Premium Ride-on Sex Machines

fun & powerful

Using one of our premium ride-on sex machines is an experience from beginning to climax. Whether alone or with a partner they are fun, fulfilling and offers an experience that no other sexual device can match. The machines have independently controllable motors, one to vibrate and one to rotate. These individually controlled motors, along with its ability to be mounted, makes them the most powerful sex toys available.

orgasm training

These sex machines provide varied stimulation and maximum pleasure, with controls that allow you to focus on your gratification. Sexual response and orgasms are learned behavior. With completely controllable stimulation, from gentle to intense, it is possible to unlock your orgasmic potential. Multiple orgasms experienced with these ride-on sex machines translate into increased sexual responsiveness. To learn more, enroll in the RestoreGasm program

When you pick up a sex machine from the Sexology Institute, you'll watch us clean it, we'll show you how to use it, and we'll answer any questions you have. The sex machine will be in a plain roller-wheeled suitcase so that you can transport it easily and inconspicuously. It is easily managed by one person. Pick up is after 3 pm, and it is to be returned before 1 pm on the return date.


A deposit of 50% of the rental fee will hold your date. This deposit is non-refundable. At the time of rental, a $200 security deposit will be charged to your credit card and refunded to you upon return. See rental agreement.


We professionally clean the machine after return and once again at the time of pick-up while you watch. The machines are coated in an antifungal, liquid-proof industrial-grade vinyl that ensures a sanitary surface. We thoroughly clean the entire unit using hospital-grade cleaners and processes, then we rinse it to bring it to institute standards and ensure that it is skin safe. 

You will complete the rental agreement below when you pick up a sex machine.
