In a dimly lit room, a nervous cuckold awaits Mistress Sana's commands. He knows the drill, but tonight's performance is different. She's introduced a new toy, a thick, black strapon. His heart races as she orders him to strip, his cock hardening despite his humiliation. She lubes up the toy, her smirk evident even over the audio. "Beg for it," she purrs. He hesitates, then starts, his voice barely a whisper. She growls, "Louder," and he obeys, his pleas for anal penetration filling the room. She laughs, enjoying his discomfort, and then, without warning, she pushes the toy into his ass. He gasps, then moans, his cock leaking pre-cum as she fucks him hard, his begging turning to cries of pleasure.
