This is extremely, extremely unoriginal.
But I really enjoy the idea of Remus and Janus having some sort of a heat, where their more animalistic traits show through-
Ship: Either Remus x Janus (Demus) or either character x any other character.
Trigger warnings: Smut- possible BDSM or other kinks, completely up to you I'm leaving the prompt open for interpretation
Au: In which Remus and/or Janus is going through heat, and with that, their more animal like habits, as well as physical attributes, show through.
For Remus:
Remus has tentacles that come out as he pleases. They arent needed for the smut portion, but be aware that they are there.
Both he and Janus produce something called an aphrodisiac which helps to increase sex drive in their partner (but of course they ask before using it)
Remus gets carried away very easily, as a top or bottom he prefers to be in control and prefers when whoever he is with is talking to him to keep him grounded.
Janus:
Janus becomes kind of aggressive in heat, but he still makes sure his partner is completely okay.
As a top he prefers to be in complete control, but as a bottom, he just wants his partner to do the work. This mostly applies when he's in heat, when hes not his patterns are pretty different.
Like i said earlier, he also produces an aphrodisiac, his being injected into his partner via fangs
Janus hisses and growls a l o t, and is very vocal
Remember Im uncomfortable topping, you get to choose whether its demus or another ship and which character you are
