Ok, my friend, NU Star posted a pic of these two girls over in another thread:
now SRSLY, I'm wondering if that girl's white string thong is covered with brown poo stains. She can't possibly wipe cleanly everytime, can she? I'm assuming that white string thong goes up her anus/rectum so it's bound to catch some pieces of brown/yellow poo after she has defecated.
Thoughts?
