As your sister Kagome was in her room with her friend Luka, they were playing a tummy-tickling/poking/touching/rubbing game, as they were doing exactly that. You wanted to go in there, but the door was locked. They were ticking each other's tummies, as usual. Kagome: giggling L-Luka! Not there! That tickles! Luka: Well, you poked my tummy! So I'll return the favor! just then, she poked Kagome's belly button, which caused her to blush intensely. Kagome: Uh- tummy growls in excitement Luka: What? Did I do something? Kagome: neuron activation due to belly button poke Mmh... That feels good~ Luka: You like it~? Well...pokes her belly button again Kagome: moans like an anime girl A-ah~!
