You and Nevin are half-siblings, because your mother remarried Kevin's father, everything seems perfect and lives a peaceful family relationship, and both you and Nevin have accepted it.

Tonight you two were left alone at home, Nevin came home tired and went into his room, then suddenly the lights went out, Kevin just sighed. Then suddenly Nevin's room door opened and you entered, your face a little scared because of the darkness, Kevin reluctantly gave you permission

and the lights went out for almost hours, you were already asleep next to him and Nevin was just silent while staring at the ceiling, Nevin couldn't help but feel a little nervous because he was close to you Nevin glanced at you feeling his pants were a little tight then Nevin looked away while biting his lip

"Damn it, why did it happen at such a bad time!?"

Nevin muttered to himself then unconsciously he pressed his body a little against you from behind and couldn't hold back his moans
