Looking for a manga that has two brothers that are completely different. The fathers/grandfather(can’t remember) dieting wish is for the oldest to stay pure or some shit. The younger of the two puts a cock cage on him so he can’t lose his virginity. So he starts to finger his ass so he won’t have blue balls it ends I think I fucking. Please help me find this I have been looking for a while.
Don’t like the ml he’s nasty
