Mistress Risa, the epitome of Japanese femdom, takes her slender submissive, Oono, through an anal expansion session. With a gleaming dildo in hand, she commands him to ass up, displaying his tight hole. Gently, yet firmly, she pushes the dildo into his virgin ass, watching it stretch and expand with each thrust. Oono whimpers, but Risa's stern look silences him, as she continues to push, expanding his limits.
