Take Yin in the bath.

She's so submissive. Delphi was right.

You stand up and she watches you intently, and you then slide your hands over her ass, up her sides, and firmly grasp her body as you move your pelvis towards her awaiting pussy. Not wanting to wait any longer, you thrust your cock deep inside her. Yin moans out loud immediately, and her tail begins to flail as it briefly smacks against your chest before moving left and right. You gyrate your hips, sliding your shaft in and out of the devil maid's quivering body. It's hotter than anything you've felt before, almost like putting your cock in an oven. If it were any hotter, it would actually hurt, but her incredibly warm and tight body feels amazing, and it seems like the feeling is mutual. By her sounds and the flustered look on her face, she's already completely lost to the pleasure. Each thrust inside of her sends a shudder down her body.

"Mmm... Y-Yes, right there, Master~!"

Her euphoric voice encourages you to thrust harder. Her body's pushed forward and back--tits pressed against the floor. As you continue, however, you come up with an idea. You snatch the tail whipping around in front of your eyes, and she immediately lets out a gasp.

"Aah! That's my--" Yin's unable to say anything else.

You begin sliding your hand up the shaft of the tail up to the spade-like head, and with your thumb, you massage the flat end while continuing to thrust inside of her. She tries to speak, but all that comes out is mumbling gibberish. You're completely shutting down her brain from all of this pleasure.

"Cu... C-Cu... I'm... Aaah~!" Her hands grasp at the tiles in an attempt to find something to hold onto as her entire body tenses up. She lets out a **** moan of pure euphoria as her body orgasms, but you don't stop. You continue slamming her up against the side of the pool.

Even her heavy breathing becomes loud. You can only hope nobody is right outside of the door.

"F-Flip... I..." she gasps.

You look to her, and she gazes back at you as if trying to say something. Finally, you remove your cock, grab her body with both hands, and flip her around. She pulls out of the bath and lays back against the floor by the edge--naked figure glistening before you. She pants hard and returns your gaze before it trails down your body to stop at your cock. You're definitely not finished yet.

You crawl onto her, and once again slide between her legs. She gasps out as you take her again, this time in a different position. You kiss down her burning hot neck, and then enjoy the soft tissue of her chest against your mouth. The thrusting of your hips bounces her body forward and back, and she looks up to you with a dizzied smile.

"Master..." she whispers. Her eyes then roll back as they flutter shut. "Yes~!"

Even the strongest man in the world couldn't hold an orgasm much longer with a girl like this. You feel your heart beat quickly--your balls tighten. It isn't going to be much longer before you burst inside her.

"I'm gonna try something, Yin," you whisper.

"Try anything, Master..."

As you pin Yin down and fuck her hard beside the bath, you decide to try something you haven't before. With that new spell of yours, you can fill someone with pleasure, and with enough mana used, you can make someone orgasm. Therefore, you wonder how it'll feel to use it when one was going to orgasm anyway. You decide not to use too much power, just in case it breaks her mind or something, but it's now or never.

Yin bites her lip. "I... I'm going to...!"

Your cock finally erupts. You tense up, and each heavy pulse sends a burst into her body. Though as you do this, you groan out, "P-Pleasure!" with your hands on her body. Some mana is used up, and then the effect hits.

Yin opens her eyes wide.

She grabs your body and squeezes hard. It's like a surge of electricity is violently shaking through her body. As she's about to naturally cum, your magic pushes her into another, and her body throbs with the pleasure of two at once. She holds you in a tight embrace as she moans loudly into your ear. You look to her face and she looks completely lost--drool coming down from her lips, and her eyes are staring upwards at the ceiling. You gradually stop thrusting, and you pull yourself out and off her body to rest beside her.

Her chest heaves up and down. A moment passes by, and she finally turns to face you.

"Master," she whispers, and wraps an arm around you to cuddle beneath your neck. "Oh... Master... Master..."

She repeats herself a few times more, slowly becoming quieter until she falls silent in your arms.

Eventually, she looks up to you. "Let's finish washing up, Master."

You smile back. "That's probably a good idea."
