Just look at shit like https://mangadex.org/chapter/516922/11
That's just hilarious. This fool is thinking about how he has to uphold his dignity as his parents' son, while playing weird sexual harassment challenges with a home invader, tracing "dad" on the outside of her crotch with his face squished between her thighs. This is the least arousing ecchi comedy I've ever read, possibly the best drawn one, and also one of the most fun. It doesn't lose itself in absurdity and that grounding in the mundane highlights how absurd it still is.
