Honestly, I never thought that my nephews stay would make him go from simply my nephew to my ABDL nephew. I discovered a few pictures of John wearing some very childish diapers, with cartoon characters all over them, on his laptop, along with some kinky incest stories that he had open. I choose to let him know that I knew about his diapers and breastfeeding fetish but also that I was really turned on from the idea of taking care of him like in those stories, I couldn’t be his abdl mom, but I could be his abdl auntie! When he came to my house after school, I told him that we needed to go to the mall for a few things. He asked if he could stay because he really wanted to play a new video game that he got, but I refused and off we went.  After a few stores I noticed he was walking funny, as well as holding his bags in front of his pants as we walked around.

Once that was done, I told him to lay down on the bed, legs in the air, so I could diaper him.  I was NOT going to have to do pissy laundry all week long! I sat him on his bed and opened his laptop to show him what I had seen, of course he was embarrassed again. He even looked a little scared when I told him I wanted to watch him touch himself like he does when he’s alone. But there was something else I saw in his, something that was getting stronger – arousal. Sitting on the edge of the bed, I watched as he rubbed his little pp through his diaper.  I commented that I could barely see any bulge, his dick must be as small as it was when he was a baby.  He blushed and twitched some more, and his hips jerked hard with how much he loved that little bit of […]
