Very cute and very well drawn, but in both umbreons blowjob and sylveons fuck, I feel that you could have used some emphasis, like their cocks are pretty big but Umb. Took Syl.'s fat cock in silence with not the slightest struggle, and Syl took Umb's big dick all the way to the base with only a little moan and scarcely any reaction. Just trying to constructively criticize, your art is on point though)
I noticed something about the sylveon look at the thing in the center of his neck it shows his heart rate but in page 6 it doesn't show his heartbeat meaning the sylveon dies before he does anything with umbreon (0_0) scary at least sylveon comes back to life in the next image (kinda wondering how?)
