Standing in the shower is not the only way to get clean while also getting dirty. If you happen to have a bathtub, you can get naughty in there too.
These 3 positions are perfect for bathtub sex.
Doggie style:
This is one that can work in a tub. She goes down on all fours while he enters her from behind. A narrow tub is certainly no hindrance.
The Squat:
The woman-on-top position where she squats on him might be easier in a tub. She has both sides of the tub to hold on to which might take some weight off her knees.
The Sit ‘n’ Ride:
He can sit and relax in the tub while she lowers herself on him and grinds them both to bliss. The position reduces the likelihood that you will slip.
