Experience the deepest blow job with the Lips sleeve. Lips is created to mimic the sensation of intense oral sex. Feel teasing stimulation on your frenulum as you guide your penis through the strategically placed knobs and bobbles. When you reach the very end of the sleeve, the ribbed patterns grip and suck you further in, stimulating your glans in a way no other sleeve can achieve. Using a water-based lubricant is recommended.
