once more and blew along her gleaming cunt to cool her back down.
    "Fuck you, Coop." She laughed breathlessly. "Let your baby come."
    I sat back in my chair after a long, deep lick all the way up her labia, and settled in to observe the pursing of her lips as my fingers plunged into and out of her pink hole. I withdrew my fingers for a moment, spitting more saliva across them, and then returned three fingers to her pussy. Forming the fingers into a generally conical shape, I managed finally to force four fingers inside her. I could detect a faint cupric tang and drove myself wild with desire as the sensations ebbed and built inside her.
    I had to taste her again.
    I withdrew my fingers with an audible pop and attacked her pussy lips again. I licked and sucked and bit and, finally, simply ground my face as she came violently against me. Her body bucked and writhed under me. Her hands reached out quickly to push me away from her sensitive clit, but I held her tightly as I ground and mashed at her sensitive nubbin. With a twist of my wrist, I pushed three fingers into her soaking tunnel and thrust them in and out as hard and as fast as I could. Her orgasm continued. I could feel her muscles tightening and releasing around my fingers as the sensations raged over her.
    After several long minutes, the muscles in her body finally relaxed. She lay back quietly on the desk. Her chest heaved under her breathing. As I lay with my face against her almost completely-shaven pubic mound, I could hear her softly crying.
    "Sonia?" I asked. "Are you okay?"
    "I'm sorry, Coop. Yes."
    I licked her delicately, all the way up her cunt, taking care to avoid her now especially sensitive clit. The taste was exquisite. Feeling her body respond favorably, I slowly slipped two fingers inside her and gently massaged her hardened cervix.
    "Oh my God, yes," she moaned. "I'm totally okay. That was the most beautiful thing I've felt in ages. I am so okay, Cooper. Just ignore me, I'm being a girl."
    She lay on my desk for another few minutes, catching her breath, and slowly twisting her lower body against my exploring fingers. Her scent, hanging heavy in the air, drove me into deeper depths of arousal.
    "You need to come, too," she said after a while. "Let me suck your cock, baby. You can come in my mouth."
    "Not here, Sonia. Can you come back to my place?"
    "Of course," she agreed without hesitation. Sitting up on the desk, she took my face in her hands. She kissed me deeply, probing my mouth with her tongue. Her hands explored my body as we kissed, rubbing my chest and the back of my neck, working the muscles of my back. Finally, for the first time, she kneaded and massaged my cock through my pants.
    "It's so hard."
    "Hard for you, angel," I breathed, as I pulled my mouth from hers. "I hope I don't disappoint you."
    "It's perfect," she declared, squeezing my member even harder. "You're going to feel so good inside me."

    I licked Sonia's beautiful cunt for another few minutes before we slipped her jumper back over her sopping wet body, locked my office, and left. In the elevator we kissed and embraced and dry-fucked through our clothes. Unusually aggressive, she seemed determined to get my cock into her mouth. It became sort of a game to see how far we could go without her actually doing it. It was late now, of course, and most of the building was deserted. There really wasn't a reason why she couldn't go down on me. But I didn't want that here. Not this first time, and not in my building.
    She sated herself eventually by pumping my cock with both her hands as she suckled on two of my fingers. I probably could have come like that, but we reached the first floor and the elevators slid open to reveal the darkened and empty quad and my car parked not far away.
    "Where do you live?" she asked, as we walked quickly, hand in hand, to my car.
    "Just off campus. I have a house."
    Suddenly she became quiet, and I could feel a deep uneasiness descend upon her. A cold
