My first impression of this was that it’d be a fun femdom cartoon to share. It had a nice light flowy energy. Then I looked a bit closer and realized it’s actually pretty intense. Heavy bondage and cuckolding wrapped in a deceptive presentation. I love the contrast between the style and the hot but serious scenario.
I found this on an old tumblr. I can’t find a direct attribution, but from the style I’d guess it’s by M Pluume.
