We've been married for like a year now, together for five years. Sex was always vanilla but satisfying for both of us, we never complained. When she had the idea of watching some porn together i immediately agreed and thought that i should let her choose the videos she wants to see. She hesitantly clicked on a couple and i noticed that every video she clicked had a huge cock on the thumbnail. I asked her if she liked it and while horny she said yes.

I asked her to tell me more while we were fucking and she said that a cock that size could feel so different. Since then it's a habit we watch porn together and she openly fantasizes about huge cocks. I even bought her a dildo as a gift thinking it would satisfy her but it had quite the opposite effect. I can tolerate it as a fantasy but we reached the point where she's thinking and discussing with me the idea of crossing that threshold.
