Walking the dog

A man is walking his dog, a Rottweiler, through the forest on a hot summer’s day when he comes to a clearing. In the clearing there’s a natural pond so he sits by the water, just enjoying the view and the peace, his dog lying by his side. He hears a noise and turns round to see another dog, a Golden Retriever, coming through the trees, followed by the most beautiful blonde woman he’s ever seen.
The women smiles and sits next to him, seemingly also enjoying the view and the peace. After a while she points at their two dogs lapping at the water and she smiles and says “They’ve got the right idea”. She takes a couple of cans of beer from her backpack and passes one to him. They sit there in silence for a bit longer, sipping their cold beers.
Then the woman points at their two dogs, now swimming in the pond, and she smiles and says “They’ve got the right idea”. She strips down to her underwear and slips into the water. The man quickly strips to his underpants and dives into the water, which is cold and refreshing.
After a few minutes of splashing and swimming, the woman again points to their two dogs, now on the grassy bank by the water, fucking vigorously, and she says “They’ve got the right idea”. She languidly climbs out of the water, slips out of her underwear and lays on the grass, waiting.
He can’t contain his excitement, so he too climbs from the water, removes his underpants and lays next to the woman, turns to her and says “Are you sure your dog won’t mind?”
