Tell them Mom will be home soon

"Uhh.. Look, our Mom will be home soon. If she finds me like this she'll think that you did it and you'll get into big trouble. Please untie me. We won't say anything - honest!"

"I think you're lying little lady. If your Mom was going to be home why would she have arranged for her daughter to wait in for a delivery?"

A hand grips the crotchrope just where it emerges from between your buttocks. The pressure on your genitals increases. You panic. You couldn't stand another orgasm like the one you've just endured.

"Please don't! Please stop. Don't. Please don't. Don't pull that. Don't make me cum. Please don't make me cum again."

"Well, since you ask so nicely I might just consider it. And what might you offer to help me make up my mind?"
