This is a great story. It is unfortunate you couldnt have the opportunity for sex with her due to her boyfriend, but I can understand that. The tickling play and incredible sexual tension between you was fantastic, though, and it is great that you at least got in such good tickling and foot worship in with her. I had a similar experience like this in college, although the tickling was not as intense or sexual as your experience was.
There was this girl Lora who I used to spend time with during my freshman year. Lora and I had great communication, and there was quite a sexual tension between us also. The problem was that I, like her, was a freshman, and she had a thing at that time about being with older guys, so she didnt want to date me as a serious boyfriend.
One night I was spending time in Lora's room, as I often did, Lora lied down on her bed and asked me to give her a massage. I happily accepted, as I massaged from her neck, down her back, and legs, and so forth. I wasn't really into tickling at the time, but when I got to her bare feet, I picked them up, and started massaging them, and couldnt resist having my fingers dance over her soles some. Lora burst out in hysterical laughter, scrunched up her toes, told me she was really ticklish, and that if I didnt stop tickling her, the massage would have to be over, because she was very ticklish, and couldnt stand to be tickled. I then went back to the business of finishing the massage, more excited then of being able to touch Lora's bare feet, because I was more into feet back then, and not tickling. While Lora and I did have some more encounters during our years at college, and there remained a sexual tension between us for a long time, never again did we get that close, or did I have the opportunity for a massage or tickle. It was a brief one, but memorable. The best part for me was not only the massage and the sexual tension, but also the spontaneous tickling and the reaction she had.
