Emilia x Echidna. Futa NTR (Patreon)

Echidna felt very jealous of Emilia! Echidna likes Subaru in a kind of twisted way, but unfortunately for her Subaru only likes Emilia. And because of that, Echidna decided to take revenge on Emilia in the way of banging her! Obviously, she wanted to show her beloved Subaru the greatness of NTR! =￣ω￣=
