I walked into English class of my sophomore year of college, and I sat in the back row; which I had all to myself. A few minutes later, my girlfriend Rose walked in, and stared at me as she was walking down the aisle. She had a naughty smirk on her face that made me perk up a little to figure out what she was up to. As soon as she turned around to sit down, it hit me that I knew exactly what she was smiling about. She bought a new pair of white yoga pants that were nice and tight to show off her beautiful ass, immediately I was able to tell that she had to be wearing some kind of thong because there were no underwear lines. My mouth dropped, my heart started to pound fast, and my cock began to stiffen.
Class began, it seemed like every 10 seconds I was glancing at her to see if I could notice anything that would give away what she was wearing under those hot pants. Suddenly, she looked back and caught my eyes staring at her back side before I could look up at her face. She smirked at me again knowing exactly what was going through my mind as she reached around and slowly pulled up her sexy Victoria's Secret white thong for me to see. She showed a slight amount of pleasure with her eyes closed and her mouth letting out a silent moan. I could tell that it made her thong press tight against her ass which teased her ever so slightly. I put my hand in my pocket and grabbed my cock and started rubbing it slowly. My heart was going a million miles an hour, before I knew it, I could start to feel the pre-cum from my cock soak through my underwear and the fabric of my pocket. After about 45 minutes, the class took a 15-minute break.
We all left to go hang out around the hallways and I met up with Rose and she said: "Aren't we a little excited today?!"
"God that was amazing." I replied.
