Demi grins, as she easily brings her mistress to climax, lappign up her sweet cum, before climbing up to nuzzle with her, licking her face, lightly. She arches an eyebrow at the mention of the special potions, then grins and nods, rummaging through her pouch to pull out the small vial. Knowing she like to watch she uncorks the potion and quaffs it down, letting Chess watch as the long, thick rod sprouts from between her legs. In just a few seconds, it's fully out, and quite erect; she's clearly aroused. She doesn't move to mount Chess immediately, however, instead stepping up, and grabbing her hips. "Mmm, don't want it going in dry, do you?" she asks, as she presses the cock against Chess' wet sex, sliding it against her for a moment. "Or would you rather give it a good suck, get it nice and wet?" she asks.
