"Untie my belt", your mom says as she looks down at you.
You suddenly feel your nervousness return. Your heart starts thumping again, your breathing gets heavier and you can feel yourself trembling.
"Y..yes mistress", you reply.
You manage to control your hands long enough to unfasten the belt on your mom's bathrobe, and then pull the robe open. You let out an involuntary gasp as you find yourself staring at your mom's fully shaven pussy.
Your mom pushes the robe behind as she puts her hands on her hips.
"Like what you see"? she asks.
"Y..yes mistress", you say softly. "It's beautiful".
"So, you'll really do anything I want, huh"? Your mom asks.
"Yes mistress", you reply. "I'm your slave. The only purpose to my existence is to please you".
"Good", your mom says. "Because I need to pee. So as my slave, I guess you won't mind if I use your mouth for a toilet"?
To your surprise, you find yourself feeling somewhat excited. You know it's going to taste disgusting, but you don't care. This will be your first act of service as your mom's slave.
"Not at all mistress", you say, trying not to sound excited. "It will be my honor to be your toilet". And with that, you tip your head back and open your mouth wide.
Your mom giggles and says, "I think I'm going to enjoy having a willing slave".
She moves herself over your face and then sits. You can feel her warm skin as it presses against your open mouth, as your dick starts to get hard. You then feel the same tingling you felt other, which is strange. After a couple of seconds a warm, foul tasting stream of urine hits your tongue and runs down your throat. Your instinct is to pull away, but you somehow manage to overcome the urge. To your surprise, you don't have to swallow. Now you know what the tingling did. Your mom must have made it so you didn't need to swallow, which makes things a whole lot easier. You're also surprised that you're not gagging. Maybe your mom got rid of that reflex too.
You're not sure how long it takes, 40 seconds to a minute maybe. Eventually though, the stream weakens until only a few drops remain, and then it stops. Then your mom stands up.
"Close your mouth", she commands.
You do as she says, and she then gently wipes herself dry on your face.
"You make a very nice toilet, slave", your mom says with a slight giggle.
"Thank you mistress", you reply.
Your mom then smiles down at you and orders you to lie on your back. As you do so, she stands astride your head and then sinks down to her knees.
