First take on the servok fuck machine. Above level 50, the device is best if you live alone or don t care about the neighbors knowing. It isn t that The servo engine gets loud, I mean it does, but the movement of the machine is raucous as it bucks like a wild stallion and fucks like a wild stalion. Other fuck machines due that. What s special about The servo engine is diversity and dynamics: the ability to change the depth on the fly in the middle of the session is great! You can slowly step in a toy deeper and deeper to assist with penetration. Stretch in advance though - proper warmups for proper play.
