Time Enough for Love

This is what I'm dealing with here:

The long-lived galactic playboy and entrepreneur (who is generally good at everything without having to work too hard) Lazarus Long (a. k. a. Woodrow Wilson and a ton of other names) is having a conversation with his adopted daughter Dora, who he rescued from a fire that killed her parents when she was a young child:

"Woman, you talk too much." She did not answer this; he went on: "I don't give a hoot about a wedding ceremony—certainly not one in Top Dollar."

She hesitated, then said, "May I say that I do not understand?"

"Eh? Yes, surely. Dora, I won't settle for one child. You're going to have half a dozen children by me, or more. Probably more. Maybe a dozen. Any objection?"

"Yes, Woodrow—I mean No, I do not object. Yes, I will have a dozen children by you. Or more."

"Having a dozen kids takes time, Dora. How often should I show up? Every two years, maybe?"

"Whatever you say, Woodrow. Whenever you come back—each time you come back—I'll have a child by you. But I do ask that we start the first one at once."

"You crazy little idiot. I believe you would do it that way."

"Not 'would'—shall. If you will."

"Well, we're not going to do it that way." He reached out and took her hand. "Dora, will you go where I go, do what I do, live where I live?"

She looked startled but answered steadily. "Yes, Woodrow. If this is truly what you want."

"Don't put any conditions on it. Will you, or won't you?"

"I will."

If it comes to a showdown, will you do what I tell you to? Not give me any more stubborn arguments?"

"Yes, Woodrow."

"Will you bear my children and be my wife till death do us part?"

"I will."

"I take thee, Dora, to be my wife, to love and protect and cherish—and never to leave you... so long as we both shall live. Don't sniffle! Lean over here and kiss me instead. We're married."

"I was not either sniffling! Are we really married?"

"We are. Oh, you can have any wedding ceremony you want. Later. Now shut up and kiss me."

She obeyed.

Some long moments later he said, "Hey, don't fall out of your saddle! Steady, Betty! Steady, Beulah! 'Durable Dora, who taught you to kiss that way?"

"You haven't called me that since I started to grow up. Years."

"Haven't kissed you since you started to grow up, either. For good reason. You didn't answer my question."

That's where I stopped. This is after the protagonist sails around space with a brother and sister he purchased from a slave trader. He forces them to be nudists so he doesn't have to do laundry, although he rewards the sister with clothing when she behaves by not nagging her brother. This arrangement eventually results in the siblings having a child together, but it's okay because they came from haploid gametes. Now their children on the other hand...

This is also not long after the talking mule.

There are 300 pages left. I just can't do it.
