~《"Satisfy Pt: 2"》~
Author: Ai2KiKuo

_" Here I come, love."

Nightmare said, slowly pulling down his underwear, revealing his now erected cock. Killer eyed the nearly 10-inch crotch, swallowing his saliva nervously. Nightmare then pulled down Killer's undergarment, his eyes darting about his whole lower region. He then slowly lifted Killer's legs, spreading them gently. Nightmare lined his crotch onto Killer's (middle[?]) Hole, slowly letting the 'popsicle' enter. Due to his ecto body being (not too much) wet, it slid in easily.

Killer winced in pain, feeling his hole being stretched with the (slightly medium) thick cock. Nightmare halted, seeing his lovers' bitter expression: eyes tightly shut and slightly twitching. He leaned into where Killer's ear should be and whispered;

_" Love, does it hurt? I will wait for you to adjust, darling."

Killer peeked one eye open, seeing his lovers' face plastered with a small grin mixed with concern. Tho, to help him relax more and to adjust quicker, he whispered acclaims to support. A few seconds passed, and Nightmare grew impatient from waiting until Killer nodded, signalling his lover that he was ready.

The first thrust sent Killer a wince of pain and then a moan of pleasure. The following thrusts stretched him more and more, moaning out his lovers name. Nightmare quickened his pace, thrusting in faster than before. Due to this, the bed was creaking. Killer was enjoying this painfully. The 'in-and-out' cycle filled him with pleasure, making his target soul swell with emotions he can not determine to understand.

With Killer's hand on Nightmare's neck, he used his free hand to grope Killer's breast, making him moan louder. It was enjoyable for both, but it was still painful for the other. Nightmare summoned two (Yes.) Tentacles. The other found its way to Killer's bottom (the b_tthole hehe-), the other muffling his mouth, commanding him to suck it. Moans were muffled by the tentacle, yet it was obvious Killer was loving it.

This continued on for a good few hours until Nightmare decided to have a different sex position. Killer was now lying down backwards, with Nightmare on his back. He retracted his crotch, huffing a little before re-entering to the 'hole' that the tentacle thrusted. A faint yelp of pain escaped from Killer's mouth, making Nightmare halt for a moment, then proceed slowly. Then, his pace quickened by the passing seconds. The free tentacle made its way to Killer's breast, groping them.

It went on until Nightmare felt that he was close to climax. Ah, the much awaited moment. He trusted in-and-out faster. A few more hours passed, and Killer felt a warm liquid spurt into his er, hole.

_" Hng-~!"

Killer hissed, feeling his spine ache in the position. Although Nightmare still continued thrusting. Seems like he wants to savour the moment more. He quickly changed their sex positions once again by teleporting Killer lying on his back. More of the 'white' liquid spurted in him, making him moan more, although the longer this continued, the more the pain came back.

His bones demanded to rest, his lower region stinging in pain. With every thrust performed, the more the pain heaved. Tears swelled in his eyes. It now started to be too painful.

_" H-honey. ."

Killer whispered in a hoarse voice, making Nightmare halt. In caution, he slowly slid out his cock as to not trigger any more pain other than what Killer is now experiencing. He huffed, slowly turning into a sob. My, it might have stinged too much.

_" Shh. . . Love. I am here. . ."

Nightmare said, trying to comfort him. A thought popped in Nightmare's head as he de-summoned his ecto body. He carried his lover towards their bathroom.

Nightmare laid Killer gently on the toilet, then opened the faucet on the side of the bathtub, which released hot water. He also opened the other faucet, which releases cold water. While waiting for the bath tub to be filled, he took a hand towel from the shelf (just beside the toilet) and knelt down to wipe the excess white liquid off of Killer's thighs with a slight pressure.

_" Does it still hurt, love?"

Nightmare asked, caressing Killer's soaked cheek.

_" A-A little, my body feels sensitive in some parts, although I am alright."

He replied, showing a small smile while trying to reach for another hand towel to clean himself. Nightmare used his tentacle to grab the hand towel from the shelf and then hand it towards Killer, who took it and started to wipe off what was needed to.

Nightmare glanced at the tub that was nearly full. Lowering the towel he held, he stood up and turned both faucets off. Dipping his hand in the water to check the temperature, it felt warm. It is just the right temperature.

He carried his lover, which made him jolt in surprise. Killer then deformed his ecto body. Placing the towel on the brim of the tub, both dipped in the warm water, quickly relaxing on as Killer sat with his back on Nightmare and with Nightmare's back against the wall.

The comfortable silence set both skeletons at ease, with the help of Nightmare's little massage on the sides of Killer's lower spine, which made him feel relaxed in his hold. This was something the couple wanted to share with each other. A time spent by them alone and them alone only.

Minutes passed, and Killer started to doze off. An obvious sign he was sleepy.

_" Stay up for a few more minutes, love."

Nightmare whispered, earning a glance from Killer, looking half-awake. The response he gave was just a simple nod. Then, Nightmare carried Killer out of the tub, dried themselves with a clean towel, and dressed in an appropriate sleeping attire. Or, just Killer wearing Nightmare's hoodie, which was too big for him, but did he care? Well, he felt comfortable in it. That was all that matters.

They flopped together on their shared bed, cuddling each other for warmth. A tentacle of Nightmare's pulled the soft sheets to cover their body's, the sound of Killer purring earned a smile from Nightmare. What an adorable sight. He kissed Killer's forehead, whispering;

_" Good night, lufu."

Nightmare, who was not expecting a reply, heard a small chuckle and a whisper from his half awake lover;

_" Good night to you too, lufu."
