Until a few years ago I had not masturbated in front of my wife. I had not been able to pluck up the courage to mention it even though I wanted to.
After having a vasectomy, though, I received a letter from the clinic, which said I must provide a semen sample to test the success of the operation. It said that on a specified date I must masturbate into the small container which the clinic had provided and then send it to the clinic for testing. I looked forward to the date, which was just a week away.
On the day my wife said, 'Today is the day you have to do your sample, remember.' Of course I had remembered. We started to discuss the process, which made me feel more eager. 'When will you do it?' she asked, 'and where?' It was the middle of the day and we were sitting in the living room. 'I'm ready to do it now' I said. 'What here?' she said. 'Why not, there's no time like the present,' and I stood up, undid my pants and pulled out my penis. It was a bit floppy at first but I soon got it hard by playing with it. 'You better get the little bottle,' I told her, which she did and she sat down in front of me poised at the ready. I was standing facing my wife masturbating away and didn't even bother about the possibility of neighbours being able to see through the window.
'You best let me know when you are about to ejaculate,' she said as she held the small container closer to the end of my erect cock. I was feeling more and more aroused and rude and told her I was getting near to cumming. She put the container right up to the tip of my cock just in time as I felt myself get really hard I held my cock tight as it throbbed in my hand and semen started shooting out in several spurts, some going straight into the container as my wife tried to catch as much as possible and some missed and went onto the floor and some on her skirt.
As we both enjoyed the experience and had fun doing it we have done it again for our own amusement on several occasions. Sometimes my wife will hold a milk bottle for me to masturbate into. Other items she holds to catch my semen have been, a pair of her knickers, a wine glass and on one occasion after we had been talking about sex for a while downstairs I simply stood up, got out my cock and started jerking myself off the same as the day I did my sample so she acted quick and took off her shoe for me to cum in. I pointed my cock into her shoe as she conveniently held it out and I shot my sticky load inside. She was so turned on by this experience that she put her hand down her pants and brought herself off.
Here's looking forward to providing more samples of my semen just for our pleasure.
