HUNTC-113 | My step-sister is masturbating in adult VR and is completely unguarded! She can't tell the difference between reality and virtual reality, so she doesn't notice anything no matter what I do, so I sneakily insert it!

When I went to return the manga I borrowed to my sister-in-law, she was in the middle of masturbating with VR goggles on! What's more, she was so engrossed in playing with her crotch that she didn't even notice me standing right in front of her! Furthermore, even if I secretly touched her breasts or played with her vagina, she didn't notice at all because it was synchronized with the VR! I got carried away and inserted my hard cock into her, thinking that she hadn't noticed! It felt so good that I came inside her! Then, her VR goggles shifted due to her intense thrusts...
