My erection was triggered by the young student's devilish penis, and my incredible stamina was used in a riding position for continuous unprotected ejaculation. Arai Rima GVH-599

As a tutor, I was assigned to work with Rima-chan, a J-type student who hated studying and spoke with a Kansai dialect. But I eventually fell for her trick! When she subtly made me erect with her underwear, she mocked my penis, saying, "Teacher, even though you talk so well, you still got an erection!" Then she said, "I study when I'm excited," and pushed me into a cowgirl position, saying, "I don't want to study!" My invincible penis didn't stop after ejaculating; in the end, instead of studying, I was endlessly drained of semen by her infinitely stamina-enhancing sex!
