Older Sister's Boyfriend

Louise is chatting to her friend about her older sister's boyfriend who apparently has a big dick. Just then he walks in and the girls blush. They admit what they were talking about and ask if they can see it. He says no but they strip off to encourage him. With the two young girls in their lingerie he drops his trousers and their eyes bulge at his thick dick. He jerks off so they can see it erect and when they bend over and stick their asses in the air he shows them a huge cumshot!
