With a firm hand

"So you like that, huh?" You're grunting in delight as you slip your cock back out of Jessica's sweet mouth for a moment, watching as sticky threads of spittle and precum form and then break between her lips and the head of your penis - falling away to splatter on top of her beautiful breasts. Then you push right back inside again, before she's had the chance to reply or even recovered her breath, and enjoy the look of lust becoming more apparant among the other feelings written upon her flustered face.

"Nuh...!" Jessica gasps as you pull away once again, this time hurrying up to catch her breath before you push back inside, and finally dare to look up to your eyes again as you tug at her tousled long hair. "Why...?" She moans, still breathless from your vigorous use of her sweet lips, and you allow her another few moments of freedom to speak her mind at least. "Y-you could've just... tried and be nice with me...!"

"And risked you to keep saying no...?" You just smile back at her, suddenly pushing her down on all fours in the sand, and making her gasp in surprise as you reach for her behind and give it a sharp slap. "We don't know how long we'll be stuck on this island, and I just wanna make sure we've had as much fun as we can before we end up dying from starvation...!"
"Ow, fuck...!" She keeps gasping and tries to roll away as you spank her again, but instead ends up flat on her front while you quickly get on top of her and straddle her waist. Then you start alternating between spanking and kneading that sweet ass, until she's moaning with every stroke of your palm.

"See, you're just needing to be tamed!" You flash her a grin over your shoulder, though you're surprised yourself at how well it's actually working out. She sends you a heated glare in return however, but still ends up spreading her legs for you while your hand slips down between them.

"Uhnnn, fuck...!" She repeats, and then again as you lean down and lend your tongue to the mix of sensations coursing through her body. Her voice reaches a pitch then as you spread her buttocks with your hands, licking your way up across that sensitive stretch of skin between her pussy and back door, before teasing driectly at the puckered ring that is her sphincter.Still she's barely making any objections any more, but simply lies back and takes it while you alternate your attention between her two holes and also resume your firm handling of her bottom.
