She wants some service.

Zoe rolls over onto her back and hands you the bottle. "Can you apply a layer, please?"

You pull yourself up on your hands, giving her an incredulous look.

"Pleeease?" she repeats, giving you a look like a puppy wanting headpats.

One hand desperately cupping your small cock, you move to get up, taking the bottle from Zoe in one hand.

Then you realize your next dilemma... If you're going to open the cap on this bottle, you might need two hands. You could use your teeth or ask Zoe to open it for you, but... You really don't think you can even apply sunscreen to her one-handed, so that might just be delaying the inevitable.

Normally applying sunblock to a girl on the beach would be a dream come true. But right now, you think you'd have preferred it if Zoe's intent was to use that bottle on you...

Fuck, what can you do?
