I have had an absolutely terrible time lately, and I would therefore like to request some (human AU) unrepentant twincest with Matthew and Alfred. They're twins, they don't care, and it turns them on. Or, at the very least, feels right to them.
If author wants, it can be primarily Matthew, who basically ends up persuading a nervous and reluctant Alfred. Jealous, possessive Matthew, Alfred is his, claims him and no one else can touch him. Or they can just both be super into it.
Could be omegaverse (alpha Matthew, omega Alfred) or just regular human AU.
Bonus for a line like " he was fucking/getting fucked by his brother' or "he was about to fuck his twin brother" and the one thinking it being incredibly turned on by it.
