Finish inside her body.

"Inside," you whisper back, staring straight back into her eyes.

Her face flushes even more red as she wraps her arms around your shoulders. "Oh yes... as long as Sen-nu is okay with it."

Your ear is still being nibbled, but she finally stops and presses her soft cheek against the side of your face. "You may fill up my body if you wish."

"Mmm." Mela licks her lips and takes you inside again. She shivers as she begins gyrating her hips so sensually against your groin. It isn't long before you feel yourself racing towards the finish line. It's been a wild ride, but your balls are eager to burst, and there's only so much one man can do it keep the flood gates closed. Your body grows hot, and you feel short of breath. All of the stimulation is overwhelming. You have two naked, canine-like girls with dark skin, wearing nothing at all, in a half-filled bathtub taking you together.

"Cum~!" she begs. Mela presses her forehead against yours as she bucks.

"Yes... Please cum," comes the shaky voice of Sen-nu behind. Though her emotions are usually stoic, you can tell without looking that she's completely flustered.

That's more than enough to push you over the edge. Your hands squeeze Mela tight, and you take a deep inhale as the sensation comes. You clench your teeth and groan, and you look up to see Mela respond with an eager smile. It's intense. First, you feel a flood burst through your shaft, then many more powerful pulses come after, filling the girl's body up with your fluid. She continues to move her hips, pumping every last drop from your body. You press your lips up against her collarbone and kiss her skin passionately as you're brought through an orgasm of your own. The sensation of being filled up--it's something that Sen-nu is feeling as well. She holds you tight, and cuddles up against your neck.

When you're finally done, Mela pulls away. The water is getting deeper, and just in time. She looks to you affectionately before leaning back against the tub and tipping her chin up to stare at the ceiling.

Sen-nu slides her paws up and down your chest. "And now... we can wash up," she whispers.

Mela giggles and slides a wet hand down her chest. "You are correct. That is rather efficient."

"I will make sure you are clean, Kyle."

"Me as well."

After washing down your body, and doing their own as well, even if there is hardly any room to budge within the tub--they don't see to be bothered by that--all three of you get out and begin to towel off and prepare for a much-deserved night's sleep. The twins begin getting dressed, but the outfit is new to Mela. She decides it's time to let go of the body and return it to its rightful owner.

Sen-nu is free. Both bodies put themselves together while the ghostly Mela floats beside you.

The elf clears her throat. "Ah. Mr. Warren?"

"What is it?" you ask as you tug up your pants.

"... Thank you. Thank you so much! What a relief!" She throws her spectral arms around your neck. It's as cold as ice, and after a hot bath, you can't help but shout in surprise.

"Cold!"

"S-Sorry." She floats back and fiddles with her fingers. "This is all so embarrassing. But you helped clear my mind. I feel like I could ascend to the afterlife, my soul finally free. But not yet! You will truly let me stay within these walls, yes?"

"Of course. You help us with our research and we'll help you too."

Sen-nu walks up to you and catches you by surprise with a warm, cuddly hug. You look back to see her tail wagging. But then she pulls away--blushing. "This was a private matter. You better not brag to anybody about this."

"Oh no. If everybody found out, I would die!" Mela says.

"... You're already dead," you reply.
