Both
She has what I refer to as her bull, but she calls him her boyfriend. He is single, late 30s and lives 6 miles from us, so he is here a lot.
She also has three local regulars that are married but their wives refuse them sex, so Lisa is their "go-to pussy". No relationship with them per se other than her being available when they need a willing pussy to unload in.
She is also 100% open to random hookups whenever the chance presents itself, which is pretty often considering we live in such a small community.
