The emerald stone causes a strange effect

Lara had been reading and studying the text for hours and it was now well after midnight. The fire was burning down and she sat in front of the fire in her large overstuffed chair staring at the red coals. She was trying to decide where to head to first, there were twelve other pieces that she needed and she could not decide how to proceed.

She also realized that her nipples were rock hard, and that she was feeling very horny. She felt a slight buzzing feeling at her left breast pocket; it was sending delicious feelings straight to her clit. She realized that the testicle stone was vibrating slightly. She pulled out the stone from her pocket and saw that the stone was glowing, and lit up from inside the stone giving it a bright green glow. It was also humming or vibrating, she could feel the thrumming of in her whole body, especially in her clit, she realized.

Lara was suddenly horny, and gripping the stone in her hand, slowly began to circle her nipples through the thin night shirt she was wearing. Her nipples were very sensitive, and swelled impressively as she touched the stone to first one then the other. She pulled up her night shirt, baring her huge perfect breasts and erect nipples. She could not help but moan in pleasure as the hard, cool vibrating stone touched her long, thick nipple. She pulled and twisted one nipple while she rubbed the testicle stone against the other. She realized that she was going to climax just from stimulating her nipples and she moaned loudly as she reached orgasm, her hips bucking and her body shaking as she peaked.

She was nowhere near done and just as horny, her pussy was soaking wet and she flipped off her pajama bottoms spreading her legs wide, her puffy cunt lips opening to reveal her wet, pink twat. She slid the hand in which she gripped the stone down towards her clit, almost afraid of the intensity of sexual desire she was feeling. The stone seemed to glow brighter the closer she brought it to her clit, and as she lightly brushed it across her clit she almost buckled from the pleasure. Rubbing the stone up and down her wet cunt until her hand and the glowing green stone testicle were coated with her cunt juice she brought herself ever closer to orgasm. At last she brought the stone into contact directly with her clit, holding the humming glowing stone against her sensitive sex organ. Her head exploded in orgasm almost instantly and it was the most intense orgasm of her life. She almost passed out from the intensity of the pleasure that rolled through her cunt in waves.

Lara lost count of her orgasms, or even the passage of time. Each wave of pleasure gripped her within seconds of the other ending and she held the glowing stone against her clit, her breasts heaving as her breath came in gasps until she finally was exhausted. She lay back in the chair, sweat pouring down her naked body, her cunt tingling like she had been fucked hard, trying to catch her breath like she had just run five miles.

Lara realized that she wanted to get the other pieces of the statue now. What the whole thing together could do to a woman she wanted to see and experience first hand. As she calmed down, she looked at the clock and realized that her little solo orgy had taken almost two hours. She had been climaxing for almost an hour straight. But now she had to get back to the question at hand, where to go first. Then it hit her where she should go...
