Cow Edging and Precum Extraction

Description: I have a new milking chair i'm excited to test on my cow..  cow is absolutely not allowed to cum today- this is meant to be an agonizingly long precum milking & extraction..  i mercilessly tease, edge, and deny my cow- keeping him as close to the edge as possible.. once i'm done with him this session, its back into his chastity cage until i'm ready to edge him again
