Weird Science of the Equine Sort with Dukeferret! (Patreon)

Doctor Duke (do not look too closely at his medical liscense) successfully triggers a slight equine transformation to his boyfriend's lewd bits, eureka! (he has no idea how he got it to work)

Duke and I have discussed an idea like this a few times before, usually delayed by my own lack of confidence regarding drawing good-looking naughty bits - but today I had a bit of extra drawing time, and Duke introduced the "mad scientist" aspect to the idea and I really liked it c:
Doubly happy with the fact that my lack of confidence for that part of the drawing was unfounded, and I'm pretty happy with how it turned out!
