Mature Swinger Couple

Carine and Marcelo were a liberal couple, 46 and 48 years old respectively. They had been practicing swapping and threesomes for 5 years. Bored with the monotony of monogamous sex, they began to explore the swinger world and could never leave it. Carine felt totally bisexual and she enjoyed being with women her age although she liked girls much more but they weren't very lucky to meet younger couples or girls.
Marcelo was curious about men but had never been encouraged. He was very horny to see how good cocks fucked his wife, more than once he imagined trying one of her but it was no more than a fantasy.
