I have been teaching at River High School for five years. I have a special place to take breaks on my own -- on the roof of the gym. The stairway leading to the flat roof is tucked away in back of the gym, a place no-one else seems to go. It's peaceful on the roof, away from the staff and students. Sometimes I'll eat my lunch up there, looking out over the woods behind the gym.
When I began teaching, I persuaded Mrs. Williamson, the Principal, to install a telescope on the gym roof for students to study astronomy. We had a school astronomy club for two years, but that all ended with Covid and after we returned, the Astronomy Club seemed to die out. The telescope was still there, a really nice one, and I could watch deer and other wildlife in the woods while taking a break.
On the day this all began, I was looking through the telescope into a clearing in the woods when I saw two senior-year students. The male was a stocky, blond haired boy named Jeff Kurtz. He was leading a girl by the hand. As I peered closer, I saw it was Diane Preen, a dark-haired girl with a sexy, curvy body. As they entered the clearing, they stopped and looked around. Then, apparently satisfied that they were alone, they began kissing passionately.
After a few minutes, Diane broke away. She took a beach towel from her backpack and laid it on the ground. Then she pulled her tight sweater up and stripped it off. She stood for a minute in her bra and skirt, letting Jeff feast his eyes on her. Then she unhooked the bra and dropped it, revealing a nice pair of firm breasts, with large, puffy nipples. Next, she unzipped her skirt, slid her panties down her legs and kicked them aside. She was shaved and through the lens of the telescope I could see her vulva was swollen and wet.
She kneeled, naked, on the towel in front of Jeff and pulled down his athletic shorts and underwear. Out popped the biggest cock I have ever seen in my life. It was only half erect, but it was already standing out 12 or even 14 inches from Jeff's shaved crotch; huge, thick and dripping pre-cum. Diane looked up at Jeff and smiled. She reached into her backpack, pulled out a bottle of oil and lubed Jeff up. His cock stood massively upright under her touch and she began to masturbate him.
When Jeff was fully erect, Diane made room for him on the towel. Jeff lay on his back and Diane positioned herself on top of him him with her sexy butt on his stomach. She then spread her legs and pulled Jeff's cock between her thighs. From a distance, it looked as though she had a giant cock. Diane began sensually teasing and stroking "her" cock. I zoomed in with the telescope and saw his thick shaft rubbing her vulva and clit as she jacked off.
I was in an erotic trance. My nipples were engorged and I was soaking wet. Sometimes I get aroused in class imagining the young men around me eyeing my breasts and my ass as I walk between the desks. I wonder if they are struggling to control spontaneous erections. I often fantasize having sex with eighteen year old boys who stay hard all night and have never fucked a 30-something woman. But in spite of my fantasy life, I had never witnessed this kind of young lust in the flesh.
I couldn't hear what Diane was saying but she was mouthing words as she pumped Jeff with both hands. She must have been telling him her fantasies and driving him over the edge, because suddenly his cock twitched and he ejaculated all over Diane's belly. As the warm jets soaked her, Diane writhed around, rubbing her vulva and clit on his pumping cock. Diane's body was coated in juice and finally she let go of his cock and let it lay between her thighs, still semi-hard.
After a while they both stood up and Diane looked at her cum soaked body. She spooned some juice off her nipples and licked her fingers, while Jeff dried himself on the towel. Then Diane toweled her sticky body and dressed herself. The pair walked off into the woods, and I was left alone on the roof. I felt an intense urge to get out of there quickly, like I had witnessed something forbidden.
I drove home in a daze, cooked myself a simple dinner and drank a glass of wine. My mind was full of images. There was something intensely perverse and erotic about the way Diane had posed with Jeff's cock, like a hermaphrodite with a massive erection. Then there was the flood of sperm. I had never seen a man cum in such volume.
I imagined Diane laying in bed at home, naked, smelling of cum, her body soft and sticky from his residue. I was very aroused. I stripped off my clothes and walked around my empty apartment naked. The cool air made my nipples hard and I caressed my big breasts and touched my clit. I stroked my swollen vulva against the back of a kitchen chair. Then I rubbed my clit against a wooden door knob until I came, sobbing with the release. But even after orgasm, I wasn't satisfied. I needed more orgasms.
Sometimes I can go without sex or even masturbating for weeks or months. But when I get horny, I go on binges. I will find a guy and have non-stop sex with him for a whole weekend. If there's no-one to hook up with, I masturbate continuously. Sometimes I watch porn until late into the night. I binge on that too. I thought about going to a bar and picking up a young man. He had to be young and ready to go all night long. It was a week night and way too late for that.
Finally I lay in bed and masturbated for hours. I fantasized about Diane with a massive cock, mounting me and pumping my juicy slit until she came deep inside me, her cum juice overflowing my pussy and dripping down my thighs. I came several times to this fantasy, moaning and crying out loud with lust and frustration. Then I imagined seducing Jeff in a classroom after school -- stripping for him and pushing my scented pussy into his face as I gripped his massive cock. I wanted his mouth on my nipples, his strong arms forcing me down on my desk, spreading my thighs with his rough hands, ramming into me, rigid with desire, fucking me until I was red and stinging.
