Voom 4! – Ass to Mouth, Perfect Seal, direct-to-stomach feeding, causing panic. In Voom 4, due to the thickness and stickiness of my excrement, I let him sit with his mouth and stomach full of it while keeping him erect, eventually causing him to ejaculate as more and more clumps of feces fell onto his pumping hand. After he ejaculated, I left him sitting like that, laughing at him as he started to retch and vomit as his arousal and desire to be my human toilet subsided. Voom 4! – it’s hot, it’s sexy, it’s cruel, it’s horrifying, it’s the most humiliating type of human toilet slavery.
