Friends with cuddle benefits

I had a strange relationship with a girl named Ashley during the second semester of my freshman year of college. We became friends from bumping into each other enough in the common areas. She commuted to school and I lived on campus. There was certainly a physical attraction there for both of us. Just 1 problem with this: She was in a long distance relationship at the time. I am not sure exactly how it started happening, but she would eventually start coming over to my dorm room and requesting that we cuddle. Trust me; I know this sounds bad, but i obliged. I very much knew she was in a relationship, but I had just ended my relationship with my high school sweetheart around that time so I was in the market for some cuddling myself. Ashley would just come over when she was done her classes and jump into my bed, beckoning me to join her. I'll never forget that she liked being the big spoon. Both of us understood the situation and none of us took it any further then simple cuddling. I think she just needed to hold and be held because she lacked that aspect of the relationship she was in. She still very much loved her boyfriend, but she just needed that immediate comfort that was impossible to get from him at the moment. This story would be okay as it is but there's something else. I swear to god she was a cardiophile just like us. Almost every cuddle session we had that semester usually involved one of us commenting on how much we liked listening to each others hearts when our heads found the correct position. I would be nestled up against her chest and tell her how much i loved listening to her heart beating, how it soothed me. She would do and say the same, often staying in the position listening for 30-45 minutes at a time. We abruptly ended our friendship as soon as the semester was over and we never remained in contact. It was a fleeting physical friendship, and I loved it for what it was.
