I start to churn your cock with one hand, my mouth working on the tip and the first few inches. Occasionally I plunge down, taking you deep into my mouth, nearly into my throat. It tastes so good, I want more, and I revel in the weight and thickness crowding my mouth, stretching my lips wide. I slide my tongue all along your length, and then lap at the silky stream of cum from the tip. You start to shudder and shake and I know you are going to cum. I open my mouth and throat wide to receive it, to suck and swallow it all down, every tasty drop. You cum so hard and with so much I can barely keep up, some spills out of the corners of my mouth. I let go of your pumping cock to lick at the corners of my mouth, and you spurt onto my breast. I reach up and rub your cum into them, getting them wet and sticky. You reach around and unhook my bra, throw it to the floor, then lean down to lick your cum off my tits. You take a nipple into your mouth and suck, lick and bite, worrying the little knot of flesh between your teeth until I moan and gasp.
My panties are completely wet, the black silkiness of the crotch sticking to me. I rake my fingers through your hair and whisper hotly in your ear "fuck me baby, fuck me now. Please." You pull me up and clear your desk with one sweep your hand, then push me up onto the desk. I spread my thighs for you, writhing in heated anticipation. You undo you pants the rest of the way and let them fall and with one hand push aside the crotch of my panties, pausing briefly to rub my swollen clit. Like some extra sensitive button, I take a sharp intake of breath and shake when you touch me there. It's driving me wild, your thumb roughly rubbing the nub in maddening circles. Then with the other hand you guide your cock, hardened again, deep into my steaming soaking cunt.
You buck and thrust deeply into me, the force of your fucking making my breasts shake and your desk move a bit with every thrust. I pant and mewl like a cat, hold my thighs wider and push against you to try and get more of your cock in deeper. You feel so big inside my tight wet cunt, it feels like you are ripping me apart, and I want more, deeper, harder. "Yes, oh yes. Fuck me, I want to feel you cum inside me baby." I say and you go wild, bucking faster and harder. I can feel your cock hitting me deep inside, bumping, unable to go further. The walls of my cunt start to spasm, and clench, throbbing around your cock. I'm losing my breath, my moans are getting louder, and you try to cover my mouth with your hand so I don't attract unwanted attention from outside the door.
And then I feel you shudder and cum erupting inside me, filling me up. You collapse on top of me, your cock pumping inside me, and I wrap my legs around your waist. And as the last shot of your hot cum fires into me, you inch down and suck on my nipple again. I rub your head and tremble underneath you, completely satisfied.
