Alright, let's get you ready. First off, I want you gagged and bound up. Your mouth should be filled (I hope you remember where you left your dildo-gag, dear) and your hands cuffed behind your back.
Stay on your knees and look at me. Think about what it would be like to be free of that cage. Imagine me running this tongue up and down your body like I've done so many times before, circling slowly round to your nether regions. Imagine me taking you in my mouth, slowly teasing you with a long, luxuriant blowjob until you were about ready to pop, pulling away at the last minute.
Imagine how, after giving you a moment to cool off, I would finally lay you backwards against the bed and position myself on top of you, caressing the tip of your upright cock with the lips of my temple until at last I let it penetrate, slowly sinking down under my own weight onto you...
Think of how beautiful it would be, holding off for me as you always have, letting me know when you're about to blow so that I can slow my thrusting and keep it going for hours and hours... that desire you feel every day, magnified a hundredfold, taking over your mind until finally, finally, I looked deep into your eyes and said "Yes".
