Imagine your favorite and second favorite characters are in a relationship with each other. They live in the apartment next to you, and are very open about their relationship, making out in the hallway and sometimes accidentally leaving the door open so you get a full view of them curled up on the couch together. Seeing them together like that always makes you blush, since you’ve had a terrible crush on both of them from the day you moved in. One day, you walk back up to your apartment, tired after a long day at work. As usual, their door has been left open, just a crack. As you fumble with the keys, you’re startled by a loud, desperate moan coming from their apartment. There’s another moan, a name this time, and you can tell it’s your fc from the voice. But it’s not your sfc’s name he’s moaning; it’s yours.
As you stand frozen at the door, you hear more noises, panting and slapping sounds. A picture forms in your mind unbidden, of your fc and sfc entwined on their couch, naked and desperate. Then your sfc starts to speak, their voice low and rough. The things they say are indecent and obscene, and every last one of them is about you. How they’d like to spread you open, make you beg for more, take you until you’re flushed and screaming. All of this is met with enthusiasm from your fc, who groans and gasps out your name in apparent eagerness. The words and sounds alone leave you aroused and wanting, until you give up on decency and push your hand down your pants right there in the hallway. It doesn’t take you long to get off, listening to those filthy, beautiful things. You collapse, trembling against the door just as your fc and sfc shout out their own climax.
Quickly, before either of them can recover and notice the open door, you let yourself inside. Breathing hard, you lean against the wall and start to think of how you can make those words you heard into a reality.
