My first crush at school was a girl called Rebecca. She was considered a swot, and wasn’t the most popular girl in the class, but Rebecca had many redeeming qualities, a least as far as I - a horny teenaged boy - was concerned

Firstly, physically. Most boys thought she was too boyish to be sexy and, to be honest, she was skinny as a rake with a chest as flat as a pancake. She was quite tall for a girl, around the same height as me, with gorgeous skinny legs that started at her slim ankles and ended at her pert little ass. A tiny waist, an almost completely flat chest, a pretty face with small features and a head of light-blonde hair. Her skinny little body drove me nuts with desire.

Secondly, her nerdy side meant that Rebecca was curious about everything - intellectually and, luckily for me, sexually. Things started a couple of days after a sex education class at school, when she rang me to ask how erections work - “Is there a bone that slides in to make it hard, is that why it’s called a boner ?”. I told her it was hard to explain and that she would have to see for herself, and so she told to come over the next day while her parents were at work.

When I arrived, she had obviously spent the night thinking deeply about penises and she bombarded me with questions as though we were revising for a science exam. Not entirely satisfied with my answers, she soon decided that a practical examination would be more enlightening - “Can I see it?”, she asked. Eager to please, I undid my trousers, pulled them down to my ankles with my boxers and sat slightly awkwardly on the sofa. Rebecca knelt in front of me and began to look at me closely, while asking still more questions - “Is it normally that size? Why are the balls so wrinkly?”. Finally, after staring at my penis intently for a few minutes, she uttered the words every teenage boy wants to hear - “Can I touch it?”.

That was the first time somebody else had touched my cock and so she got a very rapid demonstration of how erections form. Her fingertips had barely touched my balls when my soft little penis began to expand and stiffen. By the time she began to gently touch the shaft, now standing up in front of her, I was already rock hard and feeling extremely excited. “What do you do when you play with yourself?”, she asked, and so I showed her how to hold me. Extremely turned on by this time, no sooner had she squeezed me with her hand and begun to stroke me, she was given a demonstration of ejaculation as my cum squirted all over my shirt. Still holding me, she observed with interest as my cock let out another squirt of cum and my cock started to lose its stiffness. Seemingly content with the demonstration, she sent my heart racing as she asked “Do you want to see me?”.

I nodded shyly and Rebecca stood up, unbuttoned her skirt and let it drop to the floor, before sitting down on the sofa. I knelt down, looking at her smooth, skinny white legs stretched out in front of me and, more importantly, at the mound inside her panties which I was about to discover. I reached up hesitantly and took hold of her little white cotton panties, and began to pull them down as she lifted up her bottom and then, as I pulled the panties over her feet, spread her legs so that I could take in the wonderful sight before me. Her short blonde pubic hair was almost transparent, allowing me a view of her beautiful little pussy. The outer labia were almost as pale as her legs while, between them the light-pink edges of her inner labia peeked out. Below I caught a glimpse of the pink rosebud between her buttocks. As I stared at the wonder before me, I felt a tingling in my balls, and a little drop of cum dribbled onto my thighs.

I slid my hand slowly up along her lovely smooth thigh until I felt her pubic hair ticking my fingers. After a moments hesitation I gently stretched out my hand and began to gently touch her pussy lips, feeling the different textures of skin under my fingers. After a few minutes of exploration, Rebecca reached down and guided my fingers to the more interesting destinations, moving my fingertip in little circles around her clitoris, then sliding it down between her wet labia until my finger was at the entrance to her vagina. As she slid my finger inside her warm, wet pussy, the incredible sensation was too much for me and, with a shiver, my cock started squirting cum as Rebecca giggled with pleasure.
