An act between two gay men. It entails the "top" finishing his business, and then allowing the "bottom" to penetrate his partner's anus. Once this partner has "finished" his partner, the original "top" will again penetrate his partner's anus. This can eventually lead to a perpetual sex session. Why Victorian? Courtesy is the policy, once you are done, allow the other to do their business and so on.
