No parents, but my brother's home: "Come here, you owe me cunnilingus and orgasm!"

It's a good thing I'm not a sibling. I can fuck my girlfriend and sister in peace

What, sister, you saw a dick and now you're not laughing? Suck it

Friend girl, you say your brother has a great dick? Go ahead, prove it

Father and son want to know whose dick is bigger, not to do puzzles
