It was my Senior year in high school when I finally succumbed to the urge that I had only fantasized when I masturbated. Billy and I were both 18 and he was going to go to college out of town, so it was now or never.
Since my parents wouldn't be home all day, I invited Billy over to my house to do homework together. I wore my short green plaid skirt. The hem just covers my ass cheeks. White cotton knee high socks, white blouse and saddle shoes. Under my blouse a stuffed white bra. My hair was done in short pig tails.
I just finished dressing when the door bell rang. As I walked to the door I was picturing Billy's face when he sees me standing there dressed like I am. I opened the door and wasn't surprised by his reaction. I told him to close his mouth before a bug flew in it and come on in.
After closing the door behind him I walked over to the steps that lead to my bedroom upstairs. I turned to him smile and say follow me. As I walked up the stairs I wiggled my ass from side to side. I also would be up high enough on the stairs so he could get a slight glimpse of my ass cheeks. Billy was in a trance. I suspected his bi-sexuality many years before, but this was confirmed to me when we followed me up the stairs.
By the time we got to my bedroom I was so horny I could hardly contain myself. I told Billy to put his books on my dresser as I walked over to the full length mirror on the other side of the room. I stared into the mirror at the sexy school girl image reflected in it.
I placed my hands on each of my thighs and slowly moved them up lifting my skirt and flashing my hard cock that was temporarily hidden. I could see Billy out of the corner of the mirror staring back at me. I smiled devilishly to myself. As I moved my hands around to my ass and slowly lifted up the skirt to let him get a peek of my butt. "Do you think I'm sexy Billy?", I teasingly asked as I lowered my skirt still looking in the mirror.
"I'll bet you'd like to get out of those clothes", I said to Billy as I continued to pose and play in front of the mirror. I watched intently as Billy took off his clothes. I was breathing so hard that I could hear myself panting.
Now naked Billy began to stroke his cock. I raised the front of my skirt with my left hand and used my right to wrap my fingers around my cock and slowly stroke it up and down. "Come over here Billy", I gasped as I jerked myself. Billy walked up behind me and I turned to him. Our faces inches away from each other. I put my arms around his neck and he puts his hands on my waist. "Kiss me", I whispered to him. We closed our eyes and I felt his lips meet my red painted lips. I feel the tip of his tongue tap my lips and I opened my mouth to let his tongue enter.
