<human>: While I was jacking off, I was thinking about a friend of mine. She's pretty good looking with a nice body. I also know a friend who likes her, and is a pretty hot tempered person, and very protective as well. So I was imagining myself going down on her, when I suddenly thought, what if he comes in and gets all angry? So in my fantasy, I brought out a gun, and whilst in the act of fucking friend number 1, I shot friend number 2 in the head and laughed, and when I was done with friend number 1, I shot her too.

Can you summarize the given text in a few sentences?
<bot>: had a fantasy with a friend in it, another friend came in to protect her from me, i shot him and once i was done fucking my first friend, shot her too.
