Looks like Xhamster ate my last comment but what I love the most about this is that it would have been such an intense sexual experience that nothing else would come close to what she felt in those moments. It is now imprinted on her brain that her most intense cumming requires a mans cock in her mouth. A lovely next step would be to have him cum in her mouth at the same time she cums.
Yummy! I'll often ejaculate when I'm getting face-fucked & the stud cums either in my mouth or on my face. The impact of the jizz makes me climax, albeit not as intensely as when I'm butt-fucked.
