Soaping her hands even more, Katie reached up and began kneading Sarina's ass cheeks, probing even further between her legs to find her upper thighs, mere inches away from her juicy cunt. Sarina responded by pushing her ass back into Katie and shifting her feet apart so Katie could get full access, but Katie had no intention of delivering a prize just yet.
Instead, and to Sarina's complete surprise, Katie smacked her on the ass, quite hard and with purpose, the wet 'thwack' echoing throughout the shower.
"Oh wow!" Sarina trilled. "Did you really just do that?"
Thwack! Katie smacked her again, loving how sharp the sound was, before shoving her fingers deep down between Sarina's cheeks and poking the tip of her pinkie into Sarina's asshole.
"Fuck...oh fuck!" Sarina moaned, pushing back against the tiles.
