If one is fun then two are double. Nikki Darling and Mattie Borders are a perfect example of that philosophy in action. Nikki gets turned into a double-sided fuck-toy for us to use, and when we have fucked and vibrated her until she is completely cum-drunk we hang Mattie between her legs to clean up the mess we ve left. When she finishes the job we reward her with a face fuck of her own.
