Eaters and feeders mutual enjoyment
When we do an activity, we get enjoyment from the act as well as enjoyment from others around us enjoying.
So, as an eater of my wife's shit, I get part of my enjoyment from eating it but a significant amount by her telling me how much she likes and wants me eating her shit. It's very important to my complete enjoyment that she frequently tells me these things and encourages me to eat it often! So feeders, encourage your eater to eat by telling them how much you want them eating your shit!
Similarly, she gets part of her enjoyment from feeding me her shit but even more when I tell her how much I want and need to eat her shit. She really enjoys watching me eat it. So eaters, let your feeder how much you like, want, and need to eat their shit!
Of course every couple puts their own spin on these through, submissiveness, dominance, sensualness, etc. Push our partners enjoyment as eaters and feeders even higher by letting them know!
