Ellie had already been so turned on ahead of time, especially from already coming once, that it wasn't going to take her much more time before she did it again. Plus, she was just a sensitive person in general. Always had been.
As they continued their romp, Elle wrapped her legs around his waist, opening herself up the slightest bit more, and arched her back off the bed to press her breasts against him. Her lips moved from his mouth to his earlobe, tugging gently, the hot, quick breaths coming from her tickling his ear, hearing her arousal as clearly as he could as she moaned for him.
When his hand slipped between them and rubbed that sensitive bud of nerves, her entire body shuddered, her nails digging into his shoulder again as she held on. And though perhaps out of pure luck, her second orgasm hit her body it seemed, at the same time Henry's was on the horizon, causing them both to fall apart for each other in quick succession. It was... incredibly sexy, to say the least. At least to her.
