If I found out my sister was a slut, I would have pulled her in the asshole, too. For these guys, getting their asses handed to them is commonplace. Although for the look, they break for a few minutes, but when a couple of drops of lube appear - they quickly sit down anally on the phallus. So this little sister is nice to feel like a courtesan, to show off all her skills in front of her brother, to let him cum in her ass. Every bitch dreams of being the best at it.
Dude got lucky, he fucked two blondes right away in their luscious asses. At first he let them suck his dick to be polite, rubbed their firm asses and tits. The funny thing was that the girls didn't compete with each other, but fondled, rubbed their clit, sat next to or on top of them, kissed, held their throats, all for the sake of the partner having a vivid orgasm in the process.
