That's exactly what makes it wholesome; it shows that the cuck is willing to commit to the girl and to their shared kink for the rest of their lives. It's the "and they lived happily ever after" of netorase.
It's definitely hardcore, but I like it. Your waifu loves you so much that she is willing to bear another man's baby just to satisfy your fetish, and you will have a hard-on for nine months straight every time she catches you looking at her pregnant belly and she smiles and reminds you that it's not yours.
It's important that the bull get treated as nothing more than a sperm donor, though; otherwise it turns into NTR.
And I do wish more stories would show things out a little further in the future. Even most NTS impregnation stories end with the creampie, an egg being attacked by sperm, a positive pregnancy test, or at best a pregnant belly. I'd like something that showed the birth and raising many years later.
