My wife has never liked cum in her mouth. She came home last week with flavored condoms. After kids got in the bus, she put one on me and gave me a blowjob. Honestly, there was very little sensation through the rubber. But I was able to cum while in her mouth. And she didn't have to taste cum.
Last night she wanted to do it again, and I was more than happy to oblige. I stood next to the bed and fucked her mouth. When I asked if she wanted me to cum in her mouth, she said mmm hmm. That's one of the best sounds when my clock is in her mouth. Then she said I should cum in her moms mouth. Turned me on, so I grabbed the back of her head and she started stoking while sucking. I moaned my mother in laws name a few times, and filled that rubber with my cum.
Now I'm thinking of who else she'll suggest.
