I started living with Yuri around last winter. Today, Yuri's sister Marin had to go on a sudden business trip. Unable to find a hotel, she stayed at our house for a week. Perhaps because Yuri was here, she was very carefree, always in a "no defense" state, revealing her cute little panties and her big butt in front of me. Especially after taking a bath, Marin comfortably walked around the house naked, allowing me to inadvertently admire her model-like figure. Unable to resist her arousing me, the next morning I had to watch a porn movie and masturbate alone in the room.SSIS-343 Crave to fuck sister-in-law While masturbating, Marin suddenly entered my room and witnessed everything. But she didn't leave, instead she took my phone and watched the porn movie I was watching. Feeling extremely aroused, I no longer cared. I rushed over and claimed this beautiful naked body! At first, she resisted, but the more it went on, the louder she moaned, matching my pace and reaching climax time after time! And our twisted relationship started from there, even having sex right next to Yuri because that way we both felt even more aroused...
