#sub!rubedo

those two will be pulling each other's hair i can see it lol

oh poor ruebedo! drowning in your affections that was meant for your albedo. you didn't notice the star gone from his neck, the one you called pretty all the time when you compliment albedo. you approach him from the back with an embrace, nuzzling his hair and asking how his day has been. ruebedo tensed, unsure how to react. shit, it was albedo's lover. he can't be identified, he mustn't. so he tries, tries to act the way he believes albedo would act with you; turning around and hugging you back, burying his head in your chest and you're none the wiser, returning back his affection.

oh, tsk tsk, reader you're meanie! how dare you! you've captured his heart, all the while albedo was gone and he was in his place, he was spoiled with your love. your arm around him as he sits down with you on the couch (i know there's no couch in his lab but bear with me lol) and relaxing by the fire, you playing with his hair occasionally. you tell him about your day, saying how you missed him and wished he was by your side. rubedo was feeling warm, hot. the way you say it, it makes his stomach churn in want. how could albedo keep you from him? the way you caress him, telling him how you love him, makes jealousy burn inside him. he must have you, albedo can't! albedo doesn't deserve you! he's always away doing god knows what but he's here! he'll let you take him, he'll be yours!

so he takes action. he makes the first move, sitting on your lap and wrapping his arms around you and pulling you close, kissing you. you were taken aback at first as your albedo was shy when it comes to being intimate with you but you won't complain, you were excited more than anything, believing your "albedo" wants you.

one things leads to another and now we have ruebedo being fucked sensless on the couch, face buried in the pillow and eyes crossed as your hips thrust in a fast pace. "hghuk—! [name]! slo—slow down! you're gonna make me cum! i'll ohh— i'll cum!", you hips thrust faster, hips snapping against his ass and leaning down his ear, "go on, albedo, cum for me." ruebedo screams, in both frustration and pleasure, cum shooting out and ruining the couch below. as he catches his breath he thinks, he'll make you say his name.

after pulling out, you kiss his temple, praising how good he was for you. you help him lie down in a comfortable position and tell him you'll get him cleaned up. as you prepare a washcloth, you were unaware of the real albedo entering the cave, seeing his doppelgänger lying so comfortably on the couch and seethes. look like there's a pest he needs to take care of.
