Big Cock Addiction

My wife and I always had a good sex life. Sex once a week maybe once one the weekend, then maybe a few times when she was ovulating.
She always said it was plenty for her.
But since she started seeing her most recent bull (for 2 years now) she seems to be addicted to his cock.
Ovulating, mid-cycle, even on her period, she has this need to get him in her.
Has anyone else experienced this.
