You've been doing remote sessions with a marriage counselor, and she suggests that you and your wife try an unconventional new treatment that involves the two of you becoming VERY comfortable with nudity and sex. She tells both of you to strip down to your underwear while she does the same, then encourages you to touch yourselves sensually while she does the same. Soon all three of you are naked and touching yourselves, and then she directs you and your wife, telling you what she wants to see the two of you do, while she masturbates furiously, enjoying herself in a manner that, although perhaps somewhat unprofessional, is certainly therapeutic for all involved.
