The two hours and more

Bianca was humming as she opened the door to her room after taking a warm shower and nice leisurely lunch at the school cafeteria. Due to her gregarious nature and stunning looks, she had already made quite a few friends and took the time to go grab coffee with them.

By the time Bianca was back in the dorm, it had been more than three hours. She found poor Amy utterly defeated on her bed, sleek with sweat twitching and writhing every few moments, but falling still again, resigning to the lack of stimulation needed to go over the edge.

"Well, Boy-chest is almost two hours now," grinned Bianca, "Do you still say no?"

Amy shook her head hard, the hardest she had ever shaken it in her life.

"No, as in you want another two hours? I want to hear you say it."

Amy's jaws shuddered as the gag was removed from her mouth.

"Please no more...I'll do anything just make it stop." sobbed Amy.

"Alright but I told you this will be much worse than what I offered earlier."
