Finally we find marina being bound with a chest harness and then ultimately manacled about the neck. I have her get on her knees and then lean over on her belly. Her collar gets attached to a hook in the floor. This keeps her face right in the dirt as I lube her asshole up for the enema she's about to receive. Once she is well lubed the fountain syringe is inserted into her ass and the delivery of milk into her colon is started. It is warm, above body temperature. To start she's given a full one quart enema. As it is delivered I can see that she is finding it discomforting. She's moving her hands, open - closed. Her foot taping the floor. After a minute or so she starts to flail about, or at least tries too. She's moving her hands in urgency, but that's all that's free to move. She begins to wail with a quarter of the bag left to go. Once her bowels have all of the milk enema I pop a butt plug in her ass to make sure she's plugged. I cautioned her to let me know when she couldn't hold it any longer and then slammed the hitachi onto her cunt as she screamed out. She didn't stop making noise for a full minute. Not until I told her to go thru all the sounds found in a barn yard as she gets vibbed off and holds back the enema that clearly is pushing out. I had to put my finger on her butt plug at one point to keep if from blowing out of her ass. The whole time she's getting vibbed she's moaning and groaning with every breath she makes. We can see her asshole clenching that plug, sucking it back and forth as I get her up off the floor to talk to her about what she is about to blow out of her colon. After she tells me what it will look like I have her squat over a large, clear container and have her ask permission to release it. When she blows the plug out of her ass a wad of milk follows it. Then she's got a faucet running out of her ass as she fills the container with milk & *****. When she's done I have her get up, turn around and tell you, the viewer, to come in really close and look at her poo. Then I had her tell me about all the particles that were in the milk. Afterwards, we repeated the process all over again.
