Rub the lotion on Yin.

You kneel down next to her and squeeze a decently sized blob of the sunscreen onto your hand, place the bottle back down, and then rub your hands together. You're not exactly sure where to start. If she had a bikini, it would make more sense, because you'd simply apply it to her back, but what she's wearing covers that. So, you do the only thing you can think to do, which is to apply it wherever you see the bright redness of her skin.

First, you touch parts of her arms not covered by her head, and then you gently squeeze your hands around them as you glide up to her shoulders. She's hot to the touch, and not just because of the sun. It's like feeling a hot water bottle. You continue this massage by kneading into her shoulders around the bathing suit straps, and you then part her hair to the side in order to rub against the soft back of her neck. She sighs softly at your touch, so you must be doing a good job. As you continue, you suddenly feel her body shiver.

"How is this?" you ask softly.

"It's so nice," she whispers. "Thank you, Master."

The next part of her body that can be covered is right below where the bathing suit ends. It cups around her cheeks so tightly that her ass is presented in a tantalizing way. You first start at her feet, and then massage her legs, slowly moving your fingers up higher and higher over time. Though as you enter the area of her thighs, she starts to act strangely. Her body fidgets in place, and you can hear her breathing from here. Your thumbs glide up right between her legs, and the slipperiness of the lotion allows them to glide easily along the edges of where her swimsuit bottom ends, which causes her to audibly moan in pleasure. You slip your hands through and back a few times over, and then rub them gently around the bottom of her cheeks, causing them to bounce each each movement.

"M-Master~..." she mutters. Her legs start pressing tightly together. "I th-think my legs are covered. But you missed one more part. Just please don't do it for long. Just quickly please. And tell me when you're going to do it."

What is she talking about?

You inspect her for a moment before you spot her tail! It is exposed skin after all. You reach out and grab it and say, "This?"

"Aah~! I said tell me!"

"Sorry!"

"It's okay... P-Please be quick."

With some lotion still on your hands, you slide them up the tail from the bottom all the way to the tip, feeling the flesh between your fingers. You bring them up and down a few times before pinching the flat spade tip and rubbing your thumb against it curiously. The whole time, she wiggles in place with her lips pressed shut, but by the end, she can't hold in the noises anymore. A **** moan bursts from her mouth, and her hands grip the towel beneath her.

"En-Enough! Th-Thank you!" She falls limp and breaths heavily.

"I'm glad I could help." Your cock tingles.

"But you said you would do my front too," she says as her body begins to twist. She looks up at you with pleading eyes. "Right?"

"Right, yes. That's right. Turn over if you want."

The cute devil maid now lays on her back before you in nothing but a one piece swimsuit, and she's staring up at you, eager for you to rub lotion anywhere you can see a place to rub it. It's a lot more embarrassing in this position. Normally, she isn't looking directly at you. You get some more sunscreen between your hands and begin the second round regardless, moving them up the fronts of her arms up to her shoulders. She looks up to you with deep crimson spreading across her entire face as you lean over her body and slide your fingers across her neck and down her collar bone to her upper chest.

"Your hands are gentle... Master," she whispers.

You're making this really difficult, Yin.

Your hands slip into the gap in the middle of her suit and you massage the lotion around her navel--fingers moving partially beneath the material. You brush the underside of her chest before pulling your hands back, and next moving to her legs. You work your way up to her inner thighs, and just like before, you work around the bottom of her suit as you lotion up her slender red legs.

When your eyes return to her face, you can see that she's completely flushed as well as breathing heavily. Her eyes turn to yours, catching your gaze. She's burning up, and that's saying something given what she is.

"Is that good?" you ask.

She nods. Her chest heaves up and down as she takes deep inhales, and trembles slightly as she sighs. Meanwhile, you take some of the lotion for yourself and begin applying it to your body. It isn't just the girls that are in danger of sunburns after all. Though once you finish, you notice Yin is pulling herself up. She crawls off into the sand and knees next to the towel expectantly.

"Now you," she says. "Please? I want to help you too."

"I guess that's fine," you say, crawling onto your stomach. The towel is hot to touch.

"There's only a little bit left." She squirts it into her hands, though you can hardly see from this position. All you can spot from leaning your cheek on your crisscrossed arms is the side of her body through your peripheral vision.

Though, you do feel the cool lotion suddenly press into your back. Her touch is incredibly gentle. The girl's delicate fingers trail up to your shoulders, down your arms, back over your shoulders, and down to your lower back in a relaxing massage. You suddenly feel an oncoming warmth as she comes in close on your opposite side. She whispers softly, and you feel her breath tickle your ear.

"Am I touching you well, Master?" she says, and then continues her work.

After rubbing all over her body, the reactions she had, seeing such a cute girl in such a cute bathing suit, being massaged by her, as well as pressing up against the ground, you can't hold back anymore. The tingle in your cock becomes a rising erection, forcing you to shift awkwardly to make room below you--body tilting very slightly to the side.

She glides her hands up your legs, slipping a little bit too high as she grazes the bottom of your ass through the legs of your trunks. She pulls back as she puts her hands to her sides.

"S-Sorry, Master. I think I'm finished, though."

You glance up to her. "Thanks, Yin. You did well."

"Would you like to do something while we're here, Master? Perhaps play on the beach, or get something to eat."

"Uh... I think I'll stay laying here for just a few minutes."

"Okay! I'll wait here with you," she says as she positions herself kneeling directly in front of the way you're facing. You look up at her curvy, oiled-up figure, which isn't helping your condition at all.

"Actually, you can totally go play with the others. Just give me a few minutes. Honestly, I'll catch up."

She tilts her head to the side. "Is something the matter, Master?"

You sigh. "N-No... Everything is fine."

As Yin leans forward, you stare down her cleavage nestled tightly in her swimsuit. "Are you sure?" she asks.

"Yep! In fact, you're supposed to be on vacation, Yin. As your master, I command you to go have some fun. I'll be with you shortly."

"Oh. Yes, Master!" She nods and stands.

Finally, she heads off to leave you alone. You were worried for a moment that it was going to be impossible to start sheathing your sword. For the time being, Yin heads off elsewhere on the beach, giving you a chance to take a breather.
