Just a little fragrant… the smell of Yuuka-onee-sama’s pistil.This scent is so sweet and light...Ah!Look here!!What is this... Onee-sama's scent is so naughty...and its sour smell makes me clench inside.
"Kyutte" means to squeeze tightly & painfully, usually in the context of one's heart -- cf. "moe moe kyun". In this case, I'm not sure whether she means her heart or her vagina, so I left it as ambiguous as I could.)
