The drinking session went on for quite a while.
Harry drank more than usual because he was happy to reunite with his younger brother after so long.
Mike, who had just been discharged from the military and returned home, kept refilling Harry’s glass with a smile.
But Harry had no idea.
Mike had secretly spiked his drink with a special drug, little by little, from the very beginning.
“Hey, let’s go for round two. I know a quiet place nearby.”
Mike smiled as he spoke. Harry nodded and stood up.
“Yeah… I’ll go to the bathroom real quick.”
Harry staggered toward the bar’s bathroom.
Just as he finished urinating and was about to leave, a sudden wave of intense heat surged through his body.
His vision blurred and his legs trembled.
“Ugh… what the hell…”
He tried to hold onto the wall, but collapsed on the spot.
---
How much time had passed?
Harry slowly opened his eyes under the dim lighting.
It was a dark hotel room. A dull pain throbbed in his wrists and ankles.
The moment he realized his hands and feet were tightly bound with rope, cold sweat broke out all over his body.
“…Mike?”
At that moment, a massive shadow slowly emerged from the darkness in the corner of the room.
It was Mike.
Harry was so shocked he almost forgot to breathe.
Mike’s body had already surpassed human limits.
Broad shoulders, explosively swollen chest muscles, thick arms, sharply defined abs, and powerfully muscled thighs—all of it glistened under the light, twitching with raw power.
And the most overwhelming sight of all was——
Mike’s enormous cock.
Even after cumming several times already, thick white semen was still continuously flowing from the massive shaft, dripping onto the floor.
The heavy cock swayed left and right, and his balls looked bigger than two large melons combined, hanging heavily below.
Mike approached slowly with a smile on his face.
“You’re awake? Harry… I think I gave you too much. You were out for a while.
You already came five times before you woke up… but I’m still nowhere near satisfied… hehe.”
Mike began slowly caressing Harry’s body.
He stroked his chest, abs, and thighs, then pulled down Harry’s pants and underwear.
He took out Harry’s originally tiny cock—which had always been less than 6cm—and immediately swallowed it deep into his mouth.
“Ugh…! Hey… what are you doing… please… stop…”
Harry twisted his body and begged.
He had always been deeply insecure about his small size, and being tied up and exposed like this in front of Mike filled him with unbearable shame, making his face burn red.
Mike, still sucking, looked up with a grin and said,
“You look so cute like this, Harry.”
With just a few skillful swirls of his tongue, Mike completely stimulated Harry’s tiny cock.
Harry’s body trembled uncontrollably, and he came instantly inside Mike’s mouth.
“……!”
Mike swallowed every drop without spilling any, then pulled away from the now limp little cock.
“Tastes good, Harry… but it’s a shame it ended so quickly.”
Mike took out a small syringe from his pocket.
The moment he injected it into Harry’s arm, an intense heat spread throughout his entire body.
“Ugh…! What… what is this…!”
Harry’s cock began twitching again.
It swelled rapidly, soon growing well past 50cm.
Mike grabbed the massive shaft with both hands and began stroking it slowly.
“Haa… haa… please… stop…”
“You’re still far from done, Harry. Cum more for me.”
Mike’s hand moved faster and faster.
Harry came again and again, and with each orgasm his cock grew even bigger and harder.
After several climaxes——
His cock surpassed 80cm, and at the same time, his entire body’s muscles began to twitch violently.
His chest swelled, his arms bulged, his thighs thickened.
The bed creaked under his rapidly increasing weight.
“Uaaah…! My body… something’s wrong with my body…!”
Harry writhed and moaned while still bound.
Mike watched with a satisfied smile, continuing to toy with him—stroking the huge cock, groping his chest, pinching his nipples.
“Ah… please… it’s too big… I need to cum… please…”
Tears welled up in Harry’s eyes.
Shame, pleasure, and guilt swirled together, turning his mind blank.
Mike chuckled softly.
“You want to cum that badly, Harry?”
Harry begged, almost sobbing.
“Please… anything… front or back… just fuck me… please… I can’t hold it anymore…”
Mike continued tormenting him for a long time.
Harry came countless times while bound, his body and cock growing larger and larger.
Eventually, his physique completely overpowered Mike’s.
At that moment, the drug’s power amplified explosively inside Harry’s body.
While the drug affected people differently depending on their constitution, Harry was special.
His cock instantly shot past one meter, easily surpassing 1.3 meters.
His muscles also exploded in size, already overwhelming Mike.
“……!”
The moment Mike’s eyes widened in shock, Harry tore through the ropes binding his wrists and ankles with raw strength.
He roughly flipped Mike over and pinned him down.
“Now… I’ll make you feel good.”
Harry growled in a low, rough voice as he grabbed Mike’s waist with both hands.
He effortlessly lifted Mike’s muscular body and thrust his overwhelming cock deep inside in one powerful stroke.
“UAAAAAAGH——!!”
Mike’s scream filled the hotel room.
Harry’s 1.3-meter monster completely stretched and filled him, making his stomach bulge visibly.
Harry clenched his teeth and began pounding wildly.
*Thwack! Thwack! Thwack! Thwack!*
“Ugh…! Harry…! It’s too big…! Aaaagh…!”
Mike trembled and moaned, but Harry didn’t stop.
He thrust even harder and deeper, gripping Mike’s waist tightly.
“Haa… haa…! Harry…! Too rough…! Ngh…! I’m gonna… I’m gonna cum…!”
“Not yet…!”
Harry flipped Mike onto his back and drove in even deeper from above.
Mike’s stomach bulged obscenely with every thrust.
Harry groped Mike’s massive chest with one hand while stroking his huge cock with the other.
*Thrust! Thrust! Thrust! Thrust!*
Finally, Harry let out a deep growl as he reached climax.
His 1.3-meter cock throbbed violently, flooding Mike’s insides with thick, hot cum.
At the same moment, Mike, overwhelmed with pleasure, bent his own massive cock toward his mouth.
While still being fucked, he greedily swallowed his own enormous shaft deep into his throat and sucked frantically.
*Slurp… gluck…!*
Mike sucked himself off while getting pounded, eyes rolled back, and came at the same time.
Their combined semen exploded outward, soaking the sheets, floor, and walls.
The entire hotel room was filled with the thick smell of sweat, cum, and raw male musk.
Harry kept his still-hard cock buried deep inside Mike and whispered roughly into his ear.
“We’re not done yet.
Tonight… I’m going to fuck you properly.”
