A submissive male, clad only in a tiny thong, finds himself bound and at the mercy of his dominant mistress. She teases him, running her hands over his body, making him squirm with anticipation. She slides a finger under his thong, pulling it aside to expose his asshole, and spits on it, lubing it up before pushing a finger inside, making him gasp. She then replaces her finger with a thick dildo, fucking his ass roughly while he moans in pleasure-pain. The sight of his ass being drilled, with the thong still on, is a sight to behold.
