Cadance's request (WIP)

You've been invited to the Crystal Empire upon Princess Cadance's request
>Funnily enough, the letter was from Luna
>You sit down in a meeting room with her and Shining Armor
>She tells you straight off that Shining is 100% OK with what she's about to tell and ask you
>As an alicorn, she has...needs. And Shining can't take care of them.
>He admits it's more like he WON'T take care of them. It makes him too uncomfortable and he can't bring himself to do what she wants
>She explains that she had Luna send out a few dreams, to see who would respond positively, about sucking and taking marecock
>Now you know why you kept having those wet dreams and having to wash your sheets all the time
>Shining blurts out the request before she does
>"Could you take care of my wife's marecock for me please?"
>You respond that you're not cucking a prince, and it's wrong to have sex with someone else' wife
>"Oh, no, you won't be penetrating me at all. Shining is the only one who gets to do that. We're just asking if maybe you'd like to...take mine...into your body...whenever I need it?"
>For a princess of love she sure gets nervous talking about it
>You hesitate for a moment, thinking about the ramifications of getting in between their marriage, but she thinks you're going to reject her
>She immediately stands up and puts both her hooves on the table and whispers something to Shining
>He shrugs, then reaches a hoof over and stuff it in her backside
>You notice the large pair of balls sitting on the edge of the table, beneath an expanding sheath
>Her breath catches for a moment before getting quite heavy
>You can't look away as a pink marecock the length of your forearm and the width of a can of red bull slowly extends and rises, standing proudly in the air over the table
>You lean forward, trying to hide your own boner
>"See what I have to work with?" he asks
>"Please?" You hear her say, but you couldn't take your eyes off of it, "I could make it worth your while."
>You try to speak, but you're enamored with the throbbing round flare at the end of it that's dripping pre
>A drop separates from the bottom of the flair and lands on the table, which breaks the spell.
"Yes! Yes please!"
