Free Rein

A couple decide to open things up, on the record: she goes out with someone else, he knows, and the two of them write the rules before anything happens. No surprise NTR here, just consensual sharing between two people who love each other, tagged honestly so nobody gets ambushed.

The story turns on what gets negotiated beforehand and what gets confessed after. The evening itself matters less than the conversation around it, the boundaries drawn, the things said and the things left unsaid when she comes home.

You play through both sides of that arrangement, from text, shaping the terms of the negotiation and then living with what the night actually does to them. It's short, and it stays sharp rather than sprawling into a dozen branches.
