Talked to jerking off at work

Recently I was chatting up with one of my ex girlfriend who still happens to be a friend. We were talking about sex of course, and she was talking about her man while recently kicked to the curve man would never do anything crazy with her despite her willingness to do almost anything for him. Somehow as we were talking more about sex she started telling me that she was playing with herself, that somehow my voice was turning her on. That we were texting because I was at work, and it happened to be the weekend where that many people are around. So when she started talking about how she was feeling horny and needed to get off. She talked to me about how she had this how I used to have sex with her well in her words "I miss the way you fucked me". Then she started to use her ability to talk sexually talking about how it would be hot if we went to the bathroom together and started to play with each other. I knew I had some time to kill, so at least went to the bathroom with the idea of just playing around but it turned into much bigger that I thought, because then she started sending me pictures with dildos and other stuff. Including adding and voice messages about what she would be doing. My man who took over and I started to jerk off at work completing it within a couple minutes making sure that I hit the toilet perfectly. Don't you ask me to take a picture of myself as I just finished which case I did share with her and she admitted the she exploded all over the floor of her bathroom. Before I can actually finish a text message with a bag on the door for the person outside waiting to come into the bathroom. I cleaned up and rushed off back to work. She sent me a text thank you, she needed to let go.
