Is there rape in it?

ML forces MC to give him a blowjob againt MC's will. That much I'm sure of. Whether the full thing happened or not, my memory is a bot fuzzy. MC was also the victim of another incident of non consensual sexual activities by someone other than ML

Nothing.but somehow the ml sometimes in the early chpters forced the uke to have sex with him but he teach him that thats a rape if the other people doesn’t want to do it.he teach him to have sex to other people with consent.
