Undertale Love Stories

Crossmare| Joke pt4

Nightmare woke up in heat. He had learned all about this from Cross and whenever he actually went into heat, Cross would help him. Sure, he'd get a bit of teasing, but it just made his heat worse and better at the same time. Now though... He was alone.

He pouted at this, slowly sitting up in his bed. When he didn't realize he was going into heat, he just grabbed some food and held up in his room. He was going to attempt to do that now as well. It was the best he got since he didn't really know what to do alone.

The sound of crinkling paper grabbed the King's attention, making him look down. There was paper, a note most likely, laying on his chest. He sneered some as he grabbed it. He thought that it was one of his lazy Generals. However, the sneer quickly fell into a soft smile as he recognized the handwriting!

Nightmare, I know all about your stupid bet, you told me remember~? Nightmare winced at that. But you also told me you couldn't live without me. I see you really can't~ Without me, all those idiots would be trying to attack you. The King winced again, his smile falling. But I have missed you~ I see you like the scarf~ He grabbed the scarf, putting it to his face. Cross's scent made him groan softly, his heat peaking. I know you'll be entering your heat soon~ I want you to follow my instructions the best you can~ Afterall, I can't just leave you suffering~

The King tilted his head some as he read Cross's instructions once, twice and then a third time. After having memorized it, he set the paper down and went to his door, locking it as he was told. He then stripped naked, leaving only Cross's scarf on. His already flushed face darkened.

"W-Why couldn't he stay and he-help..." He whined some, pouting as he laid him on top of his bedsheets.

He pouted more as he summoned his male body. His lavender echo-body pulsed with need, his cock already leaking pre-cum. This made him bury his head into Cross's scarf some. The sent made his body pulse more, his cock twitching in excitement.

"Cross..." He whined, closing his eyes tightly. He knew he was told to do it, but he didn't want to! He wanted Cross to help him!

Biting his lip, he shyly grabbed onto his cock. He shuddered a little at the feeling, whimpering softly. Taking a deep breath, he began to pump himself like how Cross had him do it. It felt weird, but it also felt good.

It wasn't long before he began to moan and groan happily. He kept the white scarf pressed against his nose, breathing in his lovely Cross's scent.

"C-Cross~" He whined out, cumming in his hand. He panted some, but his body didn't feel better. It actually felt worse, hotter and more aggravated.

He whined, bucking his hips into his hand, trying to pleasure himself enough to go to sleep. The pleasure built up slower this time, but again his body was still too hot to help him sleep. All he was doing, was making a mess of himself. He knew that, except he couldn't stop bucking his hips or moving his hand up and down. His mind was growing blank with only the orders that were given to him to help guide him.

"S-Senpai~!" He had cried out, cumming for a third time. This time, he was able to relax. His legs twitched some as he closed his eyes. He felt tired.

A deep chuckle sounded from the side of the room, a familiar aura making itself known.

"Oh little Nightmare~" The twisted monster cooed, cupping his sweaty King's cheek. The tired royal lazily looked up at the other, leaning into their hand. "Are you really going to sleep in the mess you made~" He teased, his free hand teasing the other's cock. Nightmare mewled, pouting heavily.

"T-Tired... I-I'm not... Not use to..."

"Not use to taking care of it yourself~?" A quiet chuckle left the other. "I know~ I was wondering if you would follow through completely. Then I made a bet with myself on if you did~" This got a tired, confused look. "If you never followed through, or stopped halfway, then I'll show myself to you~ However, I would never stay and only use you for sex." A whine sounded at that, tears burning his eyes some. "But, if you followed through completely, I'll return completely and be loyally by your side~" He cooed, kissing the top of his lover's head. "You completed it all~ More than once~" He chuckled, pulling his sticky hand away from the other's cock.
