Sometimes laying in bed, the best thing about having a slave is...when I am too lazy to get up, I piss in her mouth instead. After she processes my energy, she can get up to pee but I don't need to. See, you thought BDSM relationships didn't have perks but you'd be so wrong.
Some reader may think, yeah, but you're the Master! What about for her?!? Well, she's a slutty submissive slut. She's constantly hoping I will piss in her mouth. And it gives her the opportunity to try and blow me at the same time so she gets some more action. Slaves are awesome. I don't know why anyone would choose to live without one.
'Cause pissing in a slave's mouth instead of getting up at night is the most convenient thing ever.
