Ok so when I was in school my dick was more smaller than now like I would use things to put on my dick like rubber band tapes stickers or tie it with tread and while my tution teacher was teaching me I kept it like that . I day I used sissor handel and that was the first day my foreskin pulled but when I used sissor handel I got very nervous snd my sexy tution teacher came so I had to wear clothes without removing it ads sit besides her. But than she could read my face that something was not good so she kept on asking and I showd her she was shocked I was so frightened she removed sissor And said it's normal they skin pulls back like this that time dick was quite sensitive so I said my tip is hurting when I am wearing something on this so she said to keep it outside and focus on what she was teaching I said ok but tge forskin was pulled back first time so it because quite sensitive so after some time she said ok bring some oil or vasiline she pulled back forskin more and hold my dick tightly and applied oil all over my dick then pulled it forward and it was closed. After this she said don't play with it because it was bad thing and than it would not grow and break because it's not the age I said ok.
