Your older sister is at it again with the femdom teasing. Ever since she found out that it's your biggest, most-kept secret fetish, she's been domming you non-stop. You got a little curious (and horny) for valentine's day and ended up enjoying some top-tier online fem-domming. The problem is: you accidentally charged it to your mom's card!!!! While your sister is willing to cover for you, you're totally going to have to do her a favor for it. All her femdom teasing has only been verbal, but now, she wants you to watch her masturbate and jerk off to her at the same time?? That's super taboo, and you're so hesitant, but your massive erection is totally giving it away that you're insanely aroused by the idea. She instructs you to not cum until she tells you to since she controls your every orgasm, and obeying is making you even harder. Finally, she lets you cum, but the domming isn't over yet. She tells you to sneak into your mom's room and put your cum unto the crotch of one of mom's panties. Thankfully you already busted your load, cause the thought of that horribly taboo task just might make you cum twice!
