My Aunt dominates me

This is true believe it or not my aunt went nuts on me one night. This is what happened.
I was 15 years old when my uncle passed away in his 50’s. My aunt who was in her 50’s also was devastated. To make things worse she didn’t have any of her children around to be with her during that time. So being the closest to her at the time I went over with her and tried to be there for her but she was crying hard. I finally got her to stop crying but it was late so she asked me to stay the weekend since it was summer I called my parents and they said it wouldn’t be a problem if I stayed the weekend or the week it didn’t matter. She showed me the spare room and we talked in their awhile. She then gave me a hug and thanked me for spending the time with her I told her no problem. I then went to sleep feeling both sad for my aunt yet feeling like I had done a good thing staying with her. My aunt was a shorter woman maybe 5’7 not fat but heavy set, big boobs they were DD’s, thick thighs.
While I was sleeping she snuck into my room wearing a black silk nightgown. With nothing under it. She snuck in the room while I was sleeping and handcuffed my feet to the bed then handcuffed my hands to the bed. I woke up when she was handcuffing my last hand to the bed post. I startled said what are you doing? She then got on top of me by straddling me. She said this is the only way I could have you. I said what do you mean have me im your nephew! This was one night I wished I had worn more to bed then boxers and a shirt. She said that’s beside the point. I said what are u going to do. She said what do you think and began grinding on me. She then began kissing my neck. I started screaming someone help me please help! She stopped kissing me and looked at me and said o baby who do you think your screaming to? No one is home or coming home, and the next house is 5 miles away. You can keep screaming if you want im enjoying the helplessness. She leaned down and kissed me on the lips sliding in her tongue this time. She then said so our you a virgin? I said yes but please let me go I wont tell anyone I swear just let me go. She said im not letting you go and the virgin thing just got me really turned on, just think of all I can teach you, you can accept it or not I really don’t care but im going to use you, you are now your aunts personal play toy and that virgin think isn’t going to last very long if I can help it and judging by the state of things I can!
