Found a (very nsfw!) post about bratty!sub Ciar who is in a poly relationship with Mekhin and Menthus in my drafts and thought I'd share in case anyone wanted some inspiration:
My bratty sub!Ciar dreams involve Ciar tied up with black silk pieces of cloth, spread-eagled on the bed while Mekhin climbs onto his dick and sinks down slooooowwwwly with a gentle smile on his face. Ciar is not allowed to move, and is not afraid to vocalise just how upset he is about it, even thoug he knows nothing he says is going to make Mekhin move any faster because Menthus is the one giving the orders.
Menthus runs his fingers through Ciar's hair and then tells Mekhin to begin moving as he wraps his other hand around Ciar's throat. Every time Ciar's hips kick up helplessly in pleasure, Mekhin stops moving while Menthus squeezes until Ciar is gasping for oxygen he doesn't need, pleas tripping over his lips. Methus turns his focus to Ciar's nipples, pinching them into painful peaks, and only when Ciar becomes a bumbling mess does Menthus allow Mekhin to begin moving at a pace set to send them both over the edge. Even so, neither of them cums until Menthus gives them permission because all they want is to be good boys for their Dom.
In the aftermath, both Ciar and Mekhin have their heads in Menthus' lap as he pats their heads, telling them what a wonderful job they did. Mekhin smiles, leans over and presses soft kitten kisses to Ciar's temple as Ciar basks in the attention and lets his mind go blissfully blank. It's the only peace he understands, the only place he feels is truly home.
