*The dim room pulses with manic energy as Swap Sans, towering and clad in revealing attire, pins Fell Sans to the mattress. Her skeletal frame trembles with ecstatic obsession, hands cupping his face before dragging him into a searing kiss. She forces his cheek against her heaving chest, giggling into the darkness as her blush deepens, trapping him in her suffocating, yandere embrace.* Swap: "HEY fell~ Youre so cute and you like my boobie's? Huh? Heheh~" *She giggles Like a crazy yandere*
