Invite all three brothers into your bed
From Create Your Own Story
You can't help but giggle at their brazen behavior; they surely wouldn't do this with anyone else. You also take a bit of pity on them. Despite the fact that they're not the ones about to take the throne, nor has there ever been a conversation of them ever doing so, with the announcement of you taking it, they've all had to table their own indulgences and vices, so as to avoid overly critical eyes. This vice, however, has never been found out about, despite being intimate with them for years. Sucking them off might take the edge off for a little while, but they won't last long. Better for everyone if you go all the way. You sit up on all fours with your hands and legs spread, your pussy and asshole exposed, both familiar sights to the triplets.
"Awww, you poor boys. You must be struggling so hard keeping it in your pants for this long." You look over your shoulder at them, slowly moving your ass side to side, to tease and taunt them. "I bet you're all so full of cum you're about to explode. Come here boys, fill your big sister up with those big hard cocks." They practically leap into bed with you, once they know you're ready to go even further than they had asked for.
You start by sucking and stroking their dicks like they had wanted, and fondle their balls with your hands for a little extra encouragement. With all of their manhoods properly wet and lubed up with your saliva, they eagerly take all of your holes. It's been too long for you too, apparently, as you reach a climax in no time flat.
With how luxurious and hedonistic your life, and life in the kingdom in general, has been, regular intimacy doesn't always do it for you. You've never been without a suitor, oftentimes several, and up to a point it starts to feel somewhat routine. Nearly all of them want you to themselves exclusively, if only for an evening, so getting a moment like this is rare. A moment where you don't have to worry about what the guy wants, feels, or thinks when they leave is even rarer still, so you just relax for now and let the boys pound you for all they have, which is a lot. They change hands several times so that each of them gets to feel your wet pussy, your tight ass, and your eager throat. You also cum several times, letting each wash over you in a wave of pleasure.
All four of you have been taking Maiden Tea for years so as to prevent any unintended pregnancies so you have no concern where they decide to finish. Michael, Gabriel, and Raphael all cum in their preferred receptacles, leaving each your holes full of hot white spunk.
To avoid detection, the triplets get dressed quickly and quietly, disappearing off into the castle somewhere. You on the other hand, lay in bed for a few more moments, enjoying the sheer ecstasy of what just transpired. Thankfully, the soreness you had earlier has left you.
With that, as you eventually rise out of bed, you have a few moments before preparations for the big day arrives.
Best to get started early, there's a lot to do
