Sex wasn't something strange to Ren. He carried fragmented memories of being with a woman in his previous life. The details weren't clear, but those memories unsettled him—because that woman filled him with both fear and anger.

Ever since arriving in this world and awakening to his powers, along with fragments of his past, Ren had realised one thing about the women here: they were beasts when it came to sex.

Kyouka—normally the cool, calm, and collected elder sister—now looked like a harlot in heat, with half of Ren's hand buried inside her.

He felt his four fingers spreading her pussy walls open, ainding against her folds, until his fingers touched her cervix, unable to reach any further. She let out a low guttural voice, the type that only a woman could produce.

"Ooooohhhhh!"

His fingers were now inside her until beyond their edges and he was able to appreciate the feeling of her vagina through his fingers. They had many more ways to move compared to a penis and their sense of touch was also much more detailed.

He was able to feel her creases and folds in detail and pressing a finger allowed him to discern their texture more specifically. His fingers were completely surrounded by her flesh and he could feel it pulsating regularly, as if in excitement, while continuously releasing a generous amount of fluids, which helped lubricate any movement he took inside her.

His adopted sister panted for a few seconds before continuing to instruct him, thinking he needed help.

"That was perfect, Ren. You almost made me cum with just this. Now, rotate your fingers several times and when you feel ready, start to move it back and forth, without taking themcompletely out."

He followed her words and started to rotate his fingers. The margin of movement was poor at the beginning, his fingers rubbing strongly against her walls, making her moan delightedly. Little by little, he could feel that it was easier to move, as if her pussy was starting to accept his presence.

Her folds still surrounded him but the pressure was less intense than at the start. He guessed that was the reason why she asked him to do this. He thought that the time was right and started to pump his fingers in and out of her, the grinding of his fingers and her pussy making an extremely lewd sploshing sound.

Feeling the intense stimulation of his fingers moving back and forth, his sister was in ecstasy and started to be vocal.

"Ooohhh! That's good! A man's hand is completely different! Ooohhh! Stronger! Don't worry about anything, just do it stronger!"

He obeyed her and began to violently finger her pussy, her juices flying in all directions and her pelvis and lower belly visibly deforming through the constant motions of his fingers inside her.

"Oooohhhh! That's it! My clit! Rub my clit with your fingers!"

He put the fingers of his left hand on her clitoris and started to vibrate them on it at full speed, constantly bumping into her urethra and stimulating her even further.

"Ooooohhhhh! Yes! It's perfect! I am close! Look at me, Ren! This is how a woman orgasms! It's coming! A big one! Look at me! Look at me...!"

Finally, she howled in an incredible voice, her low squeal resonating in the bathroom and making the walls of the room tremble.

"Oooooooooooooooooooohhhhhhhhhhhhhhhhhhhh!"

She squirted a long jet of fluids, her body shaking greatly, spasming with violent jerks, while her eyes rolled in her sockets. Her tongue was out, saliva dripping on her breasts. Her clitoris was shivering uncontrollably while her pussy contracted powerfully around his fingers as if to never let it go.

Her squirt jet pressure was amazing, hitting and drenching his face with full strength, while also feeling endless. He didn't need to do anything and simply opened his mouth for everything to enter by itself, her squirt not stopping for a good ten seconds.

He enjoyed her womanly and salty taste, gulping it all, fascinated by the view of her climax. As she said, it was a sight to behold and Ren felt happy to have witnessed the deep orgasm of a such an beautiful woman at least once in his life. It felt even better knowing that it was his adopted who loves him and he had been able to pleasure her so much.

Ren looked down at his own dick and noticed he was also dripping juices into the bathtub. This struck him as strange about his new body compared to the memories of his previous life—he was getting much wetter than he ever remembered back then.

"Ugh~ I want to cum," Ren muttered to himself. He expected Kyouka to be completely exhausted after that huge orgasm she had—a welcome sight for him—but unlike what he imagined, within seconds she suddenly regained her energy. Now, however, she was staring at Ren like he was prey waiting to be devoured.

"Ren! Come here," Kyouka said in a sultry voice, like the very incarnation of lust itself. Curious about what she was up to, Ren stood up from the bathtub, his erection pointing straight at her, and approached—only for something unexpected to happen.

Perched on the rim of the bathtub, which was nearly flush against the wall, Kyouka suddenly lifted Ren out of the water without any effort. The ease of it freaked him out—how the hell could she do that? It was a stark reminder of the difference in their strength and stamina, a dark truth of this world. She held him firmly by his asscheeks, raising him so high that his cock was now directly at the level of her face.

"Ren, hold onto the wall if you feel like you're about to fall." It was a dangerous position—if Kyouka made even a single mistake, Ren could slip and suffer a head injury.

He didn't like the idea of Kyouka taking control like this, but honestly, he couldn't even move. Still, he didn't want to seem weak by refusing her. Fortunately, before things could go any further, both Kyouka and Ren suddenly heard a female voice coming from outside, snapping them back to their senses.

The voice belonged to none other than Misa, who had just come home from work.

Kyouka froze. Her lustful gaze flickered, the fire in her eyes dimming as reality slammed back into her. The sound of Misa's voice was like a bucket of cold water poured straight over her head.

Ren's heart skipped a beat. His body was still trembling from the position Kyouka had forced him into, but he managed to twist his neck toward the door, his voice cracking as he shouted,

"I—I'm inside the bath, mother!"

A pause followed. Then, Misa's muffled voice came again, laced with confusion.

"Ren? You're still bathing? …Have you seen Kyouka? I need to discuss something with her."

Ren swallowed hard. He didn't dare look down at Kyouka, whose face was still level with his cock. Slowly, she lowered him back into the bathtub, her hands lingering for a moment before slipping away.

"…Don't say I am here," Kyouka whispered, her voice unsteady, her expression betraying guilt she couldn't quite hide. She turned her face away, cheeks flushed not with lust this time, but with shame. "I'll leave."

Ren sank into the warm water, his chest heaving as he tried to calm himself. He didn't miss the way Kyouka avoided his eyes, the usual confidence she carried nowhere to be seen.

Meanwhile, outside the door, Misa's footsteps faded away giving Ren some comfort that he wasn't caught trying to have sex with his adopted sister.
