Scat Couple
There are many dedicated to the hidden pleasures of scat. Two people in a relationship who have the same dedication are a "Scat Couple" and share their shit with love, usually by being each other's toilet, and performing various related activities.
She squats over his face and feeds him her shit. He loves being her human toilet and watches her brown treasure slide out then feels it fill his waiting and wanting mouth. When she's finished he licks her shitty hole clean and they begin sharing, smearing and playing together and enjoy the pleasures of a truely dedicated "Scat Couple".
