How Many Times Could I do it in a Day

I posted this as a reply to a forum question about getting caught. Then, being not an expert at this site I posted it as a comment. I think it is more of a story than anything so I am posting it here. When I was a teenager at home alone during the Christmas holiday there was little to do to fill my time. At the time I lived with my Dad and spent the day at home while he was at work. One day I decided to see how many times I could masturbate to the point of ejaculating. Being a teen it did not take much to have me squirt my load. That day I tried everything I could think of. First I tried to see how quickly I could make myself cum. Then I would try to see how long I could masturbate without cumming. I tried a carrot up my ass. I tried masturbating with and without lube (all we had was Vaseline). Basically I tried everything and was having a great time but I found that my dick was getting chafed and after the 7th time it was getting difficult to cum. So there I was with a rather sore dick but still with 2 more hours to go before dad came home. I had put away the Vaseline and carrot and other things I had experimented with but I wanted to get at least one more orgasm in while I had the time. I sat naked in the big reclining chair in the living room and started to stroke my dick, taking my time as is was getting really tender. My eyes were closed and I had found a rhythm that was just bliss as long as I did not go too fast. I shot a much smaller load that I had earlier but it was still enough to land on my cheek and chest, as well as run down my hand and dick. This is how I looked when my dad walked in having left work a few hours early due to the upcoming holiday. He looked at me with the cum on my cheek and chest and hand. I was too embarrassed to move or speak or do anything. I was naked with nothing to cover up with and nowhere to go, and covered with cum to boot! After a few seconds he said, "There are only two kinds of people who masturbate, those who admit to doing it and those who don't." Then he noted that by the look of my dick I had given it quite a through workout and that I should use some lube if I go at it again to that extent. Then he went to his room so I could get up and clean myself up. Later we had a talk about masturbation and sex in general. He told me that if I wanted lube or condoms to put money on the kitchen table and he would pick up the stuff for me and put it in my room without questions or discussion. Until I could get the stuff for myself this is what we did and it worked for both of us. Also, I followed his other suggestion, I stopped masturbating in the living room and kept it in my own room with the door locked of course. That day I came more times than any other in my life. What a day it was!
