Also for mangas you should check the tags "delinquent" since there's a lot of stories with big bottoms and thin/shorter tops
Thank you! I've teied the deliquent tag, but I've read most of those already^^'
Does anyone have any yaoi recs with small/short semes? Preferably completed! I've already read a few like Dekoboko sugary days, but would love to find more!
