It was my senior year at St. Matthew’s Catholic High School, which had transitioned to a coeducational format the previous year. As luck would have it, I found myself in Sister Catherine’s fourth-year German class. Every boy, along with a few girls, desired to be in that class because she was undeniably attractive. Her sensuous curves were evident even beneath the habit she wore. I swear, every boy, myself included, walked out of her classroom feeling exhilarated. It was clear that the girls were also affected, as evidenced by the way their white uniform shirts clung to their bodies, accentuating their figures.

After school, I took the shortcut to the chapel, which meant walking past her classroom. As I approached the closed door, I slowed my pace upon hearing what I assumed was someone in distress. When I reached the door, I paused in the middle of the hallway and looked toward it. To my surprise, the sound I heard was Sister moaning in pleasure.

The black veil and coif were on her desk, I was surprised to see that she had long, perfectly straight dark brown hair. The long black tunic and pleated skirt were hiked up to her waist, I presumed as my viewpoint, didn’t allow me to see much. What I could surmise was that she was masturbating and that's when I heard her say loudly, “Zac, I can’t take it anymore, seeing you walk out of class with that huge bulge in your pants every day. Fuck me, please.”

“Oh God, I’m cuummiinngg!”

Just as I began to move, Sister Catherine glanced over her shoulder, winked, and ran her tongue over her lips coated in black lipstick. Uncertain of what to do, I sprinted down the hall toward the exit door and made my way to the chapel. 

One of the responsibilities of an altar server is to ensure that the chapel is prepared for the next Mass. This Friday, it was my turn, and the first thing I did was check that there were enough missals in each pew's bookrack. I could still feel the embarrassment of being caught—was it real, or was it just my imagination? 

All sorts of thoughts raced through my mind as I went about my duties. I was finishing up in the back room, ensuring that the priest's vestments and the altar servers' vestments were in order. Once I had completed my tasks and checked everything, I noticed that the sun had begun to set. After closing the door through which I had entered, I made sure it was locked before leaving.

That night was restless. Lying in bed, I imagined Sister Catherine without clothes, and the familiar sensation between my legs prompted my hand to wrap around my growing erection.

I engaged in masturbation, envisioning us in various sexual positions. In under five minutes, I ejaculated four times onto my chest and stomach. Afterward, I took a quick shower. Once I returned to bed, it wasn’t long before I fell asleep.

The weekend was like any other, filled with yard work and gathering with friends for a game of football. On Sunday, my family attended Mass, and, of course, Sister Catherine was there. After Mass, she approached me and said, “We need to talk, Zac. Meet me in the chapel on Monday after school.” My parents joined us, and Sister informed them about how well I was performing in her class. 

While they talked, I went outside to wait for my parents, and once again, sinful thoughts invaded my mind. I was certain that I would go to hell for that. However, little did I know what Monday would bring.

The next day, my classes seemed to fly by. Before I realized it, I was sitting in my last class of the day, German 4, with Sister Catherine. Not only did she look good, but she was also incredibly attractive! I knew I was destined for trouble; my only hope seemed to be going to confession. 

“Zac, please answer the question.”

“Uh, what was the question?”

Before she could respond, the dismissal bell rang. I was about to leave when she stopped me at the door. 

“You seemed preoccupied today, Zac. I think I can help you. Meet me in the chapel at four o'clock. Don't forget to lock the door when you arrive.”

“Okay, Sister.”

I left, my mind racing with impure thoughts. Fuck, I’m definitely going to hell.

While passing the time in the library, I began my homework, frequently glancing at the clock, which seemed to be moving at a snail's pace. Concentrating was difficult, and I faced another challenge: an uncomfortable erection. It was now five minutes to four. I discreetly adjusted myself and stood up to leave, hoping no one would notice.

Upon entering the chapel through the side door, I locked it behind me. As I stepped into the main area, I froze at the sight of Sister Catherine. She was on her knees, her long black tunic open, revealing her bare backside. She glanced over her shoulder, her ocean-blue eyes fixed on the obvious bulge in my pants. I couldn't help but admire her beauty, my gaze lingering on her firm, heart-shaped derrière.

“Did anyone see or follow you, Zac?”

“N-no, Sister. What did you want to talk about?” I said in a very nervous voice.

“I was fully aware that you were able to hear what I said as you watched me masturbating in my classroom last Friday.”

“I apologize, Sister. I didn’t mean to. You are so beautiful that I couldn’t help myself.”

“That’s so sweet of you to say! When you got home, did you indulge in thoughts of us engaging in all sorts of naughty activities?”

“Yes,” I said, feeling embarrassed.

“Can you keep what happens here a secret?”

“Yes Sister, I promise.”

“Then come stand in front of me, Zac.”

I moved into position, and her hands immediately unbuckled the belt. Her nimble fingers pulled down the zipper, and in one swift motion, she lowered my pants and boxers.

My cock sprang forth, and she marveled at the sight. “What a magnificent cock you have.”

She wrapped her lips coated in black around the large circumcised cock head.

Her tongue began to swirl around and I nearly lost control.

Sister Catherine licked and sucked her way down the veiny shaft, her head bobbing up and down.

I couldn’t believe tha my first blow job would be given by a nun.

“Oh God, I’m close Sister.”

Hearing that, she wrapped her hand around the shaft. The sensations of her sucking and hand stroking the shaft were too much.

“Sister, I’m cumming!” I moaned as my body convulsed.

She released my member from her warm, wet mouth and looked up at me.

Sister opened her mouth, and it was full of cum.

She swallowed, producing a loud gulping sound.

“Mmm, that was delicious. I hope there's more because I want you to make love to me.

Like a flash of light, I disrobed and moved behind her as she rose to her knees and placed her hands on the floor.

I gently removed her veil as my cock nestled in the valley between those perfect butt cheeks. 

Dropping the veil to the side, I wrapped my hand around my cock and began sliding it between the swollen lips guarding her flower.

Lift your hips now, Sister!” I commanded loudly.

“Yes Sir!”

Thank god she was receptive to that. I decided to explore how far I could push the boundaries of being a bit domineering.

The tip of my tongue brushed against her swollen lips, and I heard a gasp as her body trembled.

“Please, Zac, pleasure me with your tongue!” she pleaded, grinding against my mouth.

I dove in eagerly, like a thirsty puppy. I licked her slit, sucked on the exposed clit, and caressed the puffy labia. Sister was bucking wildly and moaning with pleasure.

“Lift up your hips now, Sister!” I commanded loudly.

“Yes Sir!” 

Thank god she was receptive to that. I decided to explore how far I could push the boundaries of being a bit domineering.

The tip of my tongue touched between her swollen lips, and I heard a gasp as her body trembled.

“Please Zac, pleasure me with your tongue!” She pleaded, grinding against my mouth.

I dove in eagerly, like a thirsty puppy. I licked her slit, sucked on the exposed clit, and caressed the puffy labia. Sister was bucking wildly and moaning with pleasure.

My tongue explored her cunt, and the delicious juices flowed into my mouth.

She was on the verge of an impending orgasm.

I rose up, and with one thrust, I was fully engaged with her. She rocked back and forth along my throbbing shaft. I grasped a handful of her hair and pulled firmly.

“God yes, fuck me hard and fast. I want you to fill me up!”

There was no holding back; we made love like two wild animals. With one final thrust, she was filled with cum.

Thank goodness we were alone behind a locked door. Our moans of ecstasy echoed off the walls of the chapel.

Recovering from our orgasms, my Sister suggested that we say ten Hail Marys and ten Our Fathers. We dressed and knelt in one of the pews.

Finished with our prayers, Sister said, “I hope you keep your word about this being our secret. If you do, we could do this again sometime, Zac.”

“Yes Sister Catherine, I can keep a secret, and I look forward to the next time.”
