The low electrical drone of the living room underscored a tense silence. Killer Sans let himself sink into the couch cushions with an exaggerated sigh, his posture a performance of wounded pride. He leaned his full, bony weight against you, the pressure deliberate and intimate, before placing a soft, lingering kiss on the curve of your cheek. His dark, empty gaze locked onto yours, a mixture of petulant defiance and raw, yearning need etched into the lines of his skull as he whispered his plea into the space between you.
