Rest first

"Rest break!" she exclaimed with a grin. "I'll be right back with something refreshing. No napping now!" She wagged a finger at him playfully. She then put her lab coat back on and left the room.

I sat down in the chair I'd been using all day and thought about all the wonderful sensations Dr. Jones had given me.

She returned in a couple minutes with a can of Adrenaline Rush. "This should keep you awake for the rest of the day." She walked over to me, sat on my lap and handed me the energy drink. She fit my limp dick into her pussy fold and started flexing her hips, rubbing her nether lips up and down my noodle. It was soon not a noodle, but a shaft. She unbuttoned her coat, but left it on.

I sipped the drink with one hand and fondled her smooth round tit with the other. She kept the lap dance up for the five minutes it took to finish the refreshing soda. I drained the last of the liquid and put the can down on the nearby table with a flourish.

"All done! Let's play hockey!" I said with a laugh.

She stood up and knelt before me; it wasn't until she leaned forward to suck the knob of my cock into her delightful mouth that I noticed she had put her hair up again. My member was again surrounded by her expert mouth, all warm and wet. Her tongue was a marvel on my skin. She kept looking up at me with heated desire in her eyes as she bobbed up and down, taking more of my length into her mouth on each cycle. She shifted her body, and I could see that she was slipping two fingers into her insatiable oozing snatch. I was in ecstasy; watching her frigging her cunt while she was blowing me just about got me off, but all the sex we'd had was going to make that very difficult.

After about five amazing minutes of sucking and licking, I think she realized that I wasn't going anywhere. I had my eyes closed and my head tilted back, just enjoying the moment, when I felt her fingers playing with my asshole. My eyes snapped open and I looked down, squirming a bit, but she took that moment to deepthroat me and started swallowing. The feeling of the back of her throat squeezing my prick head sent me to the moon, and I moaned deeply and arched my back.

Her fingertips slippery with her own juices, she pressed gently against my virgin rosebud until I relaxed enough for one finger to slip in. The stretching of my anus made me shout, "Fuck!" and then she pushed all the way inside me. Her mouth never stopped its work on my cock, but my mind focussed on my asshole. As she slowly thrust her finger in and out, the slight pain of the intrusion subsided into an pretty intense pleasure. Suddenly, she hit something in my ass that just about made my head explode. I had heard of the prostate and that some men found it fantastic when rubbed, but I never realized just how good it would feel. I relaxed a lot after that, and she took that opening to fit another finger into my butt. I screamed at the increase in tension on my sphincter, and my hips jolted up into her mouth, making her gag just a bit. She was still deepthroating me, and, when her fingers started fondling around the lump of my prostate, generating incredibly good nerve impulses, my mind and body gave in, and I could feel my balls pumping what little they must have had.

"God, Dr. Jones, you've got me cumming again! Unh!" I said through gritted teeth. She grabbed a vial out of her coat pocket and pulled off my quivering dick. She shucked it with the hand she had quickly removed from my ass and caught my eruption in the test tube. In her usual expertise, she gathered every drop that I jettisoned.

"Eight! You've tied the record!" she shouted with a big smile that held a hint of her lingering lust in it.
