You catch your step-sister going through your bedside drawer and when she begs you not to tell your parents, you realise this is your chance to have some fun with her! You tell her that you’ll only keep her secret if she does everything you say, and then inform her that she’s going to get dressed up in sexy lingerie and edge herself in front of you, as punishment for going through your private stuff. She’s horrified and says how can you even think of her in that way, she’s your step sister! But you tell her there’s nothing else you want her to do, so eventually she agrees. She shows you the underwear she has on already and you say it’s not sexy enough, and make her undress in front of you and put on a sexy black set with stockings and heels! You then tell her to get onto the bed and pass her a ball-gag, telling her it will help keep her quiet so your parents don’t hear. She complains and asks if she can’t just cum for you, as edging for so long is going to be really hard without cumming, but you tell her no, this is a punishment! She grumpily puts the ball gag in and starts edging herself with a vibrator, squriming and drooling all over the bed as she gets more and more desperate. Finally you tell her that’s enough and she begs you again to be allowed to cum, but you say no!
