Edging

With 5 minutes left on the clock, your Mistress doesn't waste time. "On your knees, leg spread and hand behind your head." As you take the position, she kneels besides you and put one hand on your nipple and the other on your pussy. She rubs your nipple between her soft fingers while her other finger penetrates your dripping folds with ease. You feel her warm breath tickling your ear as she whispers to you.

"If you cum you lose sweetie. So make sure to hold back. If you feel yourself too close, you can always beg me to stop." She concludes with a gentle nibble on your lobe. She increases the pace of her finger in your pussy and pinch your nipple softly, rolling it between her fingers. You pant in arousal, trying to resist the onslaught of feeling. This is made even harder when you feel her licking your ear and whisper in it. "Does it feel good? Do you hear the lewd sounds my fingers make when they go in and out of you? It's so sexy. You're drenching my hand now, look." She removes her finger from your pussy and **** a couple of fingers in your mouth, making you taste yourself on them. You suck on her fingers without thinking, breathing fast as you use the break to **** your impeding orgasm back.

But before you manage to calm down, she inserts her finger back in your pussy, two this time and resume finger fucking you with dexterity. It's the first time you feel something as good, it's like she knows your body better than yourself. As her fingers go in and out quickly, she manages to use her palm to rub your clit.

You look towards the clock and see that 4 minutes are still remaining and you don't know if you can resist that long.
