Persuaded my blonde sister to show her cap and have sex

A pretty young blonde came here from another city to stay with a friend. Today she got out of the shower and wanted to go make herself some coffee, but she ran into her friend's horny brother. It turns out they were at home together. As soon as the guy saw the blonde in only a towel, he immediately wanted to see what was hidden under it. As a result, he persuaded the blonde not only to show off her charms, but also to have sex together with hot oral sex.
