Lay there.

After you finish exploring her skin, you lay down to join her, though not without certain difficulties due to the condition beneath your shorts. As you begin to relax, your hear her shifting around and glance over. She sits up. Her breasts are only covered by the large amount of sand that's massed over her skin. You definitely didn't expect that, but she _does_ think you aren't interested in women anyway.

"I forgot to put sunscreen on you!" she says. "I don't want you getting all burned."

She pops the top of the bottle and begins to rub the cream over the backs of your legs, and then your torso. You honestly are thankful you can't see her body from this position. Finally, she finishes at the bottoms of your feet and giggles.

"Okay. Now, turn over."

Uh oh. You wonder what you should do. Will your charade be over this quickly? You don't have time to think about it, and turn over to lay on your back, hoping the pitched tent doesn't ruin everything.

It only grows harder though, as your eyes stare intensely at the hanging, bouncing, sand-concealed pair of large breasts in front of your face as she starts caressing your body with sunscreen in-hand. Her smooth skin rolls over your stomach and past your legs, bringing intense temptation to your throbbing erection. However, she doesn't seem to notice or care, so that's a bonus.

Though, you're almost tempted to start bonking your head back against the ground from all this accidental teasing. Can you really do this for a week?!

She finally finishes, and lays back down against the sand. You turn over, squishing your cock against the ground as you uncomfortably begin to feel the sun's warmth.

You aren't sure how long you lay there for, but it does eventually become relaxing as your erection subsides.
