Seiondo (sigh-ON-doh), n.
An intentional environment of tranquility, opulence, and service.
You've wanted it forever. Even before you had a name for it.
You've craved it. And now you've found out that this is really a thing.
Whatever name you learned it by:
- Power exchange, or "total" power exchange (TPE)
- Authority exchange
- Master/slave
- Dominant/submissive
The fact is, yes: people actually live this lifestyle all over the world, in committed, authentic and healthy 24/7 relationships.
Who we are
Hi, we are Master Koi, slave lexi and slave lessli.

We're living proof that you can actually live this lifestyle and have healthy, positive relationships.
Whether you identify as a Master or a slave, or you're just uncertain, this site will help you explore the duality and the "balanced but not equal" world of authority exchange dynamics.
Through our years of study and practice in relationships, authority exchange, psychology and interpersonal dynamics, we have developed an approach to this lifestyle built on a commitment to communication, support, compassion, acceptance and love.
We call it Seiondo.
Seiondo loosely translates as "the way of harmony of the spirit." It is a deliberate, chosen path of tranquility, found through the disciplines of control and surrender.
Walking the path of Seiondo means embracing the duality of our chosen lifestyle. It means living committed to the disciplines needed to keep the balance on our own side of the slash.
So… what's next?

Where the name Seiondo comes from, what "the way of harmony of the spirit" means, and how a Denver Master/slave household came to live it.
- Vulnerability and Risk
Why "casual M/s" is, to some, an oxymoron: the emotional risk of surrender, and why deep vulnerability belongs only in carefully vetted partnerships.
