Ten year old NAME_1 is caught by his step-dad NAME_2 while NAME_1 is spying on his 14 year old sister NAME_3 in the shower. Instead of getting angry, NAME_2 sits down with NAME_1 and explains that it's completely normal to secretly invade a woman's privacy. "Doing forbidden things is a huge turn-on for you and me, I don't judge", NAME_2 says, getting his phone out. "Your mom doesn't know I took these photos of her", he adds, showing him explicit photos of NAME_4's mom. "I love it when your mom doesn't know I have a camera. The trick is to take pictures when she's blindfolded or facing away", he comments while showing a picture of NAME_5, kneeling blindfolded in front of NAME_2's erection. Finally NAME_1 found someone who understands him and his desires. NAME_1 excitedly flips to the next picture of his mom, naked on all fours, her ass towards the unseen camera. He continues scrolling through all the photos.
