Beautiful, great body (she still has her original body back after having twins too) sexually open but broke it off because she was embarrassed that she shits.
She probably also cut you off, because your actions showed you didn't care about her and what she was feeling and experiencing.
I had my high school girlfriend shit all over me during anal. Sex was feeling very good for her. It was our first time doing anal. Then out of nowhere she pulls off my dick and shit falls out of her ass and my dick was already covered at that point. She runs to her bathroom. She was in the bathroom for around 5 minutes before she opened the door to let me in. She was crying and embarrassed. I started the shower and we took a shower together. Many times I told her it was okay. In the middle of the shower I was hugging her from behind, I had her lean over a bit and I put my dick back in her butt. In a minute I was filling her rectum with my big load. She was moaning like crazy. After we showered and I cummed we laid in her bed and fell asleep naked.
That's one reason I recommend shaving your pubes if you do anal! If I would had been hairy it would had been more messy. I've always shaved. Also now married to her
