Out-of-Turn Master w/ trifle

If I play an Out-of-Turn Master card that has triffle, do I then get to play a master card when it comes to my turn again?

Yes.

For example, if you play a Wash (that isn't cancelled) you will still have a master phase action.

Note that if you play a trifle in that master phase, you do not get to play another master, as you cannot recieve the trifle benefit twice.

Trifle: Some master cards are identified as trifles. When a Methuselah plays a trifle (and it isn't canceled), she gains an additional master phase action. For an out-of-turn trifle, she gains a master phase action in her next master phase. A Methuselah can gain only one master phase action from trifles in a given master phase; others act like regular master cards.
