Step-Mom-Step-Son Panty Fashion Show

When I come home from shopping for lingerie, and ask my step-son if he wants to see what I got, he can't help but be embarrassed. Seeing him blush like that just makes me all excited, so I take it a step further: I want him to see me wearing the panties, make him touch the panties; I want him to try on my panties, and cum in them, too! Try on pair after pair, modeling them and seeing how hard they make his cock before I slip them off and make him try them, too. It's so much fun that I finally suck and stroke my step-son's pantied cock until he cums all over Step-Mommy's panties!
