Wow amazing,, if i have to say,, my fetish about incest, and blood-related LoL . But generally i like good artwork, good plot, cute uke and sweet seme and hot+sexy scene

i did have a time where i gobble incest stories like mad but it's more about fatherxson stories, blood related or not. as for sexy scenes... it's probably because i've read too much (still not counting the ones i've read from other sites) that i kinda got jaded on the usual ones hahaha. so when i call it hardcore, it should be really something
