I Was about 10 she was 13 I think she stayed over and she asked me to sleep with her I remember her asking me to do things with her I can't remember exactly what she said or how it started I remember being late and parents had gone to bed she told me not to go to sleep later on she asked me to do things to her I remember I was uncomfortable and said something like I don't really want to she didn't say things like” if you loved me you would do it”” I will pay you don't be a boring sister” I also think she might have blackmailed me as well. I then gave in and did it. I remember her undressing herself and making me suck her nipple for a while she said to “suck till the milk comes out”. She was on her phone talking to someone, she was taking photos of me doing things to her and sending them to people. After a while she then made me lick her vagina, I think I might have said something like I have had enough because my mouth hurts. I don't remember what she said or anything I think it might have been more bribery, but I remember her saying only for five minutes and her setting a timer on her phone she removed her underwear, and I did it there were times I would stop to breathe, and she would nudge me with her leg and tell me to keep going it was hot under the blanket. I remember almost panicking because I thought I was going to pass out from the heat she wouldn't let me out till I was done the five minutes and if I did stop before the time had stopped, she would pause it. It felt like the longest 5 minutes of my life. After that she also did things to me but I'm not ready to go into that.
