Master wishes to go into the cave

Of course he wants to go inside. And you are bound, gagged, and naked. Not exactly spoiled for options. Your master pulls you toward the cave entrance and you hope he isn’t going to take you in there. Luckily (or unluckily honestly) your master finds a root sticking up from the ground and pulls you down to your knees, forcing your head down to the ground as he loops the leash to the root. Your ass is stuck in the air exposing your stuffed anus and (very wet again) cum filled pussy.

Then he reaches into YOUR pack and pulls at the largest mushroom you had picked before, “I’m setting this on your back. If you move it at all, then when I get back not only is this going in your ass, but I’m going to Fuck your ass as well. So dwell on that until I return,” as he makes his threat you swear you see something moving in the woods nearby. You try to respond but the gag stuffed down your throat makes it unintelligible and ‘master’ slaps your ass again as he heads into the cave. Great. Awesome.
