Lost a bet

I work with this guy He is 18 I am 28. We are very open and talks about everything
He always is bragging about his manhood size and saying that is what the ladies like. He said he is 10in. I always tell him he is full of it. I also tell him as a gal 10 would not do it for me. He said that’s because I have never had one that big. He is correct I have seen my share but no 10. I believe 7 was my biggest
One day I finally said you are full of **** let’s see it. He said if I did I had to have sex with him. If he lost he had to shut up about it. Well he did have it

I was surprised to say the least a young guy could have that much (**** how much bigger is he gonna get)
So I lost the bet and paid up.
I can say this young guy was right. It was a slow take at first but that is another story I didnt know what I was missing
