Alex's footsteps echoed through the quiet hallway as he approached his apartment, the weight of his day pressing down on him. He fumbled with his keys, eager to collapse onto his bed and forget about the world for a while. As he pushed open the door, the silence was shattered by the sound of giggling coming from his bedroom. Confusion mingled with irritation as he stepped inside, setting his bag down with a thud.

"Jamie?" Alex called out, his voice tinged with concern. The giggling stopped abruptly, replaced by hurried whispers. Curiosity piqued, Alex moved towards his room, his steps hesitant yet determined. Pushing the door open, he was met with a sight that both shocked and aroused him—Jamie and Chris, tangled in sheets, their faces flushed and hair disheveled.

"Oh, Alex, we didn't hear you come in," Jamie stammered, trying to cover herself modestly with the blankets. Chris shifted awkwardly beside her, a mix of embarrassment and defiance in his eyes.

Alex stood frozen, his gaze drifting past them to the rumpled bedsheets, where droplets of cum glistened in the dim light. His mouth went dry, and a strange thrill coursed through his veins. Without thinking, he took a step closer, his eyes fixated on the evidence of their passion.

"I... I should go," Chris mumbled, grabbing his clothes and hastily dressing. Jamie watched him, her expression a mix of relief and lingering desire.

As Chris left, Jamie turned to Alex, her cheeks still flushed. "Look, we didn't mean to... It just happened."

Alex nodded, his mind racing. He couldn't tear his eyes away from the pillow, now marred with streaks of white. A forbidden thought crept into his mind, urging him forward. With a shaky hand, he reached out, his fingers brushing against the damp fabric.

"Alex, what are you doing?" Jamie asked, her voice soft with concern.

Ignoring her, Alex leaned down, his tongue darting out to taste the residue. The salty-sweet flavor exploded on his tongue, igniting a fire within him. He closed his eyes, lost in the sensation, his body responding in ways he couldn't explain.

When he opened his eyes, Jamie was watching him, her expression unreadable. "Why did you do that?"

Alex swallowed hard, his voice barely above a whisper. "I don't know. It just... it called to me."

Jamie bit her lip, her eyes flickering with something akin to understanding. "Maybe we should talk about this."

But Alex shook his head, his mind already plotting. "No, it's fine. Just... let me clean up."

As Jamie retreated to the living room, Alex lingered, his gaze sweeping over the room. The idea formed slowly at first, then grew into a plan. If he couldn't stop them from using his bed, perhaps he could use their actions to fuel his own desires. A voyeur, a participant in secret.

Days passed, and each time Jamie and Chris were together, Alex found himself drawn back to the scene. He watched from the shadows, his body tense with anticipation, his mind focused on the climax, the moment when Chris would spill his seed. And each time, he waited, biding his time until they left, then pounced on the bed, licking, tasting, consuming every drop.

One evening, as he knelt by the bed, his tongue working feverishly, a sudden thought struck him. What if he didn't have to wait? What if he could be part of the action, right from the start?

The next night, as Jamie and Chris began their ritual, Alex stepped out of the shadows, his presence unexpected yet strangely welcome. Jamie gasped, her eyes wide with surprise, but Chris merely smirked, his eyes glinting with mischief.

"What are you doing here, Alex?" Jamie asked, her voice wavering.

Alex met her gaze, his resolve firm. "Watching. Participating. Whatever you'll allow."

Chris chuckled, leaning back against the headboard. "I like where this is going."

Jamie hesitated, her eyes darting between them. "Are you sure, Alex? This is... intense."

Alex nodded, his voice steady. "I'm sure. Let me show you."

With that, he moved closer, his hands gentle yet commanding as he helped Jamie out of her clothes. Chris watched, his eyes alight with excitement, as Alex guided Jamie into position, his lips finding hers in a passionate kiss.

The room filled with the sounds of their breaths, heavy and ragged, as Alex took control, his every move calculated to heighten their pleasure. Jamie moaned beneath him, her body arching instinctively, her trust absolute.

As the tension built, Alex felt the familiar rush, the culmination drawing near. He positioned himself, his eyes locked with Chris', and with a final thrust, he released, his seed mingling with Chris' on Jamie's skin.

Breathless, Alex collapsed beside Jamie, his heart pounding in his chest. Chris leaned over, his hand resting on Alex's shoulder, a grin spreading across his face.

"That was... incredible," Jamie whispered, her eyes shining with satisfaction.

Alex smiled, his body still humming with energy. "It was just the beginning."
