When he got downstairs he was shocked at what he saw, their were 4 sexy adult women in his living room wearing nothing but what looked like a stripper's version of a harem outfit, a bra and panties with a short see through skirt-like part, one was wearing red, another blue, green and the last in black.
Just by looking he could tell somehow, that it was his family, they didn't look similar, but because of his wish, he could tell who was who.
The one in red said "Jon what's wrong isn't it Harem day?"
"uhmm yeah gimme one sec," jon said running into the kitchen where his family couldn't see him and said quietly "I wish I knew about Harem day"
Jon found out that one day he asked his family to all become sexy women and serve his every need and it had become a common thing, most of the time he changed himself into a very manly man among men, that's why his Mom was confused.
he changed himself making his muscles larger, himself taller, his face more rugged and his Dick larger, then went back to the living room to be waited on.
