Martin, a seasoned submissive, knows his Mistress Dominather's rules all too well. But tonight, the dungeon is empty, save for the two of them, and the temptation is too great. His cock, hard and throbbing, needs release. He starts to wank, slowly at first, then harder, faster, the pleasure building. He's a mess, sweat dripping down his body, his breath coming in ragged gasps. He knows he shouldn't, but he can't stop. Not until Dominather appears, a wicked grin on her face, ready to punish his disobedience in the most pleasurable way.
