The professor’s pet

Tim's POV

"Tim, I know you are wondering why I invited you over to my place on a weekend, but I am noticing a steep decline in your grades." Dr.Voss said.

I met her look for a second, and then I shifted my gaze. “Doctor, I know. I've just been distracted; I am so sorry. I want to improve, but I'm just not sure how.”

She set the drinks down and moved closer to me. "That is why you came here tonight," she said in a very low voice. "I have an offer for you, but only if you are interested.”

My heart raced. “Anything. I’ll do anything ma’am.”

"Good." She said with a smile. "Tonight you'll learn all the tricks to getting A's—even when distracted.

My heart drummed in my chest with the hope that it would be fulfilled... my crazy fantasy to be fucked by the same lecturer I jerked off to.

“Now,” she said softly, “stand up.”

I stood there and felt small under her gaze. “Take off your shirt.”

I hesitated for a split second before obeying.

“Good boy. Now your pants.”

I unbuttoned my belt and took off my pants and boxers, watching my cock spring free.

She held my semi-hard cock in her hand, warm and soft. “This is mine now.” She said as she held my hand and led me to her bedroom.

“On your knees.” She ordered as she gave a light slap to my cock.

As I obeyed , my heart raced. She slowly opened her blouse, revealing a black lace bra over her breasts. She unzipped her skirt and let it fall.

“Tim, worship me,” she purred, “lying back on the bed. Start with my feet.”

I bend down and begin to kiss her toes, moving slowly up her calves. She opens her legs, inviting me even closer. Higher.

I kissed her thighs, and she drew me even closer. “Lick.”

I pressed my mouth against her panties, tasting the juices seeping from her. She breathed deep and took off her panties. “Use your tongue on my pussy.”

I obeyed, sucking her erect clit softly. It tasted salty. She pressed her pussy down against me and made me pant.

“ harder , Tim,” she moaned. “Eat my pussy like you mean it.

I thrust my tongue inside,greedily sucking her clit like a vacuum.

After a few minutes, she pushed my head back. “Enough. Lay down.”

I did as I was told. She went to the side drawer, pulled out the handcuffs, and started securing my wrists onto the headboard. “You are mine to use. Mine to fuck as I please.”

Strapping a big, curved, black dildo with veins to her waist , she said, “I'm going to use this on your ass, Tim. Beg me. Beg me to fuck your ass.”

“Please, Doctor Voss. Use it on my ass,” I begged.

“Good boy,” she said, slowly applying lube on my hole,teasing me by slipping one of her fingers into my ass.

She positioned herself between my legs and lifted them high over her shoulders. "Relax else it’s gonna hurt more," she said, prying the dildo against my ass.

“I’m sure Jake must have told you this.” She said, reminding me of my first gay fuck…with a senior called Jake in the school’s library.

“Dr.Voss!” I screamed as she slammed the dildo into my ass, painfully stretching my hole.

“Take it like the good boy you are.” She hissed as she began to thrust in and out, each sending equal waves of pain and pleasure through me.

“Do you like this in your ass? Do you like watching me fuck your asshole? Do I fuck you better than Jake?” she asked.

“Yes! Yes! Mommy! You fuck me better than Jake.” I moaned.

“Not yet.” She said as she sensed my orgasm growing near.

“You do not cum unless I say so.” She said as she gently slapped my cock, left and right, repeatedly.

She uncuffed one of my arms and flipped me onto my stomach. “Ass up.”

I arched my back, using one hand to spread my ass as she lubed me again.

Her hands gripped firm on my hips as she slammed the dildo in once more, pounding into my ass.

“Mommy…it hurts.” I begged, feeling the dildo tear up my ass, painfully stretching it.

“Take it all,” she growled.

I groaned and bit down on the pillow .

“A’s don’t come easy you whore.” She hissed as one of her hands grabbed my cock, tightly squeezing it to ensure I do not cum.

“Please, let me cum,” I begged.

“No,” she said sharply, removing and tossing away the dildo.

“On your back.” She ordered.

I did as she said, seeing as she sat on my cock, each inch disappearing into her wet pussy.

“Slowly,” she began to ride me, her huge tits swaying as she bounced on my cock.

I groaned rolling my eyes back as her wet and warm pussy gripped my cock tightly. Realizing I was getting close, she suddenly stopped, squeezing my cock.

“Hold it,” she said.

I whimpered.

“My turn on your face.” She said as she hovered over my face, her pussy was on my mouth in a 69 position.

“Lick while I stroke you,” she said.

I flicked my tongue over her clit, sucking as she slowly stroked my cock.

She pressed down against my mouth, her ass against my forehead.

She edged me three times, leaving me damn close.

“You remember,” she whispered. “You're my pet now. You cum when I say.”

“Yes mommy.” I said, as I greedily sucked on her clit, gently biting on it.

“Stop…” she screamed, as she stood up and freed my hands. “Fuck me hard, show me how much you want that A.” She said as she laid down in a doggy position, her pussy and ass bared in front of me.

“Yes mommy.” I said as I slapped her pussy lips, causing the fat swollen flesh to jiggle.

I held her hips as I began to thrust into her ass, and she yelled into the pillow.

“Cum in me.” She moaned, moving her ass to meet my dick.

But I had other plans as I pulled out and grabbed a handful of her hair, making her face me and and thrust my cock into her mouth forcefully to the point it made her gag, and there were tears in her eyes.

“Swallow every single drop, taste your slut’s cum,” I said as I came, shooting my hot loads down her throat.

After that intense orgasm, I collapsed to the bed but I immediately tensed up as I felt my asshole stretch, painfully.

""It's time to pay up", she hissed, and shoved the dildo into my ass." A's don't come easy, you dirty slut."
