How often does your female partner suck and then swallow your cum?

My wife had been mostly a lesbian before we met. So sucking cock was something she wasn't eager to do. But she was doing it. I fired a load in her mouth, and she spit and gagged a bit, but she didn't wash her mouth out. After we did a few threesomes with another woman, she watched the other woman suck my cock and kind of started figuring out her way. One morning we did oral on each other before getting out of bed and she ended up swallowing my load. Evidently it went well with the sticky buns she had with her coffee, and I started getting blown before breakfast more often.

Back in college, I had a gf who had the goal of blowing and swallowing at least 3 times during the week, and a few times on weekend. I went out with this girl for about a year. On top of "regular sex" - which we had often - I estimate that she swallowed at least 300 loads of my cum over that year. She was awesome. And honestly, getting a nice blowjob is just so relaxing.... When first married, I was getting a bj/swallow a few times a week from my wife (and she had been a fan of it before marriage, and from what she told me when we first dated, she enjoyed sucking cock and usually swallowing ever since her first bf in highschool.) Now, I get one maybe once a month - but its still great.
