“Shh! We Have To Be Sneaky!” I Love My Dad’s New Wife

So my dad has a new wife. I came home to visit them, and she seemed... nice. Maybe she was way too friendly. She kept trying to seduce me, but I thought she was just trying to make me feel comfortable, so I ignored it until she took my pants off and gave me a hand job while my father was in the other room! There's no way I could fuck her, right? But what am I supposed to do? She even sucked my cock in the laundry room! Now that I'm about to leave, she says I can put it inside her, as long as I don't wake her husband. Fuck it. Let's do it.
