The sensation of invading a submissive’s ass with my fist is unparalleled. The way they bend to my will, their body yielding to the intrusion, is incredibly arousing. The warmth of a tight ass surrounding my fist is what directly excites me. Seeing the submissive experience pleasure from the act is insanely sexy. Fisting and using a strapon on a submissive are my most cherished fetishes.
