Caius rose off the ground so he could really grab hold of Lea's ass before he trailed one hand down toward the middle and stroked his index lightly across that puckered hole of hers.
Lea let out a gasp in surprise and turned her head like she was trying to swivel it around completely so she could look at Caius and show him her eyebrow raised in confusion at his action.
Caius paid her no mind. He drew back the one hand that wasn't stroking the tightest hole on her body and let it snap back in a smooth action that would have been mesmerizing to watch had Lea been able to actually see it. Instead, she just felt the sharp pain of the spank delivered to her ass.
"Nghhhh!"
Facing forward again, Lea groaned and increased the intensity of a self-thrust she had been in the middle of performing.
