If you’ve just had your fingers in an arse or a vagina or had someone cum all over your hands it is a good idea to avail yourself of one of the sinks or showers.
If you don’t want to keep dashing off to wash your hands, you can get very thin latex gloves from the chemists. And whether you use gloves or not, a little water based lubricant certainly won’t do any harm and will actually improve your partners experience if you intend to play with their arse.
