Chapter 8: After Class

When the class was over we hung around until Mark came out. Robin winked at him and I gave him a sexy smile. Mark blushed instantly before he could look away. He had such a guilty look on his face we knew he must have been watching us. He hurried out of the room but Robin went back into Mark’s private little lab room. I followed her wondering what she as going to do. When I entered she was looking though the trash can.

“What in the world are you looking for?” I asked.

‘I know it’s in here,” Robin replied as she rummaged through the paper. Suddenly she grabbed something and cried out, “Ah ha! I knew it!”

I looked at what she was holding - it was just a wadded up piece of paper towel from the dispenser next to the sink.

“What in the world are you talking about Robin?” I asked, totally mystified.

Robin sniffed the paper towel and handed it to me. Immediately I could see it was stained with a creamy, faintly yellow substance and when I smelled it I knew exactly what it was. After all, I’d smelled and tasted it dozens of times in the past, not to mention just this morning. Someone had recently cum in the paper towel and I knew it could’ve been only one person - Mark. We both looked at each other and broke out laughing.

“Oh my god Kelly,” Robin exclaimed, “Well, I don’t blame the little pervert for jerking off. Even I couldn’t believe the show you were putting on! Damn girl, I never dreamed you would get so carried away you little slut!”

Coming from Robin, that was quite a compliment so I just smiled and looked behind us. The classroom had emptied and nobody was in sight. I reached up to her and planted a kiss on her mouth. She never hesitated, responding back to me with a passion and lust that confirmed what I’d suspected earlier.

We held it for a few seconds and then released, smiling at each other as we both seemed to be a bit surprised at ourselves. Robin gave me a wink saying, “You know Kelly, you’re one hot little bitch. You wouldn’t be interested in getting together sometime, would you?”

From the sly look on her face and the way she teasingly licked her lips, I knew she wasn’t interested in just chatting! I’d never done anything with another girl and so I panicked just a bit.

“Ummmmm ... thanks Robin and I appreciate it but no thanks. So ... are you going to the restroom to put on your panties?” I asked, looking to change the subject

Robin laughed saying, “Not today, why do you think I only pick classes with male teachers? Besides, you’ve got me so horny now I’m going to have to take it out on a few of the poor guys today or I may just burst!”

We left the classroom and went our separate ways. I decided the hell with it, why not leave my panties off? To make sure I didn’t chicken out I dumped them into a waste can along the way. My heart skipped a beat as I thought about what would happen if someone saw my bare ass but just the same I felt that familiar twinge in my pussy I get whenever I’m doing something naughty.

It had been a lot of fun and even though I doubted we would ever do such a thing again, I would never look at chemistry class the same way again!

I doubted Mark would either!
