You're my stepson and I've caught you watching gay and bi porn! Don't worry, though. I'm not mad. In fact, I'm intrigued... so intrigued that I've decided to help you out. If you want to suck some cocks you're going to need training. Luckily your stepmom has a big, fat strap-on cock and is more than willing to teach you to be a good little cock sucker. I start by showing you how to lick it from the base to the tip and back down again. Then I make you open your mouth and I start guiding myself inside. Slow at first, but I just love watching your lips stretching wide over my girth. Looks like cock sucking runs in the family. Your dad likes to suck my dick, too. But he really loves it up the ass. That'll be your next training session. For now I'm just going to show you how to keep that mouth wide open, and how to use that tongue to really get a man going. I tell you to stroke your cock while you suck me off. If you do a good job I'll let you cum. In fact, that's going to be the new house rule... you're not allowed to cum without my cock in your mouth. Soon you'll be so well-trained you'll be able to get off just from sucking. You're almost ready to burst, so I give you a countdown and let you nut all in your hand. I've got a little surprise for you -my strap-on squirts! I gush cum into my hand, and from there I give you the next lesson in being StepMommy's good little cocksucker -how to eat cum! I make you lick every drop off cum from your hand. Not bad for a first try. I think after a few sessions I'll be ready to hook you up on your first date with a dude!
