Why can you not count the MC as a MILF? BTW, colloquially ... a cougar/milf are the almost the same thing...... As the definition says [Sex act with an older woman who appears to be within the age range of 30-50 (doesn't need to be a parent).] ..... then as you said above "Myriam herself is a MILF and therefore ...MILF tag..." doesn't work, can't count the MC as the milf, and if you do the following applies from what I see in the VN:
As all the sex act in the VN Myriam is WITH OLDER woman, Myriam herself is always THE OLDER woman with a younger woman...... so COUGAR more then MILF tag???? Which there are other VN now that I think about it, that need a COUGAR TAG more then a MILF tag..... Especially when the MC is a female....
