The girls licking each other, the men fuck each other

Two couples a weekend camping in the woods. The beautiful weather invites a horny afternoon sex. Arrived at their tent, they start, called the warm weather, to arouse each other. They go further and it is not long before it is clear who is doing what. The girls licking each other, the men fucking each other. It is a pack of horny activity when they are joined by a third man.
