You do understand that power bottom means someone who only bottoms, not a powerful person right??
Dominant Omega then ?
No, since that is a description for a secondary gender, so it would be confusing. That in this context fits only truely for Dane.
Strong omega, protective omega is probably better?
In this relationship he is a bottom, so I will call him a "power bottom". Trust me, it's not that deep.
Love to see power bottoms
