Makoto Niijima from Persona 5 in her swimwear ( Image ) sucking hungrily on a large cock (maybe this guy's - Image ) at the beach. Your choice of angle; but I'd love her feet to be visible. If she's barefoot, it'd be cool if you showed her sandals nearby (as if she took them off to get comfortable) - or she can still be in them. Artist's choice! :)
Title: The Wife Finds Out (NaruHina)
A Hinata Hyuuga version of this reference: Image
Naruto on the right with the tiny dick, Raikage Ay on the left with the huge black cock.
Make Naruto's dick even smaller than the reference and have a premature ejaculation freshly discharged from the tip of it.
Hinata should have a similar expression to the girl in the reference.
