Harry wrapped his fingers around the base of his cock, his eyes suddenly averted towards the ground to glance over each blade of grass as though it were the most interesting thing in the world.
He gently tugged at his cock, not making any effort to disguise the reluctance in his movements.
The warm summer breeze danced across his bare flesh, yet instead of calming him, it sent a shiver coursing through his body.
He had to hurry up, the sooner he finished, the sooner he would be able to go home.
Harry glanced down at his cock, sliding his thumb over his slit before driving it in slightly.
"Look at me." Snape commanded, his voice piercing the darkness with an unanticipated amount of force.
Harry gasped as he instinctively responded, his large orbs instantly locked with Snape's dark eyes.
"Be a good boy Potter and do as you are told."
Harry's grip on his cock tightened as he began to pump himself at a more vigorous speed. Yet, it seemed as though Snape now had something else in mind.
"Sit." The older wizard suddenly commanded.
Harry moved his feet, soon feeling his heels slide out from under his buttocks. His cheeks collided with the damp grass, driving the buttplug in as far as the confines of his ass would allow.
The young wizard groaned as a spasm of pleasure rushed through his groin.
"Good." Snape smirked as he leaned over ever so slightly. His fingers were still gripping the leash.
Harry tilted his head slightly, was that enough? But he hadn't technically come yet. Was Snape going to reattach the leash to his collar?
Harry's body shivered once more as the cool leather danced over his nipple before descending further down his body. The leash only seemed to stop as it rested against his restless groin.
What was Snape doing?
He watched as the professor slid his fingers into his pocket before seamlessly withdrawing his wand.
He aimed it at the tip of the leash without hesitation. Within a moment the leather had bound upon itself, forming a loop. Then, as if of its own accord, it jumped at Harry's cock, encircling the tip before instantly tightening as though it were a noose.
Harry yelped in a mixture of pain and shock, yet the leash also gifted to him another sensation, pleasure.
Harry slid his fingers between his now damp testicles before encapsulating them. He squeezed them as his other hand continued to pump his cock.
He felt so close.
The hand gripping his testicles seemed to move off of its own accord as it released the globes before sliding over his hip and reaching for the butt plug. He never thought he would think this in his wildest dreams but it was no longer enough. He needed more. He wanted to feel entirely full, his gaze once again locked with Snape's eye, except this time he offered his professor a pleading look.
"What is the matter Mr Potter?" Snape raised an eyebrow, though there didn't seem to be much curiosity in his eyes. It seemed as though he already knew what was the matter with Harry, having instigated it himself.
"P-please." The younger wizard pleaded, his voice soft, yet his words seemed to be expelled with great effort.
"Please what?" A smirk grew ever so slightly across Snape's lips.
Harry's eyes darted to the floor, as though he were ashamed.
"Fill me up." He finally muttered, as though the words that issued from his lips were something vile.
Snape offered his student a wry smile, as though he had been waiting for Harry to get into this desperate state.
"As you wish."
With a flick of his wand, Snape had dragged a park bench towards them. Harry gasped as it stalled mere inches from where Harry was sitting.
"Get up."
Harry rose instantly before climbing on to the park bench as he assumed Snape had intended for him. He had his back to Snape as he knelt on the bench, his arms resting on the back support.
"Present yourself."
Harry's eyes narrowed as though he were trying to figure out a difficult maths question with no calculator.
Present himself?
With a seemingly impatient flick of his wand, Harry felt an invisible force encapsulate his ankles before feeling then torn far apart.
Harry's cheeks had spread apart in the process to reveal the plug seated inside his opening.
Snape's footsteps drew closer but Harry didn't turn around as his desperate fingernails clutched the seat back.
Within a moment he felt the plug being slowly withdrawn from his body. He ground his hips against the cold metal of the bench, the tip of his cock catching on the gap between metal bars.
Yet it felt so good.
He moaned as he continued to grind his cock against the cold metal.
He soon felt his body expel the last inch of plug, yet he found himself feeling strangely empty.
Harry barely had time to inhale his next breath before he heard a distinct swishing noise behind him. It resembled the distinctive sound of a wand. Was Snape casting another spell?
Harry didn't have time to finish that thought as something suddenly tightened around his wrists and ankles, binding him to the park bench.
He was unable to move.
The pressure on his ankles drew his cheeks further apart still.
He felt something warm brush over his opening before sliding over his testicles and embracing them.
A shudder ran through his body as he realised the 'something' was Snape's fingers.
"P-please." Harry whimpered, hating himself as the words left his desperate lips.
Before Harry could brace himself, he felt something warm press against his opening.
Oh gods how he needed this.
He groaned as all sense of shame evaporated from his body. He no longer cared if anyone was watching him from the trees, but he would never admit that a tiny part of him wished he was being observed.
Another pang surged through his groin.
Snape huffed a laugh before sliding his cock into the tight opening splayed before him. Harry felt as though his body was no longer his, it seemed to be acting of its own accord. He moaned, a noise that seemed to come from a monster kept deep within him, one he didn't know existed until this point. A warm wet fluid shot over his abdomen, he barely had time to catch his breath before feeling the bindings fall away from his wrists and ankles. His body slumped against the park bench as a sense of exhaustion fused with satisfaction consumed him.
A sudden jolt brought him back to the harsh reality of being entirely naked in the park as Snape yanked on leash, the end of which was still attached to the tip of his penis.
"This is your new collar, so you had best keep up on the walk home." Snape stated as though he were reading his words straight from an encyclopedia, a slightly amused smile tugged at the corner of his lips.
Harry never thought that he could think of anything worse than being dragged around by the neck except Snape had shocked him yet again.
The professor dragged his reluctant student across the clearing before reaching the edge of the road once more.
Harry struggled to keep up as he felt a dribble of warm fluid slip out of his ass.
It was this that did it.
It was this that made him truly feel like a slut.
"Come on Potter." Snape drawled almost lazily as he gave the leash another swift tug.
Harry obeyed without hesitation, though his eyes were drawn upwards. There was no doubt about it, the sky was lightening.
This wasn't good, but they couldn't be far away now, right?
Harry winced, praying he was right as his pace instinctively picked up.
A sense of relief consumed him as the familiar faded, shabby door came into view.
"Get inside." Snape commanded as the door flew open at a flick of his wand.
Harry obeyed without question, though he really didn't need Snape to tell him to go inside. There was, after all, no way he was staying out there.
Snape followed the young wizard inside, his eyes lingering on the pale fluid that was currently glicining as it seeped down Harry's thigh. He continued to follow him until he reached the shabby dining room.
"Wait here." The professor stated flatly before allowing his end of Harry's leash to fall to the floor.
In a flash Snape was gone. Harry wasn't sure what to do as he crouched down near the dining table until he was practically under it.
Harry didn't have to wait long as Snape's long sides soon came back into view.
"Eat up." Snape drawled as he lowered a bowl to the floor. Harry crept closer towards it, as though he had become a cat and were unsure if his master had given him his favourite food or not.
The younger wizard peered into the bowl, the sight of what looked like dog biscuits greeted him.
Surely Snape wasn't truly expecting him to eat this?
Harry's eyes rose until they met the professors, it seemed no matter how hard he tried, he couldn't shake the essence of pleading from within them.
"Come now Potter, don't be a bad boy. Or I may have to put you outside again."
Harry's eyes widened before darting, as though by instinct, back towards the food bowl.
The young wizard crouched forward before drawing his lips to the food.
