My daughter and I didn't even bother with the main dance. We went straight to the one that had flashing lights, blared techno music and gave out little blue pills like candy. It was clear what my daughter wanted, and she was gonna get it. Downing a few blue pills off the bat my daughter gyrated her hips to the music while brushing up against my crotch. The pills worked fasted that I anticipated, I was at full mast in less than 30 seconds! Shit, where did the principal get those?! My daughter's ass continued to gyrate, brushing up against my fully erect dick. The song really picked up, my daughter went with the song and shook her ass at mock speed. Shit am I gonna...cum. I just came in my pants. Pump after pump my daughter continued to twerk on my dick oblivious to what just happened. A few girls saw, some laughed, some were shocked. I leaned closer to my daughter's ear and whispered "I just came in my pants." She stoped her erotic motions to look at the big wet spot on my pants. "Wow...I know I'm good at twerking.....but I'm this good?" She said. "Well come on. Take it off. You can't walk around in those anymore. I guess you'll just have to rock out with your cock out. *laughs*" She added.
