Go for it!

You pause, poised over her, the anticipation of feeling her warm, wet embrace growing by the second. You break the kiss for a moment to ask "How far do you want to go?"

"Well, the fact that I'm naked with you, in this position, and I haven't beaten you to a pulp should be pretty clear. But I really appreciate you asking, there's nothing sexier than full consent,"Olivia replies. Do you mind if we use a condom though? After all, it is the first date"

"Won't be a moment" you reply. "You just lay here and feel the waves on your body". Olivia sighs as you get up off her. You sprint to your bag, which is luckily not too far away, and glance back at Olivia. You realise again just how gorgeous she is. The sunlight glints off the roundness of her breasts, flattened slightly against her chest, her hips sinking lightly into the ripples of the sand, and her hair, wild from the surf. In a moment you're back by her, she's closed her eyes and has a slight smile on her beautiful lips. You don't hesitate to announce that you're back with a deep kiss.

Olivia wriggles back underneath you and reaches for the packet in your hands. Her hands are warm as she rolls the condom down the length of you, an excited smile on her face. The moment is only spoiled by a larger wave that washes over her face, but she emerges spluttering and laughing and it's back to business.

Now you are poised over her again, she wants you, and you want her. "Ready?" you ask. Her response is another deep kiss, and her hands grasping your hips, pulling the tip of your erection down against her labia. That's all the further encouragement you needed and you bear downwards. "Ouch!" You both yelp.

This is not the smooth, warm sensation you'd anticipated.

Quickly you realise that even the tiniest amount of sand makes for a very unpleasant experience.

Olivia winces. "Hmm, maybe we should find somewhere a little less sandy" she suggests. You agree. This is not quite as romantic as you'd hoped it would be. Just then, another wave crashes over you, putting a wet damper on the mood. You help her up, and you walk back to your things hand in hand.
