A special surprise

With Eliza out of the way again you turn back towards Mistress, wondering what else she has in store for you. To your surprise, once you are facing her direction you notice she has taken off one of her gloves as she reaches for your crotch! You let out a small squeak as her fingers explore between your folds. Her index finger soon finds your clit and she smiles as she focuses on it, circling her finger around it. The gentle stimulation on the sensitive nub makes you lose your composure, leaning forward and grabbing Mistress's arm for support. She circles it several more times before trailing off, exploring some more until her finger finds your hole, which she begins prodding lightly. At this point you are practically dripping, and she slips in past her first knuckle with no resistance.

Mistress pulls her hand back, seemingly satisfied in your reaction. She has a satisfied look on her face as she sees your wetness sticking to her fingers, pulling several trails of sticky fluid as her hand retracts that last for a few inches before disappearing. She turns her hand over, looking at the extent of your wetness that she has coaxed out, before grabbing the second object from her other hand - a small, oblong stone about an inch long and about half as wide, glistening a deep red that matches your collar.

You aren't given any time to wonder what it could be used for, as Mistress reaches down once again to your cunt. She wipes the stone up and down your slit several times before pressing it into your virgin hole. To your surprise, it slips in with no resistance at all! You gasp again at the sudden intrusion. You've never put anything bigger than your finger down there before, and she just stuffed this thing up you without any problem. You feel your muscles press against it as Mistress pushes her finger inside you, forcing the object deeper inside you.

Your legs shiver as her first knuckle goes inside you. As her second knuckle reaches your entrance, you teeth grit and your eyes squeeze shut - you've never had anything this deep inside you before! By the time she sheaths her entire index finger inside you, you can feel the stone resting against your cervix. It's such a foreign sensation to feel something lodged so deeply, but it feels so good. Mistress slowly slips her finger out of you, but the stone stays lodged in place.

You regain your composure as you slowly get used to the feeling of the object buried in your pussy. Soon Mistress chimes in, "I hope you like it, Rosa. That's my special gift to you. Don't worry about it falling out, either. It will stay in place no matter what happens." You feel strangely reassured at that statement, so glad that you'll never lose this precious gift from Mistress! "Let me show you what it can do," Mistress continues. At a snap of her fingers, you feel the stone begin to vibrate. Your knees get weak and your inner walls contract against the unexpected pleasure. A heat builds up in your womb and explodes in an intense orgasm. You are left shaking and on your knees as the vibration fades, sitting on the floor to recover.
