Luna's Birthday

I lay awake at night, unable to sleep, reliving in my mind the latest humiliation Kim put me through, the thought of her being superior and I always being her loser making me unbelievably horny. I toyed with myself to these thoughts until I brought myself to an amazing (though quiet) orgasm. After a few minutes of resting I remembered something... today was my birthday.

It was thursday and both of my parents were working late, so we already decided we were going to celebrate on the weekend. This meant I was free tonight. I immediately began to wonder if Kim maybe had something planned for me; the thought made my loins tingle, and I knew Kim was certainly capable of organizing occasions I will never forget. With that hopeful thought, I finally managed to fall asleep.

Later that day, I was walking down the school corridor, and sure enough, there was Kim waiting for me. She met me with a a wide smile.

"There she is, the birthday girl! Happy birthday Luna!" she greeted me like we were actual friends.

"Oh, hi Kim. Thanks." I responded awkwardly, while trying to avoid eye contact.

"So, listen, I am throwing a get together with some girls today, since my parents are away, and I thought it would also be the perfect opportunity to celebrate your birthday, after all the times I've made you my bitch, it's the least I can do. And no, you don't have a choice. Six o clock sharp I'm picking you up. Be ready." She immediately changed her tone, looking me dead in the eye.

Her commanding me like that made me feel an inch tall. I only managed a silent nod, since I knew that she was aware my appetite for humiliation is so big, I really didn't have a choice. As she walked away, Kim fondled my breasts and slapped my ass, causing me to almost cum on the spot.

At this point, there was no point in pretending. Kim got me naked more than enough times to know that I have very little objection about being her bitch. I anxiously waited for her to come. During the ride there I could already feel my pussy wet just from anticipation. When we arrived, Kim led me to her backyard, where around 20 girls, most of them from our school, were waiting for us.

"So", Kim said while putting her head around my shoulders. "The birthday girl is here. Most of you know Luna primarily for losing to me and 'accidentally' getting naked. So, I propose a game. For anyone who tells a loser story about Luna, our birthday girl loses a piece of clothing, as is only fair." Kim smiled at me with a malicious grinn.

"What do you say Luna, what does the birthday girl really want?"
