Neighbor hears our loud sex and joins in with my girlfriend

My main girlfriend and I, as lovers, are trying to have a good time, indulging in sex. We both love to fuck, so we do it very often and at that moment we were doing it at home. Our friend came to visit us and decided to join in our fun. The girl was not against it and began to caress her pussy. Soon our neighbor heard our loud screams and came to see what was happening.He could not resist the sight of two naked girls making love and joined in. He began to rub his cock on the wet pussy of one of the beauties. The guys started fucking our girls, they took off their clothes and began to fuck them hard. The girls were moaning from pleasure, and soon all four had a wonderful orgasm and a flood of sperm.
