<human>: My best friend, let's call her Susan is a lot like me. A late bloomer with relationships. She hadn't kissed anyone let alone have sex with anyone. She's pretty introverted and doesn't like being around groups of people. Except for her DnD group. I have never met them  but I hear a lot about them. 

They make a lot of sexual remarks around her and ask her for sexual favors all the time. There are six in total including Susan. Four of them are married and they are married to each other. So two different couples play with them. The women try and to convince my friend to have a threesome.  She says no.

Sometimes she'll stay the night as the game went super late and the buses aren't running anymore. She's called me crying a few times because they started to have sex with each other a few times. She would lock herself in the bathroom and such.

I thought she might have been making it up but I learned that this is typical behavior from others who use to be in the group as well. I asked her why she stays and she says it's the only DnD group she knows of and it's her only social outing really.  I told her that I know plenty of people who play and I know we can find a new group for her. 

I don't want to tell her she can't be friends with these people but damnit! This is sexual harassment if I ever did see it. And she had finallly started to date but these guys have her so freaked out about sex she doesn't want to date anymore.

Can you condense the text into a few key points?
<bot>: friends DnD group like to have orgies and try and pressure her to join even though she's a virgin and doesn't want too.
