My Sister’s Huge Tits Are Hiding A Secret

My dad just got remarried and let me just say I wish he had remained single. I mean his new wife isn’t bad. Shes nice. Kinda boring but nice. But unfortunately she wasn’t the only person that came with this deal. Thats right. I have a freakin new sister too. Aint that great -_-. Everybody thinks my sister is such a good girl. Cuz she’s smiley and pretty. And yea she has really big tits. They’re massive. And she makes sure to show them off in everything she wears. They’re so jiggly. They bounce all the time whenever she moves.
