Cincinnati switch over
When one gentleman is performing doggy style sexing whilst another gentleman is receiving felatio from the same female participant the Cincinnati switch occurs when the men trade places, the gentleman in the rear simply removes his member and grasps it with his hand thus transferring the remaining excrement the men then perform a high five thus the second man receiving the excrement and using it for lubrication. I give you the Cincinnati switch ;)
