"Please, Seiji."
The words sounded like a prayer.
Yumi squeezed Seiji's hand desperately while he kept watching that single bead of milk, a white pearl on the pink of her nipple.
What exactly is she asking for?
He looked up from her breast to her eyes. They weren't just pleading. They were promising. Promising him all of her.
Oh, Yumi… Are you sure?
The amulet weighed Seiji down, and he instinctively leaned forward.
The second his lips touched Yumi's breast, she gasped loudly.
Another line had been crossed. The most forbidden of them all. Seiji knew it, but didn't really think about it, his brain filled with the amulet's hum.
The flavor of the bead was warm and sweet.
Yumi shuddered, a violent, full-body tremor. Her hand grabbed the back of Seiji's head, her fingers tangling in his hair, holding him to her with surprising strength.
"Seiji..."
She needed more.
I can't believe I'm doing it!
But he kept going.
When Seiji felt Yumi squirm even more, he pulled back just enough to see her face. She stared into space as if she was in trance.
"I've... I've never..." she stammered. "I didn't know... it could feel like that… Heavenly…"
The words entered Seiji's brain.
Never!
Not with her husband. Not with anyone.
He was the first.
"Don't stop," she gasped, her gaze snapping back to Seiji. "Please... don't stop. Please."
That was all he needed to hear.
Seiji lowered his head again, but this time he took her nipple deeper into his mouth, his lips creating a strong, consistent suction.
Yumi cried out, her back arching, pressing herself against him. The sounds she made were no longer gentle; they were the noises of a dam breaking.
This was a woman being reborn.
As amulet flooded his chest with heat, Seiji felt like he wasn't just drinking his sister's milk; he was drinking her soul.
He was the first and only man to give Yumi the type of pleasure she never knew.
Her movements became frantic. "Oh god, Seiji... Oh god..."
Seiji didn't let up.
He pushed her higher and higher until she finally shattered.
Her entire body went rigid, a silent scream tearing from her throat as the orgasm ripped through her.
It was so powerful that she convulsed in waves for what felt like a long time, until she collapsed, her hands squeezing Seiji's neck, completely undone.
Seiji watched Yumi's face.
Her eyes were closed, a single tear slowly tracing a path down her cheek.
A tear? Why? I thought she'd be happy.
Then, Yumi's eyes fluttered open. They were clear. Calm. And satisfied.
Seiji could tell she knew a permanent change had taken place.
Not only had her brother given her this pleasure, but it was the kind she never knew existed. A feeling only Seiji could provide.
Seiji touched the amulet, proudly.
He had just redesigned the woman inside his sister. Unlocked Yumi's new dimension.
Her soul was now his.
And he was never giving it back.
