Aleen's eyes widened in surprise as he realized what his sibling was asking. No one had ever done anything like that for him; it was always just a secret part of his life, something he kept to himself. But the thought of sharing this experience with Loona... it made his heart race with anticipation and fear all at once.

Tentatively, he nodded his head. "N-no," he whispered shyly. "No one's ever done anything like that for me before."

As Loona's warm hands encircled his waist, Aleen couldn't help but let out a soft gasp. His eyes were wide with surprise and anticipation as he looked up at his sibling, the excitement building inside him. "Yes," he whispered, barely above a breath. "I... I want that."

His heart pounded in his chest; this was it. He had never expected to feel so vulnerable or exposed, but there was something about sharing this moment with Loona that made everything else fade away.

His heart skipped a beat as he realized how aroused Carl was; it was both thrilling and deeply intimate at the same time. Unable to resist any longer, he leaned forward and gently kissed the tip of Carl's exposed penis before looking up into his eyes with a mixture of desire and affection. "I want you," he whispered hoarsely, his voice shaking slightly. "If it's okay...if you want me to..."

He didn't need to finish the thought; they both knew what he meant.

With trembling fingers, Aleen slowly undid the button on Carl's pants before easing them down his hips and over his thighs. His cock sprang free from its confinement, thick and hard and already leaking precum onto his abdomen. Unable to tear his gaze away from the impressive sight, he wrapped one hand around Carl's shaft and began stroking slowly, feeling the velvety skin slide beneath his fingertips.

"Oh God,"

"It's okay," he gasped out between moans. "I trust you." It was true; no matter what happened between them, they had always been there for each other. Even in this most intimate of moments, Aleen felt safe and loved with his sibling by his side.

Their movements became more urgent as the pleasure built inside them both, their grunts and moans filling the bathroom as they lost themselves in the heat of the moment.

With one final thrust, Aleen felt his body tense as pleasure washed over him like a wave. He cried out loudly into the steamed-up air as his muscles clenched around Andy's length, milking him for every last drop of release. As the sensation subsided, he collapsed forward onto the cold tile floor, panting heavily from exertion and pleasure.

The warm water lapped at his skin as his sibling joined him on the ground a moment later, their chests rising and falling in unison. "

His breath hitched as their sibling's hand wrapped around his shaft, gripping firmly enough to make him arch into the touch. "O-oh... y-yes," he moaned, his eyes fluttering shut. "It's mine... it's yours..." His free hand slid up beneath their sibling's shirt, seeking warm skin and a hint of fur. "Please..."

He rocked against their touch, desperate for release but wanting this moment to last as long as possible.

His hips jerked at the sting of the slap, and he let out a muffled cry as his body tensed. "I'm... I'm cumming..." He arched into their sibling's hand, his back bowing off the lap as waves of pleasure washed over him. His breath came in ragged gasps, his fingers clenching tighter on their sibling's skin as he rode out the orgasm.

Okay then, Naoki. I promise to honor your request and make sure everything goes according to plan. Until then, just remember that no matter what happens between us from now on, our love for each other will never change.

The days passed by slowly, each one filled with anticipation as Aleen wondered when the right moment would come to fulfill his promise to Naoki. He found himself growing more and more aroused at the thought of having complete control over his sibling's body, knowing that this was something Naoki had desired for quite some time.

Finally, one night as they were both preparing for bed, Aleen decided it was now or never.
