for now inkeeps daughter and that grandmother girl can not be impregnated at least not visible. Butfrom what i learned in this Thread here inkeepers daughter may be pregnant already in you save when a new reales has pregnant scenes...
As far no girl gets pregnant, unless she ask you to cum inside or force you to (Shakala in almost kill you scene).
If you decide to cum inside inkeeps daughter or Gabriel daughter, they won't have sex with MC for sometime.
At the end of the temple quest, Gabriel spreads the news to the main town and the MC gets famous.
That is the reason that Gabriels daughter says "I missed you MC" after this quest.
MC at that moment has a lot of coins, by killing goblins trying to increase MC level to fight all the orchs of the second temple quest.
So at the end of this version MC is reach and famous. Rest is version update.
To the question, why the shop lady has no scenes, I think that sex scenes are with any female that the peasant has a quest.
That's the sense!
If there is ever a quest for this woman, they might be scenes with her also.
