**Marked and Claimed**

Sirius's eyes blazed with desire as he gazed at Regulus, his hands roaming over the younger man's body as if claiming ownership. The air was thick with tension, heavy with anticipation, as Sirius's fingers trailed down Regulus's spine, sending shivers down his back. "Time to take our relationship to the next level," Sirius whispered, his voice husky with arousal. He grasped Regulus's hips, spinning him around to face the mirror. Regulus's eyes met his own reflection, and he felt a flush rise to his cheeks as Sirius's hands began to undress him. The corset and panties were quickly discarded, leaving Regulus standing in front of the mirror, his body exposed and vulnerable. Sirius's hands returned, this time grasping Regulus's hips and bending him forward, his chest pressed against the mirror. Regulus let out a gasp as Sirius's cock pressed against his entrance, the head slowly penetrating him. It was a slow, gentle invasion, but Regulus still felt a twinge of discomfort. Sirius's hands held him firmly in place, his fingers digging into Regulus's hips as he began to move, his strokes growing stronger and more insistent. As Sirius sated him with his cock, Regulus felt a wave of pleasure wash over him, his body relaxing into the invasion. The mirror fogged up, reflecting a distorted image of his own face, his eyes closed in ecstasy. Sirius's breathing grew heavier, his thrusts more forceful, as he reached for a small tattoo machine on the nearby counter. The buzzing noise made Regulus jump, but Sirius's hands held him firmly in place. The needle began to move, scratching out a pattern on Regulus's lower back, just above his ass. The pain was sharp, but Regulus barely noticed, his mind focused on the sensations coursing through his body. The words "Property of Sirius" began to take shape, the letters bold and unyielding. As Sirius finished the tattoo, he let out a groan, his body shuddering with release. Regulus felt him spill his seed inside him, the warmth spreading through his body like a brand. Sirius's hands released Regulus's hips, and he slowly withdrew, his cock slipping out of Regulus's body. Regulus stood up, his body trembling, as he gazed at his reflection. The tattoo was a stark reminder of his new status, a symbol of his submission to Sirius. The mirror reflected a person who was no longer the same, a person who was now marked and claimed by Sirius. Regulus's eyes met Sirius's, and he saw a glimmer of satisfaction, of possession, in his gaze. "You're mine now," Sirius said, his voice low and husky. "Forever and always, you'll be mine."
