Enjoy intense blowjob-like simulation with the incredible Suck N Stroke Head Pump. This easy-to-use tip teaser creates a powerful suction action that stimulates the sensitive nerve endings underneath and around your penis head. With each squeeze of the medical-style pump ball, the soft rubber sleeve clings to your manhood and slides up and down with each pump.
