My assumption was Vedas contain only Srutis or eternal truths(an enshrined in the Mantras) and that stories and Dharma bhodhanas are a subject of Vedanta and Puranas. But the following verse(if not a later interpolation) casts doubts on that assumption. Are there any other stories of a similar nature in the rest of the Vedas?
Lopamudra's plea to her husband, Agastya "For many long years in the past, both by day and by night, And in the mornings, have I wearied myself serving you; Now decay impairs the beauty of my limbs; What then?—Let husbands approach their wives. The ancient sages who attained truth, And talked of truth with the very gods, They did beget children, but did not break their penance Therefore should the wives be approached by their husbands." (Rg Veda i, 179, 1-2)
