Is her sister's throat strike a surprise me?! I secretly seduce me, stealing her eyes, VR

I wonder if sisters have similar hobbies for men after all. When I went to her house to play, my sister in uniform came home... and was curious about her panties, so I couldn't hear her talk. At first I thought it was unconscious, but it was clearly provoking me...and when she disappeared, she stared at me with moist eyes and rationality exploded! Even if you know that you're cheating, you can't stop him... The excitement of not being able to tell her to be found out will drive your sexual desire! It's cowardly saying, "I'll definitely keep it a secret from my sister"!
