I acted normal, as if I never felt any romantic or sexual feelings towards her when I was in her presence. But I continued my newly found hobby of stealing her used panties whenever I get an opportunity, especially those fresh wet ones that I collect just as Poornima returns home. But sometimes I notice her being suspicious about her undies missing, so I reduced my frequency.
By this time, she was preparing for her competitive exams and had appeared for them with good hopes. She was only a couple of years older than me, so I was the next one who had to face them all but, academic wise I am far backward. I have no hopes in competitive exams and so I am not even bothered about them.
One fine evening, while I was alone at home, as usual I was watching porn. I was horny all the time and I consumed a huge load of porn. There are days at which I have watched porn for more than 10 hours and that too consistently especially during holidays. I have tried to stop this addiction multiple times, but whenever I try to quit or even control it, my addiction and fetishes only multiply. Whenever I relapse, I come back to watch more and more exotic porns, sometimes even trans porn.
By this time I had a good collection of my Didi's panties. I cum on them and then I clean them up and put them back into my collection. That evening I was wearing one of her panties from my collection as I was watching porn and rubbing my tiny dick. After watching porn for a long time in my bed I went to the toilet to Jack off as it was easy to clean. My bedroom door was closed and I was alone in the house, so I didn't have to lock the bathroom doors. I sat on top of the toilet and started to get orgasms while her undies are now stuffed inside my mouth.
