Genos asks Saitama to teach him how to kiss after he fails to react when a civilian kisses him. Neither could have guessed how the innocent lesson would effect them both. GenosxSaitama. Rated M for later chapters.

Genos isn't exactly a horndog, but all that changes a few weeks after moving in with Saitama. He finds himself struggling whilst living with the man he's becoming addicted to. Also, Saitama doesn't understand why Genos keeps getting all warm and steamy.
