Two Tiny Sisters Fuck?.. [WM]

After Athen had finished another shrinking potion and scribbled all that she could remember from the experience, she ended up falling asleep at her chemistry bench and time quickly passed to the next morning. Athen awoke to what she thought were tiny moans coming from the terrarium. "What the hell?.." She rubbed her blurry eyes, cleaning out Mr. Sandman's sand, and looked around groggily.

Was she just having a wet dream and was still hearing the after-effects? Oh, did she fall asleep at her bench? She looked over at her notes. Wow, she got a lot written about Noelle shirnking! Excellent, this would be very useful for the statistics of the shrinking potion and allow her to better understand how it worked and what she could do to further modify it. Plus, she would need as many details as she could get if she were to show her scientific breakthrough to the world. Oh yeah, she remembered being able to complete a couple more shrinking potions last night too. She would need more of her cum to make any more though. That was strangely a pretty good night's sleep, even though she slept at her desk.

Then she thought she could hear the moaning again. Did she leave some porn playing or something? Then she tuned in and focused on where the sound was coming from. Wait, was it coming from the terrarium? She played through the events that happened last night, slowly remembering how everything went down. The last thing she remembered was putting Noelle into the terrarium and getting to work at her bench before she fell asleep. So Noelle and Zorin probably knew that each other was small together.

But wait... moaning could only mean one thing... They wouldn't, would they? Athen went to the back of the house where the transparent wall was and looked in. There, she could clearly see her two tiny sisters roughly fucking each other. No way! Zorin was pounding Noelle as she begged for more and more, both of them moaning as loud as their tiny voices could. It was both cute and arousing at the same time. It seemed they were both a bit pent-up. Noelle probably never relived her sexual desires and Zorin hadn't been normal-sized in a couple of days. "Oh~"

Earlier, she was wondering if Noelle was a futa too. But now that she got a closer look as Zorin rearranged her insides with her large cock she could see that Noelle was a woman, pure and true, no cock to be seen. Interesting. She hadn't realized before but her own dick was hardening in her pajama bottoms at the sight of her two sisters roughly fucking. Her horny side was beginning to take over again and she didn't think it was a bad thing...
