Achieving the sex positions you want while standing in the shower can be tricky. However, the Sex In The Shower Locking Suction Foot Rest makes them a whole lot easier.
On the back of this foot rest is a strong suction cup. To activate it, lift up the leaver on the bottom, place the suction cup onto a hard, flat surface (the shower wall) and then clip the leaver back down to create a strong suction. Now sex in the shower becomes a cinch.
Please note, this is designed just to be a foot rest. Trying to put total weight on it may cause the rest to slip and the suction to fail.
Couple this with the Sex In The Shower Locking Handle for a real stable ride!
