Ride the rod...

The stranger's eyes widened at the sight of Dave's enticingly enhanced physique in the straps. He couldn't wait to test the resistance capabilities of those thick leather straps. "Perfect," he said, brushing a hand over Dave's swelling bulge. "You're ready for your first lesson."

He led Dave to the center of a dimly lit room, filled with an assortment of BDSM equipment. The air was thick with the scent of leather and a faint tinge of sweat. A few amateur dominants and subs were darting in and out of the spaces, whispering and sharing knowing smiles.

"We're about to make your most primal desires come alive," he panted into Dave's ear, his cock stirring through his pants. "Tonight, you will be put through your limit."

The stranger feasted his eyes on the gasping Dave looking shocked and maybe a little scared as he assisted him onto a dark padded bench with a thick black strap at the center. "This is right next to your limit line, my friend, and it's called the 'riding the rod' position. Lift your legs up, spread them apart, and place your ankles over these padded bars. Here are your instructions - you must hold on to the straps with your hands. Keep your face forward, and next, try riding that rod. Unless your afraid."

Dave was terrified, but he didn't show his fear. Silently, he obeyed each move like a trained robot. His first glimpse at the black rod made him start to rethink this whole situation, but his lust won him over, as his heart raced and his cock throbbed waiting for what was next. He lifted his legs and planted his soles on the bars, widening them apart. In the split second he caught his breath, he tightened his grip on the straps before he began to lower himself onto the massive rod before him. "Awww... No... I can't... can't do this!" Dave balked even as the strange anonymous man approached him with a small brown bottle.

"Ohooo come on now... Don't wimp out now... Here take a little sniff of this it'll help." As Dave inhaled bitter chemical fumes he felt a intense head rush, his eyes rolling in his head for a moment. And then the next thing he knew that rod was pushing deep into his ass, the pain had been a brief flash through him, and then it was prodding something wonderful inside of him.

The stranger walked behind Dave and reached his hand out, gently stroking Dave's now crimson-colored ass. "You're doing fantastic, Dave. Imagine if the rod wasn't just a rod but a thick hard cock." he cooed, his voice sounding urgent. "Cum for it," the stranger whispered seductively into Dave's ear. "Cum for the rod."

As Dave heard those words, his adrenaline surged to a new level, aiding his body as it began to acclimate. Against all odds, he started bouncing lightly, gradually making the pain start to morph into pleasure. The stranger's hand now gently pinched Dave's nipple, twisting it enough to push him completely over the edge. "Cum for me, Dave," the stranger moaned, moving his hand from Dave's nipple to his rock-hard cock.

Dave rode the rod harder now, letting out a strained moan as pleasure replaced pain. His cock twitched under the stranger's hand, dripping with pre-cum. He was ready to cum, "I'm gonna cum!" Dave growled, his body tensing up just before he exploded, sending long ropes of cum flying across the room as he continued to ride the rod. His entire body quivered as he reached his peak, the sensation now overwhelmingly pleasurable.

The stranger was soon rewarded with Dave's warm cum splattering his hand and pants. He tightened his grip on Dave's cock, pulling it slightly as it throbbed with post-orgasmic spasms. "That was amazing, Dave. You have a lot of control. Not many can handle the pressure," the stranger complimented, his voice still brimming with lust. "Rest now, let's see if we can make it even harder for you next time."

Breathless and shaking, Dave slowly lowered himself off the riding rod, feeling the warmth and residual throbbing from his body's recent exertions. There was a strange sort of satisfaction in the soreness and the knowledge that he had been pushed past his limits. His mind raced, wondering how the stranger intended to make it any harder next time.

The stranger helped Dave off the bench and led him to a chair by the wall. "How did you feel, Dave? It's okay if you didn't enjoy it; at least you tried. You learn through experience, right?" he asked, his eyes tracing over Dave's flushed and sweat-slicked body.

Dave merely shook his head, a small smirk forming on his lips. "It was… intense," he confessed, still finding it hard to comprehend that he had just accomplished something so ****. "I didn't think I'd be able to handle it, but… I did."

The stranger smirked, pulling Dave into a tight hug. "I knew you could. You're stronger than you think, Dave. I'm looking forward to our next session. We'll go the extra mile."
