Part 3: This gallery

Boyfriend is more or less left without lasting damage, with his Netorase hobby not utterly destroying his relationship with Kaede. After asking Kaito to help him conceive a child with Kaede she does want her boyfriend / fiance to have a 1-on-1 with her still, wishing for her baby's father to be left to fate.

In the end, as married couple, Kaede's belly has grown big 6 months later, the boyfriend (now husband) contemplates about Kaede becoming truly hooked with Kaito as her partner so they are still sex friends, Kaede has truly become what her husband wanted. Kaede in turn reminds her husband about the paternity test results he didn't want to see at the last minute, telling her not to show him and rip it to shreds, she says the little girl in her belly is his... but he doesn't seem to believe it, she insists it is, Kaede was sure the moment she heard him say he will love her and the child no matter what back during their maternity clinic visits, she will stay with him forever.

The synopsis above is...
Intriguing to say the least, perhaps AI generated ?

Basically what happens:
- After the past 2 part (yes, this is the part 3), husband (will be reffered to as MC) continues netorase, even until they got married.
- On the wedding night the wife (Kaede), start a "competition" of who could impregnate her first between MC and 2 other men.
- 1st Men is the guy from part 1 (Yuuji)
- 2nd men is Daisuke, where basically kaede fawns over so much, saying he's her fated one, and kept talking about wanting to be impregnated by him (and other hot stuff).
- Ending basically say that MC and Kaede stays together, but Kaede can no longer be satisfied without Netorase with Daisuke
- Kaede was like: "it's your child"
- MC can't truly believe it, but still promise to raise the kid and love her.
- MC also tell Kaede that he did not want to see the paternity result, so Kaede threw it away.

TL;DR
Hardcore cuckold impregnation ends with likely another man's child.
Wife happy, bull happy, cuck happy.
