Dear Daddy,
I am writing you this letter with the intention of frankly expressing my desires. I often feel very shy in your presence, so I am thankful for an assignment that allows me to be a bit bolder than I might otherwise feel. I have given a lot of thought to what I hope might happen if given the opportunity to be intimate with you again and, while it feels incredibly vulnerable to be sharing this with you in such an overt manner, I want to show you that I can be a very good girl who follows your instructions.
If you saw fit to do so, Daddy, I would very much like to invite you into my bedroom. I would quietly await your order to disrobe and then I would slowly begin by removing my shirt. I would try very hard to maintain eye contact with you as I followed your instructions, but I am certain I would feel myself flush and would shyly look away as I continued. Then, I would unbuckle my pants and slowly lower them to the floor, placing them in your assigned location. When I removed my socks, you would see that my toes are painted the shade of the bruises I hope you will leave on my body.
When I am sufficiently bare, I would love for you to tell me the exact spot you want me to be on the side of my bed, and I would quickly position myself there so you would see how compliant I can be for you, Daddy. I need you to know how badly I want to feel your leather cuffs on my wrists again. Just thinking and writing about it is making me breathless and hard! Once you contained my body with your restraints, I would love the reassurance of your lips on mine before you shoved me onto my back, harshly whispering, "Slut!"
I would feel so desperate at that point to feel your hips pressed against mine, so fidgety and thirsty to have your cock inside my cunt. I would sneak a peek of you confidently sliding lube down your shaft, giggling to myself about how little, if any, I needed in order for you to enter me. "Please, Daddy," I'd say, writhing beneath your glance.
