"Your sister must be sick," Haruko said matter-of-factly while Seiji was eating.
he said it to no one in particular, but there was no one else in the kitchen except the two of them.
Seiji looked over.
"Sick?"
"Probably." The stepmom kept washing the dishes. "She only came out to get some water. I asked her why she didn't come for breakfast, and she told me she wasn't feeling well."
That's true. She wasn't here at breakfast.
Seiji cursed himself. The entire day had passed, and he had just noticed.
He had an unpleasant feeling.
What if she's overthinking it again? Is she going to pull back again?
He thought it would be crazy after how happy she was last night.
But then again, after what happened with Ayame at school, he didn't know what other surprises to expect.
Seiji went upstairs.
He didn't go to Yumi's room right away. He waited until his dad got home, had dinner, and retreated to the bedroom with Haruko.
"Come in," Yumi replied to Seiji's quiet knock.
The door yielded slowly.
Yumi was sitting in the center of the bed, her back against the headboard.
She looks like she's been waiting.
She wore a pale pink nightshirt, the fabric thin and trimmed with a small line of lace. It was different from her usual oversized tees. It was for him.
She's been waiting for me!
Seiji felt he was getting hard already.
The baby's breathing in the crib was steady and rhythmic.
Yumi was looking at Seiji as he approached.
She didn't smile. Her eyes were dark, tracking his movement with a quiet, burning intensity.
"You came," she said.
Seiji nodded.
"I heard you didn't come out. Are you alright?"
She kept looking straight into his eyes.
"I didn't feel like it," she replied. "I felt too good to ruin the feeling."
Seiji sat on the edge of the mattress. The springs squeaked softly.
"Instead, I was waiting for you," she added. "Could you feel it?"
How could I possibly feel it?
"Yes," Seiji lied.
"I knew it," she exhaled, forcing a smile now.
Seiji touched her arm. Her skin was fever-hot.
"So you're okay?"
Yumi gave a tiny nod. "I'm great. Even better now…"
Her lips were so close, and stayed slightly parted. She was waiting…
Seiji leaned in and kissed her.
She's breathing so fast.
Yumi lay back against the pillows, her gaze fixed on him. With a slow, deliberate movement, she drew her knees up. She let them fall outward.
There was nothing under the nightshirt.
"Seiji," she breathed.
She wants it. She wants me again! Oh god, I'm so lucky!
He moved between her legs.
Her thighs instinctively jerked as they brushed against his hips. Not fear. Not nerves.
Only desire.
Seiji leaned over and entered her with a slow, heavy slide. Yumi gasped, her head falling back, the line of her throat pale and exposed.
She looks beautiful, when she's eager and defenceless like this.
Seiji kissed her throat… her chin… her chest…
Yumi was wetter tonight.
More than ready.
Her body tightened around him, welcoming him.
He gripped her hips, and started to move—driving deeper and deeper.
Slow at first.
Yumi's eyes stayed open. She watched him plough into her.
A soft moan escaped her on every thrust. She wasn't hiding her voice anymore.
She wasn't holding back the tide.
"You… you are hitting so deep…" she whispered feverishly. "All the way… into my chest… my heart… ah…"
Her hands slid down to his lower back.
Her fingers pushed hard, urging him deeper.
"More," she whispered.
The heat built. The shadows on the wall danced as Seiji moved faster.
He watched Yumi's face—the way her teeth caught her lower lip until it was bruised and red.
He leaned even closer.
"Yumi…"
"Don't stop," she panted.
She was close.
He could feel it in the tension around him. A coiled spring ready to snap.
"Seiji… oh god—"
Her legs wrapped around his waist, locking him into her.
She shuddered in a series of violent tremors. They started at her core and radiated outward. She didn't moan; this time, she cried out, a sharp, freeing sound she muffled against his neck.
"Seiji-i-i!"
Then her head dropped back onto the pillow and her eyes rolled back. She went rigid, then limp.
Seiji lost control. The power of the amulet was nothing compared to this—the raw, physical release. Or maybe it was the amulet driving him into another dimension.
"Cumming!"
Yumi squealed, shaking and shuddering again… on and on and on…
Later, Seiji rolled to the side. He pulled the duvet over them both.
She pushed her back against his chest, her small frame fitting perfectly against him.
A perfect spoon.
I would've never thought that my sister would be my first lover. And what kind of lover!
Yumi was still shivering slightly.
He held her tight, until her breathing slowed.
Yumi turned in his arms. Her face was only inches away.
She looked exhausted, but her eyes were clear. Her upper lip touched his.
"I've never felt like this," she whispered. "Ever."
Seiji gave her a smile.
She looked away, then back, her voice dropping even more.
"Seiji… I love you," her hands wrapped around him neck. "I love you like I've never loved anyone before."
