Like a spark to tinder

It's some time before I hear footsteps outside my office, and a few seconds more before I hear a gentle tap of a knock. "Come in," I call softly, warmly, to my late-night guest. The door is opened and closed quickly; I barely even get to register her silhouette before she closes the door behind her. There's no light in the room, and I can tell the girl is taken by surprise by the fact. "Don't worry about the darkness. I figured this would be best to help you... acclimate, to a new dynamic here. No need to rush yourself, take your time." I hear her slowly step closer, her soft breathing approaching. "It's alright. There's nothing between us that you might trip on. I'm right here." I feel her hand brush my knee, then come to rest there for a moment before it slowly, gently starts to move again. Over my knee, up my leg, my thigh, before once again coming to a stop, resting on my zipper, lightly squeezing and caressing my bulge, before carefully unzipping my pants and kneeling between my legs. I hold my breath as my dick springs out. I feel her lightly grasp my member with one, then both, of her hands. I groan in pleasure as she slowly starts to pump her hands up and down my shaft. "Keep going. God that feels amazing." Emboldened by my words, she starts to pump faster, and faster. I can't help but groan louder as the glorious torment continues until, to my astonishment, I feel her warm, wet tongue softly lick it's way from the base of my shaft to the tip of it's head. I give a surprised shudder of a gasp and feel myself release. One, two, three, more and more shots of cum erupt from me, no doubt coating her in my spunk. I hear her gasp as the first shots hit her, then she grows silent. When I finish I gasp out, "Hanna... holy fuck... that was amazing..." I reach forward to pull her to me, but my hand finds only air. "Hanna?" Suddenly my door opens. The sudden, unexpected light blinds me for a moment and I hear the door close while I'm unable to see her leave.
