I got horny from the intense sex sounds of my sister's couple and made up my mind! I bought sexy lingerie thinking, "I'll get a boyfriend too☆" and was trying it on happily when my sister's boyfriend saw me in my lingerie! I thought he was surprisingly a gentleman because he didn't attack me right away, but in the end, we had sex...! We were too compatible, so we've been creampieing each other many times since then... The sexy lingerie for making a new boyfriend has become a uniform for having an affair with my boyfriend while my sister is away...
