I slide my dark, innocent eyes up to your face as you slip the thick head of your cock from your pants. I lose my breath, knowing what you want from me is my first blow job. I am scared of the unknown and the path this act will set my feet upon but I part my lips obediently and slide the tip of my tongue over the smooth crown of your erect penis, lapping.

Your moan encourages me to be bolder and I slip my lips all the way over the head. It's soft and dry and smooth, and I imagine that it almost squeaks like taut cling wrap might when rubbed, as I wet it with my tongue and take it deeper into my mouth.

"Good girl," you mutter, and the words thrill me.

I try to respond in words. I want to ask you if it's okay. Is it good, is this how you want it to be, but with my pretty mouth full of cock I just end up making a sucking motion that you enjoy, groaning loudly and grasping at my head as if to stop my escape from your pleasure.

I suck harder, my small hands grasping your balls which bounce gently under your own hand which is slowly wanking your cock as it rests between my lips. Your balls are wrinkled and hairy, reddish in colour and they remind me of your age, so much older than me but age doesn't seem to matter in my head because attraction is so strong between us.

I love your experience and knowledge, you have such a sense of strength and power about you. But I know that makes what we are doing so much dirtier in the eyes of convention and the rebel in me grows more excited to think that I am defying the world to be with you. I wonder what your wife will think when I finally steal you away from the life that you share with her. Will she be surprised about you and the babysitter or did she see me coming? Surely she must have noticed the chemistry between us and the times you slipped away to come home early.

My small hands on your heavy sac seem to excite you more and your hips move you closer, your cock sliding deeper into my mouth. A salty dribble of pre cum slides down the back of my tongue and you groan louder, your breathing hard and fast.

I suck harder, encouraged, hoping this is right, wanting to please, and your fist moves faster over your cock, wanking it into my mouth, fucking my pink, parted lips.

Your free hand slides up my pleated skirt and fumbles your thick fingers into the side of my panties. I squirm, excited, a little shocked that you are touching me there, and I like it so much. I am aching, tingling, pushing my tight, wet little pussy against your curious fingers as I suck. My moans hum a vibration against the head of your cock as you fuck my mouth harder.

I lift my eyes to your face once more, watching the excitement on your face as your cock pounds my lips, watching the bead of sweat trickle from your brow and slide down your weathered cheek.

"Oh yes," you groan, as my hum vibrates against the rim of your cock head.

You seem to like that a lot so I hum louder, rubbing and slapping my tongue against the rim. My greedy little pussy is soaking your fingers as you explore all my forbidden, untouched places, and I am trembling. The more excited I become the harder I suck on your cock, my small fingers kneading and caressing your balls.

You thrust your swollen, excited cock hard into my mouth, grunting like a mindless animal. I gasp for air as your eager, excited cock shoves in and out of my sucking lips.

"Take my load," you shout, and I fear we will be overheard.

I part my lips wider, tilting my head to take you in deep as you cum, spurting your hot, salty load right down my throat and filling my mouth with so much it escapes my lips and dribbles down my chin. Your fingers keep sliding over my tight, excited little clit and I burst with pleasure as I cum too, your cock still rammed deep in my mouth, your spunk swallowed with my little pleasure gasps.

You pull your cock free and stroke the tip of your thumb against my parted lips as I gaze at you with steady devotion. I know that everything has changed now and from here we will travel on, towards new adventures, together.

"Happy birthday, sweet sixteen," you whisper in my ear.
