HUNTA-863 Take your friend home to fuck your sister while the whole family is away

My sister was a very serious class president and a typical honor student in both appearance and content.

But she was bullied and ordered her sister to sleep with sleeping pills. Then, on the first day, her sister was picked on by bullies while she was sleeping.

The 2nd day she hated her, but if she kept fucking her, she started to have feelings for her Already. On the third day, her sister was transformed into a ridiculous crazy Ji Po that she asked for herself. I can't believe that my sister is so erotic and I don't want to believe it.
