Reminds me of my street thug days back in Russia, early 2000's. I saw this fat man in an outdoor cafe with his wallet and laptop right on the table. I knew it would be an easy score, so I casually walked up to him. Recognizing the threat, he gently touched my bottom. Surprisingly, I stopped mid-step unable to move, but my already semi erection became rock hard. My eyes widened as I looked down upon him, the bastard was smirking! His other hand then gently tapped my left knee, and I orgasmed about a bucket load right then and there. After the climax I fell into his lap, exhausted. As I looked up at him, he chuckled and said, "looks like I found my next student."
