The lack of tags concern me...But the description gives me some nice vibes! I see the word 'love' and I instantly think Vanilla, after all.
Hmm, when faced with an offer like the one on page 5...Surely, nobody could refuse!
Great ending though. Well...Surely it's a good thing that she gets along with everyone in your family? Makes it a lot easier to introduce her to them as your future wife...And I'm sure they'd just nod approvingly.
And it turns out, it was all according to plan for her! She just used alcohol to set up the situation and went with it...
Natsume nee-chan used 'Drunken Marital Arts' ..... (whether or not a sequel is ever produced, we can all assume) "IT'S SUPER-EFFECTIVE!" And according to dialogue on last page, she seems to have secured the Approval from the rest of Kei's family, so ... Go For It, Kei-kun. DO NOT RESIST - IT IS YOUR DESTINY!
Man,I love that sleepy face on page 3 <3. This artist draws such cute girls. No wonder Kei-chan resolves crumbles to not get "hot and bothered" by his beloved nee-chan!
(And the tags are missing again: vanilla, oppai, skirt)
