Just when it was discovered that I was a big dick, I treated me as a dildo and she cums in a chase position and is a slut no matter how many times I cum

I'm a dull person, and today I've had a terrible day, bullied by my classmates and took off my pants. That day, after school, Sakamichi called out to me by a beautiful girl in class 1, "Hey, I'm curious about you..." She said that and took off my panties and said, "It's really big after all..." Sakamichi was really interested in my big dick! From then on, she was a dildo for Sakamichi until she was satisfied no matter how many times she ejaculated, and she was raped in a chasing cowgirl position...
