Far from a "play date" at bondage, Brice now found himself a helpless captive and new found pet of his sex buddy Derek. Inside the suit, he held in his mouth a thick gag through which the tube passed, allowing only liquids to pass into his mouth and gut. And now Derek has started to attach a funnel to the tunnel and using Brice as his personal urinal as well as pet.
He could make no sounds but grunts. His begging to be let out sounded like "ugh ugh" instead of "let me go". Brice's dick is held in a ultra tiny chastity cage, and he has a catheter in his bladder that Derek closes off with a clip. Derek is fond of keeping Brice's urine from coming out, to the point where Brice forgets every thought but the need to pee. Unknown to Brice, it is part of his "thing" training.
It started off as a fun thing to try but now everyday Brice becomes less human and more a helpless sightless soundless pet thing. It was Derek's twisted plan all along and Brice fell into the trap so easily because of his loyal, trusting nature. Exactly what you want in a good pet.
