It's not really gross as, well, that's kinda how most of us are even here. We humans are birthed from the wide hips of a woman and nursed upon her ample breasts...
Of course, but your own biological sister rubbing your breast milk on her face? Is that an Armenian thing? (or whatever nationality Maritsa is)
Now I want a hot "brother" to rub his semen on my face. It's for my skin complexion I swear!
