Anon, why do you become flustered and sexually aroused when I show you my bare, naked soles?
I'm your little sister, is it really okay for you to have such sexual thoughts about your sister's naked feet?
OP you should just do it. I know what you're trying to ask. Incest isn't incest until it involves sexual contact. Feel free to lick your sister's feet (if she isnt a minor) but once you put your dick on them, you'll be considered over the line.

Licks are sexual though, especially feet licks.

if you say so. Normalfags dont consider it to be the case
