The stiff end gets inserted into the vagina and the flexible end lies on the clitoris or gets inserted into the anus. The man can insert it so that the stiff end is inside the anus and the flexible end can stimulate the perineum – this means that this vibrator is perfect for homosexual couples as well. The penis can just slide in enjoying the dots and vibration as it does so. The two strong motors have 10 vibration modes that intensely stimulate both partners. Includes a USB cable. Complete length 13.1 cm, insertion length of the long end 11 cm, insertion length of the short end 6 cm, O 2.8 cm. Silicone, PU.
