All of the guests. They carpooled

"H-hey everyone..." I tried to **** a smile, as a group of very clothed girls entered the house, rattled down their greetings and birthday wishes, and each, after noticing my nudity with a dumbfounded expression, went in for an awkward hug. As they poured in, six of them in total, two of which I didn't know, they began whispering amongst themselves; naturally, as you didn't usually encounter a birthday girl in on her birthday in her birthday suit! I didn't have the focus to listen to what they were saying, but I was sure I heard one of them remarking something about my boobs. My arm was still tightly pressed against them, but me being a D-cup, plenty of them spilled out and there was nothing I could do against that. My face practically burned, I was blushing so hard!

And that was when the boys came in. The first one I recognized as Joey, from book club. I invitied him specifically because I regarded him as a very gentle, polite guy, but... okay, I can't blame him for checking out every centimeter of my exposed skin. He would have totally had the mind to look away if he could have expected it. But in this situation, suddenly being confronted with a beautiful naked teenage body, a young man just couldn't help but ogle.

"...hey there, Alice. Happy birthday! You're, erm... looking good! Very good." He stumbled over his words, and his gaze seemed fixated on my chest. Very fixated on my right breast specifically, which I was covering with my elbow... though in that moment, a breeze from outside tickled my nipple. My very exposed nipple! My deep blush renewed, I shifted my arm to cover myself again. The party hadn't even started, and had seen the top of my breast...

Thoroughly embarrassed, I greeted the rest of them, seven in total, every one letting their gaze wander. The last one, one of the two unknown tag-alongs, even went for a hug, and when he pulled his arms away, his hands brushed against the sides of my boobs, making me gasp! Had he done that on purpose?

When everyone had gathered inside and the door was closed, I approached my mom, using awkward side-steps so I didn't flash my ass to the guests, who were talking noisily amongst themselves.

"...you made your point! They've all seen my body, and I'm proud and feel beautiful and all that, but can I please get dressed now...?" I whispered to her. It was supposed to come out as an annoyed hiss, but I was too humbled to pull it off. Didn't matter anyway; she ignored me. Climbing up a few stairs so that everyone could see her, she coughed, drawing the attention of all the guests.

"Hi everyone! Glad you could all make it. My precious daughter Alice here is turning eighteen today, and I'm sure everyone agrees we want to make this day unforgettable."

"Why is she nude? Just tell us already." I didn't know who shouted that out; but it was perfectly valid to be curious. Maybe this would cut my humiliation short. My mom couldn't just have me actually be naked for the whole day, right? That was crazy.

"Glad you asked! It's an old family tradition: celebrating the coming-of-age, and the blossoming of the female body, by staying in the nude for the whole birthday, and depending on circumstances... maybe even longer! And Alice here solemnly promised to honour the tradition, as you can all see. She's pretty nervous right now, but... would you like to say something yourself?"

Suddenly, all eyes were on me. I was in the middle of worrying about these 'circumstances' mom had mentioned, and struggling to find words; I just wanted them to stop staring so I could think for a moment!

"Uhm... yeah, that's what happened... um, thank you for coming everyone... we'll have a great time?"

My awkward stammering was met with cheers and applause. I was showered with admiration for my bravery and compliments about my body. One of the girls I didn't know said: "You know, at first I thought this would be a little boring, but this is wild! I'm glad I came along."

Fuck... I'm in a bind, now... can't talk myself out of this... I still felt extremely embarrassed at being naked in front of a whopping fifteen people, seven of them boys. But at least I could cover myself? I tried to tell myself that I wasn't showing off anything more than I would with a skimpy bikini. As long as I positioned myself carefully and didn't let my hands slip, that would remain true. But could I keep that up for the whole day? It was a long road until midnight.
