I gave water to the black cow.

"It's so hot, so tell us something? A scary story would be good? ...but you know..." "Well, I do have a story where the meaning became clear later, and it left me with indescribable feelings." "Want to hear it? Actually, it's pretty famous back in my hometown... Oh, you want to hear it?" "Alright then, I'll tell you." "In the middle of a sugarcane field, there was something black." "And it was making these really agonizing cries. I don't know what I was thinking back then when I was small..." "I gave water to the black cows." "Huh? Not scary at all?" "There's an aftermath to this, but do you want to hear it?" "OK. Fair warning though, it leaves a really bad taste?" ※The title sounds lighthearted, but it's R15. And probably has a pretty bad aftertaste...
