I did it in the shower last night.My bf is 6"4 im 5"6 so we can face each other because of the height difference.I just lean my shoulders against the wall, lift the left leg over his shoulder while he holds my leg and bum for support then pumps away its all good i like that position.We couldnt do that in our last place because the shower was too small it had to be doggy.Shower sex is good i like it.Bath sex is good too but can be squashy lol
