Welp - it finally happened - mixed feelings

We got together when we were both 20 - married at 25 and now we are both 28. I'm an average white guy - she is an exotic, sexy Filipino girl. Sex has gone from everyday at first - to once or twice a month in the past few years. It's great, but it's been pretty routine lately. I've been into cuckold stuff forever - but always as a fantasy. We talk about it a lot and it always gets me off like nothing else. Recently, she got fed up with my mediocre at best sex and we got officially separated. But we are still friends and we are still living together for now. She has started activity dating and I - not being the jealous type of course - encouraged her to do so.

So on one of her first "nights out" we both knew sex was a possibility. She told me the guy she was meeting was insanely attractive and that this would essentially be a booty call. She was extremely horny before heading out. She got home the next day at 10am with a "glow". A few hours later I started prodding for details. She was reluctant at first but then said it was simply the best sex of her life - oh - 4 times in a row. A little more pushing and I got some more details - she was thrown around - eaten out like never b4 - sucked his cock dry. She kept saying the way he moved - it just made everything feel like she had never been fucked like that b4. Everything was like never b4. Whenever she would start recalling some detail, her eyes would just roll back and she would moan a little. She said no one has ever been able to make her cum so effectively right off the bat on the first fuck like that (it took me several weeks)

I mean - I have a big dick and I thought I was pretty good when we got down to it - but hearing her it was like I was a limp dicked virgin compared to this fuck machine. It was erotic to say the least - and I've been jerking off 3-4 times a day thinking about it. However the in between times - I'm feeling a little like cuckolds brownie. Any advice?
