It was the summer vacation and my parents were at work. I was sunbathing in the backyard, laying semi-prone on a lounger by the pool and wearing just my shorts.
The wooden deck on my side of the pool was not overlooked by any other house. On three sides of the pool a high concrete wall on the boundary encloses it, with our house doing the same on the fourth.
It was either the warmth of the sun or the tight grip of the shorts that made my cock start to rise. I felt a pleasant and gradual swelling – a sensation of elasticity with reserve for even more growth. It wasn't until the foreskin started peeling back I realised I had tightened my butt muscles to enjoy an increasingly delightful self-arousal.
Even though I knew no one could see, I looked around to be sure. It wasn't the first time I'd decided to jerk off by the pool but it's not something you want the embarrassment of being caught out doing.
My cock felt smooth and sensitive after I slipped my hand inside the waistband of my shorts, the overall stiffness growing as I pressed the shaft and cupped the head with my fingertips.
The shorts became constricting, keeping my cock from rising. Lifting my butt, I pushed the waistband down until my cock sprang free. The elastic came to rest gripping the underside of my balls.
Gripping my hardened prize, with the foreskin peeled right back and the head swollen to three times its normal size – or so it looked – I was about to start jerking-off when I heard a stifled giggle. Panicked, I tried unsuccessfully to cram my huge boner back in my shorts. Julie, the girl from next door, was leaning on top of the wall, looking down at me.
"So this is what you do when you're alone," she said.
At eighteen, she was the cutest blonde chick in our high school cheerleader squad. It was bad enough she'd caught me at it, worse that I couldn't get my cock to go soft enough to fit back in my shorts. I wanted to sink into the ground and never show my face at school again.
"Don't put it away," she said when I tried to again.
"What?"
"I'd like you to leave it out for me to see."
I stopped struggling with it, wondering if she was making fun of my predicament. She added, "I didn't mean to stop you doing what you were before."
My face started to burn.
"It's okay," she said with a sweet smile that made me feel even stiffer. "I know guys like to do that to themselves."
Julie – not only popular but a year ahead of me at school – had always seemed unattainable. I'd never expected she'd talk to me, let alone be in a situation where'd she see my proudly sprouting cock.
"What are you doing up there?" It was all I could think to say.
"I climbed a ladder to pick some grapes." She brushed a blonde fringe back from her dark blue eyes. "And I saw something else that was really ripe." She giggled sexily. "I rather like it."
It was the last thing I expected to hear any girl say, let alone Julie. It was stimulus enough to make me clench my butt cheeks again, trying to make sure my cock looked as stiff as it could for her, wanting to show it at its best.
"Oh my," she said, "that really is big."
No other words could have been sweeter to my ears.
"I like watching you touch it," she told me.
"Like this?" I made it bob around in my fingers.
"Oh yes!" Her blue eyes were big and round.
I got the impression, even with her looks, it was the first time she'd seen a penis other than in a flaccid state – and then probably only her little brother's. I couldn't imagine a guy's remaining like that in her company for long. I thought, hopefully, that all the guys in her year might think she was way out of their league too.
Either she didn't date much or she was a nymphomaniac, I speculated. I wasn't sure what that was, but I'd heard other guys refer to girls as nymphos if they reckoned they liked sex a lot – something that didn't make them crazy in my eyes.
"Can I come down there and watch?"
"Watch?"
"While you jerk off – you know."
"I wasn't going to do that," I lied.
"Oh." She looked disappointed.
"I could do it if you wanted me to."
"Will you go all the way?"
I knew she meant me, not us. I nodded, holding my cock in a preparatory way.
She climbed on top of the wall then lowered herself down to my side. Her legs were long, tanned, and bare coming out of tight shorts. She had, I saw, when she turned round, tied the ends of her shirt in a knot baring her midriff. She looked at me, shy from being so close, and hesitated about leaving the base of the wall.
"It doesn't bite," I said.
"Does it bark?" She giggled cutely.
"It just spits like a cobra," I blurted proudly.
"That's very bad-mannered of it," she teased.
"I thought seeing it spit was what you wanted?"
"I hadn't thought about it in those terms." She sounded very mature. "I'd pictured it more like a fountain."
"I spits," I asserted. "Like lava out of an exploding volcano."
She hugged herself theatrically. "That gives me goose bumps!"
"Are you going to come any closer?"
"No. I don't want to get any hot lava on me when it erupts." She couldn't seem to take her eyes of it. "What do you have to do to make it spit?"
"Milk it like this," I demonstrated.
"It hasn't happened."
"I'm holding back."
"Why?"
"Because I like you looking at it."
"I shouldn't be." She seemed to be having qualms. "You'll get the wrong impression about me."
"I won't tell if you won't."
"It can be our secret." Her eyes were warm and intimate. It made me feel as if we were in a relationship. I was prepared to do anything for her.
She seemed to like it when I pumped my cock some more. She stared at my manhood and I stared at her bare midriff and the crotch of her shorts. She stepped closer, as if mesmerised, and finally sat on the end of the lounger near my feet. "Can I touch it?"
I took my hand away immediately to give her full access. My cock stayed upright by itself in anticipation. She reached out and tentative fingertips touched the head where fluid had leaked out. Her hand flicked back, as if she'd made contact with a live wire. She giggled nervously.
"I've never touched one before – except my little brother's – with a flannel when I'm washing him in the bath."
"You can hold it in your hand if you like."
She shook her head. "I'd get grounded for life if my parents found out I'd even watched you."
"Mine won't be home for hours."
"Nor will mine."
We grinned at each other then looked back at the swollen organ that had brought us together.
"Can I really hold it?"
"If that's what you'd like," I tried hard to be polite. I couldn't believe it was happening – not with the prettiest girl in school and not with my cock out in front of her.
"You won't – you know – if I do?"
"Not if you don't want me to."
She wrinkled her nose. "I don't know if I should..."
