Stepdaughters dirty knickers

I've been stealing my stepdaughters dirty knickers since she was 13. She came to stay with me for a while and I noticed she didn't shower or change her clothes very often. I had a talk with her that her mum obviously didn't. I told her she's not a little girl anymore and she needs to shower everyday and change her undies, or she'll smell. I got her 20 pairs of Bonds boylegs and told her to put her dirty clothes in the machine and I'll wash and dry them for her. I never intended to be a deviant, but I saw 2 pairs in the machine and took them out. One pair was orange and had a dried yellow crust on them the other black had menstrual blood on them. I sniffed them and wanked over them and kept them a snap lock bag. One day I just couldn't resist and chewed the yellow crust off them. I also smelt her cute little girl bra and her sweat and body spray. Next time when she was 17, I command's around her bedroom floor and got a lacy purple French panties. She was now sexually active and wore sexy undies. I ended up stealing 5 pairs, mostly thongs and sucked them clean. She had a bin in her room for her worn knickers and there were heaps. I didn't want her noticing any going missing, so picked out a blue and green thong and took it down the road to a public toilet. The gusset was obviously full of male c**, so I didn't lick them but wanked over them and took them back. I've done this with another friends 18yo again comandoing around her floor and taking 5 pairs again. My problem is, I like this better than s**, which I get plenty of. Atm I have no stolen undies and I don't know how to get more. I'm sure I will though. I hope this is not too abnormal but feel it might be. Oh well, happy sniffing and licking fellow dirty knicker lovers. Gussetlover.
