Having my fun as a mother at home.

Im a 35y mother with a daughter and a half son, we are all really close and share basically everything, When my son turned 18, he asked me to make a random post and the amount of likes it got, turn it into the amount of kicks I shall give him in the balls, at first I was surprised by his request but at the same time was curious so I agreed. The post got around 580 likes in the house of 2 days when I told him he was surprised and a bit scared on his face, so I asked if he still wanted to go through and he said yes. I told him that I would give 50 kicks 58 kicks per day so it would be 10 days in total he agreed, the days went pass and it was becoming quite fun seeing his face and reaction I would usually have him stand in the living room while his sister was out, but one day she came back home wiout our notice and caught us. At first she was all confused as why was her brother in his underwear getting kicked in the balls by me, so I explained the what and why, after a while I asked her if she wanted to give it a try, at first she was hesitant but I told her it was fun. So she gave it a try for our surgery she actually liked it and asked if she could do more so i ask my son if he could take a couple more hits even though he had gone through the 57 we agreed on, he agreed even though he would complain after each kick. We both just keep laughing till we saw something growing in his underwear, we look at each other and wiout saying a thing, I pointed to the roof and said what's that! While his sister when behind and pulled his undis down, that wen we saw it a tiny boner, we laugh and laugh at it and even decided to give his balls a hard squeez for having such small dick. Now due to the fun that we have we have decided that as punishment for asking such thing and for being a useless punk he has to stay naked in the house all day and be our little stress ball to use when ever we want. I have been searching and maybe to make things more fun for us two girls we might buy a little shock collar to go around his balls, just to have a little more control and fun when ever we want. Who know.
