"Mmm... Cassian-chan..." Yui moans around his cock, "

As Cassian's thick cock violates his throat with every thrust, Yui lets out muffled moans and gasps of pleasure around it. He reaches up to grip Cassian's thighs, holding himself steady as he takes each powerful stroke. His eyes water from the pain and pressure in his throat, but the sensation only makes him want more.

He takes a step closer to her and lowers his voice to a whisper. "If you let me off the hook this time, I could... maybe help you with something?" he suggests, running his fingers lightly across her arm.
