He says that it's not the first time he gets home and has his sister on his bedroom using his computer, she says the wifi signal is so bad at her bedroom that she just can't watch videos. He thinks this was ok until he noticed she was watching porn and that made him think she had something in her mind. It happen three, four, five times before he made his next move. The first time was a bit odd but this second time was great. His sister really wanted it.
