Veterinary school

My sisters was going to school to be a veterinarian, she came home with some of her classmates they were learning how to castrated animals with a band. They had a sock with two balls in it to practicing put a ban around it to assimilate castration. They started talking about wishing they had something real to practice on.

That's when my mother said just use your brothers, she told me to stand up and take off my clothes I stood up but I didn't want to take off my clothes in front all these girls my mom said don't make me tell you twice so I did all the girls started to laugh. Each girl took turns banding my balls most of them were nice about it one girl squeeze my balls as she pulled them through the band thought was going to pull them off I cry out in pain they laugh she asked did that hurt than she to remove the band she squeeze my balls even harder and pull them down as she laugh she said sorry I got to get the band off. As I laid there naked hold my balls thinking it was over. My sisters said I bet if we take him to class and do it in front of everyone we could get extra credit. The next day mother took me to the school . I had to undress in front of everyone one girl asked why is it so small everyone laugh. The teacher said everyone could have a turn banding my balls after the last person got done instead of removing the band. My sisters wanted everyone to take a picture with me they all did. My sisters said she would remove the band when got home i went to to grab the bag with my clothes in it my mom grabbed the bag and push me out in hall as I walked down the hall naked and my ball band and turning purple I try cover my balls with my hands my mother slapped my hand away she didn't have to say anything i knew she wanted to humiliate me and let everyone see my small manhood. Afterwards my mom took us out for ice cream with some of my sisters friends my balls were throbbing so bad but knew I couldn't asked them to take the band off noone said anything about why I was naked or why my balls were band my sisters said were else can we take him to see if anyone said anything they took my shopping I got to hold there bags my balls were almost black now people pointed and laugh and took pictures a lady did come up to us and said we we really should do that to more man my sisters said we're going take the band off later the lady replied with leave it on the penis is so small it not going to be good to any woman after taking me to more store we finally went home I begged my mother and sisters to take off the band they laugh and said let's take a vote does anyone think he should keep his manhood know one vote for me to keep my manhood i when to bed knowing my balls would be gone by the morning
