A Steamy Bath. [WM]

Athen swiftly went into the bathroom and shut the door. She started the tap to the bath before undressing. Once she got to her panties she gingerly removed them, planning on having some fun. She grabbed her phone and slowly stepped into the bath as it continued to fill. Her cock was already begging to rise and she hadn't even done or seen anything arousing yet! The idea of what she was about to do got her going, ready for action.

The bathroom began to get steamy as the tap deposited hot water into Athen's bath. It was hotter than it probably should be, but that only enhanced to mood. Luckily, their bath was large enough to easily fit Athen. It could probably fit two people comfortably. Perfect size to have some fun with her tiny sister, her unwilling sex toy~

As the bath slowly filled she opened her favorite erotica "Shrunken Women & How To Have Fun With Them!" and began to read. She couldn't even get a chapter in before her dick was painfully erect and throbbing. By that time the bath was nearly full anyway, time for the main event! She laid her phone aside and looked eagerly down at her throbbing shaft. The thought of Zorin being trapped within was so arousing, she couldn't get over it. Athen placed her hand on her length and gingerly stroked. "Mmnhmph~" She moaned. She was really pent-up and horny... Turns out that keeping a tiny person in your balls all day can give you blue balls.

Athen felt her balls wobble in protest. Seems her tiny "passenger" didn't like where this was going. Athen believed Zorin didn't want to admit that she was enjoying this, but she guessed Zorin was enjoying this as much as Athen was. Her stroking slowly got faster and faster. She could tell that she had produced a lot of cum throughout the day, especially with the occasional struggle of a specific tiny person causing her pleasure randomly. Her balls were full. But she knew that her balls were somehow getting filling even more with her stroking. There was no way she could go on like this for long...

This was one of her greatest fantasies! How could she not be ready to blow her load so easily? Plus, the atmosphere, the warm water, the perfect erotica prelude, Zorin's **** resistance within her testicle, and her going the whole day without cumming. It was all stacked up against her desire to drag this out and enjoy it. Orgasm quickly rose as her stroking only got faster the more pleasure she felt. She was gonna cum! "I-I'm cumming!~" She moaned into the air relishing the pleasure she felt.
