Not sure if this is what you wanted. Did you bring up the subject of you being cuckold or her being a hotwife? If so what you talked about has probably happen. It is perfectly normal, especially your first time cuckold/hotwife experience, for you to be nervous/anxious. However, I bet your excitement, waiting at home for her to get back home and provide you the details, far outweighs any nerves/uncertainty.
Her details like: how did she liked being fucked by another cock, seeing her in those purple panties and bar, how did he fucked her, how many orgasms' did she have, how big was was his cock, did he cum inside you (can I have sloppy seconds,) etc. All these details will make your cock rock hard for hours and you will fuck her brains out, maybe it will be the chance to have sloppy seconds. Also, I think your first conversations about her adventure should begin with her not with her lover/bull.
