A scene I imagined keeps roaming my mind lately...

Mommy makes me get on my knees in bed, then blindfolds me and ties my hands behind my back, leaving me at her mercy, unable to resist or even see what she wants to do with me. She gets behind me, licking my ears and whispering naughty things, as both her hands slide up and down my body. My mouth, chest, tummy, waist, thighs... I can feel her soft hands everywhere, except for the one place I'm craving to have touched. As my desire ramps up, my breathing becomes a mess, and between my loud moans, I barely manage to utter some desperate begs for mommy to please touch me down there, because I can't hold it anymore. And she does indeed touch me, but not as I wanted. Instead, she very lightly traces one fingertip up and down my shaft, making my urges almost unbearable. She then pokes a little fun at me, but also praises me, saying "you should have been more specific with your begs, darling. Now be a good boy and stay still for mommy, let her enjoy your needy whimpers as much as she wants, and I promise I will milk every last drop of cum out of your pretty cock". That makes me lose my last ounce of self-control and strength, and completely surrender myself to mommy's wishes.
