As he went out he heard his sister's friends giggle and laugh once a again, no doubt thinking of having seen him naked and erect before. Little did he knew that the reason he managed to get the shorts on so easily in the end was than the back of the shorts gave up.

Those were shorts his sister had worn for intense practice multiple times a weak for years, that had been washed hundred of times and that he was wearing despite being too small for him. The seam going from front to back had given up from the belt behind him to between his legs.

The girls had noticed but didn't warn him, not wanting to spoil the fun.

The Petersons, Oliver and Gloria were a couple of old people that were friends of the family. His sister and him considered them nearly as their grand parents. They had a little niece of K-T's age named Lily that sometimes spent time with them when her parents had to work abroad.
