[Akatsuki Katsuie no Circle (Akatsuki Katsuie)] Welcome to the 6th Floor (Overlord)

Aura and Mare, the twin elven servants of Nazarick, find themselves flustered and flushed as they take turns servicing their monstrous master's throbbing member, their competitive sibling rivalry turning into a heated contest to see who can make him cum harder. Aura boasts that her handjob skills will outshine her brother's, prompting the shy, dark-skinned twin to nervously try his tongue against the pulsing shaft, only to discover the lewd "semen-strength" far surpasses anything he imagined. The scene escalates into an eager, dripping contest of tongues and fingers until the overpowered lord erupts, leaving both twins trembling with questions about what exactly they just swallowed.
