It wasn't long before Samantha moved down from Lisa's back, her hands landing on Lisa's butt. It was a nice, well above-average ass. Nice enough for Lisa to get hooted at occasionally when she walked past a group of men. It wasn't anything amazing, not like the monstrously curvy meat Samatha sported on her own backside.

Lisa meanwhile had been reduced to a moaning mess, her 'perfectly competent' maid's ass massage sending wave after wave of pure pleasure through her. As Samantha began to move her hands lower, Lisa spoke up.

"Make me cum, maid-" she ordered breathlessly.
