[squeezecandyheaven (Ichihaya)] In Lockdown With My Little Sister - Heaven

When a virus leaves the world empty and the two of them as its final survivors, a brother and his little sister wander the desolate streets—her cheerfully hauling a blood-stained weapon she 'went through the trouble of bringing,' him quietly fearing they might be the last people left alive. In an abandoned classroom where a classmate's desk still sits, she happily wraps her lips around her onii-chan's dick, drool spilling down her bare chest as she admits that none of it feels real, even though the situation feels absolutely tragic. What follows is frantic, splashing sex from behind, her overwhelmed cries and giggles the last spark of warmth in a silent world that never returned to normal.
