This wasn't this hard for me, or the couple I met on line. We advance planned to meet in a desolate area of a Forest Preserve, our back packs, and several gallons of warm water to play with, as we all brought 2 gallons each. Then our nakedness and blankets came out.
The woman in charge, gave us both males enemas at the same time by hanging the bags in a tree branch nearby, then working the white douche nozzles in and out of our ass's. We were both told made to hold our water as she walked around, then slapping our asses during our filling. She also rubbed our bellies to see how full we were, and IF our cock's got hard by brushing up against it.
Soon our bags emptied. My ass was leaking already. This lady closed the clamps on both bags, and pulled our douche nozzles from it's moorings and said it's time to expel.
Both of our asses leaning against separate trees as we let loose. When we got done our giver got hers, as she enjoyed enemas too.
Naked on the blanket, butt up in the air. We both guys enjoyed watching her reaction of her getting an enema, pleading, and expelling in the woods. This time, in front of us two.
