My wife and I married 9 years ago. I'm 4 yrs older than her. Around a year after we married one of her friend's husband turned up with testicle cancer! He had surgery soon after that, and had a tumor removed. It didn't work. To keep it from spreading, the Dr's ended up casterating his left testicle. Within a year, he started habing issues with his right testicle, and within 6 months he was totaly casterated. He now takes shots and can get it up, even have sex, and shoots a load of blanks.
Since all of this started my wife has taken a keen interest in my boys. At first it was after sex, when they just hung loose. Or in the shower. She would come in soap me up and roll them around. Or if it was summer, after working outside, she would corner me and say "Since they really hanging low lets give them a roll".
Then in the summer 5 years ago, her sister (3 years younger than her) was over and they had been drinking wine since lunch. After grilling, I went back to working in the yard. Around 6 I started getting hungry so I put everything up and headed for the shower. As I got to the door, my wife stopped me. She said "Come her big boy, it's time for monthly roll!" As it was very obvious they were drunk I told her so. She said they had been talking about checking for cancer, and since her sister was engaged to be married in another year she needs to know how to protect her man's jewels! Then they both laughed. I started inside, but she grabbed my wrist and said seriously, stand here! So there I was my wife was to the right of my right hip, her sister arms lenght in front. The wife unfastened my belt, her sister unbuttoned and unzipped my shorts, then stuck her thumbs in side the waist band on both sides of my underware, and pushed them to my knees. Fortunately it was still very hot outside, and I was worn out from the sun and yard work, or I would have been rock hard.
The first thing her sister said was Wow, his balls are a lot bigger than "M" (the name of her fiancee)! Before my wife could say anything her sister had the boys resting in the palm of her hand, gentaly moving them up and down, as if to determine their weight, all this and with a big grin on her face!
So my wife reached out and started giving her instructions, rooling them around between her thumb and fingers telling her what to check for. Then she had her sister give them a roll. As soon as she started she used way too much pressure and I flenched and it popped from between her thumb and fingers, I bent over in pain and said oh shit! She said I'm sorry, I'm so sorry! My wife said, in an almost laughing manner oh that's ok, just use a little less pressure. Then my wife reaches out grabs my shirt and pulls me back, all the while laughing. I had turned away in pain and was holding on to another chair. Then she said you have had far worse happen to them just man up and get back here.
After a good 20 to 30 minutes of instruction and practice, I went in and took a shower.
So I found out around 6 months after that my wife was over at their appartment, she and her sister were in the hottub drinking wine. Mike joined them with a beer in hand (college football game was over) and around a half hour later, they went back in their appartment. Her sister made Mike strip, so my wife could give his boys a roll because her sister wanted to know about a specific feature she was feeling on his right nut. Around a year Later when my wife finally told me about it, she said "Boy her sister was right! Mike does have small nuts! And his penis isn't near as big as yours either!" Then she laughed. I asked how did you know that? She said oh he got a hard on pretty quick after I started handeling his boys. Well he did have something, there, so he went to the Dr. Turns out it was just a cyst and was taken care of in the office.
Now my wife and sister in law don't really drink more than maybe a glass of wine at a time, but about everyother month they might. But when they do, if it is just them and either Mike or me, testicles will be double checked. Mike dosen't know I know. He dosen't know his wife has played with my dick, or about 2 years ago I got a big hard on, the first time in front of his wife, and now she knows how much bigger I am then him. Since then my sister in law does her best to get me hard when the roll the boys. Most time they succeed. I have to say my wife's sister is a really hot bodided woman with a very pretty face
