She felt her pussy get wetter and wetter. She needed something to satisfy her. "Cum for me, Caitlyn." She whispered into her mouth, licking her tongue and mouth.
She realized she was hitting a sweet spot in her and smiled. She kept curling her fingers to make sure she hit it. After a minute, she felt her sister's walls tighten around her fingers as she came.
She smiled and pulled her fingers out. She brought her fingers to her mouth and licked the tip of her fingers. She moaned and pressed her fingers to Caitlyn's mouth.
