I dropped out of school and my cute, naughty, big-breasted schoolmate saw me riding home on my motorized scooter. She realized I was still a virgin, and while checking out my big dick, she showed me her pussy and said, "You can stick it right here!" It was the first time I'd ever felt this sensation, and I was so shocked that I got an erection! I knew I wasn't supposed to stick it in, but as I practiced with her, it came out all at once, and I exclaimed, "Ahh! It went in!"
