Futanari Mother And Her Torturous Daughter

Our story follows Kanoue Yuuma, an amnesiac boy with a special power, and Nikaidou Shinku, a translucent girl only visible to Yuuma who gave him that power. With it, he can heal any and all wounds.
But it comes at the cost of the memories he's made.
He lives a simple life: going to school and being scolded by his childhood friend, Kisaragi Mio, by day, and working with his master, Natsume Suzu, in the evenings.
However, whenever he falls asleep, he always sees the same dream... a white world, feathers falling, and a girl calling out for him to save her.
The student dormitory his master resides in has a special door in the basement, which connects their world to a myriad of different parallel ones. He travels from world to world, searching for one that resembles the scenery he sees in his dreams, but to no avail.

Then, one night, as he's out at night strolling around town, he spots a girl jumping from the lighthouse.
Yuuma rushes over and heals her using his power, but after coming to, the girl claims to know him and his power, and asks him much like the voice in his dreams:

"Please save me, Kanoue Yuuma."

After Junnosuke was victorious in the Pervert War, saving Seiran Island and establishing a new set of laws, he was celebrated as a hero along with his comrades. He enjoyed peaceful days with his NLNS friends while reminiscing about their past fierce battles and thought that it would continue forever.

That was until one day he heard about a certain onahole from a friend on Onatter, a social network site where gentlemanly perverts gathered. This onahole’s sensation was so amazing that he stroked faster than the speed of light, causing him to be enveloped in a bright light and brought into another world, along with the SS Big Three, who just happened to be there at that time.

This parallel world was a dream paradise where he had absolute authority as the feared SS deputy leader known as the ‘Sex Emperor’. The pervert laws were still the ones from before the war. Will he be able to safely return to his world? A new battle begins with the SS Big Three…

My name is (customizable).
That day, for a change of pace, I watched people come and go in the park.
(From here, there are subtle variations in "closet lolicon" style.)
...I wasn't looking for "that". Really, I'm only into 2D.
...I enjoyed a peek now and then, but I also respect boundaries. The law's the law.
...It's not that I'm a lolicon per se. My fantasies were pretty vanilla.
(Later)
She was extremely young, innocent in a way that even teens quickly forget. So, imagine my shock when she started masturbating in full view...!
It was like an anchor dropped inside me. It was disorienting. A girl so young shouldn't have any sort of sexuality, but she was overflowing with it.
Almost like an out-of-body experience, I took out my penis. What was I doing? I was jacking off to this little girl.
Disgraceful. No, disgraceful at first, as I struggled to grasp the situation.
This was the garden of Eden. She was Eve, doing the forbidden thing, but Eden wasn't a garden of sin until Eve ate the apple. Nothing was disgraceful.
I was probably the snake. Or the apple. But even so...

That just meant this young girl and I were fated to be together. A bond between us... two people enjoying their bodies.

Where else would this relationship go?

Shun lives with his mother, older sister and younger sister. As he grows older, he is sexually attracted to them. One day, his relatives start living at his house, a boy and his mother with a voluptuous body. Days later, he accidentally sees them having sex...

“Dear God, I now make this, the single request of my life…”
—–The near future, Nagasaki.
Into this city, with its long and checkered past
was born a rarity: a child with wings.
I don’t know when it started, but
The school overlooking the town
came to be known as hallowed ground –
and that is where we met.
