Back when they were younger fillies on the rock farm, Limestone and Maud Pie used to do a lot of things with each other... including exploring their bodies. Of course, they are grown mares now, and they haven't done anything naughty like that in years.

Still, Limestone likes to visit her little sister, and spend some time at her place to cool down away from the rock farm when the stress becomes unbearable.

Content: masturbation, sex toys, sisterly incest, some swearing, mentions of past masturbation as foals.

Written as part of the Summer Sin Celebration 2021 for Shrinky Frod, who wanted Limestone to let out some stress with somepony else. I hope you like it!
