I hope the friend doesn't make it... and yes, get both girls... XD
@Kami_Nana In hentai, anyone and everyone can be NTR'd.... it doesn't discriminate in gender or age... does discriminate against dick size though, with very few existing where the girl chooses the smaller dick (shotas being exempt; but they are more realistic in that it shows that females can enjoy any sized dick).
But in regular manga... there aren't much NTR rather than just break ups and sh*t....
