Otoko no Ko wa Miraretai

Days of sweat and lovejuice with a (crossdressed) boy who's "absolutely more kawaii than any girl" ~ It was a traffic accident that changed everything. We're dating, said the protagonist, a white lie that inspired their relationship of earnest, mutual stimulation. Time passed. The pretty, girlish-looking shonen shared various "interests". An interest in wearing girls clothes, for example. An interest in teasing his anus open. Using toys on both holes. Time and place didn't matter, they tried it all.
