[UNCENSORED-LEAK] LUCY-015 I was seduced by my girlfriend's sister while she was drunk... Ichika Seta

I was invited to my girlfriend's house for a family meal. Her sister was waiting for me. She treated me to a sumptuous home-cooked meal. The sister was very sexy... I wonder if it's just me... but I feel like she's been giving me strange looks for a while now...? I have a feeling that something is going to happen tonight...
