British slang term for "cum on pussy & then re-enter"?

[fonzee]

OK, Great Britain, recently I heard a great british slang phrase that described the act of fucking and then ejaculating on a woman's pussy, and then putting their dick back in to fuck some more. It was a succinct little phrase, more than two words but not more than five. For the life of me I can't remember it and web searches only return the description above but not the quick phrase that is driving me crazy. Englishmen, please help!

P.S. Nothing to do with frosting on the cake or crust on the pie, it was more descriptive than specific. Gahh!!

For years I'm using POST CUM INSERTION or pci as for the name of a subreddit. I find it pretty descriptive.

In the US, there's the term butter churn

Also U.S. - Bust & Thrust which is sorta closer to that forgotten British phrase but not really cuz I DON'T REMEMBER IT but if I ever hear it again it'll be "THAT'S IT!!"
