Surprise Birthday Party

I look at the time at the bottom corner of my laptop screen as I sit on my bed. 9:04 AM. Through my closed bedroom door, I hear my mother's footsteps getting quieter as she descends the stairs. It is Saturday and she always leaves to do errands on Saturday mornings. I reach my hands down to the bottom of my t-shirt, but leave them there while I listen. As I wait, my eyes wander to the title of the story I had pulled up on the screen.

'Sandy's Naked Adventure'

In my head, I insert my own name. Caitlyn's Naked Adventure. As if I could ever do something so risky, but it drove me wild to imagine myself in the character's shoes.

Expecting to hear the closing of the front door, instead I hear, "Caitlyn. Can you please come downstairs?"

Letting go of the bottom of my shirt, I sigh and get out of bed. "I guess this will have to wait for a few minutes."

As I walk downstairs, my mother's enthusiastic voice greets me.

"Happy Birthday, Caitlyn! Eighteen years old. My little girl has grown up into a young lady." With open arms, she walks up to me and gives me a big hug.

"I made you a special birthday pancake!" she declares as she presents me with a plate. The pancake has a happy face on it created with whip cream and two raspberries. "There is more where that came from if you want," she says as she hands me a fork.

Wanting to get back to my room as soon as possible, I start wolfing down the pancake, not even bothering to take a seat. My mother looks at me with a curious expression. Maybe I should slow down so she doesn't think something is up.

"You are wearing something under that shirt, right?" She finally asks.

"Yes, mom." The shirt I am wearing isn't super long; it just stops near the top of my thighs. I very quickly lift the bottom of the shirt to show a glimpse of the tight shorts that were previously hidden underneath. As I let my shirt drop back down, I hope she doesn't ask if I am wearing a bra. I am, I would just feel embarrassed about lifting up the shirt above my chest to prove it. 'I am so weird. I am uncomfortable flashing my underwear for a couple seconds, but I get off imagining myself naked in front of a group of people.' Something I won't get to do, unless...

"What are your plans today, mom?" I shove another bite of pancake in my mouth as I await her answer, hoping she will confirm that she will be going out like usual. I could always lock my door to get some privacy, but I prefer having the house to myself so I don't have to worry about staying quiet.

"I have some errands to do. I'll be gone for like an hour."

Perfect.

"Then I guess I come back and sit here alone while my daughter goes and has a party without me." She makes a sad puppy dog face to indicate she isn't actually guilting me.

"It isn't a party, I am just going to hang out with Jess and Tricia to celebrate," I correct her, finishing my breakfast.

"And you are still sure you don't want to have a real party for your 18th birthday? You used to love birthday parties." Now the fake sad face is starting to look just a tiny bit more genuine. She is right that I used to look forward to my birthday every year, but I have become more introverted as I got older.

"I am sure. I would rather spend time with my closest friends than a big group of people. Besides, it would be too late to get something together this year."

"Yeah, I guess it is." She picks up her purse, walks to the front door, and opens it before pausing. "Oh. I forgot to mention that the pool can't be used right now. We have to get a filter replaced. Sorry if you were planning on going for a swim."

I look out the sliding glass door leading to our backyard pool. It is a nice sunny day, perfect for taking a dip, but I have other plans for my alone time.

"No worries, I have other stuff I can do." Like myself.

"Okay, I'll be back as soon as I can. Love you!" As soon as the door shuts, I hurry up the stairs back to my room. I close my bedroom door and in an instant, my hands are grasping the bottom of my shirt and pulling it up over my head. I drop the shirt on my desk chair and jump onto my bed and turn the laptop screen back on.

I start reading the story while idly brushing my fingertips up my legs and flat tummy. The premise of the story is simple: Sandra walked 30 minutes away from her home. She starts walking back, but every 5 minutes, she takes off an item of clothing. With what she is wearing, she will end up removing her last cover with 5 minutes still left to walk. As Sandra, gets closer to safety, she has to make more and more difficult decisions about what to remove.

"What would I take off right now?" I look down at my petite body and look at my tight pink shorts and my black bra. I close my eyes and imagine myself standing on the other side of my neighborhood. I get an idea and quickly peel off my shorts and panties before tossing the panties to the other side of the room and pulling my shorts back on. I can see the outline of my lips as the material tightly hugs my body.

I continue reading. My right hand slowly wanders down between my legs. I feel a wet spot beginning to form. My fingers rub gently in a circular motion. I let out a trembling moan.

When Sandra has to decide what her last item of clothing will be, I decide to continue playing along. I unclasp my bra and toss it aside. Still picturing myself outside, I raise my left arm to try to shield my breasts. It turns out Sandra makes the same decision, leaving herself topless 10 minutes away from her home. Still trying to stay covered, my left hand starts playing with my right nipple.

Finally, the moment arrives where Sandra needs to take off her last item of clothing. Without hesitation, I pull my shorts down and leave them at the foot of my bed. Now completely naked, my right hand returns to my soaked pussy. I could probably cum in less than a minute if I went for it, but I resolve to hold out until the end of the story. I have a feeling Sandra is going to touch herself when she gets home, so I will try to delay my release until then. That doesn't stop my hands from reaching up to knead my breasts and lightly pinch my nipples.

Sandra walks the final leg of her trip with her arms by her sides, not attempting to cover anything. I know she is a fictional character, but I am still in awe at her confidence. When Sandra reaches her door, she flips over the edge of the welcome mat to retrieve her spare key. She inserts it in the door, but instead of opening the door, she turns around to survey her surroundings. It is early evening, stray sunlight from the recently set sun still provides some faint illumination.

Sandra sits on her front step and starts touching herself. Part of me is screaming, "go inside to do that." Another part of me is overcome with arousal. Guess which part has control over my right hand. I start vigorously rubbing my clit. Then the story takes a wild turn. As Sandra's orgasm approaches, she hears a voice to her right. Her neighbor is standing there, watching her. Instead of stopping, Sandra just looks him directly in the eye and keeps touching herself.

This is it. I close my eyes and imagine pleasuring myself just outside my front door. In my head, I hear a male voice, "Caitlyn, what are you doing?" It is my neighbor and classmate, Michael. In real life, my hand moves faster and faster as imaginary Michael watches me. Then I hear another voice. "Caitlyn!" It takes me a second, but I realize that isn't just in my head. "Caitlyn, can you come help me with something?" It is my mom, calling to me from downstairs again. I didn't even hear her return, I was so caught up in my pleasure. I am so close, I consider just finishing the job until I hear her calling to me again. "Caitlyn, are you there?"

"Yes, mom, be there in a minute," I manage to call out. I swing my feet over the side of the bed and stand up. I need a moment to steady myself, my legs are still a little wobbly. I take the shirt off the desk chair and throw it on. I am about to search the room for the rest of the clothes I had haphazardly tossed away when I catch a glimpse of my reflection in the full length mirror in my room. The shirt is just long enough to keep me covered. I look the same as I did earlier this morning, though maybe a little out of breath. Maybe this is enough.

I pull open my door and walk out into the hallway. This immediately feels strange, but I keep walking towards the stairs and start descending. My mind is swirling with conflicting thoughts. Should I go back and put on something more decent? I think I would if I was in a normal state of mind, but half my brain was still horny. "This will just take a minute and then you can run back upstairs and finish," I told myself as I reached the bottom of the stairs.

"There you are. Come out here, I need help with the pool." My mother is standing in the open sliding glass door before turning to walk out of sight to the side of the house. I have to go outside? We have a fence around our yard, but that is still risky. I am about to turn to go back upstairs when my inner voice interrupts. "No one will see you except your mom who thinks you are fully clothed. And the faster you do this, the sooner you cum." I walk toward the open door and step out into the sunlight.

"SURPRISE!" I nearly jump out of my skin when I hear a chorus of voices greeting me. I look to the left and my mother is standing holding a cake with a dozen of my friends standing behind her.

I look at my friend Jess who has a big smile on her face. At least she does for a second before her smile is replaced by a concerned look. Next to her is Tricia, another close friend of mine. Her face looks more intrigued. Have I been caught? Does this shirt not hide as much as I thought?

My panic worsens when I notice another one of the attendees of this surprise party. Michael, my neighbor whom I have known since we were kids, is standing there looking at me. I want to turn heel and run back inside until my mom says, "There she is! Happy birthday, hun. Now come here and blow out the candles." She sets the cake down at the end of the picnic table, eighteen candles already lit.

I don't want to draw more attention to my state of dress, but this is too much. "I should go get dressed, uh, more appropriately for a party." Before I can escape, my mom says, "In a second, just come blow out the candles first. I don't want the wax to melt onto the cake."

Trying to act natural, I carefully walk toward the group as to not flip up the front of my shirt. I take my place in front of the cake while everyone gathers around the table. It is only now that I am realizing that this table is only around belly button height. I will need to bend down to blow out the candles. I slowly start to bend my torso forward when I feel the back of my shirt ride up my ass. I am glad no one is swimming in the pool behind me right now. They would be getting a hell of a view. I speed up and quickly drop my face down, blow with all my might, and stand straight back up. Everyone starts clapping. No one seems to realize I just flashed my bare backside. That is until I look to my left and see my friend Jess standing right next to me. Her eyes are wide open and she looks frozen in place. After a second, she recovers and tries to put on a neutral expression, but I can tell she is still stunned.

This was immensely embarrassing, but I know I didn't have to worry about Jess blabbing about this to anyone. I didn't trust anyone else in the entire world more than her. This was now our secret. I hope it stays that way.

I take a quick look at Tricia to see if she is reacting. I love Trish, but she is a different story than Jess. If she knew I was naked under this shirt, she would declare it from the rooftops. Or she would do everything she could to expose me. Luckily, she didn't seem to notice my accidental exposure, but I am still worried she suspects something is up.

"Okay everyone, line up for a group picture." My mom was now standing on the other side of the table holding her smart phone like a camera. Before I can move, my friends line up on each side of me with me smack dab in the middle. Jess is standing next to me on the left and I only now see who is standing to my right. Michael moves just a few inches away from me, completely unaware that he is standing next to an almost naked girl.

"Can you all take one step backward and then squeeze in nice and tight so everyone fits in the frame." My mom is standing with her back up against the side of the house, unable to back up any further. We all take a step backward, careful not to get too close to the edge of the pool behind us. Then I feel Jess and Michael press their shoulders against mine. I feel Jess place her hand in the middle of my back before Michael's hand presses gently on my lower back. With their hands on my back, the shirt begins to ride up in the back again. A light breeze is noticeable at the very bottom of my cheeks. I feel a tingling between my legs.

My mother is holding her phone in front of her face, trying to line up the shot. I am trying my best to just smile and look normal and not like the horny mess I am. That gets harder when my mom looks up from her screen and announces, "And don't worry, I will make sure I send everyone a copy later." All of my friends are going to have a picture of me wearing nothing but a shirt, teetering on the edge of embarrassment and arousal. I feel a drop of moisture running down the inside of my thigh as my mom starts counting down. "3, 2, 1, say cheese!"

As the flash goes off, I can feel a wave of pleasure building. I desperately want release, but not here, not now. My legs start to tremble when I feel my friends' hands pull away from my back. It becomes apparent how much I was relying on them for balance as I start to stumble backwards. Suddenly, my body is surrounded by cool water as I fall ass first into the pool, jolting me out of my impending orgasm.

Regaining my composure, I resurface at the edge of the pool, clutching to the side with both hands. I look up to see my friends standing over me, turning around to look at the clumsy birthday girl. I can hear my mom laughing from behind them. My mom manages to stop cackling long enough to ask, "Sorry, I should ask if you are okay."

Define okay. I didn't get hurt, but I have been on the brink of a much-needed climax multiple times and have been denied. Instead of saying all of that, I just say, "yes. I could use a towel, though."

"Sure thing, hun." My mom responds, still trying to fight back chuckles. "You, take my phone. I put it in video mode just in case Caitlyn does anything else worth recording." Then I hear my mother's laughter fade away as she heads back inside the house, apparently having handed over the role of camera person to one of my friends.

The silence is deafening as I look up at all my friends, all staring downward at me. I pull myself even closer to the edge of the pool, hoping to shield my body from their view. I can feel the bottom of the shirt floating up under the water, completely uncovering my pussy and ass. I am pretty sure they cannot see it, but I sure feel it.

At the end of the line of onlookers, I notice Tricia is the only one not looking at me. Instead, she is looking at the screen of my mom's phone which she is pointing directly at me. Tricia herself decides to break the silence. "Caitlyn, are you wearing a bra?"

I may have my private bits hidden, but my shoulders are visible above the water. With my shirt completely soaked, it is obvious there are no straps underneath. The gears in my head are turning, trying to come up with an answer, but I know whatever lie I tell will unravel the moment I get out of this pool. Rather than responding to Tricia's question, I let out a soft moan.

Without thinking about it, my right hand had let go of the edge of the pool and snuck its way down between my legs where it was now playing with my pussy lips under the water. All eyes are glued to me as I try to regain control, but my hand just continues manipulating my delicate folds. My hand freezes when I hear, "One towel coming right up." My mom had returned and the writing was on the wall. I was going to have to get out of this pool in my now wet and transparent shirt. A look of panic is etched across my face.

Then Jess spoke up. "Actually, we decided to swim for a bit before having cake." She reaches into the pocket of her shorts and pulls out her phone and keys. She sets she on the table before taking a running leap into the pool, still wearing all her clothes. She surfaces and looks back at the rest of the group. "Isn't that right?"

It takes a second before the others clue in, but then they follow suit, setting their belongings on the table before joining us in the water. Only Tricia stays dry as she remains on the pool deck.

"Looks like this is turning into one fun party." My mom comments. "I will just leave the towel here and you all can come in and have cake whenever you are ready."

As I watch her retrieve the cake and carry it inside, I feel relief that I didn't need to expose myself in front of my mom. She isn't the strictest parent, but she still wouldn't like me running around nearly naked.

"Caitlyn." I hear a voice from behind me. I turn around and see everyone now looking at me, this time without the edge of the pool to keep my body concealed. I instinctively reach down with both hands to pull down the bottom of the shirt to cover my pussy, which has the side effect of pulling the material tighter across my chest. I glance down quickly to see that my nipples are visible, clear as day, and are poking out like to pencil erasers.

"Why are you wearing just a shirt?" Michael asks, sounding equal amounts concerned and intrigued.

Without thinking, I blurt out, "because I was naked in my room before I came out here," before realizing that I did not need to share that information, but my mind is barely functioning now.

Michael continues his line of questioning. "Why were you naked?"

This time, I try to be more tactful about how I respond. I could say 'I just got out of the shower' or 'I was trying on new clothes'. Heck, even saying 'I sleep naked' would be less embarrassing than the truth. The truth being that I was imagining myself masturbating outside in front of you and was on the verge of a earth-shattering orgasm which I still desperately need. As I recall everything that has happened, I let go of the shirt and return my right hand to my clit, which is aching for attention. Rather than offering one of the lies I came up with, I gently squeak out, "Because I was masturbating."

In an amused tone, Jess replies, "was?"

Looking at my audience in front of me, I am overcome with the desire to climax. I pull myself out of the pool and sit with my feet dangling in the water. The wet shirt is clinging to my chest, the bottom bunched up around my waist so that my pussy is totally exposed and my bare ass is on the edge of the pool. My right hand gets back to work rhythmically rubbing my lips as my left hand rubs my nipples through the transparent shirt.

Out of my periphery, I see Tricia taking a few steps forward, trying to get a better angle to record my self-pleasure. Both hands shoot to the bottom of my shirt, this time not for cover, but to hastily pull the shirt up and over my head. I drop the shirt next to me and continue playing with my clit and my nipples, now fully naked and fully beyond the point of return.

I feel the first orgasm hits me like a wave. I lean back and lie down with my legs spread wide, giving my enthralled crowd the most personal view imaginable. Another orgasm overtakes me as I see Tricia holding the phone directly above me, capturing every detail of my unrestrained climax. A series of louder and louder moans punctuate the most intense sexual release of my life.
