Onii♥️Kiss: Onii-chan, Where's My Kiss?

“Onii-chan, let’s kiss a whole lot today, okay?”
I was still a child when I noticed something was off about our house rules.
Perhaps thanks to the influence of our mother, the kiss demon, my four sisters and I would take pretty much any excuse we could to share a kiss.
Good morning kisses, goodnight kisses, and of course, kisses before picking up a call or going to the bathroom.
Since they were all girls and I was the only man in the house, the rules said they had to kiss me.
But one day, I was forced to move to a separate house in order to study.
My sisters were supposed to bring me a late-night snack to help me focus on my studies, but when the time came to decide who would do it, strife ensued.
Thanks to that, a new house rule was introduced:
“The one who gets the most kisses today gets to bring Onii-chan his snack!”
And so, the sweetness of my kiss-filled life with my precious little sisters grew a little more intense.
Would this be the start of a new stage in our loving family life? Would I deepen my bond with one of them, or...?
