Even as Lea moaned so loudly, Caius didn't take his mouth off her nipple. He flicked his tongue across the tip all through her climax, helping her ride the wave while his face seemed to press more and more into the succulence of her boob flesh.
With one of his hands fondling the breast he was currently not sucking on, Caius extended his other hand down to grab the front of Lea's pants under the belts she had on, unfastening it so he could reach his hand in and rub against her damp pussy through the material of her underwear. His fingers stroked her erect clit and it became the focus of his touches while Lea's climactic shudders never quite ceased.
It felt to her like whenever she seemed to be coming down from the high of orgasm, his sucking on her very sensitive nipple and his touch of her even more sensitive pussy would set her off all over again.
