Straight shota
From LAH Wiki
Straight shota refers to shotakon that features a petite underdeveloped male with a female, unlike the more common yaoi version that features a shota with an older man or another shota. Straight shota often features the woman to be a plump overdeveloped female. Another popular theme features a shota with a member of his family.
While technicaly still straight shota, a shota with a loli is still labeled as lolikon. This is due to the fact that lolikon is more popular among hentai groups.
