Kotarou Explodes (Messy) (Patreon)

Reward for Maki

(Who paid extra for the coloring, and I had a little extra time this week)

So we have Risa and her blue-haired doggy, who are both unsuccessful in holding back their urges to release into their diapers. Kotarou is giving Risa a faceful of explosive doggybutt, which both can deny that they love every squishy second of it.
