Doggy in: Night of chemsex in Old Town

It's eleven at night when you receive the message: "Apartment in Somera. Third floor without an elevator. Ask for Iker." Your heart beats strongly as you walk through the narrow streets of the Old Town. The wet stones reflect the streetlights, and each step brings you closer to what you know will be a night of complete degradation.

You climb the creaky wooden stairs. The smell of humidity mixes with something more... chemical. You knock on the door, and Iker, a man in his forties with a thick beard and glassy eyes, already high, opens it.

"You're late, puppy. The others have already started."

He pushes you inside. The apartment is small, typical of the Old Town, but the atmosphere is charged. Four other men look at you from the living room. A glass table in the center with lines already prepared, poppers scattered around, and the unmistakable sweet smell of melting crystal.

"This is the cumdump for tonight," Iker announces as he takes off your shirt without ceremony. "Isn't that right, puppy?"

You nod with your head down. Mikel, a burly Basque man with tattooed arms, gets up from the couch with a twisted smile.

"Let's start with this," he says, pointing to the table. "Get on all fours and lick a line from my navel."

You position yourself as he orders. Mikel lies down on the couch, pulls down his pants, and draws a line from his navel to the base of his already hard cock. The crystal shines on his dark, sweaty skin.

"Good puppy. Now suck it while the others get you ready."

You feel hands on your ass, someone pulls down your pants with a jerk. Jon, a young man in his thirties with a construction worker look, spits on your hole.

"Damn, what a tight ass. We're going to break it in well."

While you have Mikel's cock down your throat, Jon inserts two fingers abruptly. There's no lubricant, just saliva and desire. The pain electrifies you, mixed with the high from the crystal.

"Give him a pass before he enters," says Asier, the youngest, a dark-haired man with a goatee. He brings you an open popper to your nose. "Breathe deeply, puppy."

One, two, three deep breaths. Your head spins, your muscles relax, and Jon takes advantage of it to thrust his cock inside you. You scream, muffled by Mikel's cock in your mouth.

"I like it when you scream," Jon laughs as he fucks you mercilessly.

Xabier, the fifth man, a bald, beer-bellied man in his fifties, stands in front of you with a small syringe.

"Have you ever tried this, little one?"

You shake your head, your eyes tearful from the effort o...
