He finally gets the courage to go into your puckered anus. he walks up to your ass and you open your hole with your butt muscles. He sticks a leg in and starts to set his other leg in when you clench letting him feel the moisture of your anal walls around him.
He then takes his other leg and puts it in. You then know you have him in your grasp. You start to rapidly clench your anus sliding him in and out but mostly in, immediately he is in awe at your sheer strength, that is until the opening is closed around him.
"Alright, little human, now I want to enjoy this, so squirm around in there while my ass starts to eat you." the human squirms alright, but not because you said so, but because you said you were still going to eat him.
"I thought you were going to let me live."
"Let, you live? See, that's not how things work around here, you could've worshipped my cock or my pecs. But once my ass gets involved things aren't always pretty." you scold him.
"But I don't want to be shit, please don't eat me m-m-master." those words give you a slight joy, but there were more important matters at hand. You kept clenching until he reached your stomach and he kept pleading to.
"Well, looks like you're becoming my shit tonight. goodnight, please let the acids bite" You then begin to doze off but then the human pleas again.
"Look, okay you're going to kill me, but can you please be a little nicer about it."
"okay, fine, I'll be a little nicer to you. But you will be a turd tommorow. So, besides getting out, is there anything else you would like to ask?" you tell him.
He asks you, "Can you um talk to me for a few minutes, I was just scared of you."
"Well, okay, but you cannot just let fear guide you, especially when it just leaves you in, well you know, my bowels. So I've an hour before I have to get to bed so I'll comfort you I guess until then. What do you want to talk about"
