the idea is Julia (fe4) x Hinoka (fates) (yup), but Julia is a futa
She's grabbing Hinoka by her thighs in a full nelson position, and ramming her cock into Hinoka's dripping wet pussy, cumming and shooting into her womb, Hinoka is embarrased but also feeling real good, moaning, Julia is acting more smug and in control, either looking at Hinoka lustfully or teasing/nibbling Hinoka's ear, they don't need to be fully clothed, it's a bit of reversal of expectations which I find kinky with Julia taking control.
