The girls were looking for fun, riding in the car. Sometimes they got themselves excited. Apparently they wanted a new sensation, so they offered a threesome to a strange young, handsome guy. After some persuasion and conversation, he agreed and went straight to work. The girls hooked up with him, gave him blowjobs, rolling on top, while two were fucking, the third fondled the couple.
Daddy sure is quick - got in and fucked his daughters like whores. But then again - he's responsible for their upbringing, so he's entitled to it. They even observe the line to get their pussy in. Sluts need society, too, and he can teach them to be their best. And I think - he's succeeded. I see they deftly worked his cock and even enjoyed it when he cummed in their open mouths.
