"Are you sure?" Mei asked quietly, her heart racing as she considered the implications of what he was asking. She wanted to make him feel good, but she didn't want to cross any lines or lead him on in any way.

Sola nodded eagerly against her shoulder. "Please..."

Tentatively, Mei began to stroke his softening erection again, her movements slow and gentle. As he grew more relaxed beneath her touch, she allowed herself a small sigh of relief.

Mei continued to touch Sola that night, guiding him through another orgasm and helping him learn about the new sensations his growing body could experience. Despite the strange feelings it brought up within her, she found comfort in being there for him during these moments of discovery.

As they lay together under the covers afterward, holding each other close, Mei couldn't help but wonder how much more change there would be in store for them both as they navigated the tumultuous world of adolescence.

Finally, their lips parted, and they gasped for air at the same time, panting heavily as they looked into each other's eyes. The connection between them was palpable, almost tangible, and it seemed to fill every inch of the room. Slowly, Mei reached up and brushed a stray strand of hair from Alex's forehead, her fingers trembling ever so slightly.

"Wow," she whispered hoarsely. "I didn't know...that it could be like this."

Alex looked at his older sister with an expression that combined shock, awe, and pure desire. "Neither did I," he confessed softly, his voice still rough from their exertions. Their gazes locked for what seemed like an eternity, each lost in the other's eyes, before finally breaking away as they both realized where this was leading.

"We should probably stop," Mei said slowly, her voice shaky and uncertain. "This is wrong...and we shouldn't be doing it."

Her breath catches in her throat at the thought as she feels herself nearing the edge again. "Please..." She whispers hoarsely, arching her back to meet each of his thrusts. Her fingernails dig into his shoulders, leaving trails of red behind as she holds on tightly, desperate for release.

Her hips rock up against him, wanting more of him inside her with every passing second. "I need you... Miyoko..."

Her breath comes in ragged gasps as he thrusts deeper inside her, filling her up completely. She can feel herself on the brink once more, the pressure building within her until it threatens to overwhelm everything else. Her fingernails scrape down his back, leaving trails of blood behind her as she tries to get closer, deeper into him.

"I need you... Miyoko..." The words are little more than a whispered plea, her body trembling with anticipation and desire.
