it's obvious

The bra falls off and makes a plop sound on the sand, revealing Rachel's smallish boobs. Her smile still glimmers at you, frozen perfectly. Your arms instinctively reach for her chest, as you squeeze her boobs with all your might. They feel very similar to play-doh. After playing around with her chest for a hot second, you remove her swimsuit panties by unraveling it and slipping it through her long legs.

What's now left is a naked, sandy Rachel.

You stand up and crouch and lower yourself onto Rachel's lap, pushing her legs down straightly on the ground. You turn Rachel's head to face you. You thank her for this moment with your tongue in her mouth. As your kissing intensifies, you start to take off your clothes and grope her fine body. You move your head back a bit and reposition Rachel so that she's laying on the ground, perfect position to get fucked.

You shove your dick inside Rachel, finding the juices that lay hidden within her. You can't help but keep on going, pumping in and out while the sand starts getting on your cock and in her pussy. You climax, leaving the sand sticky inside.

You jerk off a bit all over her, in her mouth, armpits, belly button, etc. Satisfied, you decide to go for round 2.

Readying up yet again, you insert your cock inside her. This time, with more determination. You grip onto her tight waist and thrusting with energy, feeling how amazing it feels to be inside a pussy again. Her pussy feels indeed quite juicy.

After about an hour of straight thrusting, you climax inside her yet again, her pussy looks like it's been sealed by Elmer's glue now.

You know you can't leave her like this, or you might be in trouble, so you drag her to the ocean and carefully wash off all your semen and such. It takes a lot of hard work but you manage to scrub it all off and you put her clothing back on again and reposition her in the closest position she was in.

You point the phone at her and resume time.

"Well uh, I'm gonna go." "Alright" You stand up and walk away, and Rachel begins to look a bit confused before groaning and orgasming, while you grin.
