All the efforts, lead both of you to this, enjoy your new life as one.... which if course can be redo, is a kink to enjoy for fun and not take as a canon, is to have fun and mess up all you want, experiment with other kinks as well, in all just have fun!

The five level is just possessor becoming their host entirely in body mind and soul, both of you reached this level of bond, your host given all and becomes the only one and original and most powerful version of you, teasing in this stage is greater, and is only reached consensually going through-

Be affected by it, if your possessor was more dominant your personality will be altered by it and viceversa, there are no physical changes besides increase in power and size, no doubt at this point you are far powerful than you were originally, you are almost perfect as one.

Fourth level is merging entirely with your host soul, there the trust is absolute, your host mix their will with their possessor and so there is no more fight back, you are one almost totally, your host will deep resides inside your soul and depending on who have stronger will the personality will-

And kinks like macro can come in play which is a fav of mine in this level, in this point both parts are enjoying itselves, both can decide in unison which actions you wanna do, what you wanna try, feel, you are one with your host physically and mentally, and so you bent to the limitations of-

Third level is where things get spicier, now the possessor mix itself into the host soul if the situation is right for it, you both start to think as one being rather than 2 separate entities, but the hist still keeps his individuality as your force of will, the host body also benefits greatly-

That besides the fact how much can the soul merge here increase both parts sensibility, the intimacy grows stronger and the bond gets powerful, enjoyment of other kinks is shared for both which can be anything.

And just as level 1 you both share everything you do, as the bond to the host is stronger so the body can also get bigger, your host powers do also get stronger. A key factor is the mind influence, the one with strongest will is gonna influence more on how they think, how they act together.

Second level is possessing your host soul, at this level the host stays more as a spectator and control over the body is for the possessor, there has to be trust to allow this unless people is going for a take by force route, but is better when is consensual, your host still keeps his will-

Kink in general, as it relaxes your host mind enough to give you free will, other good kinks to mix in this level is teasing, self worship, praising, etc. If both parts are willing to go further this is where we can jump into the second level, as if requieres trust from both parts.

Fight back your possessor, but is all a intimacy moment between both, both share and feel everything and how much control you give in this stage relies in how much are you willing to continue as the host, some kinks may also influence how it goes, we have hypnosis that is a good synergy with this-

For a level 1 possession is our classic, both share the host body, both feel the same feelings, touching, is like your possessor's is cuddling your soul in a warm hug, relaxing your will enough for them to take the control, but in this stage you definitely can share control, or even-

As for the effects on the host, in general not only boost their host strenght but also feelings, ego, etc, i divided the effects and some associated kinks for each level which i think further increases how the bond of the host and possessor works, but you defo make your host more powerful.

How the possessor posses their host is up to choice, phasing through the body is the usual, others try more unhinged ways, i like the concept of slow merge, for the host is chilling but a pleasurable feeling as both involved share the same sensations, but really imagination is your best friend here.

Acts as a Joker kink as it synergizes really well with so many other kinks that makes it really flexible and hot, but is also intimate, it can become a moment of bonding, others prefer more the dominance factor of possession over the host, i'm more fond of the first scenario but i can do both.
