So my sister realized I was jerking off into her worn p******. Confronted me one on one and called me a pathetic jerkoff and threatened to tell our parents unless I did low level errands and chores for her and started hiding her p****** so I could not use them. After about a month went to bed one night and under the blanket was a pair and a note from her saying good job, here is your reward. God I soaked them. Became a regular perioidic reward and now I was doing her chores and errands gladly. One night late as I was enjoying the latest pair she texted me from her bedroom down the hall mid jerk and asked if I was doing it and she said tell her when I was done. Texted her when I was done and she said she wanted to watch so would bring me the next pair she gave me herself. One night a few nights later she snuck into my room in the middle of the night and woke me up and asked if I was ready. She took them off in the dark and handed them to me. It was awkward and embarassing and I could not get off and she told me to hurry before we got caught. Wanted to c** so bad I took them off my c*** and held them to my nostrils and blew. She was all omg is that what makes you c**? I was so embarassed and ashamed and she left and i kept doing her chores but was worried she would never give them to me again. Weeks went by before she snuck in again and woke me up and took off her p****** and this time held them to my face herself. Hard instantly shot off in seconds. So now she comes to my room a couple of times a week and holds them to my face or once even shoved them in my mouth to make me c** fast.
