Probably the best story I've read, or at least half way.

[Martyn1]

This is probably a despised activity on the forums, but I'm desperate. I read a mother-son story, got about half way through, extremely hot. I have never been able to find it again. The context is a mother whose husband was a dirty cop who had a stroke. She takes care of him, while their son works to pay the bills. Things get hot when she realizes that he missed his prom/formal, having to work. She catches him masturbating, and that's as far as I got. Please help, I've searched probably a thousand stories.
