"Hey Lexi, can you come here for a second?" Mom calls to me from her bedroom.

Ugh... what does she want now?

I think, groaning to myself as I walk into her bedroom. Mom is lying on her bed, looking at something on her laptop. Despite being 49, turning 50 in a week, she looks amazing. She is very pretty, has long, curly brown hair, probably a D-cup and thick thighs and an ass that drives men crazy. Unfortunately for me, I didn't inherit any of that, except her hair. I have B-cup breasts, an average sized rear and her pretty face and hair. At 19 years old, I was still sexy, but I didn't radiate sex appeal like Mom did.

"You figure out what you want to do for your birthday yet?" I ask her.

Mom shrugs, "I'm still thinking about it. It is a big birthday, so I want to do something special. I did want your advice on outfits tonight. I am going out later and want your advice."

"Alright. Let's see what you have in mind." Mom closes her laptop and stands up, and undoes her bathrobe. Her large breasts are restrained by a lacy black bra and as she walks to the bathroom, I get a flash of her matching panties. From this distance they hide her nipples and vagina, but any closer and I might be able to see through the thin material. This would probably embarrass most girls my age, but Mom and I had always been really close. Especially after my dad left us. "Who's the lucky guy?"

Mom smiles as she hangs up her robe in her bathroom. "Well I'm going out with Lisa tonight, so who knows. Maybe I'll find a man, maybe I won't." She says, going into her closet. I sit down on the edge of her bed and watch her look through her clothes. She pulls out a form fitting dress and holds it up against her body. "This one?"

"Good choice, but maybe there's something better. Especially if you're looking for a guy." I reply. Mom hangs the dress on her door and keeps looking.

"What about you? What are your plans for the night?"

I shrug, "Honestly, I'll probably just stay here and hang out. I'll stay out of your way if you bring someone home though."

"A night to yourself... I wonder what your going to do here all alone?" Mom asks, chuckling to herself. "Maybe I'll come home and hear some moans coming from your bedroom." I roll my eyes, pretending I didn't hear that. "This one?" She says, holding up a tight black sleeveless dress.

"I think we found a winner." I say, with a thumbs up. "If anyone is going to be getting attention tonight, it's you."

Mom laughs, "If this is what you think will do it!" She turns around and unclasps her bra. She tugs the top over her head and adjusts it, making sure her nipples are covered by it. "Well?" She asks, spinning around for me. The dress tightly hugs her curves, stopping just below the middle of her thighs.

"You look sexy!"

Mom smiles, "Thank You!" She runs her hands over her sides as she moves her hips side to side, as if modeling. I jokingly whistle and catcall. Her phone dings from across the room. "Can you hand that to me? Lisa's probably here."

"She is." I reply, sneaking a glance at the screen before handing the phone over to Mom.

"Alright. Love you sweety. Have a good night!"

"Thanks Mom, you too! Use protection!" I jokingly call from her bedroom as she tugs on a pair of black heels and makes her way down the stairs. I slide off of Mom's bed and make my way back into my bedroom, wondering exactly how I'm going to be spending my Friday night.

Maybe I'll hear moans coming from your room...

I replay in my head, feeling a sudden desire to play with myself.

"It has been a while..." I say to myself. "And it's not like Mom cares. She bought me this for my birthday last year." I say, reaching into my dresser and pulling out a vibrator. It is shaped like a normal penis with a head and several veins running along the length and is made of a pink plastic. It is about 2 inches thick and about 9 inches long with a slight curve on it. I look it up and down, contemplating using it.

Mom did imply that I was going to do this.

After a minute of looking the toy up and down I smile to myself. "It's not like I have anything else to do tonight." I grab a towel from the bathroom and lay it out on my bed before I start to strip down. First, I toss my shirt onto the floor, before dropping my pants. I lie back and close my eyes, biting my inner lip as I slowly massage my own breasts. I quickly feel my nipples start to harden through my bra. I lean forward for just long enough to unclasp it and toss it to the side.

I start to gently squeeze my own breasts, sighing with pleasure as my fingers trace circles over my small, hard nipples. I let my hands start to wander lower over my body, tracing over my bare stomach, causing goosebumps to rise up on my skin. The fingers on my right hand rub over my slit, sending shudders through my body.

Fuck...

I think to myself, feeling my wetness begin to soak through my panties.

I feel my clit begin to grow engorged as I trace my finger up and down, faster and faster. Finally, the urge is irresistible. I turn on the vibrator and it buzzes to life in my hand. Holding onto the base, I rub the bizzing shaft up and down, over the length of my vagina. I shudder at the stimulation. The buzzing toy quickly makes my juices start to flow and soon, my panties are soaking wet.

"Why bother with these..." I say to myself, lifting my hips off of the ground and sliding them down before kicking them off with the rest of my clothes. Looking between my legs, I see the tips of my inner folds peeking past my puffy outer lips. I feel my bald pussy, using a finger to gently rub my clit. I rub the buzzing toy over the length of my slit, shuddering as it stimulates my clit. My juices begin to coat the length of the dildo, and soon I can't tease myself any longer.

Setting the vibrate pattern to pulse, I slip the head of the dildo into my pussy. "Oh fuck..." I moan to myself as I begin to sink the toy into my cunt. I slowly begin to slide the toy in and out of myself, moaning each time. Every time I thrust the toy into my pussy it sinks deeper and deeper.

I bite my lower lip and pick up speed, rapidly pumping the dildo into my own cunt over and over again. My pussy feels and sounds wetter and wetter with each thrust. "Oh shit..." I groan, sinking almost the whole length into my pussy, before pulling the toy almost completely out, except the head. Closing my eyes, I lean back against the pillow and keep up my work. Before long, my legs start to tremble as an orgasm starts to approach. My moans quickly become louder and louder. Each thrust of the toy coats it with more of my juices, most of which drool off the base onto my thighs and hand. "Oh shit... that feels so good..."

I pick my head up and watch as I continue to fuck myself with the dildo. As my orgasm approaches, I close my eyes and lean back into the pillow, letting waves of pleasure wash over me. After another few deep thrusts of the buzzing dildo, I cum. Through the haze of pleasure, I can barely hear myself moaning.

After the bliss starts to fade, I pick my head back up and open my eyes. I slowly slip the dildo in and out of myself, letting myself recover from my orgasm. "Mom really knew what to get me." I say to myself, using my free hand to gently rub my clit while I continue to slowly fuck myself. I momentarily pull the dildo away and slip three fingers into myself, slowing moving them in and out, considering the possibility of making myself cum a second time.

After a moment of debate and fingering myself, pleasure wins out. I get off my bed and place the towel on the floor then balance the dildo on top of it. I kneel above the toy, using the head of it to gently part my pussy lips. I shudder with anticipation as I slowly lower myself onto the buzzing rubber cock. "Mmmhhhh..." I sigh, enjoying the sensation of the toy filling me. I balance on my toes and one hand on the ground while I use the other to grope my breasts as I start to bounce up and down on the fake cock.

I start to bounce slowly on the toy, gently playing with my breasts as I do so. Once again, I feel myself growing wetter and wetter as I tease my body. I close my eyes and roughly grope my breasts. Despite not being thought of as a slut, I'm certainly not a prude who is afraid of a good hard fucking. I smile to myself as I quickly tie my hair back into a long ponytail. I start to pick up speed as I bounce up and down on the dildo.

My moans grow louder and louder as I throw myself down onto the long, thick shaft over and over again. Grabbing roughly at my own breasts, I close my eyes and imagine a hot guy is below me, between my legs, his long hard cock filling my pussy. I feel myself quickly being worked to a second orgasm, my juices drooling down the length of the vibrator. Keeping most of the length inside me, I hump the bottom part of the toy, my moans filling the air. My breathing starts to grow heavy as I quickly hump the toy over and over again.

"Fuck... oh fuck..." I cry out, sinking completely onto the vibrator as it presses against my g-spot. My legs quiver once again as I feel myself pushed over the edge into a second orgasm. I cry out with pleasure as I lean forward against the towel, shaking and moaning with pleasure. After a moment of enjoying my orgasm, I sit up and slip off of the vibrator. I turn it off and suck some of my juices and cum off of the length.

"Mom really did good buying this..." I say to myself, as I stand up shakily. I hold onto the wall for a bit of support for a moment before I regain all the feeling in my legs. I toss the towel in the laundry room and then make my way into the shower. I turn the hot water on and let it run down my body.

After I get cleaned off, I throw on an old shirt that belonged to my ex. It is long enough to cover down to my upper thighs. I lie on bed, scrolling through Netflix, looking for something interesting to watch. Shortly before midnight, I hear the door open and Mom walk into the house. I listen for a second to hear if she brought anyone home with her. After hearing nothing, I open the door to my room and creep down the hall, wanting to sneak a peek just to make sure she's alone.

Mom is alone as she sits down at the table and looks through her phone. "No one interesting tonight?" I ask.

Mom looks up at me and smiles. "Not tonight. Lisa and I just had a girls night. We talked a bit about my birthday and what i should do for it."

"Any ideas?"

Mom shrugs, "A couple things I'm thinking over and she gave me a couple new ideas on top of that. But what about you? You changed." She says, nodding at the baggy shirt.

I smile, "Let's just say your birthday present for me was a very good call." Most girls would hate talking to their moms about masturbation and sexual stuff. But Mom and I had an understanding that we would always be open and honest with each other. And Mom always supported me, as long as I was making healthy decisions.

Mom smiles, "I'm glad you like it. Most girls would hate getting something like that from a parent."

I shrug, "I guess I'm not most girls."

Mom nods in agreement, "I guess not..." After a moment she says, "Goodnight baby, I'm heading up to bed."

"Goodnight Mom." I say, following her to my own room.

The next morning, I wake up the smell of cooking breakfast.

Mom never cooks breakfast!

I think, stretching with a grunt then getting out of bed. I walk down the hall to the kitchen wearing the same shirt I slept in. "How'd you sleep?" Mom asks, flipping over a pancake. Like me, she is wearing an oversized tee shirt, hers covering about the same amount of her body.

I shrug and rub the sleep from my eyes, "Good enough I suppose." What about you?"

"Good. I did a bit of thinking and came up with what I want to do for my birthday." The tone of her voice sounds both excited and nervous.

I sit down at the table and cross my legs, feeling the skin of my thighs covering up my bare pussy. "What did you have in mind?" I ask.

"Listen, this is kind of... strange. I want you to keep this between me and you."

"Of course Mom! Anything."

Mom swallows and sits down across from me, handing me a plate of pancakes and setting one down for herself. "You remember last night when you said you weren't like other girls?"

"Yeah." I answer, confused at where this is going.

"Well last night, Lisa told me about this service she knew of. That would do birthdays and other events. Basically, it is this company that has a bunch of guys they screen show up to where ever and then they have sex with you."

I laugh, "Like a gangbang? Like in porn?"

Mom nods, her expression completely serious. "Yes Lexi. Like in porn. But there's something else..."

"Wait you're serious?"

Mom nods again, "I am. The second thing is that I want someone to do this with me. Someone I've known for years and am comfortable with. I want you to be there with me for this."

My ears ring as she tells me this. I drop my fork and just look at her.

Is she being serious right now?

I ask myself in disbelief. "Mom... you know what you're saying right? Your literally asking the two of us to have sex with a bunch of men together."

She nods, "I'm only asking you because of our relationship. I was thinking we would make this a weekend trip. We head into the city and get a fancy hotel room. Spend the night out, grab a nice dinner. Saturday, you and I sleep in, get ready and the guys all come over later that night. Sunday, we wake up whenever and leave."

I swallow, lost in thought, "I... I..."

Mom sighs, "If this is something you don't want to do, that's fine. As your mother, I love you and respect your decisions. And if this seems like it's something that-"

"I'll do it." I hear myself say, cutting her off. Mom stares at me for a second, and I repeat myself. "I'll do this with you. I want your birthday to be great and I hope this makes it amazing."

Mom smiles at me, "This is great! I don't want you to feel like you have to do this for me."

"Mom, I just want your 50th to be special, so let's do this."

Mom smiles at me. "Thank you. I'll pull up the information after breakfast and we can set this up." We eat breakfast, my heart pounding in my chest as I think about what I had agreed to.

Mom and I are going to get gangbanged...

I think over and over again in my head. After dinner, Mom pulls out her laptop and types away for a couple moments, before calling me over. "I just booked us the penthouse of a really nice hotel. Now for the important stuff..." She says, showing me the sight.

It is plain, with a drop down menu for the number of partners desired. "I think we want multiple." I say, pointing to the screen. Mom nods and clicks on it. Another page comes up, asking for location information.

"Hotel... address... room number...date... time..." Mom mumbles to herself, typing in the information. "Number of men? Oh, and all are guaranteed to be clean! That's good!" She asks, looking at me.

"It's your birthday." I reply, wondering how many mom will chose.

"There's two of us so... want to go ten? Five for each of us?"

I swallow, thinking about fucking five random guys.

It is her birthday and this is what she wants...

I think. "Five each sounds good to me."

"Condoms mandatory? No to that... Can they get rough with us?"

"Of course." I say, a coy smile on my face.

"Safeword?"

"Lemon." I say.

Mom laughs, "Why lemon?"

"When's the last time you said lemon during sex?" I giggle back, partly at my choice in word and partly at the absurdity of the whole situation.

"Fair enough. You ready for this?" She asks, hovering the mouse over the submit button after putting in the payment information.

"Yes." I reply, feeling nervous for this already.

Mom clicks it and after a second, a confirmation notice pops up. "All booked!"

I smile, "I hope you like it. Will this be your first time doing something like this?"

Mom nods, "I did have a threesome with two men once, but this is my first time with more than that and taking on multiple guys with another woman."

"Fair enough."

"Oh... speaking of another woman, I think we're going to need to be comfortable being naked around each other for Saturday."

"What did you have in mind?"

Mom hesitates for a second before speaking, "We should get naked just to get used to seeing each other's bodies."

I hesitate. Mom and I are and always have been very open with each other. We saw each other in our underwear frequently, but this would be something totally new. "I... that seems like the best way to do it." I finally say, reaching down and gripping the hem of my shirt.

"I'll go first." Mom volunteers. She quickly tugs her shirt over her head and I stare at her naked body for a moment. Her large breasts are each topped with a large, pink nipple. Her stomach is fairly flat, looking down her body, her pussy is bald like mine. Her soft folds flower outwards, exposing her slit to me. I have to shake my head to stop from staring as I take my own shirt off.

My heart pounds hard against my ribs as Mom and I look at each others naked bodies. "That's new." she says, nodding at the tattoo of ocean waves on my ribs, below my left breast.

"I got it as a 19th birthday present to myself."

"Looks sexy baby. When we're both home we'll just stay naked until we get used to it." Mom says, walking off, either to hide from me or to actually go do something. Either way, I glance at her thick ass as she walks by. The bottom curves of her rear and her upper thighs have just a hint of cellulite, but other than that, her body is amazing. I try to shake that thought out of my head as I head to my room and lie on my bed, wondering what exactly I got myself into.

"Lexi? Wake up." Mom's voice says, calmly into my room. I slowly open my eyes and blink.

Must have taken a nap.

I think, sitting up in bed. A glance at Mom tells me she is still naked. "I think we should go buy some lingerie for the weekend. Something that matches."

"Really?"

She nods. "Yes. My treat?"

"Let me get dressed." I sigh.

+++

Mom and I walk into the lingerie shop, and fortunately it is almost completely empty. There is one couple browsing sex toys, but other than that Mom and i basically have the place to ourselves. We make our way into the back of the store, walking past corsets, to bras and panties. "What color are you thinking?" I ask.

Mom shrugs, "Something sexy but cheap. I don't want to buy something nice then have it be ruined." She says, holding up a sheer red bra to her chest, before checking the price tag. "This and some matching panties?" Mom asks.

I shrug, "Maybe... what about this?" I ask, holding up a sheer white nightie.

Mom shakes her head, "As sexy as that is, I want something a bit... sluttier."

"This then?" I ask, holding up a bodysuit. Mom takes the package and looks it over. It is a bodysuit with large squares of skin all over the body. It "covers" from the feet up to the chest, and going down both arms. Mom looks it over and reads the package.

"Looks good to me. But don't get attached, it might not survive."

I laugh, "Something tells me you're going to like it that way."

Mom gives me a grin, "That is a possibility... but I think you might like that too."

"A girl never gives away her secrets..." I reply with a sly grin.

+++

The rest of the week passes both quickly and slowly. As Friday approaches, I get more and more nervous. Throughout the week, neither Mom or I wears any clothes, and I actually start getting used to seeing her naked form, but that does nothing to ease my nerves for the ordeal we have ahead of us.

On Friday in the early afternoon, Mom and I start driving to the city. We both made sure to pack our lingerie and some nice going out clothes for tonight. "So... are you ready for this?" I ask.
