When two people are actively involved in sating each other's desires, it's called sex.
But right now, Marilyn was the only one actively involved in what she was doing.
With her body half submerged inside the pool she moved up and down, her movements causing the water to ripple and splash.
Her arms were around his neck, and her heels on the surface as she moved her waist—riding her young master's manhood.
Her insides were on fire. His shaft was way too big and girthy, making it difficult for her to completely intake every inch. However, the fact his body is relaxed and he was no longer showing signs of overheating was enough proof that continuous contact and several ejaculations has helped.
Her young master couldn't take his dragon form yet or it would have been more difficult.
His eyes were barely parted as he looked at her.
She could feel the mark he had given her, burning. He was excited, and needed more.
