This couple of adults have been married for over 6 years and are beginning to have sexual problems. It seems that they can’t maintain an erection for very long, so the expert starts asking many questions to get to know the peculiarities of each partner. The medicine prescribed by this expert bitch is to join them during sex to observe it and thus identify the problem. The problem is that they apparently behave very well, and the expert starts to have a great time and can’t stop, ending in a completely out of control threesome that’s very exciting to watch.
