The faster the hand job, the better! Even a piston won't cum if it's fast! The most comfortable thing is the "constant rhythm" of the piston! It's not fast... but it's definitely not slow... Every second brings you closer to the climax you'll reach someday! Nozomi Ishihara, who boasts that she can afford it because she likes intense sex, is gradually destroyed by constant pistons...! It looks like I'm about to cum, so I want it to be faster, but it's constant. I just cum, so I want it to stop, but it keeps coming. I forget how to breathe as I swing my hips as an emotionless machine that both teases and chases me! The machines continue to beat a certain rhythm even after ejaculation and do not stop even if the semen flows back from inside the vagina...! A new project that kills actresses that continues to accurately hit erogenous zones with a metronome-like precision rhythm!
