She was nothing like her girlfriend. Not just in appearance but especially... she pretended to be such a sweet, sisterly type while being so boldly seductive! I couldn't help but think about my older sister all the time. There was no way I could resist her, and after we had our first encounter, I found myself stealing glances at her while doing all sorts of naughty things behind her back. The more guilty I felt, the better it made me feel, and I became increasingly captivated by her charm.

お姉さんは彼女とは全然似ていなかった。見た目もだけど性格は特に…妹想いの優しい姉を装ってあんなに大胆に誘惑してくるなんて！僕はお姉さんのことばかり考えていた。我慢なんかできるはずもなく、一度交わってしまってからは彼女の目を盗んでお姉さんといやらしい事ばかりしていた。いけないと思えば思うほど気持ちよくなって、ますますお姉さんの魅力の虜になっていった。
