Anime bxb erp (romance)

Hello I'm looking to do a yaoi maybe genderbend yaoi romance erp!
Irl Gender doesn't matter.
I'm just fine with big replies or long term erp with fluff mixed with romance. And maybe some angst.

I'm focusing on character x oc.
I'm using a oc but if you want to use a oc as well we can do the oc x oc crush and then your turn u be like oc x oc crush.
By us role-playing our ocs and our ocs crush.

It's more focused on fandoms really.
You can decide what Fandom we do and that's it!

Fandom that I'm fine:

Owari no seraph (seraph of the end)
Black butler (kuroshitsuji)
Dsmp(dream smp)
Mha (my hero academia)

Idea:
So the general plot was about a character that is a human or used to be a human but is not as human s they though they were.

A peep from another dimension who got stuck on this dimension, hiding those facts and everything else away,simply a person that maintains a certain amount of calmness and is kind but actually they are pretty shy,a person who never got to have sex, or either to kiss someone or for someone to confess to then.

A person with self esteem problem that have found out that they aren't that human and now is on the run to hide this away but what happens when their crush gets suspicious or simply worried and gets to go to see if they are ok and find this out.

What the oc could become:
Incubus
Siren(merman like thing)
Bird like hybrid(with wings,bird like legs and stuff like that)

What I'm fine with:

Smut with feelings,creampie,first time,heat(mating cycle),transformation,genderbend,egg laying,both sides even the dominant one feeling pleasure,aphrodisiac,unattractive beauty.

Not OK with:
Out of character,any kind of disgusting kink,smelling intimate body part,armpit licking,any kind of inc€st,any kind of sl@ve,vore,gore,dirty talk with cussing,bdsm,humiliation,choking,blood,pet play,abuse,food play,foot play.
