My SIL touched my dick the other day and I'm pretty sure I made this exact face. I had a puppy fall asleep in my lap, head resting practically on my crotch and she decided to pet the dogs head. Everyone else just patted the dog on top of the head but she decided to scratch under her chin for like 30 seconds. No one else was in the room and I honestly think she didn't even realize what she was doing, but when my wife got back I told her and she bursted out laughing and told her mom. They were going to tell my SIL had she had basically just tickled the head of my little guy with the back of her hand, but I felt so awkward and I didn't want her to die of embarrassment.
