Chapter 28: The Valley of Oil and Sin
"Take them off."
The permission hung in the air, thick and heavy like the scent of the sesame oil warming in Kai’s hands. Ye Rou didn't move. She lay face down, her face buried in the pillow, her breathing shallow and rapid. She had surrendered. She had given him the key to the final gate.
Kai didn't hesitate. He didn't want to give her a single second to rethink, to let the shame creep back in.
He hooked his thumbs into the elastic waistband of her white cotton panties. His knuckles grazed the soft, warm skin of her hips.
"Lift up slightly, Mom," Kai commanded softly.
Obediently, Ye Rou raised her hips an inch off the mattress.
Kai pulled.
The white fabric slid down. It dragged over the curve of her buttocks, revealing inch by inch of pale, milky flesh that had likely not seen the light of day—or the eyes of a man—in years. He pulled them down over her thighs, past her knees, and finally off her ankles.
He tossed the panties to the floor.
Ye Rou lowered her hips back onto the bed. She was completely naked now.
The sight was enough to make Kai’s mouth go dry.
Without the compression of the underwear, her ass settled into its natural, glorious shape. It was massive—two perfect, heavy mounds of soft flesh that spread slightly against the mattress. The skin was flawless, glowing in the dim lamplight like polished marble. Between the cheeks, the deep shadow of her cleft was now fully exposed, a dark valley leading down to the most forbidden parts of her body.
"Beautiful," Kai whispered, the word slipping out before he could stop it.
Ye Rou twitched, but she didn't speak. She just waited.
Kai reached for the oil bottle again. This time, he didn't pour it into his hand. He tipped the bottle and poured a generous stream of amber liquid directly onto the small of her back. It trickled down her spine, pooling in the dimples above her ass before cascading over the curve of her buttocks like a slow, golden waterfall.
"Cold..." Ye Rou gasped, shimmery goosebumps rising on her skin.
"Let me warm you up," Kai murmured.
He placed his large hands directly onto her bare ass cheeks.
Squelch.
The sound was wet, loud, and incredibly erotic.
His palms slid effortlessly over her skin. The oil made her slippery, reducing all friction. Kai groaned internally at the sensation. Her ass was incredibly soft, like warm dough filled with water. His fingers sank deep into the meat as he began to massage.
He started with broad, sweeping strokes. He started at her waist, dragging his hands down over the full curve of her glutes, cupping the heavy weight at the bottom, and lifting it slightly.
"Oh... Kai..." Ye Rou moaned, her voice muffled by the pillow. "That's... deep..."
"I need to work out the tension here," Kai said, his voice husky.
He squeezed. He grabbed handfuls of her ass, kneading the flesh aggressively. He watched the white skin turn a flushed pink under his grip. He watched the way her ass jiggled with every thrust of his hands, a mesmerizing dance of soft tissue.
He spread his fingers wide, dominating the entire landscape of her backside.
"Open your legs a little more, Mom," Kai instructed, nudging her ankles apart with his knee. "I need to reach the thigh muscles."
Ye Rou complied, spreading her legs wide on the mattress.
The view changed. The gap between her thighs opened, and Kai could see the dark, wet lips of her pussy peeking out from underneath, just barely visible past the curve of her ass.
Kai moved his hands down to her thighs. He rubbed the backs of her legs, his thumbs digging into her hamstrings. He slid his hands higher, dangerously close to her inner thighs. His knuckles grazed the sensitive skin near her groin.
Ye Rou shuddered, her hips bucking involuntarily against the bed.
"Is this okay?" Kai asked, knowing the answer.
"Mmm... yes... don't stop..." She was lost in the sensation.
Kai moved his hands back up to her ass. Now, he focused on the center.
He placed his thumbs on either side of her spine and slid them down. Down past her waist. Down into the cleft.
He pressed his thumbs deep into the crack of her ass.
Ye Rou let out a sharp gasp. "Kai!"
"Shh... the muscle connects to the tailbone," Kai lied smoothly, keeping his rhythm steady. "I have to release the pressure."
He slid his thumbs up and down the valley between her cheeks. The oil made it slick. He could feel the heat radiating from her core.
Then, he went for it.
On the downward stroke, he let his right thumb slide further than necessary. He passed the tailbone. He passed the fleshy cheeks.
His thumb glided directly over her asshole.
It was a small, puckered ring of muscle, tight and hot. He rubbed it in a circular motion, masquerading the touch as a massage technique. He pressed gently against the sphincter, feeling it twitch in reaction to his touch.
Ye Rou stiffened, her entire body going rigid. It was a shock—a violation of the highest order. But it was also wrapped in the guise of care. And the oil made it feel... good.
She didn't pull away. She didn't scold him. Instead, a low, guttural moan tore from her throat.
"Ahhh... Kai... there..."
She wasn't stopping him. She was enjoying it.
Kai smirked darkly. He continued to circle her asshole with his thumb, applying rhythmic pressure. Rub. Press. Circle. He watched the little rosebud pinken and relax slightly under his ministrations.
At the same time, his other hand moved down to her thigh again, but this time, he slid his fingers high up the inner thigh, dangerously close to her wet lips.
"You're so loose now, Mom," Kai whispered, leaning down so his breath hit the sweat-dampened hair on her neck. "Your body is finally relaxing."
He gave her asshole one firm press, almost pushing his thumb inside, before sliding his hand back up to cup her cheek, giving it a resounding smack.
Slap.
The sound of his wet hand hitting her oily ass echoed in the room. Ye Rou jolted, a wave of pleasure crashing through her.
[Ding!]
The blue screen flashed, illuminating the scene of debauchery.

Kai pulled his hands back slowly, leaving them resting on her glistening, oil-soaked ass. He looked at his handiwork. She was a mess of oil and arousal, panting on the bed, her most private places touched and teased by her own son.
"All done, Mom," Kai whispered.
