All the characters were 18+ years old at the time.
I was a Class 12 Student in Delhi, studying at one of the top schools in the city, and aspiring to the IITs. Sadly, I was one of the breed of nerds, who had little to no luck with members of the opposite sex.
I did have a crush on one of my classmates, a voluptuous girl called Aakanksha. She was a joyful girl with the smile of an angel and a glint in her eyes that wreaked mischief. Her body was the envy of the girls and the lust of the boys, with 34D boobs that stood firm and a curvaceous ass that was the centrefold of many of my jerk-off sessions.
She always looked good in the hideous school uniforms, with her shirt one size too small, and her skirt too short, her tits bursting out of her shirt, and her nipples poking out on the colder days.
She and I shared a Chemistry Lab class together, where she was my Lab partner, and after most Lab classes I was hard from sneaking looks at her tits. On one such day, I bunked the next class and stayed outside, I was nursing a hard-on, and finding a secluded corner, took my cock out and started to fantasise about making her kneel on her knees with her tits out and make her suck my cock, then bend her over as I fucked her her in the ass.
I was leaking precum, when, suddenly, she turned around the corner and came face to face with me. Startled, she looked down to where my hand was, and as I hurriedly tried to cover myself, she looked up at me with shock.I expected a slap and moved away, but she didn't move and, after a moment, seemed to be calming down. I scurried away, before things got worse, and didn't go to class the entire day.
I avoided her over the next few days, but as Chemistry Lab class came again, it was unavoidable. I averted my gaze from hers, while she took every opportunity to interact with me. She was enjoying my embarrassment, and when I looked up at her, I saw her with a faint, naughty smile at her lips. I was mesmerised, and knew we were behind our awkward meeting.
The next few weeks went by in a blur, and I was happier than ever. I had a new friend, and I used every opportunity to talk to her, or be near her. I used to slyly look at her every day, and always walked behind her on the stairs, staring at her ass, wishing to get a glimpse up her skirt. I was always hard, and had learnt to hide it in the waistband of my briefs. I jerked off to her every single night.
As our exams came near, she asked me once if she could come over after school as she had some issues with the curriculum, and one fateful day, she called in the afternoon and came over! It was a fateful day, because I was alone at home, since my father was at work and my mother was leaving for some NGO activity, and both wouldn't be back before 8PM.
She arrived around 4PM, wearing a pink polo t-shirt, white above-knee skirt and loafers. We sat in my room to study Mathematics, with me sitting on my bed while she took over the study table. An hour later, I looked up to see her with her eyes closed and head tilted backwards, her boobs moving up and down in slow rhythmic breathing and her legs slightly open. She shifted a little in the seat to make herself more comfortable, and her skirt hunched up a little to show more of her soft thighs.
After a mind-numbing hour of studying, my cock jumped to attention at this beautiful sight, and before long I was gently rubbing my cock through my jeans. I quickly sneaked a photo of her on the phone, and got up to jerk off in the bathroom to the photo. As I was quietly crossing her, I saw her phone lying on the table, unlocked, and in a moment of stupidity, I picked it up. I opened her Photos App and scrolled down looking at her photos - photos of her family, her dog, and her out with her girlfriends. Then a couple of photos caught my eye - a selfie of Aakanksha in a black lace bra, one of her turned around, showing her ass in a matching black thong. And then a full frontal in the black lingerie set, followed by one in the thong but no bra - her hands covering her assets, but barely. The last photo was the most erotic of all, she was crouched facing away from the camera, on her knees, legs spread apart. From that view her ass cheeks were spread apart, and her black thong was wedged in between, her asshole barely covered - you could see her puckered hole peeking from behind the cloth, her pussy lips engulfing the cloth and leaving nothing to the imagination. And from between her legs you could see and just make out one of her boobs, hanging down, her nipple visible and hard.
Mesmerised by the sight of my friend, exposed like a slut, I had already pulled out my cock and was furiously jerking it off - blissfully unaware of the girl next to me, stirring. As I was furiously jerking off, I was shocked out of my reverie to hear her say "Harsha". In my shock I dropped her phone, and cracked the screen. I turned to see her looking at my face, her eyes moving downwards to my cock, dripping precum, and my hand paralysed in fear. In a moment, I was filled with shame at what I had done, and there were no words in my mind to apologise. I was paralysed with fear, my hand gripping my now flaccid cock, and all I could think about was how my life was at an end, and my friend would tell everyone - my family, her family.
