酔うと記憶が飛ぶ姉ちゃん… ほんとに酔ってたのかな? My sister has trouble remembering things when she's drunk. Was she really drunk? (Lines in the illustration) Forget everything that happened yesterday! I was drunk, that wasn't me! You tell anyone about this, and I'll kill you. And, uh... you were wearing a condom, right? Sis, you're drunk. I'm not drunk. Hurry up and put your dick in me.
