Son, ever since our last... encounter... I've noticed that your 'activities' haven't stopped. In fact, you've been watching even more mom/son porn! Maybe I shouldn't have shown you my big tits... but the truth is, it really turned me on. I can't stop thinking about it. If you promise you won't tell anyone, I'll let you see them again. But this time, Mommy wants to watch you touch yourself. Take out that hard cock and start stroking it for Mommy. Show me how much you love my huge tits by blowing a big load for them. But remember... it's our secret.
