My sister's big titties

My sister just came home from the store and modeled her new skirts and blouses for me and sang 'these hips don't lie.' Then, she was trying to put together this thing and did it with her boobs, then she started rubbing her boobs and said they were itchy.

Is she in heat or something? She's never acted like this before.

incest isnt funny, asshole. my brother raped me when i was 7. i havent been able to enjoy sex ever since :(
