As I went to sleep last night, with my mouth using your cock as a pacifier, I heard you softly say, "I wonder what it's like to be ass fucked like I do you, " and I decide to make your inquiry come true.
I wait until you are solidly asleep and very gently and slowly ease your arms up to the leather straps you use on my wrists and fasten yours in. Of course, you are face down and I've arranged the pillows so you'll be comfortable that way. Then making sure you're still asleep I fasten your ankles into the larger ankle harnesses at the bottom of the bed, spreading your legs wide but keeping your ankles secure. There's enough slack for you to move some, but not get entirely loose.
Beside us I lay out an assortment of toys, ass plugs, vibrator, dildos, lube, and a few things you've never seen. I may not use them all but they're there for choice.
I know you'll probably punish me terribly for this but I feel deeply that you ought to be exposed to what slavery is to me. For my needs to be fulfilled in this way is pure bliss. I want you to experience an earth shattering cumming such as I have when you get fucked the way I so love.
Now that I have you tied down nicely, I place myself between your legs and contemplate your ass, your beautiful ass. I gently, tenderly kiss each cheek and kiss my way slowly down to your brown star. I gently lick it, cleaning it with my tongue and then start tonguing it seriously, pushing inward on each lick until I can feel my tongue touch your inner ring. Oh that sweet asshole of yours, so delectable. I start feeding saliva to it, getting it wetter and wetter, continuing to probe it deeply. When I've reached the deepest my tongue will go, I then lick my finger and gently ease it in, keeping my mouth there and adding saliva as it enters.
I then gently start fucking your asshole with my finger and pushing it farther each stroke starting very slowly. When your asshole is taking my entire finger, I wet and add another. Now you are impaled on two fingers and I gently move them around, sliding first toward this side and then that to loosen you up nicely.
Suddenly, I hear your voice. "What are you doing?"
"I'm fulfilling your request, Master, " I reply. "You've been very forward in your taking liberty to do this. "
