Powerful pumping and suction impulses create an automatic, rhythmic up-and-down motion of the flexible soft sleeve on the penis, further enhanced by the integrated pleasure ring. The stimulation is individually adjustable: 5 intensity levels and 5 speeds provide 25 different variations. The suction impulses per minute range from 42 in level 1 to 109 in level 5. At the same time, the suction power increases from 16 W to 30 W. Simply apply plenty of water-based lubricant and insert the penis halfway into the flexible, pleasantly soft sleeve, adjust the desired intensity and speed, and enjoy.
