I want a rhythm that's sometimes slow and sometimes fast! A consistent rhythm lets me disrupt the friction, immersing me in blissful hip-twisting movements. (Arai Rima DASS-284)

Hand techniques can be fast, but not the faster the better! Thrusting can be fast, but not the faster the better! The most pleasurable is thrusting at a certain speed! Arai Rima is caught in an endless cycle of orgasms. (Any faster and my brain will break down.) Slowly, slowly, then suddenly the rhythm changes! The high-speed, relentless thrusting leaves her mind blank. Her vagina has reached its limit. Will both of us feel pleasure in a swaying, thrusting riding position? Ejaculate inside. Finally, pregnancy is confirmed. More than anything, she wants to shatter her vagina.
