I was Harrassed by two Girls!

I'm 24M Met a girl at my work space. She is a new joiner to our organization and she is newly married. A lot of guys used to hit on her since she was pretty. But she became a friend of mine since we are in same team and moreover I'm a silent guy who doesn't flirt or bother other girls at my work space. I got broke up in my 5yrs of relationship and that's the reason for that. So initially our convo was related to work, later we became very close friends and we started to tease eachother. After 3 months, when we were on a trip with our colleagues, she confessed that she was not happy with her marriage as it's arranged without her permission. The guy is not so good looking but her parents chose him because he is rich and belongs to same caste. This guy forced her to have sx multiple times. But he can't because she wasn't interested and become very nervous during that time and her private part got tight. She even informed her parents about this but they told her it's normal and told her to adjust. She cried telling these things, i advised to get divorce,consoled her and gave her comfort. It was a 4 day trip and after her confession the same night she asked me for a hug. I felt uncomfortable to do so, but I did because she was so upset that time. A day later she again asked for hugs. This made me feel something is off, I try to avoid it but she cried and made me to hug her again. After our trip were over, she started to flirt with me. Started being touchy, cracking intimate jokes etc.. I felt uncomfortable and confessed to stop this but she haven't. When days passed, she called me one night around 1 pm and asked me to come to her place as it was emergency. Without asking anything I went there. It was her house and no one was there by that time. She want me to get inside. I refused and asked for reason for calling me this late as emergency. She said her husband was on a trip and she is alone and asked me to stay with her that night. I refused and tried to move away. But she confessed that she likes me and wanted to be intimate with me. I told her this is wrong and I'm not interested in this. But she started to threaten me that she will commit su"c"de if I leave the place. She also tried to cut her hand and i stopped her. she told me that lets do this only once I desperately need it, I've even bought protection. I had no other way and we were intimate that night. This was my biggest mistake. I just can't take it easy. Just because she is good Looking that doesn't mean I like to have sex with her. I can't stop talking to her coz in my work space I have to work with her. After almost a week, another friend of mine was texting to me. She was my close friend's fiance and a very good friend of mine too. They both were about to get married in next 2 months. Also this girl was a mutual friend of that married girl. So she texted me one night, it was regular talks but as time passed she started to flirt. I stopped texting her in insta right after that. After an hour i got a message from her in snapchat and when I opened it, I was shocked. It was her n"de image. She messaged like, I knew you had $x with that married girl and I need it too. I was shocked to the core!! I can't really tell this to my friend who was in 2 yrs of relationship with this girl but at the same time I'm not ready to get his life spoiled. Here I am Harrassed by two girls...now I'm struck. It's been 2 days since this happened I'm mentally sick now. Was not feel like going to office back again facing these two girls. And i badly wanted to convey to my friend but I fear what he is going to react. Most importantly she shared it in snapchat and all chats vanished in 24hrs. Never in my life I faced this kind of situation and I really wanna get out of this mess arround me.
