Tasted My Wife

Last night my wife and I both had to work late. When we got home we ate, she took a quick shower and we went to bed. I went down on her as I usually do before we fuck. I really like eating pussy and I usually go for about 3 or 4 of her shaking orgasms. Towards the end I tasted something strange. She and I hadn't had sex in two days but it was semen. I was tasting a mans cum. The light from the television was on and I moved back and saw a small spot of white leaking out of my wifes pussy.

I concentrated on her clit and gave her one more orgasm, and then took a lick of her hole again, and got the white on my tongue. Then my tongue in her mouth kissing her. She was kissing back and then got more subdued. I think she tasted the cum. I fucked her and spilled my cum inside her pussy. She was less responsive during the fuck saying that she'd had too many orgasms and for me to "just finish".

I haven't said anything and didn't say anything as she announced leaving that she would be late again from work. I'm ashamed first that my wife is fucking around, ashamed that I actually ate another mans cum, and mad at her for what she is doing, and yet I want so much to grab her and eat her the minute she comes home not letting her have time to shower and clean what she can out of her pussy. That way she will have to know that I am aware. I hope to catch her with a full pussy and then put a big batch on my tongue and kiss her sharing it. As I go back down on her filled c**t I just want to ask her: "Whose is it?"
