This happened mid 1999, about 10 months after a fairly sexually active 3 month long relationship with my sister. We both called it off in the end because we both were getting involved with another partner.
I have always enjoyed giving and receiving erotic massages for the last 28 years when my partner, that I was living with at the time back in 1992, and I did a 3 month training programme in Swedish style therapeutic massage. We used to give each other a regular therapeutic erotic massage with lots of teasing. Most of my girlfriends since then, that have been more than a one night stand, have had a Tantric-Swedish style erotic massage from me.
My sister, who is 3 years older than me, knew that I did a little bit but she had never tried one either from myself or anybody else.
She gave me a ring to say that she had been skiing the previous day, went over a jump, landed backward on her back and somehow pulled a muscle in her groin. She wanted to know if I could have a go at massaging it to make it better. I told her she was best to visit a trained physio or massage therapist since the type of massage I did was a little bit therapeutic but more sensual - erotic type and the courses I took part in were for amateurs not professionals.
She said she was too embarrassed to see a professional in case she had to go nude, then said her boyfriend had just clean shaven her pussy last week was a bit embarrassed to show it off where as I had seen it all before. She really wanted me to give it ago. I couldn't tell her what to expect from a professional so I told her ok but if
I could not make it better she had to a get proper treatment done. She agreed to that but wanted me to look at it asap.
I cancelled my dinner date for the next night and told my paranoid girlfriend that I was busy. She demanded to know why implying that I was playing around behind her back so I just told her that I was busy with minor emergency with my sister for the night. Blood is always thicker than water.
The night before I had gone to an indoor climbing wall with a friend and she treated me like I was having an affair there as well. This relationship of only 6 months was doomed to fail as far as I could see and had all but given up on it due to her overly possessive nature. I was surprised we lasted this long.
I hung up the phone then went find some of my old notes about how to massage the groin area. We learned a bit about it in one of the courses that I had done but never tried it since.
I got home from work the next day, had a quick bite for tea and heated up the oil and bedroom.
My sister turn up limping about 6.30pm. She had had the last day off work. I got the bed ready with a towel so she could lay on it. I got her to show me where she was sore, at the top of her right inside leg at the front to the inside around the join. She removed her jeans and lay on the bed. She had quite tight knickers still on that showed up her camel toe in a lot of hot detail.
