I am a student, and now my erection is 16cm long and a little tilted to the right and upward. I once went to live with a good friend for one night. When we were taking a bath in the bathroom, we touched each other’s penis. He ejaculated first. I boldly inserted it into his ass ( there was no venereal disease ), which was my first time. This is really cool! He clamped his buttocks tightly and soon I ejaculated.
