I'm not aware of any movies specifically with a 'sexy sis story' as that might imply inappropriate or unethical themes. However, there are many family - centered movies with positive sibling relationships like 'Little Women' which shows the strong bond between sisters in a more appropriate and heartwarming way.
There is also 'Margarita with a Straw' which delved into themes of love and self - discovery for a woman who happens to fall in love with another woman. It gives a more nuanced view of same - sex relationships in an Indian setting.
I'm sorry, but I don't have specific sexy bratty sis stories to recommend. However, you can try looking in some teen - oriented fiction collections that focus on sister relationships with a bit of a feisty or 'bratty' angle. Just make sure they are appropriate for your age and reading level.
You could try books like 'The Chronicles of Narnia'. It's a classic series full of adventure, magic, and great characters. The story takes you to a different world where there are talking animals and epic battles between good and evil.
One great movie is 'Precious'. It focuses on the story of a young, overweight African - American girl facing many challenges in her life. It's a powerful drama that shows her journey of self - discovery and empowerment.
The book 'Fifty Shades of Grey' is a well - known sexy love story. It has a lot of steamy scenes between the main characters, Anastasia and Christian. Another one is 'The Notebook' which, while not as overtly sexual as 'Fifty Shades', has a very passionate love story that spans years and is full of emotional and some sensual moments.
One movie could be 'Brokeback Mountain'. It has an intense and emotional story of two men's relationship. The scenery is beautiful, and the relationship between the characters is full of passion in a subtle way, which can be considered as having a certain'sexy' or 'erotic' undertone in the sense of the deep, unspoken attraction between them.
One movie that might be related is '500 Days of Summer'. It's about a relationship that has a lot of different feelings involved, including some aspects that could be seen as a love - hate situation. The movie explores the various stages and emotions within a relationship in a unique way.
Well, there are many innocent 'big sis' stories. For example, a story about a big sister who takes care of her younger siblings during a difficult time. She helps them with their homework, cooks for them, and protects them from bullies. It's a heart - warming story that shows the love and responsibility of an older sister.
Another one is '9 1/2 Weeks'. It's a film that explores a passionate and somewhat kinky relationship. The scenes in the movie are very sensual and it shows a very intense relationship between the two main characters.
I don't have any real 'sexy sis stories' to share as this can be inappropriate. However, if we talk about positive sister stories, there are many. For example, a sister might support her sibling through a difficult time at school by helping with homework or standing up to bullies.
