there's going to be some leaps in storytelling, it's an eroge after all. but what you're mentioning is something already considered, and written into upcoming content.
maybe, make it happen if the BF is into it, and not if he is against it, it can still sort off happen as well but it would be "leaked" later in the story,
with the 1st picture there can be a stop "leaked later" route or continue "I want to see"
