Can Incestuous Relationships be Monogamous?

I've seen several posts where people mention that they or their partner see other people or have had relationships that didn’t last. However, incestuous relationships can also be monogamous. People can be faithful, committed, and build a mature relationship just like any other couple. Monogamy is a choice based on trust, love, and mutual commitment, regardless of the nature of the relationship. Does anyone here have experience with a monogamous and long-term incestuous relationship?
