You can't trust blondes. She's willing to give her brother a new haircut between her legs just to be appreciated. I understand him - it is impossible to break away from such a body, even by force of will. And then we wonder why some chicks don't give it up on the first date. It's because they have brothers who string them up before they do!
Girls want to be models, so they're ready to get on any dick that will get them a job in the modeling business. To suck or not to suck penises - such a question does not exist for them. Everyone sucks - just not everyone flaunts it. But not all of them are willing to let you work on your sweet pussy. At least the girls should be given time to get naked. There's no time to think about it. You got to ride the dick.
The sisters are totally different - one is active and energetic, and the other is quiet with glasses. And the second was afraid to have sex with a guy - even her panties were not sexy. But still even she got aroused when the guy started fucking her sister in the asshole. She licked his dick before doing it and started squeezing his balls. Just like that, the quiet girl joined in. And I hope she didn't regret it. The main thing is to start and suck in time!
