Love story with sister-in-law

I started living with Yuri around last winter. Today, Yuri's older sister Marin had to go on an unexpected business trip. Because he couldn't find a hotel, he stayed with us for a week. Maybe because Yuri was here, she was very attentive, always on the defensive, she displayed under my eyes her gorgeous pants, her big ass. Especially after taking a shower, Marina freely walked around the house naked, so I happened to admire her beautiful model-like body. I couldn't stand it anymore. So the next morning I had to turn on the porn movie and masturbate alone in my room. While masturbating, she suddenly entered my room and witnessed everything. But she didn't leave, she came and took my phone and watched the sex movie I was playing. I'm so hot I don't care anymore. I ran forward and took over this wonderfully beautiful body.
