I love being on my knees for you.
Some days you make me wait. You smirk as my mouth falls open in eager anticipation, almost of its own accord. You want to watch me struggle to do as I'm told. You want to see how hard it is for me to keep my eyes fixed on yours, to not let them drop to your cock as you slowly stroke your hardening length right in front of my face. You want me to show you how patient I can be, you want me to earn my reward. And you want to hear me beg, whining as I tell you how much I need your thick cock filling my mouth, that I'm desperate for your cum, and how I promise that I won't spill a drop.
And only then do you push the swollen tip between my lips, telling me what a greedy slut I am as I moan around you, savouring that first taste. You tease me for a while, letting me lick and suck your sensitive head, enjoying my frustrated whimpers, but giving me no more until saliva leaks from my hungry lips and I beg you again to use my mouth. You take your time, your hips moving slowly while my tongue cradles your shaft and my lips glide along it as it slides back and forth, throbbing and leaking precum that quickly mixes with the drool that's now dribbling down my chin.
Your breath quickens and the guiding hand on my head grasps at my hair. Your hips buck, and with a panted curse you finally flood my needy mouth with your release.
