To find the flame of our sexual relationship, my wife and I usually invite unknown girls to our house for provocative and exciting threesome sex. Recently, we discovered that there is an agency to hire prostitutes for that reason, so instead of looking for unknown women on the street, we hire girls who are willing to make some extra money in exchange for being part of a sexual encounter with us. My wife and I, discreetly, start having sex in the middle of the room to suggest directly that she joins us. My wife, completely naked, sits on my cock and moves her ass to find out for herself how many times. At that moment, the maid approaches and, with a push, removes my wife to suck my cock in a delicious way. Then both of them joined in the encounter to give me the best experience of my life.
