"Okay! You can enter!"
He would have gotten a boner from the scene before his eyes, if it was his previous life's body. But having gone through a reincarnation and his body being that of a child's, his mind was tuned to be objective of what he was seeing. This being the main reason why Asami was not that guarded against him.
As he entered the bathroom he saw Asami's clothes hanging on the rack by the side. His eyes wandered on her underwear for a bit and saw that the fashion industry in this world had yet to improve. Nevertheless, his eyes were attracted to the naked beauty that was in the bath tub, giving him a ferocious look.
Rayzen never resorted to using his Byakugan for perverted acts. Even in the house, he used to wear the headband given by Takeshi, but along with the years he shifted to the use of contacts on both his eyes, while in the house. Asami was curious about his eyes, but he shrugged her off saying his left eye was slowly turning blind and he used contacts so as to correct his vision and hide this defect.
He gulped down all useless thoughts and came closer to her. He saw her hands covering her breast and crotch. Perhaps, he stared for a bit too long. As he heard Asami's enchanting voice filled with threat:
"Eyes on the face, Ray!"
He recovered his senses and said with a 'normal' tone:
" Okay, I will do this for you if you promise that you will follow my instructions. Do you agree?"
Asami rolled her eyes as she thought:
'Really now?'
But she nodded in agreement.
Rayzen appeared to be collected as this was his first time using the Basic Impurity Cleansing Technique. If not careful, there will be serious consequences to the point of turning Asami a cripple.
He went behind her head and told her sit upright her back facing him. She did as he instructed, although her blushing face was unseen by Rayzen.
He placed his palm on a particular region of her back at the centre of her spine. Feeling his touch, she felt comfortable from his warm hand. Rayzen gave her a final warning before proceeding:
" Relax your control on chakra. Never, ever try to use or control your chakra in between, otherwise, you will die. And lastly, enjoy the experience!"
Asami felt he was not lying. She was a bit nervous, but she still trusted him.
Rayzen activated his Byakugan to use the method accurately. With the help of Byakugan, Rayzen was able to send his Jonin level chakra along various pathways through Asami's body.
As the energy from his chakra interacted with her body, she felt an ecstacy rising from deep with in her. She removed her hands from the covering position and placed it on either sides of the wooden tub that had enough space to accommodate two people.
She couldn't control her moans, beginning from a tone of pain and climbing the peak of euphoria, that rose from the heavenly massage of Rayzen's chakra. It was as if she no longer cared for Rayzen's presence. She didn't even seem to notice the impurities coming out from her pores.
Meanwhile, Rayzen was not hearing anything, as he was fully focused on using the method. He felt his chakra was draining fast.
Five minutes later, Rayzen barely managed to complete a single cycle of Basic Impurity Cleansing Technique. And without a second of gap, he fell forward unconscious. His chakra was drained to near complete exhaustion.
...
Rayzen's mind was zoning in and out. He saw the vague image of the bathtub and he felt he was naked when his brain sorted out most of the mixed signals. He also felt he was sitting on something warm and his head was also cushioned by two warm 'round pillows'. He felt disoriented and was able to not process anything properly.
He heard a sweet enchanting voice by his ears: " Are you awake, Ray?"
" I... am. What... happened? Is this... a.. dream?" asked Rayzen turning back to see he was in the laps of a naked Asami. This made him feel that he was dreaming.
Rayzen was slowly feeling his exhaustion that was coming back. But he heard her teasing voice again: "Maybe"
Memories of similar conversation and the vision that accompanied it, rose in his mind. It was of himself, or rather his previous self, cuddling with a young woman. He felt the same warmth that he was feeling now. It was a time when he felt content with his life. But...
Suddenly another thought surfaced! It was of himself lying in a bed, garbed in bandages and hospital gown, surrounded by hospital equipments. He felt the familiar feeling of warmth on him and can vaguely see the same young woman controlling her cries as she encouraged him. As he slowly lost all sensations, he asked himself:
'Is this a nightmare?!'
Rayzen hugged Asami due to the residual fear and loss of his past life, as he muttered:
"I love you! I don't want to be apart from you..."
He fell unconscious again. But with his disoriented memory at the time, he was unlikely to ever recall this 'dream'.
...
After Rayzen fell unconscious on her back, Asami was waken up from her euphoria. She blushed as she thought of the embarassing sounds she made in Rayzen's presence. But the weight on her back snapped her back to reality.
Feeling someone on her back, she saw an unconscious Rayzen and felt worried all of a sudden. She laid him down on the floor, and was about to drain the tub, when she was shocked on seeing the dirty water that had a dirty black shade to it. She came to the realisation that Rayzen was not taking advantage of her and felt bad in any thoughts she otherwise had.
She drained the tub and filled it with another round of water. She laid herself down and carried Rayzen with her and placed him in her lap. She stroked his hair, and washed his body, thinking of all the effort Rayzen had spent for her sake.
