A/N: I haven't updated in FOREVER! Ahhhh, damn school. Anyway, thanks to popular request (and way too much free time in chemistry) I present to you chapter two! It has a sex scene so be warned. It's got yaoi, so be warned. And it's got incest, so be warned. Anything else I should mention? Oh yeah, language and age differences. This is a flashback to Seto and Mokuba's first time. Third person PoV.

The young CEO glared at his computer screen, his breath quickening. Scrolling down to study the page closer, he glanced over his shoulder. No one was there to witness him at his weak point. He clicked the play button, his eyes focused on the video while his hand traced over the zipper of his jeans. He was too preoccupied to see his brother in the doorway.

"Fuck," cursed Seto, quickly leaving the room to wash up.

The pale child bit his lip and shakily sat in the chair. With wide eyes, he perused the website, reluctantly nodding his head in understanding. He pushed away a tear as he left his desk, feeling worse off. Why did he force himself to serve his brother like this?

"Come on, Mokuba," Seto called. "Time for bed!"

He searched through the hallways, eventually capturing the child in a tight hug as it melted into a quiet embrace. He tucked the boy into bed, stroking the black locks lovingly. The brunette turned to leave as an outstretched arm grabbed onto his shirt.

"Seto...wait!" the small voice cried out.

His brother stopped immediately, turning around to listen.

"...can you stay with me t-tonight?" he paused, nervous.

"Sure," he replied without a second thought, crawling over the boy to an empty spot on the mattress.

Mokuba took a breath as he felt an arm around him, "Big Brother," he whispered, his heart pounding, "I want to...to do those things with you," he quivered, the images still burning in the back of his mind.

The older boy coughed, startled. It was the last thing he had expected to hear.

"What things?" he asked, trying to steady his voice.

Seto had made it clear he didn't want the relationship going any further, but only to turn his blind lust into safety from corrupting Mokuba even more. It wasn't right, he was sick, twisted, he shouldn't have ever brought his little brother into this.

"Those things on your laptop, Seto," the child was near tears, begging to be mastered.

Rational conclusions were thrown far aside as the taller boy crept over him, embracing his lips hungrily. The boy trembled, holding onto his protector's waist. The older Kaiba desperately unbuttoned the child's think shirt, flicking his tongue on the pale, revealed skin.

Mokuba arched, digging his nails into the boy's back. These sensations were so new, so caring. He bit his lip, It can't be wrong, Big Brother, it can't! No matter what you say...

Crystal blue eyes pierced violet brown as the teenager attempted to calm his hand, rubbing it against the smooth silk. He grinned as the black-haired child let out a stifled moan, his touch becoming more confident. Each vulnerable squirm, every incoherent plea for more drove the brunette wild, bringing him closer to the forbidden edge. He shed the rest of the small boy's clothing, caressing his most intimate parts, grazing a kiss on the lips of his tainted innocence.

"D-don't stop, Seto," moaned the child as he tried to catch his breath.

The smaller Kaiba put all of his trust in his brother, as he was touched in all these different places. An anxious smile flickered over his face as he took of the cumbersome shirt, running inexperienced hands down his long, milky back.

The brunette pulled back after a fervent kiss, realizing that he needed something if they were to go any farther. He grudgingly got off the bed, making his way out the door.

"Where are you going?" he gasped, frantic as the taller boy left the room.

"Stay," he panted, ashamed of what he was doing.

This can't be happening, I'm not doing this. He won't remember, he'll be fine in the future; this is just another sick fantasy.

He returned with a small tube of lubricant in the doorway, stark naked. Mokuba swallowed uneasily, not meaning to stare at his brother's beautiful form. The child tensed as the bed creaked, feeling once more the sweat-glistened body under his own. He licked the boy's ear, nibbling on it lightly, his hot breath on tender skin promised, "I don't want to hurt you,"

Another wave of guilt, but it was too late now, "This will help," he whispered, shifting his hips against the child.

The brunette intermingled his hand in the thick black hair, capturing his lips him eagerly, preparing his brother with the utmost care. Mokuba groaned into the kiss, spreading his legs to grant better access. He looked once more into the child's eyes, still conscious enough to ask.

The Kaiba brother nodded weakly, "Please, Big Brother, make me yours," he wrapped his arms around the brunette; placing nervous kisses along his pale neck.

Seto felt the small boy tense as he entered a finger into him. He stroked his hair reassuringly as he entered a second appendage. The child winced in pain, tossing his head back on the pillows.

"Are you-"

"I'm fine," he responded, furious at himself for showing weakness.

The frail body shook as he pulled out of him. Mokuba whimpered as the brunette penetrated him. Seto murmured words of reassurance to the child as he shifted deeper, clutching his brother's waist. He began pulling in and out of him gently; the boy's eyes fluttered back, guttural sounds escaped from his pale lips at the heated friction.

He felt the pace quicken, his brother entwined with him as one, I'm closer than ever to you, brother, his messy hair rolled back and forth in pure ecstasy, And I never want to let you go...

Gasping, his felt the brunette shudder, releasing deep inside of him.

"Oh, Seto!" was all Mokuba could choke out as he came soon after, his voice drawling out in a moan.

The older Kaiba pulled out quickly, laying next to him, kissing him passionately in gratitude. The child tried to catch his breath as his brother brushed away the sweat-matted hair. He rested in his arms, leaning his head on the boy's glistening chest.

"You're so wonderful," the boy whispered with a conent smile.

The older teen stll needed time to recover as he wrapped his arms around the child.

He then asked, worried, "Are...are you happ, Seto?"

The Kaiba took a deep breath, an exhausted grin on his face,

"Yes, Mokuba," he held him close, "You're wonderful, too,"

A/N: Wow, I don't feel guilty :blush: Worth another chapter? In Seto's PoV. Goodness knows I have enough free time in Chemistry.
