Lab Test Anal Sex : Ass-Fucked Daughters 4

Daddy got me a job as an assistant in his lab when I was nineteen.  I mostly just help out and I think Daddy enjoys the company in his big lonely laboratory, and he especially enjoys the little pranks I start to pull on him.

He gets his sinful revenge, pulling down my pants when I have both hands occupied in the glovebox doing an experiment.  I can’t get them out quick enough to stop him from spanking me playfully, and when he does I get very excited indeed.  I want more … much more.  Give it me, Daddy!

“Anything,” I breezed, in sultry tones.  “Anything your heart—or cock—desires.”

I made no secret about looking straight to the crotch of his pants.  His lab-coat was open down the middle and beneath the buckle of his belt sat a huge bulge that appeared to be growing.

“Anything, huh?” he smirked, adjusting his big cock in his pants.

I hummed in excitement as my eyes locked on his crotch.  I tried to make an outline of him, imagining exactly where his cock lay inside his boxer-shorts.

“That looks so big.”

“You can hardly see it.”

“You’re right, Daddy, I can’t.  I need to see more.  I need you to show me more.”

Daddy jostled his cock some more, bouncing it on his fingers and sliding it up and down against the inside of his pants.  Slowly he unclasped his belt and the sound of the clinking metal made my brain turn upside down with lust.  I closed my eyes and listened to the zipper of his pants being pulled down.

“That’s it,” I encouraged.  “Show me.”

He pulled his pants open wide and then ventured inside.  I held my breath as he pulled the appendage up over the waist and then suddenly I was staring right to the forbidden, hard length of my own Daddy.

“That’s big,” I swooned, watching him wrestle his hand around it.

He tugged steadily behind me and I moved my legs together against each other, impatient to feel him against me.  I could feel my pussy becoming damp, but I didn’t just want him in there.

“Are you gonna show me what you do with that?” I asked.

Daddy began to jerk his hand along himself, pinching his way to the tip and manipulating his stiff flesh, like he’d done countless times before.  This time was different though.  This time he was doing it under the watchful eye of his horny nineteen-year-old daughter and I wasn’t gonna let him continue to do it on his own for much longer.

“Why don’t you take down my panties and show me what you do with that thing?” I posed.

Daddy narrowed his eyes and looked down on his big cock, jerking slowly along it as it continued to grow.  It lay across his palm now, stiffer than ever, brought to life by his big, blue veins that stretched up him and to the taut, soft-pink crown.

Daddy stepped out of his shoes and let his pants drop with his boxer-shorts.  He stepped out of them wearing only his lab-coat and shirt.  His huge cock jutted out from between the open fabric, swaying as he walked over to me.

“Mmm, that’s it,” I moaned.  “I want to feel you.”
