I separate this post a bit,to tell you we had the final talk with my parents about Emilie's chastity belt,and we agreed to the rules.
After a talk to remember well the rules and consequences(good and bad ones)for us,my parents asked both of us if we understand these,and if we agree,and both of us replied yes to both questions.
Then,my mother and me measured Emilie(my mother remembered how to do it very well),in private,in my room(and my mother took care not Emilie nor me try to cheat to make Emilie's belt less secure),and,then,it was ordered.She check the measurements three times,like she did for me,too,so it should fit Emilie well,and not be too uncomfortable
Emilie will have the same chastity belt than me,waist one,with the cable.We tried to tell to my parents it may not be necessary to order a secondary shield for her,but they didn't agree(we were sure they would disagree,but it was worth trying!).It should be delivered in 2 to 3 weeks...We're a bit nervous,and Emilie is a bit afraid,but,now,it is done.
