My frigid teen step-daughter has come to me for help because she doesn’t satisfy her boyfriend. I am happy to help them both, it’s the least a good step-mommy can do! I am a lot more experienced in these matters after all. I take my step-daughters boyfriend in my mouth and teach her how to give a decent blowjob. I could tell he was very wound up and horny and desperate for some kinky fun that my step-daughter just couldn’t provide. She tries to take over and I slap her hand away, telling her NO... he deserves to be made to cum by a real woman. I proceed to CUCKOLD my own step-daughter, teasing her for being frigid and boring while her boyfriend was harder than ever for me and cumming all over my face. Of course I ordered her to play with her tight pink pussy while she watched us in humiliation.
