>W-what, oniichan? you want to see m-my tummy?
>Okay... But just this once.
>tfw your little sister rubs your belly from behind every time she can
Such a nice and toned tummy too. Very smooth and it even has good color...
I know exactly what needs to be done and NO ONE would DARE STOP ME!
A pure little girl would
A. Show her tummy without feeling shame for she is a maiden and doesn't know the lewd implications of that
B. Refuse and call you a weirdo as she doesn't understand why she'd do that
That crying little girl is a slut, probably shows her tummy around town and is fully aware of how lewd that is.
Ears >> nape > tummy > breasts > thighs > hands > ankles > butts
Everyone is a leg man so that can always be left out.
