Surprised By Sister in Law

This is my first time writing to such a site.
This happened one morning just after having received a call from my doctor's office to inform me that my sperm count test came back and it was still positive. I had been waiting for that call for more than two months 'had a vasectomy'. The secretary told me that I could bring another sample at any time since the two month required between tests had past. So I thought to myself, I could do that now. My wife is at work, the kids are in school and I have the day off. I got my little specimen jar, striped naked and laid down on the sofa.
I had been going at it for about 5 minutes when my sister in law walks in, what a shock! She just looked at me and said not to mind her because she came to use the computer and figured that nobody would be home at this time of the day. We had all seen each other naked before and she knew why I was masturbating as soon as she saw my little pink jar 'not that I ever needed a reason to J/O' because her husband had gone trough this last year.
At this point, I lost my erection. She said she was sorry and started to leave. I told her she could stay and do what she needed since I was now soft. She replied that she would only stay if I finished what I had started. I did not know what to say or do because I have never masturbated with a person in the same room as me before, never even got caught, I started masturbating at the age of 11.
I said OK but it would take me a while to regain my form. At this point, she stated to walk toward me and removing her t-shirt to reveal those beautiful breast of her's and saying that this was the least she could do to help 'She knew I was a breast man'. My erection was back with a vengeance. I can't believe I'm going to masturbate in front of my sister in law.
She said, WOW that didn't take time! I took my penis in hand and started stroking it. Two minutes later, I shot my load all over my chest. My sis in law stated to laugh. I asked what was so funny? She sits down on the edge of the sofa, reach's over my sperm covered chest and gives me a little pink jar that was still on the sofa. In all the excitement, I totally forgot about my little jar and had to wait two more days to bring in another sample.
This was by far the MOST memorable day I ever had masturbating because when my wife arrived home from work, and I told her what had happened, she asked me to do it again in front of her. She knew I masturbated in the shower and had alway's wanted to ask me to do it for her but feared asking. She did not find it just that her sister got to see me doing what she had often fantasised about over the years.
P.S. getting caught is not all bad.
