might not even figure out our little game...

Angie eagerly nodded, moving to put up the CLOSED sign and lock the front door. As for me, I took a moment to compose myself, wiping my mouth and taking a quick hit of breath spray ... then I approached the girl, who was now toting a few items she'd selected from the racks.

"Hi," I cooed, drawing near, "and welcome to our shop. I'm Tess."

The girl gave me a lovely, slightly bashful smile. "I'm Mandy."

She really was an exquisite creature ... a blonde teen of about fifteen, ripening into a gorgeous woman. And a wild impulse suddenly hit me: how amazing would it be to fuck a mother and her daughter on the same day?

In my warmest, most sensual voice, I murmured, "I've been in the stock room, helping your mom find a few things ... but now you have my undivided attention." Then I hit her with a playful wink.

Mandy grinned. "Um, okay..." She showed me the hangers she was carrying. "Look, I've found some really cool things already."

"Good!" I laughed. "Let's have you take some of these for a test drive."

Even after my hot romp with this cutie's mother, I was craving more ... and Little Miss Mandy was turning me on something fierce. This was absolutely crazy, but I felt a powerful urge to make a move on her. What can I say? I've always been up for a kinky dare.

No one was in the store but Angie, myself, and our two hot customers ... and it was time to play. I just hoped that this perky teen would prove to be as easily persuaded as her mom.

"Let's go in here," I told Mandy, steering her to the changing room at the far left corner of our store. Now, I have to tell you about this particular room, because it's important to the story.

Angie and I had it designed to exact specifications when we had the space remodeled. We call it the Fuck Me Room. It's mainly used by customers to try on clothes, like any other changing room ... but it's also our own personal space for when we want to spend some quality time with a girl or woman who's up for sexy fun.

For starters, it's twice as large as the other changing rooms, with a floor spacious enough to stretch out on. We had extra-soft shag carpet put in, the light switch has a dimmer when you want things softly lit and romantic, and we got the walls soundproofed. There's even a little closet nearby where we store pillows and blankets, for when we want to get especially cozy.

So if one of our girlfriends drops by, and things aren't too hectic customer-wise, Angie or I just might take a little break and join her in the Fuck Me Room for anything from casual making out to a hot, wet sixty-nine. And sometimes, after work, Angie and I hole up in there with the pillows and blankets and enjoy a long, leisurely fuck of our own.

That's right ... my sister and I are lovers. She's been my life partner, ever since we first became sexually intimate as teenagers. And even though Angie and I share an apartment, sometimes we simply can't wait until we get home to get each other off ... and that's where our special room comes in.

Anyhow, I guided Mandy inside ... glancing back at my sister, who was staring after me. Our eyes met, and she shook her head incredulously, but with a wicked grin. She knew exactly what I was up to. Then she quickly turned away, moving toward the room where the mother was waiting.

Entering after the girl, I quietly closed the door behind us. She was clearly surprised that I had followed her into the changing room, but said nothing.

With a smile, I asked her to get undressed so she could try on some of the items she had brought along. Mandy hesitated for a moment, then quickly stripped down to her underwear. Her breasts were small but lovely, her nipples clearly visible through the bra. She wore plain white cotton panties, and looked delicious in them.

I casually studied her. "Hmmm ... have you ever thought of wearing a thong instead?"

She shrugged. "I've always wanted to try one, but -- well, I don't think Momma would approve."

"Well, they are incredibly comfortable." I murmured, sidling close to the girl. "Would you like to see the one I'm wearing... ?"

She slowly nodded. I could tell that the idea interested her.

Her eyes were locked on my lower half, clearly waiting for me to raise my skirt ... instead, I surprised her by unfastening the catch and dropping it to the floor, exposing my jet-black thong to her wide-eyed stare.

"Wow," Mandy whispered, "that looks really hot!"

I could tell that she was aroused ... and my heart throbbed at the possibility that this lovely creature just might be up for a little girl/girl fun. Like mother, like daughter?

Anyway, I decided to go for broke ... and, with a smile, I purred, "Would you like to try my thong on for yourself? You can if you want." I licked my lips, then added, "If you look really hot in it, maybe I'll give it to you..."

Mandy's eyes danced with nervous excitement. She stood there for a long moment ... probably trying to decide if I was playing some kind of twisted joke. Finally, she slowly parted her lips to whisper, "All right."

My gaze never left her as I slowly slipped the thong off ... and I grinned as the girl gaped at my bare vulva.

"Haven't you ever seen a shaved pussy before?" I cooed.

Mandy blushed, embarassed that I'd caught her staring. "O-only in pictures ... It's, um, really sexy."

Moving closer to the girl, I softly said, "You can try on my thong... but you have to lose the panties."

Her eyes widened in surprise ... but then, with a shy smile, she pulled her panties down and off. I still wasn't quite sure if she would let me fuck her or not, but seeing this sexy teen's partial nudity was reward enough.

I gazed down at her pussy -- a beautiful pink slit, framed by a sprinkling of blonde down. My mouth watered at the thought of tasting her.

Without a word, I handed Mandy the thong ... and she stepped into it, tugging the skimpy garment up and over her hips. I took her arm and turned her toward the mirror. We were both studying her sexy body in the mirror, though I noticed that she was also stealing little glances at me, especially my naked lower half.

That's when I knew for certain that I could have this teen cutie, just like I had taken her mother. I moved in for the kill.

Placing my hands on the Mandy's shoulders, I leaned in to whisper, "Oh, you are a lovely young woman ... I think you're sexy enough to be a model."

She blushed and said, "Aw, no way..."

"It's true," I breathed as I undid her bra from behind, dropped it to the floor, then wrapped my arms around her waist. I brought my lips close to her ear to whisper, "Oh, babe, you're irresistible..."

As my lips brushed her ear, she closed her eyes and leaned back into me. I began to kiss her neck, then trailed kisses down the soft skin of her back, along her spine. She moaned softly as my mouth inched lower and lower.

That was when I glanced in one of the large mirrors and saw that the door of the changing room was now slightly ajar. I froze at the sight of Mandy's mother peeping through ... still wearing the see-through nightie I'd left her in, with Angie close behind her. Very close.

A surge of panic raced through me as I braced myself for the inevitable explosion of motherly rage ... then I realized that the woman wasn't making a move to stop me from having her daughter.

Whoa ... what's happening here? I thought. Is she ... getting off on this?

My nerves were still jangling ... but my sexual hunger was growing more intense by the second. Knowing that this lovely teen's mom was spying on us, but not interfering in my seduction of her girl -- well, as you can imagine, it had me hotter than a pistol. Damned if I knew what was going on in this woman's mind, but there was no way in hell I was stopping now. With a secret smile, I resumed my lovemaking.

As I nuzzled my wicked way down Mandy's back, she bent over, placing both hands on the bench in front of her. I knelt behind and slowly tugged the thong down with my teeth. She stepped out of them, revealing a flawless ass. I spread her buttocks apart with my hands, stealing another quick glance at the reflection of the slightly open door ... only to see Angie and the girl's mother embracing. My sister had her back to the door, and she was kissing the mother, who was watching me and her child over Angie's shoulder.

Wanting to give our audience a good show, I licked my lips, then lowered my face to Mandy's ass and slowly, slowly trailed my tongue up her butt crack. The teen shivered, whimpering softly. Pressing my mouth between her cheeks, I gave her anus a open-mouthed kiss, then circled the rosebud with the tip of my tongue. Finally, I risked another peek into the mirror.
