I sat there in the bathroom, cursing myself. Why had I gone to my reunion? I had known she would be there- known she would make it hell for me. Don’t get me wrong though, I wasn't a high school loser. I was just enemies with Rebecca.

So, I sat there, crying because she was already making snide comments about my outfit, my job and how I was single, when I heard the door open. I recognised Her voice, she was talking to some guy. Oh god- she was going to shag him here, where I could hear her. I was about to burst out of the cubicle, when I realised I could see them through the side of the door. I couldn't watch surely… but I found myself reaching up my skirt and finding my panties soaking already.

He moved out of sight, and she lay atop the counter, spreading her legs wide to expose her beautiful shaven pussy, already glistening with her juices. She began rolling her clit between her fingers, and I mimicked her. I felt myself clench in anticipation as he leant forward and began to lick up her legs, from her feet to her thighs. She had gorgeous creamy white thighs, and atop them her dripping pussy. How I wanted to go over and lap up her juices myself.

Rebecca started moaning, calling for him to stop teasing her now, he had her so worked up. He slowly trailed his tongue up towards her pussy…tasting her sweet nectar and making her groan in frustration. Suddenly, he slapped her. Straight across her face.

"This is for cheating on me with Robbie!" he screamed, then he stormed out muttering, “Stupid bitch.”

I froze- I had no idea what to do. Part of me hated Rebecca, but most of me wanted to finish what her guy had started. Slowly, I stood up and flushed the chain, making sure Rebecca knew I was there. I hesitantly opened my cubicle door and stepped out to find her sprawled sexily atop the counter right where he had left her.

"You look amazing," I found myself saying, " Have you ever thought about having a girl-on-girl experience?"

I was shocked myself, as before now I had never actually had fun with another girl, but even more so when she replied, "How dare you speak to me like that? I can't believe you have the cheek to talk to someone better than you like that!"

I was speechless, mortified and completely humiliated, until she followed this up with, "Get down on your knees and beg for my forgiveness!"

I thought I knew where this was going, and I liked it. Kneeling down on the cool tile floor, I reached a hand between my thighs and began to stroke my quivering clit. She grabbed my hand and harshly twisted it behind my back. The pain was an incredible turn-on.

"How can I ever make it up to you?" I asked, thinking of a few ways I would like to. Without answering, she seized my hair and pulled my face in to her delicious pussy, leaving me in no doubt. I gently began to tease her, nibbling and sucking on her outer lips. She moaned and gripped my head harder in encouragement. I slowly moved my tongue in and out of her, reveling in the sweet taste of her juices. " More! More!" she cried out. " Fuck me you dirty bitch!"

I responded by moving my tongue in and out of her, faster and faster til I found the speed
