This weekend we went to a father's day event that was dog friendly; my SIL joined us and brought her dog. I knew she'd want to see any pics I took of the dog so I made a special folder on my phone and moved some random real photos, and 2 dick pics I'd sent my wife earlier in the week. I then took pics of the dog, and moved them to that folder. Later, my wife's sister asked to see my pics so I handed her my phone and she swiped away. At a certain point, she stopped swiping, her face went red, and then looked around before zooming in with big eyes. Then she continued swiping, and gave my back my phone, saying, "You might want to move some pictures in your gallery, daddy," with a little smirk. It's been a full day since and my wife hasn't chewed me out, so I think her sister liked what she saw and kept it to herself.
