Extra Service - Bi-Urge

So I'm from Switzerland and work as a nurse. I work as a "home treatment" nurse, so that means that I visit my patients at home to get them the treatment they need. I work with a high class treatment agency, so most of my patients have more than enough money. Sometimes you spend a few years treating the same patients, as you can imagine the work gets more personal that way. So I got this patient, I was 22 when I started working for him. He was 41 at that time, lets call him Andrew. Andrew is partially paralized and his wife does not want to take care of him herself so she hired me to help with that. Andrew has made a lot of money in the past, so I assume thats the reason why his wife stays with him. By the way, Andrew is not in any way mentally disabled, its strictly physical. So my work with Andrew contains of helping him shower and shaving him. So me and Andrew got a long pretty well. After a few months of visiting him nearly every day, I was once again shaving his beard (he always wants to shave before he showers, don't ask me why) and he started talking foolish about his wife. He said that she does not want to get physical with him anymore and stuff and we kept talking. So he says that he has a lot of pubic hair and maybe thats the reason why his wife isn't interested in him anymore. He said this in a joking way but I said that I can shave the pubic area for him. I said that this is a part of my job and if this helps him feel more comfortable in his own skin I would be glad to help. First he was kinda hesitant but after a short while he agreed. He asked if I can shave him with his gilette razor after showering, which I did. So while shaving I once grabbed his cock to better be able to shave the top of the shaft. He told be to do it that way, so I did. While I had his cock in my hand I could feel him hardening up very slightly and that moment was kinda complex for me. I work as a nurse for almost 8 years now and I'm used to naked people, genitalia, sexuality and stuff. Never before have I got "forbidden" arousal while doing my work. So in that moment something like a strike of lighting shot through me. As I felt that little response to my grab I felt a lot of pleasure inside of me, my breathing got quicker and my crotch area felt really warm. So I don't know why but when I felt that impulse from his dick I automatically firmed my grab. That caused him so swell up more, followed with me tightening my grip and so on. That little sequence happend in maybe 1-2 minutes. When I took my hands away his pubic area, dick and balls were shaved and he was fully erect. He joked about it and said that this is a sign of a wife who loves money. I helped him dress up and helped him to walk to the couch to lay down for a bit. I went to the bathroom and while taking down my pants to sit down I realized that my undies were stained all over with precum. I took a piss, got up, finished my work day and went home. Fast forward two weeks later I was at Andrews again. While he was undressing for his shower (somedays he can take off the shirt kinda by himself) I asked about the shave down there and if it has worked to charm his wife (in a joking way). He said something stupid which I don't remember and a few minutes later I was showering him. While washing off the remaining foam of his body I take a glimpse at his dick and I see that his dick his beginning to get hard. He said that the shaving trick hasen't worked so far, I said that he should not worry, laughed it off and kept on doing my thing. After drying him up he was sitting nude in front of me while I was drying up the space between his toes. As I look up I stare directly at his cock which was hard the whole time. I felt that warm feeling in my crotch again. While staring at his dick I noticed that a small drop of precum was sitting at the top of his dick. I never had any gay sex or feeling before so that shook me once again. I don't know why I did it but I instantly went up there with my head and took his cock in my mouth. I instantly liked the taste of his freshly showered warm hard dick. I sucked his dick very passionately and after what felt like two minutes he begun to moan. I could feel that my undies once again were getting wetter and wetter. I focused on the head of his dick and worked that thing until he came in my mouth. I can remember very clearly that 4 big spurts of sperm hit the back of my throat and the last two spurts covered the entirety of my tongue. I swallowed every little single drop of it. Right after I swallowed I stared at him, we made eye contact. Nobody said anything. I helped him to dress up completly and hours later left work. That blowjob happend in the end of sepember 2018 and a few days later I noticed that I had 1000+ CHF (swissmoney) with the marking "Extra Service" on my paycheck. We until this day
have never talked about me getting him off. Since then I swallow his cum on my nearly daily visits whenever I got the urge to do so. Sometimes I don't suck him for two weeks and sometimes I suck him daily weeks on end. And so he always gives me a nice extra service fee on top of it, regardless of how many times I suck him. This has been going on for about two years now and it looks like this work relationship will continue for many more years.
