She couldn't control it

Erin has only begun the challenge, but she knew she had already lost. She had tried all the tricks she knew to calm her spirit. She couldn't say she had any real experience trying to control her lust before. She wasn't a virgin, but she didn't have many sexual experiences before getting hooked on the simulation. Her hands were already out of control. Her left one was already moving underneath her bra to explore her new cleavage and what she found there was astounding. It didn't take long for her fingers to find her nipples which were larger than before and way more sensitive. Her fingers began to play with her engorged nipples teasing pinching. Erin could feel the intense pleasure coursing through her body.

Erin could feel her pussy gushing her juice with all this pleasure coursing in her. Back, in the real world, something like that would have been impossible, but in this world, everything sexual was more intense and more pleasurable. While her left hand was busy with her breasts, the other one was tugging on her panties. Erin didn't have the courage to plunge it inside yet. She was still fighting the lust, but she was losing the battle. As she tugged on her panties, Erin could feel the fabric on her sensitive clitoris. Louder moans were escaping her gorgeous mouth as her tongued went out. Making the classic ahegao face.

Without thinking about it, Erin moved back on her knees and let her upper body topples over. Her breasts were pressing against the cold ground and her hand reached between her thighs from underneath. Her inexperienced finger easily finds her sensitive spot. All Erin could do at that moment, is live for pleasure and for lust. Her fingers deftly penetrated her pink sex. It was slow and a bit sensual at first, but the hunger was way too strong and it all became very animalistic. The pressure of her breasts on the ground, her finger pumping in and out of her eager pussy was all Erin needed. It didn't take long for an orgasm to explode in her being. For a mere moment, it was the best thing that ever happen to Erin as long guttural yells were heard. Her pussy discharged a lot juice behind her leaving pools on the ground.

After a while, Erin's breathing came to a normal state and her intelligence that had flown away because of the curse came back too. Erin felt shame climbing to her cheeks. She realized that she had masturbated like a cheap whore in front of a complete stranger and much more than this her pride was hurt, she had lost the bet.

The strange woman who now was an astounding young beauty was standing next to Erin. Her hands were on her gorgeous breasts and she was smiling. "Now my dear will honor your side of the bargain?" Asked the beauty giving her a cup filled with the fountain water. "Remember, if you don't honor your word this world will punish you for it and even me I cannot anticipate how."
