This Vibrator Really sucks, the mouth moves, bites, and the tongue vibrates🔥 It imitates the feeling of a real person’s mouth, biting the lips and vibrating tongue against the head🍼 The rhythmic vacuum suction nipples can be adjusted to increase the suction to bring them into contact with the mouth. And helps improve blood circulation, making the breasts look fuller (temporary and will return to normal) The on/off kissing function is very soft silicone.
