My wife and I were having sex the other night and were talking a little dirty and I told her I was going to come in her mouth. She moaned and sounded into it, but when it came for me to come, I could see the nervousness in her eyes, so I came on her tits. The next day she tells me that next time I should cum in her mouth. Any recommendations on what not to do? I don't want to blast away and end up gagging her or make her feel degraded or scare her away from trying different things. We're beginning to experiment in our sex life and it's been a lot of fun! Thanks!
