You catch step-mom in a lie as she tries to sneak out of the house late at night dressed like a slut and she admits she was trying to cheat on step-dad. What the fuck, why? You thought everything was good between them? She assures you it is, but that they've recently decided to try to get pregnant again and coming off birth control has really messed with her hormones. She's suddenly finding herself horny ALL the time and your step-dad's libido just isn't what it was. step-Mom's desperate for a sexual release but letting her go out and cheat with some random guy doesn't sit right with you. Not least because you've now got leverage and you intend to use it if you need to. So you suggest she stays home and uses you for her release instead. It's hardly cheating if it's just a step-son helping his step-mom out is it? Surprisingly, she agrees and soon enough you're looking down in disbelief as your own step-mother expertly milks the cum out of your cock. Later in the week, when step-dad's late home from work, you find step-mom sexually frustrated and pent up again. This time, she wants you to actually have sex with her but there's one catch. You can't use a condom because with your parents trying to get pregnant, they're not keeping any in the house, so if step-dad found the evidence, you'd be screwed. You've got to do this raw, and you've got to promise stepmommy you can pull out on time, ok?
