Walter watches porn movies and jerks off. That's his sex life. It's not the greatest, but it's all he's got. Hey! He's seventy-five years old and a widower. What the hell else is he supposed to do?
Even though he can't get as hard as he once did, he still enjoys coming. Jerking off his big boner while looking at a porn movie gets him his daily enjoyment. He does it every day and it makes him very happy. On one of those days, he gets caught by a cleaning lady who doesn't fail to notice the size of the old man's manhood.
