My sister (18f) has always been a bully to me (20m). She is athletic, popular, smart, and insanely attractive, and she knows it. I, on the other hand, am not any of those things. I never made any friends in school, I'm chronically scrawny, barely graduated high school, work at a grocery store for minimum wage, and live with my mom with no real plan or motivation to move out. Its always felt like something went wrong with me, and though my mom will never say it, I know she's disappointed. My sister however has no problem telling me how much of a fuck up I am. She still lives at home as well, but is going to be moving out for college next year. She loves to burst in my room and mock whatever anime I'm watching, or game I am playing, and she has caught me jerking off multiple times, and every time she calls me a pathetic loser and leaves. Obviously I am posting here so there is a part of me that likes all the degradation I get from her, so I dont fight back really.
Recently I have been taking creepshots of her ass cause its simply astounding and she wears these tiny little shorts around the house that leave most of it hanging out. I also took a pair of her panties and shoes I didn't think she wore that often and have been masturbating using her shoes to bust my balls while I wear the panties. I know its fucked up and im under no illusion that im a normal guy. Part of me feels bad, but also Ive come to accept that im just a little fucked up.
I believe that she is responsible for my ballbusting fetish cause its always been a habit of hers when shes especially pissed off. Thinks Im looking at her friends when they are over? Kicked in the balls. Has to drive me home from the hospital? Helped me to bed and sack tapped me. I took too long in the bathroom? Shes there waiting to knee me in the crotch. And every time I get so hard, and so horny I have to go to my room and jerk off.
Now with all that context, flashback to a week or so ago. Im in my room jerking off with her panties on my face and she barges in. I cover up as fast as possible, throw her panties away and at first she calls me disgusting and turns away but then she realizes its her panties on the floor. "What the FUCK do you think you're doing?" She picked them up and looked at me with a rage in her eyes i had never seen before. She walked over to my bed and threw my covers off of me and slammed her hand down on my balls, squeezing them so hard I thought I might puke. She held the panties up and said "I knew you were a fucking creep but what the fuck is this?" She squeezed tighter, it felt like she was going to rip them off. I tried to plead for mercy but I couldnt get any words out, and i felt it, if she kept squeezing i was going to cum. "Im gonna tell mom and youre gonna get kicked out of the house you pathetic fuck" and with that I came. "WHAT THE FUCK?!?!" She took her hand away and walked out.
Now its been a week, I talked with my mom and shes disappointed but said she wouldn't kick me out. My sister hasn't talked to me since, but whenever she sees me around the house she glares daggers at me. I cant stop thinking about it and how I could get her to keep ballbusting me. And yeah, thats my story. My balls took days to recover. I still use her shoes since she didn't find them. She hasn't burst into my room since. When i talked to my mom she said I had to get signed up for therapy and maybe we'd have a family meeting about it, but also my sister isnt interested if it isnt a talk about me moving out.
If anyone has any ideas on how to get her to keep ballbusting me please let me know.
