Write a story about a girl named NAME_1 and her boyfriend NAME_2. NAME_1 suggest to do scat play. NAME_1 shits directly on NAME_2's erect penis. He penetrates her, using her own shit as lube. While he is penetrating her, she uses her shit covered feet and rubs them all over his chest. The stink is extreme. Suddenly NAME_2 also shits a lot on her. They are covered in their own shit now, rubbing their bodies against each other. NAME_1 penetrates NAME_2 with her foot. He penetrates her with his penis. Mega orgasm.
