Not sure how you feel about NC/Semi-NC situations, but... I'll suggest something!
cub, bestiality, NC/semi-NC for kinks/theme
General idea would be...
A female otter girl between 10 and 13 years old is chased through a park or alleyway by a large dog of some sort (non-anthropomorphic) and has her skirt/panties torn off while trying to get away, at which point the dog gets other ideas and has his way with her. Bonus points for knotting and her having to gather herself up afterward and try to get home without anyone seeing her in her shameful state! Extra bonus points for her being a virgin before the encounter!
