You sneak into her room while she's having some private alone time and start masturbating to the glorious scene of your step-mother getting herself off, but she senses somebody watching. She's outraged and disgusted as she pulls herself together and tells you to get out. What were you thinking, put it away! But you stand your ground. You're not leaving unless she lets you fuck her. She scoffs at the idea but softens quickly. Your stepmom's always been such a pushover. So she invites you in and asks if she sucks your cock, will that get rid of you? But as your pumping it harder down her throat, she pulls back. She's not a stepmother who's going to raise a selfish lover. If you want to take, you need to give as well. She lays back and instructs you to start licking, but the build up of having been so turned on from masturbating, sucking her step-son's huge dick and now having your tongue all over her clit becomes to much to bare. She cracks and invites you in. Inside of your step-mom. But we do not talk about this ever again, you understand? This happens just this once.
