I taught her how to get off on a cock

My niece came over last night and she was just talking about how she wanted to have sex and cum her first time. I asked her if she masterbate and she said she does it all the time but she doesn't have any cum loads. That's when she said noone had touched down below on her. She came over wearing a baggy long t shirt and no panties. So I went to the back bathroom and she came 3 10 minutes later. I was nude and she said that she wanted to touch my cock so I told her I would off her shirt and she did. She had some hair on the top of her pussy and she said that she shaved the rest off.i asked her if she wanted it all gone and she said yes. So I grabbed the razor and she was bald below she rubbed it and she said that she loves it smooth. I turned on the shower and when it warmed up I wash her butt and pussy and I put my 2 fingers in her holes and she was moaning and she said that she likes it in her holes. Then she stroke my cock and she sucked on my dick and nuts and she fingered my asshole and she said that she had wanted to do that for a long time. Then she had 3 fingers in my butt then 4 and then her whole hand and I was moaning and she was inside almost up to her elbow. I put some lube on her arm and she had it up past her elbow and almost to her arm pit. I'm getting super hard and she is moving her arm and I am super excited.. she fucked me hard with her full arm then she pulled it out.she had turned 19 last week and she said that her boyfriend would show her how to masterbate and um as I did him. I shoved dick in her mouth and then her pussy and yes her asshole.she came on every hole. I grabbed a dildo and I fucked her hard with it.she swallowed all 8 inches of it in her mouth and pussy and asshole when she got it in her pussy she was screaming loud and she came several times both in her mouth and pussy and she was squirting out of her pussy. Then she said that she wanted to be butt fucked and when I did she put her hand in her pussy and she cumming hard.then I put my cock in her mouth and she made IT squirt her mouth full and then her pussy was cumming on my dick.
