Glucose Challenge

It was the same as it always is: I opened the door, we kissed - his familiar sexy lips - his hands straying down inside the top of my underwear, his fingertips brushing against the ends of my pubic hair, that touch that always sends a frisson of excitement running through my body - but it never lasts long enough - he started finger-fucking me, then he undid his jeans so I could suck him and make him hard enough to fuck me, but he already was, he bent me over and ripped off my underwear. "God, you're so wet," he said as he thrust his cock into my pussy, fucking me like that for a while before pushing me back onto the sofa and mounting me, kissing me while he plunged his cock into me. I was distracted, every time I heard footsteps on the stairs outside I thought it might be Magic coming back to check on me, after the incident that morning, but somehow the fear - the thought that this might be the last time! - excited me further, only not so the Professor - perhaps my relatively subdued nature unsettled him, for he stopped and said, "I think you need to suck me some more," sitting back on the sofa while I got on my hands and knees and sucked, and his cock was just right for sucking, hard enough to turn me on, yet not too hard for me to feel it growing harder in my mouth as my lips closed around the base of it and I ran my tongue up and down the shaft and over the swollen head.

Then he got up to go to the bathroom, and I just sat there on the sofa for a while thinking about things, and then I followed him into the bedroom, where he found me waiting for him on the bed when he emerged. "That's it, get on all fours," he said, dragging me down to the edge of the bed as I wriggled into position, and then holding the back of my neck with his hand and fucking me 'til I came. Exhausted by the strength of my orgasm I collapsed onto my stomach, but he hadn't had enough of me yet, grabbing my ass and pulling it up towards him so he could fuck me more - harder - hitting my swollen, post-orgasmic G-spot with every thrust, 'til all my nerves seemed to ring with the intensity of it, and I clutched the pillows with both hands and buried my face into them to keep from screaming as I came so violently I could hardly bear it.

And then when he turned me around to fuck me more I was limp and unresisting, my pussy slack and wet against his cock as he thrust into me faster and faster, finally pulling back and grabbing my head to bring my mouth to his cock to receive his come. I did as he had instructed me the day before, sucking each long spurt gently, and then as they started to slow, sucking harder to get every last drop of his come into my mouth before I swallowed.

And then he showered and left. I don't think I spoke a single word the entire time.
