This is too much for me and I begin to unload into her mouth. I hear her gag a little as shoot what feels like the biggest load I have ever shot. Jenn continues to keep my cock in her mouth after I have come cleaning up every drop of my jizz.
As I begin to soften in her mouth she draws her head back letting my cock fall with an audible plop. I look down at my mother in laws face and see she has a small dribble of cum running down her chin.
