The anime/manga version of an orgasmic facial expression. It's generally very sexualized and lewd, and may or may not be accompanied with heart eyes/pupils.

Ahegao is commonly used in any kind of BDSM type hentai, along with hentai that feature the "rape" fetish. However, ahegao does NOT equal rape.

The extremely exaggerated facial expressions a woman makes while being fucked silly, usually in hentai but sometimes in real porn (usually cosplay), including puffing out their lips, sticking out their toung and makeing their eyes roll around or go cross-eyed.

The faces Belle Delphine makes
Guy 1"Hey did you catch the new hentai, where that slut was fucked silly and made boner inducing ahegao faces?"
Guy 2 "Yeah, I jerked off to it at 2am last night."
Guy 1 "I started jerkin it at 2:05 and came at 2:23"
Guy 2 "that's the exact same time I ejaculated!!!"

In the world of Hentai, it is the point in which a person cums so incredibly hard that they lose all motor functions with their face. They go cross-eyed, open their mouth wide, stick their tongue out, and drool as though craving a HUGE DICK IN THEIR MOUTH. Nothing is more beautiful than an ahegao face because you know in that moment that person is achieving supreme happiness.
She achieved ahegao while masturbating in the school bathroom.

I ahegaoed her in the butthole.
I ahegao, you ahegao, he, she, me ahegao.
