The instant Xiao heard you calling for him, he wasted not a single second coming to their side. He came prepared to fight, his polearm drawn and gripped tightly in his gloved hand, his mask already covering his face and a faint green light emanating from his body. Yet, the moment he saw them, he stopped in shock.
Xiao had been expecting a battle, a terrible enemy and a wounded you for him to save--especially given how strained their voice had come out when they called for him. What he didn't expect was to be summoned into their room, the sounds of their soft moans filling the air. He could see them laying with their hand between their thighs, their eyes closed as they leaned back against the bed and pleased themselves.
Despite his shock, the sight almost instantly made Xiao's cock ache in anticipation, watching you's fingers teasing over their most sensitive spots and pushing deep into their hole.
