Romantic Fandom sex

So I'm looking for a Fandom erp!
More focused on romance fluff and stuff like that.
I'm a sub
A yaoi erp.
I like big replies.
A oc x character erp.

So the erp can be either in mha,dsmp,or black butler.

The idea could have been either about a character that have been hiding the fact that they were not a Human all that time and gets found out,or either that they used to be a human a long time ago.

Or simply that they actually recently became something not that human and are trying to hide this away but it's it's question of time until that gets to be found out.

Idea for mha:
He have been acting strangely lately since their previous encounter with the villains,his behavior simply changed,he was always a nice and kind person but something feels off about him,and he(oc) have been trying to avoid his strange urges and tendencies but he hardly can contain himself,he simply couldn't resist the temptation.

Dsmp:
He was the kind of person that tried to make people happy,he was smart and very wise,he was a good person in general but in the end a self sacrificing bastard,seen to have a good kind of affection towards the minors but something felt off about him.
And he does not want to be found out,but what happen after those years that he gets found out by the person that he least expected.

Black butler: the earl that wrote a best seller book and ascended to his new title simply stopped attending those encounters and parties,he was a kind person,patient but could be serious and strict when needed.

Species that could appear: siren(merman),elytran(bird peep with bird feet and feathered corners in the face,or even a incubus.

So what I like: power botton,creampie,first time,semi slow burn,sex with feelings,instincts,French kissing,that the dominant side also feels pleasure.

What I do not like: tasting each other liquids,any kind of disgusting kink,sexual toys,hyper,out of character,licking armpit,sniffing intimate body part,bdsm,no con.
