My son has been naughty, he's always got a massive erection around the house in front of me, the toilet door is always locked as he's constantly masturbating. I confront him after I was at work all day after realising he had left cum in my underwear, which the led to finding out that when I woke up the other morning my bedroom door was ajar and there was cum leaking out of me. If he wants to fuck me he is going to do it and look me in the eye, and stop being sneaky about it...time to teach him a lesson.
