LUCY-013 - I was cuckolded by my girlfriend's older sister while she was drunk. Sayuri Hayama

I was invited to the home of my girlfriend and we had dinner together as a family. Her older sister was waiting for her. He served me a sumptuous home-cooked meal. That older sister is a very sexy person... Is it just my imagination...I feel like he's been staring at me for some time now...? I have a feeling something is going to happen tonight...
