Uncharted Desires

Sirius's hands reluctantly broke the kiss, and he stepped back, his chest heaving with exertion, his eyes gleaming with a mischievous spark. Regulus's eyes fluttered open, his face flushed with desire, his lips still swollen from the intensity of their kiss. "Bend over," Sirius growled, his voice low and husky, his eyes burning with a fierce intensity. Regulus's eyes widened, but he didn't hesitate. He bent over, his hands grasping the bale of hay in front of him, his body trembling with anticipation. As Regulus assumed the position, Sirius's gaze roved over the younger man's body, his eyes lingering on the curve of his ass. The sound of hooves echoed through the stable, growing louder with each passing moment. Regulus's head lifted, his eyes peeking over his shoulder, a look of uncertainty on his face. Sirius's smile grew wider as he nodded towards the stall door. "It's okay," he whispered, his voice reassuring. "I want this. I want you to experience this." The stall door creaked open, and a majestic black stallion stepped out, its eyes gleaming with curiosity. Regulus's eyes widened as the stallion approached, its nostrils flaring as it sniffed the air. Sirius reached out, stroking the stallion's neck, his voice soft and soothing. "It's okay, boy. She's willing. She's ready." The stallion's ears pricked up, and it moved closer to Regulus, its eyes fixed on the younger man's body. Regulus's face was flushed with excitement and fear, but he didn't move, his body trembling with anticipation. The stallion's hot breath washed over Regulus's skin, and he shuddered, his body tensing. The stallion's cock slid out, and with a swift motion, it mounted Regulus, its body covering the younger man's. Regulus's eyes went wide, and he let out a soft cry as the stallion began to move, its body pistoning in and out of Regulus's pussy. Sirius watched, his eyes gleaming with excitement, his body tense with desire. The stallion's hooves pounded against the stable floor, and Regulus's body trembled, his face twisted in a mixture of pleasure and pain. Sirius moved closer, his hands reaching out to stroke Regulus's back, his touch reassuring. As the stallion continued to ride Regulus, Sirius's eyes locked onto the younger man's face, watching as his body adapted to the invasion, as his face contorted in a mixture of pleasure and surprise. The stallion's movements grew more frenzied, and Regulus's body trembled, his voice hoarse from crying out. The stallion let out a loud whinny, and its body stiffened, its cock pumping deep into Regulus's pussy. Regulus's body trembled, his eyes fluttering closed as he let out a soft cry, his body shuddering with release. Sirius's eyes gleamed with satisfaction as he watched Regulus's body convulse, his face twisted in a mixture of pleasure and exhaustion. The stallion stepped back, its body still heaving with exertion, and Sirius moved closer, his arms wrapping around Regulus's waist, pulling him into a gentle hug. As they stood there, surrounded by the quiet of the stable, Sirius knew that this was just the beginning of their journey into the uncharted territories of their desires.
