First time eating cum from my wife

My wife had been cuckolding me for a while now and I’ve always fantasied about eating cum from her. I imagined it would only be my cum though.

The first time I ate cum from my wife she arrived home late from a girls night out and was a little. drunk.
Being late I was already in bed and she undressed and climbed in with me.
She instantly started kissing me and stroking my cock.
She then asked if I would go down on her.
I was now hard and did as she asked
She was very wet and I just thought she was just really horny and very wet but she definitely tasted different. (That night she had gone out with her gf drinking and dancing and went back to her friends place and fucked her friends hubby. This friend and her hubby were Kristy’s regular couple. The couple that originally convinced Kristy to cuckold me)
While I was eating her pussy she started to giggle and asked if I could taste anything. I looked up at her covered in her juice and his cum and she said I was actually eating Brian’s cum from her.
I stopped licking but she begged me to keep going saying she really wanted to cum again and that I’ve already tasted him and that I had said that I have always wanted to clean her pussy after it had been fucked.
So being her cuckold I did. I licked her pussy for the next 25 minutes until she came again.
