"Don't cum yet! I have plans for that cum!
Now, remember all that beer you're going to chug? Eventually, it's going to have to come out. You know the old joke about beer: it ain't a purchase, it's a rental. Well, when you can't hold it any more, I want you to make me lie down on the bed face up, while you straddle me with your ass facing my mouth, and I'll give you the deepest rimjob yet. Then you'll start pissing on me.
It might take a while, of couse, because I know it's not easy for you guys to piss through your erections. But that's fine. I'll be making out with your asshole for as long as it takes. When you're ready, I want you to savor the feeling of pissing all over my body while my tounge is still in your ass.
I'm counting on you to have a lot of piss built up, because once you've drenched my body, I want you to pause and stand up so that I can kneel down in front of you with my mouth open. Then you'll piss in my face, making sure to drench my hair too, before you start fucking my mouth with your dirty, still-pissing cock."
"Wow. You've really thought this through. You're amazing. I can't believe how many of my kinks you've combined into a single plan."
"I'm not quite done yet. At this point my mouth will be full of the taste of your piss (and a good amount of that piss will be in my belly), which means it will be time to take my buttplug out and shove it in my mouth to get the taste of ass again. If you can, I want you to save the last of your piss so that you can piss into my asshole as you start to fuck it."
"Jesus."
"Now comes the big climax: after as many final rounds as you want of making me go ass-to-mouth, I want you to fill my ass with your cum, where it will mix with your piss. Then I'll walk over to where I've prepared a large, shallow bowl in front of a mirror. I'll squat down over the bowl, with my back to the mirror. You'll stand in front of me, and take your cock in my mouth.
While I'm cleaning your cock with my mouth, you can watch in the mirror as I shit out the mixture of your cum and piss into the bowl.
Then, once your cock is spotlessly clean, you're going to watch as I drink down every last drop of your cum and piss from the bowl. I'll lick it clean, too."
"You truly have thought of everything, babe. But what about you? Are you going to be masturbating this whole time?"
"Absolutely not. Tonight's about you, not me. In fact, you're going to start by handcuffing my hands behind my back. My mouth and my asshole are all I need to use tonight. I know my pussy will be dripping this whole time, but we're both going to ignore that. Remember, just for your birthday, I'm an anal-only gal. I might cum while you fuck my ass or I might not β it doesn't matter at all. Your pleasure is all that matters tonight."
"You are so perfect, babe. I don't deserve you. Just hearing you describe all this has already made this the best birthday of my life. But this is all so far beyond anything we've ever done before. Are you sure you want to do this?"
"Oh, I'm deadly serious, buster. I've never been more sure about anything in my life. Here are the handcuffs. Let's get started."
