I had a bit of a problem but because I was too embarassed to mention it, it went undiagnosed until I was 17. At that point, my mother, who managed a major department store used her pull with one of the frieght companies to get me a job. I wasn't very good at the job, sso when the freight company's policies required me to have a full physical, they made me go to a doctor who discovered that I had a hydrocele of the right testicle which made it enlarged. The physical, which I failed, gave the frieght company an excuse to get rid of me. When my mom found out that I'd failed the physical, the frieght company told her the results. It was probably illegal for them to release the information, but in those days, privacy wasn't nearly as well-protected, and they told her about the issue. When she came home, she came to my room and asked me about it. I felt horribly embarassed talking to my mom about my genitals, but had to tell her all about it. She, very reluctantly but determined, asked me to show her. I initially refused, just saying "I don't want to", but when she persisted, I relented. I pulled down my pants and underwear and laid on the bed with my cock and balls exposed. I was completely torn....horrified at showing my mom my cock, but at the same time, thrilled at her seeing it. She sat on the edge of the bed, and shyly asked me what exactly was wrong. I lifted my cock, which thankfully wasn't aroused yet, and moved it to the side to show her my sack which was quite enlarged on the right side. She looked at me, and then tentatively touched my right testicle. That was all it took for my cock to react and I started to develop a major hard-on. She asked me if it hurt, and I told her that normally, it didn't but if I developed "blue balls" (which made me flush with shame), it hurt a lot more than normal because my testicle on that side was enlarged. I felt horibbily embarassed, but told her that if I got aroused and didn't resolve it by jerking off that it ached fiercely for hours. She continued to fondle mt right ball for a minute and then said haltingly that I should probably "bring myself off" so it wouldn't hurt. I was shocked....lying there with my pants down, my cock so hard it was throbbing, precum starting to leak out of my head, and my mom looking intently at it. I was beginning to wonder if she expected to watch me jacking myself off, but she got up and said something about starting supper. When she walked away, I didn't even think about it - I started stroking my cock. I'd always tried to conceal any evidence that I masturbated, but at this point, I was long past that. As soon as I started stroking, the heavy flow of precum made it really obvious that I was jerking, and I could hear the noise as I fapped and felt curiously thrilled by the fact that she could hear me. I started to cum almost immediately, but kept stroking my cock in spite of it. The heavy cum made it even more obvious what I was doing, but I kept stroking until I was right at the verge of cumming again when she suddenly came in the bedrrom door and said that supper would be ready soon. As soon as I saw her and realized whe was looking at my cock, I started to cream again. I saw her watching as I throbbed and started oozing a heavy load of cum again. It felt like it went on a long time, but she watched until I'd throbbed about fifteen times and finally exhausted my load. I looked up and said something about being there soon. She didn't retreat as I'd expected, but came in and knelt down to wipe the cum away and dry my cock. It was probably one of the finest moments of my life as I watched my mom wipe the cream way from the tip of my cock and then playfully slap my cock and tell me it was time to get up. I felt happy and satisfied in a way that I'd never felt after I'd shot a load, and slowly (wanting to draw out the experience) pulled my pants up and zipped myself up. I realized that I loved my mom watching, and even more that I love her touching me there.
