嫁の妹の甘い誘惑 ～お姉ちゃんよりも気持ちイイでしょ♪～

"So, are you sexually frustrated, big brother? Are you having sex with big sister properly?"

While I was tutoring my sister-in-law, Mimori, I was suddenly left speechless by this sudden question.

"But you're so rock hard, how much cum have you been holding in?♪ I guess I have no choice... In that case, I'll lick you right here and now☆"

Mimori curls the corners of her mouth in a mocking tone and offers a sweet, melting temptation.
