No, you can't stop yourself from cumming

It's too much. Getting dominated like that, your ass fucked so hard by your Mistress' big cock that seems to hit just the right spots inside you. You try to hold it, of course. You moan loudly, yelling, "Fuck!" as you try to pull yourself up from the table almost reflexively, but that is obviously impossible, the collar holds you against its surface very effectively.

No. There's no way you can resist for long enough even as you feel Mistress Mathilda getting closer and closer to orgasm too. After a particularly deep thrust, her cock brings you over the edge as you freeze in place for a brief moment. She continues fucking you hard even as you start cumming while groaning out loudly in pleasure, shooting an absolutely massive load of that white, gooey liquid onto the floor.

For now, your Mistress doesn't seem to care. She keeps on pounding you as you ride out your incredibly strong orgasm, losing all track of time. After a while Mathilda reaches orgasm too. You can feel her thick cock swell within you for a brief moment as she fucks you just furiously for a short while, the intensity of it making you yelp.

After a while she leans over once more, panting heavily as her huge tits press up against your back again. "You failed to obey me, ****," she says, though her tone of voice is still rather playful, "And failure to obey must be punished." She rests for a while though, enjoying her own orgasm as her cock still throbs inside you.

"I'm sorry, Mistress," you manage to say quietly, though decide to leave it at that. Then you suddenly moan again as Mistress Mathilda pulls out and walks over so that you can see her. She pulls off the condom she was wearing, filled with an almost inhuman amount of cum, before walking over to a door and disappearing for a couple of minutes. She comes back without the condom, her cock finally going flaccid.

"You naughty ****," she says as she grabs a few things from a chest in the dungeon. When she comes back to you, you notice a black latex hood as well as a large ring gag in her hands. Inhaling sharply, you open your mouth for the gag, opening it as wide as you can so it fits. Your jaw will be really aching if she makes you wear it for more than fifteen minutes or so. But it's not like you can or want to stop her. After the gag has been secured, she slips the hood over your head too, robbing you of your ability to see. Sound is slightly muffled but you can still hear.

Then your Mistress walks over and releases the straps holding your legs to the table's before unlocking the padlock, allowing you to stand up a bit unsteadily. You can feel her attaching a leash to your collar. She doesn't say anything but eventually you hear the sound of her heels clicking against the floor and then a tug on the leash, forcing you to follow unless you want to fall over.
