Another title for this chapter could be “breasts” because that’s what it’s about.

The woman says something kind of cringe for us but erotic for her.  She says that she wishes he would be like her brother that openly nurses on her mother’s breast, so that he could do the same and it would not be wrong.  It’s just the imagery that’s kind of cringe but Ok.

Then back to breasts.  The friends say there is a younger sister whose breasts are not mature.  Is this the woman or is it literally a younger sister?  Or is it a flashback to when she was younger and her brothers had to plan for this day?

Probably it’s the latter.  Because now it seems her breasts are mature, “like towers” (v. 10).

And then it seems like there is a wedding, “with friends in attendance” (v. 13) celebrating this love.
