First, I would kiss you so slowly, and sensually--while caressing you with feather-light touches--until I get you so hot, the kissing becomes explosively passionate! I'd break away from your lips to start kissing your neck, then down your chest, to your stomach, and below...I'd nestle my face beside your cock--pausing there, to lightly glide my closed-lips slowly up your shaft to tease you. I'd kiss my way back down to the base...and further...past your balls, to your taint--the little strip of sensitive skin between your balls and ass--and I would kiss there too. Then, licking my way back up--I stop at your ball sack, gently pressing the skin between my lips, and tickling it with the tip of my tongue.
I'd start sucking on your balls--and with one, or both in my mouth, I'd pull my chin down for a gentle tug. Very slowly I'd inch my mouth up your shaft, open-mouthed, like a fish with a tongue--opening/closing along the way, with my gripping lips cupping your girth, creating tingling with my soft tongue. Moving up, from front to sides, my mouth inching up your cock, as if I'm french kissing it with adoration.
When my mouth reaches the head--I'd circle it with my tongue...open-mouthed, so I can tease you better. The tip of my tongue would dip into the tiny hole, where a drop of your pre-cum is sitting, just waiting to be licked up. Then, I'd surprise you by suddenly taking the entire head in my mouth at once.
The head inside my mouth helps get it wet, and with my gentle sucking, and swirling of my tongue--saliva builds. I push the wetness down your shaft with my engulfing, gripping lips. My mouth then finds a rhythm of moving...up/down, and up/down, repeatedly on your shaft--gliding, and sucking, while coming back to the head again, and again, to swirl it with my tongue on every upward movement.
After sensing you're really getting into it, I make a change--to draw it out, and build intensity.  This time, with my mouth closing over the head again, my hand starts simultaneously stroking your shaft--ever so lightly--but it needs more wetness. On the next up movement, my fingers come over the head, and into my mouth, touching the head as I lick both--getting my fingers wet enough to glide up, and down your shaft easily, while simultaneously sucking the head.
