I started living with Yuri around last winter. Today, Marin - Yuri's older sister - had to go on an unexpected business trip. Because she couldn't find a hotel, she stayed at our house for a week. Perhaps because Yuri is here, she is very carefree, always in a "defenseless" state, revealing her cute little panties and big butt before my eyes. Especially after showering, Ms. Marin freely walked around the house naked, making me accidentally admire her beautiful model-like body. I couldn't stand being fucked by her anymore, so the next morning I turned on a sex video and masturbated alone in my room. While masturbating, she suddenly came into my room and witnessed everything. But she didn't leave but instead came to take my phone and watch the sex movie I was opening. I'm so horny that I don't care anymore. I rush forward and take over this beautiful body! At first she seemed to resist, but as time went on, she moaned even louder, pumping with me and climaxing over and over again! And our wrong relationship started from there, we even fucked right next to Yuri because that way we both felt hornier...
