My favorite new thing to do is babysit my friend’s adult diaper lover husband. She drops him off at my house every day with his bag full of diapers and toys. I have a crib set up for him in my spare bedroom. After a few hours of playing with his toys, I put him down for a nap. I know he likes to be a naughty little brat so I have restraints at his wrists and ankles to keep him in the crib. I check on him every hour and reach in to see if his diaper is wet. Last time, I pretended not to notice that he had a hard little cock in his diaper. I changed him and left the room. When I came back later to check on him, he had gotten out of the restraints and had a hand in his diaper, playing with his hard cock. His mommy told me to punish him if I caught him playing with his wee-wee. I took him out of his crib and bent him over my lap. I pulled his diaper down just a little and spanked his naughty little ass! As I was spanking him, I could feel his hard cock through the front of his diaper pressed against my leg. I felt it suddenly get warm as he relaxed a little. I realized that he made a sticky mess in his diaper from being excited about me spanking him. What a bad little one! I told him he had to go to bed in his sticky diaper as punishment for being such a naughty little brat.
