Helping my friend do my Mom

That I don't like my Mom she is always mean to me and wishes I was never born. I am 16 and she is 44 and a little over weight. My brother has been gone from the house for a long time and it is just the two of us at home.
My friend Ron always says he would like to get in her pants and ** her big **. I tell him he is crazy, but he tells me he would do anything to do her.
Mom goes out on Friday night and has some drinks with the girls so I told Ron if he could something that would put her half out of it I would help him nail her. His Dad works at the local drug store and he said he could some stuff that would do just that.
Friday night one week ago he showed up at the house when Mom was out and had a small bottle of something that he said would do the trick. How do we give it to her he asked does she brushed her teeth before bed and I told him yes. I don't know what it was, but he soaked her brush in it for about a half hour.
She came home about 9 and she was a little drunk and said I'm going to bed. She went into the bathroom and then went in her room we gave her 30 minutes and then went in her room she was out cold. My heart was beating almost out of my chest with fear that she would wake up and kill us.
Ron pulled the sheet and blanket off her and started rubbing her ** she never moved then he said I told you it would work as he pulled up her nightgown. There was her bare ** covered with dark brown hair her ** were large and had dark ** I had never seen her ** before. Ron pulled her legs apart and she said something, but I couldn't understand her. He spit on his ** and began sliding it up and down her crack and then inside her. He took his pants off and his ** was hard he got between her legs and was trying to stick it in her. He said she needs more spit so we both spit on our hands and ribbed them on and in her. He got his ** in her and said I have dreamed of this i'm going to shoot my ** in her and then you can. I blocked out what he was saying next I just didn't want to hear it when he was finished he pulled out and told me to go, but I couldn't he said she likes it, but I still couldn't do it to Mom.
