quid pro quo

(from Latin. translates to something for something) an exchange of consideration. While the term, quid pro quo is often used in reference to closed-door, political deals, there is really nothing ominous in the term itself. It simply refers to an agreement where one thing is exchanged for another.

While Fergus is a huge hockey fan, his wife, Fiona, is bored by the sport. On the other hand Fergus detests the true-crime dramas that provide a staple of Fiona's existence. The couple strikes a bargain, quid pro quo: Fergus will limit his time watching hockey if Fiona will do the same with true-crime drama.
