"I don't see how that helps... " Andy began, but then she was flipping him over, the towel covering his midriff. As one hand rubbed a bit more lotion on his chest, the other slipped under the towel, fumbling with the button and zip. His eyes widened.
"What the fuck are you...?" He hissed, but she put her coconut scented finger to his lips and ran her palm under his bum, indicating he should lift a bit so the shorts could be slipped lower. He did as her hand bid, and brief tugs did the rest. The towel sprung up slightly in front of her as unseen pressing hardness pushed it up.
Quickly slapping some more lotion on her fingers, she swung her knee over, straddling the towel. Sandra's eyes said everything as once more she sensually massaged it on him. Then handed him the other tube. Your turn, she smiled. And from behind, eased the towel away from under her.
Andy peered at the clear tube of lube. Ooooh. Did she really need any, seeing how wet she was? She continued to rub lotion on his arms while her thighs hovered just over him, hidden by the dress. No-one nearby knew there was no longer any barrier of undies. He squeezed a cool clear worm from the tube and as casually he could run his hand under the hem, to smooth it on his naked cock and the hot folds that ached to embrace it. He started to guide it up but she gripped his shoulder in a firm 'no'.
"Let me find you." she whispered, as she continued to massage and finger his chest. To all around her, the slow wiggling of her hips was just as playful, the spread of hem hiding the fact she was also caressing his cock with her warm wet folds. Couldn't see as she leant forward to kiss him, so the burning tip at last sprung up and in, and with a lazy move she settled back, letting her smile say everything as he slowly filled her, as she satisfyingly surrounded him. The lube eased all friction, a soothing balm to both their heat but which made the joining all the more blissful.
There could be no wild, powerful pounding or writhing in so public a place so Sandra let her twat do the work, a lil twitch there, soft squeezes on his stiff shaft, and within her, Andy trembled and quivered in response. His heat burned into her like the sun on her back as slowly, almost imperceptibly, her thighs rocked over his hips. As she had massaged his hot burnt body with her hands, now her intimacies caressed his horny heat and used her own lotion to soothe him.
Raw ripples of rapture slowly brought Andy to an unhurried climax, as the sun dipped behind the high trees edging the park and long shadows started to cover their naughtiness. Most people, now done to a turn on the public barbecue, had packed up to go and complain about how burnt they were, leaving the coupled couple to finish their slow furtive fuck. Andy bit his lip, closed his eyes and gasped as Sandra gripped his girth one last lingering time and sent him over the edge. Now it was his turn to squirt some lotion, to massage her insides with a burning blissful balm. Her fingers gently clawed his chest to tell him how good that was, as her thighs trembled and bare toes curled with the effort of keeping her own orgasm obscured. And at long last, his enormously erotic erection slowly melted from her heat, softening to a stickily small size that was less embarrassing.
Savoring the last of his shrinking swelter, Sandra opened the packet of tissues and knelt up so Andy plopped out of her, and they continued to use the curtain of her dress to hide the mopping up, and ease his shorts back up. Who mattered if there were saucy splashes of dubious nature on his shorts and her dress as they packed up... that the coconut scent was tinged with a sharpness only the initiated would recognise.
After all that lotion gets everywhere.
