when you orgasm, for some reason keeping semen below a part of the penis regardless of ejaculatory response keeps a penis erect. It is an evolution to keep the erection going via the squeezing method of coitus interuptus. This takes that idea a step forward to tourniquetting the blood into the penis on a permanent basis so that even though his prostate and kewper's gland are going farknuts the penis loses none of its erection and it is effectively at the same time a dom's leash as well as the girl doesn't have to stop having sex in order to keep the guy under control. it is a very effective premature ejaculator training method.
Sorry, can’t do that~♥ We’ve only just begun. Because, the main point is that you begged me to do something about your premature ejaculation. Nn…♥♥ I can’t be with you if we don’t do this training. Hey, you came again as I was saying that, didn’t you~? Fufufu… That was pretty quick, wasn’t it♥? What will you do? Give up and quit already? Hey, don’t make that kind of face♥ …Ye~s, okay! I understand. In that case, we’ll do it this way♪. Now it doesn’t matter how many times you cum. In place of this, my method will properly make you feel good♥ If this method makes me cum… my hand might loosen and let you cum inside me♥♥Ah, hey! You’re gonna cum involuntarily again? Jeez… Can’t be training like this. Hey, c’mon, show some more fighting spirit… Huh? You say you wanna rest for a little bit?
