When I was 26 and doing my Master's Degree, I got a job working at an ESOL school. We would teach people from all over the world. Iran, China, Ethiopia, Russia - you name a country we had a student. They were good students and I liked working there. Every student was diligent, did their best and had life experiences that were genuinely interesting.

There was a colleague of mine who I'll call Carmen. Carmen was much older than me. I never got her age, but she must have been late 40s at least. She had aged well, but you can always tell age from the loose, slightly wrinkly flesh under the triceps. That aside she had toned legs, blue eyes, a pretty face with sharp features - and a shapely ass - always hugged by a tight pencil skirt. Carmen had blonde hair with a few silver gray flecks. She only wore heels, closed toe. She had her first child at 17, that's how innately breedable this woman was. And she was a strict disciplinarian; in class and out. We had a kitchen and classes would rotate on turns to clean it. She would come down like an old fuckable banshee on any teacher who's class made it anything short of spotless - which on occasion was my class.

One night we went had drinks in the staff room and somehow I ended up alone with Carmen in a classroom with all the lights turned off, it is honestly hazy how we even got there. I told her to get on her knees. She did. I told her to open her mouth. She opened wide. I spat in it. She swallowed with a gulp. "You're not going to complain if my class doesn't clean the kitchen to your standards anymore, are you?" She shook her head eagerly looking up at me, a sly smile on the corner of her mouth. I left the classroom leaving her on her knees.

As I got outside, I could hardly believe it myself. I have my moments but I'm not a smooth fucker who is in control of every situation - most people aren't. I had absolutely no idea where that came from. But I knew that I liked it and just as I learned to control a class I was going to take this old show pony for a spin. Being a teacher is fulfilling but stressful. It was time to take a perk.

So began one of the best affairs of my life. Every Friday, myself, Carmen and another 60 year old teacher called Clementine would polish off a bottle of wine in Carmen's class. One night, after Clementine left, I marched Carmen over to her white board using a fistful of her hair - watching her struggle to walk properly in heels. I pushed her face into her board, unbuttoned her pencil skirt and pulled it above her waist. I took her whiteboard marker and wrote my name on her left ass cheek.

"You're my slut now Carmen." I felt her try to nod even though her face was being pushed into the whiteboard. "I'm your slut," she whispered in broken tones. "The marker may wash off, the marker you use to teach your students, but my name is always on your ass."

"It is. I'll know it's there."

And that was all I needed. I gave her ass a hard slap right where my name was then pulled her underwear down around her ankles. I thought about her students who all respected her, what would they think if they saw her like this? The thought made my dick like marble. I speared her old cunt. I didn't waste anytime warming her up and slammed into her, never letting go of her blonde hair with flecks of silver. Carmen screamed and oozed on the cock of a man almost half her age. I smiled sardonically as I railled her. "You know what sluts need? A mantra!," I said over her wails. I hoped everyone had gone home and fear spread as I realized I didn't know for sure.

"Shhhhhhhhhhhhhhhh," I covered her mouth with my hand and slowed down. Her eyes went wide.

"Repeat this for me, okay. Can you repeat what I tell you?" She nodded. "Good girl. your new mantra is 'Obedient sluts cum violently'." I moved my hand away from her mouth.

"Say it."

"Obedient sluts cum... violently." I started pounding her hearder. "Again!." "Obedient sluts cume violently!" I slapped her ass hard leaving a big red handmark over my name. "Obedient sluts cum violently!" she almost yelled, her legs began to shake as her pussy started to clench my dick. The toes of her heels turned inwards as she bent at the knees. My dick flooded her with cum. She's been through menopause, right? I emptied a full load that had built up for at least a week. I helped her stand up properly as she craddled her pussy that dripped seed. Carmen smiled and got down on her knees holding my cum in her and started lapping and cleaning both of us off my cock.

"There. I'll make sure this is as clean as I like the kitchen," her narrow features turned into a crooked grin. Teachers are underpaid, filthy intellectuals. Society doesn't appreciate us enough but thank god we have little sluts like Carmen - it does make up for having to buy the odd piece of stationary. Best affair of my life and one installment in the saga.
