To get into this sex position, both partners should step into the shower. The receiving partner stands in front of the penetrating partner and pushes their butt into the penetrating partner. The receiving partner then bends over and grips onto something for stability while the penetrating partner can slide inside
More About Slippery Rear Sex Position
The Slippery Rear lets couples explore the erotic atmosphere of shower sex - even if you don't have a lot of space to spare in your bathroom. As the sex position is standing, variations of this sex position can be done even if the receiver can't bend over (like in a small, box-style upright shower). A foot pedestal is ideal for bigger bodies. By placing your foot up, you will allow more access to the vulva or anus in a "tight squeeze" shower.
As in all aquatic sex positions, make sure you focus on safety and stability when undertaking the Slippery Rear sex position. While the receiver shown in the illustration is balancing on their tippy toes, we highly, highly recommend you stand flat-footed with a firm grip on a stabilizing aspect of your shower. Non-slip mats can be helpful.
We also recommend finding a surface for the receiving partner to grip onto. While the illustration shows a suction cup shower handle, we recommend using anything that's available to you. This might be as simple as a wall that the receiver can brace their hands on. It also could look like gripping onto the seat of a weight-bearing shower chair - or placing their hands on a built-in seat of the shower.
