~A dirty taster to start
Now you'd look at this and say "damn, what a hung hunk". But what if I turn it around and this that's a 17-year-old with a mean attitude? Likelier than you think. Teens are hella hung nowadays - and this dude knows he's hot shit. He's got that throbbing hormonal boner tucked in his onesie, and it looks like it's going to tear the fabric apart with how angry it looks. That's puberty for you. Just imagine how many loads his dad has blown to his dick pics. I'd be astounded if my son was that hot.
—The story
"Who the fuck do you think you are, invading into my territory dude?" You thought to go to the park for some fresh air, but this delinquent who has nothing better to do but stand around and stroke the outline of his cock all day, targeted you, and thought to ruin your day.
Teenagers have a habit of making your fight or flight instinct kick in (after all, anyone at this age should not be underestimated, they can throw some mean insults...), but something about the wolf's unfounded rudeness struck a nerve in you, and you felt rage boiling up in your chest.
You walked up to him and firmly grabbed his bulge, not out of rage, but out of lust. (I mean, it's so fucking obvious he's packing, why not cop a feel before you go, right?)
"And who the hell do you think you are, talking to your elders like that?" Your words were so powerful that spit flung in his face. But the so-called 'tough guy' did not flinch. 
The wolf's voice was like venom in your ears. He sneered.
"Please. You look like you'd fall over from a gust of wind."
Your face was the picture of frustration, but your hand gripping his bulge told otherwise.
"Are all skater boys this hung?" You asked, your voice barely above a whisper. Suddenly, all of your built-up rage left you in the presence of this ridiculously hung delinquent. He's a 'skater boy' to be exact, and he guards the upper areas of the park. It's fortunate that none of his friends are around to watch an adult openly groping him. (Not because they'd call the cops mind you, but because they'd probably ask for a turn.)
The wolf's smile turned into something more lustful as he placed his hand around your wrist, firmly pressing it against his bulge. You felt the teen's cock visibly pulsate under your touch.
"I thought you knew everything, 'elder'?" He retorted back, causing you to huff in defiance and continue stroking his bulge. The wolf now had his hands by the sides of his hips as he got rubbed off by a stranger in public, your arm slinked around his back for support. He was ready for you to have full control over his crotch. Like a true teenager, he just wants to get off. And, like a true bored 23-year-old coyote who has nothing better to do, you'd gladly help him.
He didn't say anything to you as you got him off from rubbing his giant, straining bulge, only giving you a grunt of satisfaction.
"That feels good, man." He said, as if the whole 'being stroked off by a male stranger' thing was new to him.
"Glad to hear it," you whispered back, your tone of voice encouraging him to speak more.

The wolf unzipped the top of his onesie, exposing his bare white chest, ripped with muscle. The sight took your breath away.
You placed a hand on his chest then reached down to tongue at his nipple, making the so-called 'tough guy' dissolve into boyish moans. He's already starting to show his age. But age won't matter to you when this cocky little shit is hauling around an 8-inch monster, probably bigger than his father.
The wolf, starting to get riled up from all this action, unzipped his onesie further down and stroked his semi hard cock, now exposed in the night air. You watched with wonder in your eyes as the boy's foreskin rolled back and forth along his veiny, untouched, uncut shaft. It was gigantic. Whatever his parents were feeding him, it was good stuff. (But, as we all know, he's only got his father to thank for that fat fucker between his legs!)
When you beat his hand away to wrap your own around his cock, the wolf moaned again, but this time more out of surprise. His cock pulsated in your grip and it felt very warm. You continued the strokes, being a little slower than what he was, and continued to kiss at his chest and stomach.
"Should've known you were some kind of predator." He wryly responded, breaking the lustful silence - naught but moans and gasps escaping from your mouths now.
"Shut up," you replied, then proceeded to suck at another nipple, causing the lean wolf to shake and buckle his body in desperation.
"It's all new to me," he gasped.
"I know baby. I know."
"I feel like I'm about to burst at any moment," he confessed again.
You didn't respond. The only thing you did was break away from his chest, soaked with your eager, and lean against your arm, which was supported by the tree trunk.
Now your full attention was focused on the skater boy's throbbing, inexorable cock.
You resumed your strokes, firmer and faster than before. You used your other arm to wrap around his lower back, supporting the wolf's balance. His tongue hung out of his mouth and sweat fell down his face. You felt like very much the same as him. Extremely turned on.
"Now I didn't know we had hung kids in our neighbourhood," you spoke, your voice husky, laced with lust.
"But if it wasn't for your fat fucking dick, that bratty attitude of yours would've gotten you a knuckle sandwich."
You looked at the wolf, and he looked back at you. You couldn't see much with his hood pulled up and his hair covering his eyes, but his body language spoke enough. He's ready for anything you want.
"But, by Christ, you're beautiful."
You moved in for a kiss and the boy accepted by firmly planting his hand by the back of your head. He must be used to girls coming into him like this. Not 23-year-old men who have nothing better to do.
His cock exploded as soon as he forced his tongue down your throat. His rich sperm coated the tree, covering the trunk in ropes of white. Boys these days - they've gotta disrespect their surroundings. But there's no sugar coating it, this 17-year-old hung skater boy has a fat dick and an open mind. The fact that you give the best handjobs and the most lustful kisses is just something he's found out by sheer good fortune.
He broke the kiss away, licking the residual spit with his lips.
"I go to Forkhills High," he said, causing you to blush and chuckle nervously.
"I'm not sure if I should know that," you responded, the guilt settling in.
You felt his hand on your shoulder.
"Why? At least you know where to go if you wanna get some good dick." He said, his voice raising to sound more like himself, and not like the whole 'tough guy' act he was putting up.
You looked at him, amazed.
He smirked, looking as smug as ever.
"Heh. Lunch time is when I get horny."
He shook the last few drops of cum from his cock, put his finger in his foreskin, and licked up the rest of the watery spunk from his hand.
"See you around, pedo." 
Your heart sunk.
"Hey, I'm not a pedo!" 
The wolf turned around, stretching his arms behind his back, standing straight. You noticed how his bulge was expanding in his nether regions - the dude's probably gonna have a stiffy again in the next 30 minutes.
"Sure you ain't. But you don't even know my name."
"W-William!" You shouted out.
"That's... That's my name." You explained.
The wolf breathed through his nose, pulling his hood to the side to hide his smile. He waved you off.
"Just call me... HungTwunk1269."
He looked at you again, trying desperately to hide his genuine smile.
"See you." He said softly with a raise of his hand, then raced back home.
You were left alone in the night with a massive boner. You also raced back home, in the opposite direction.
