Cross waited patiently for his boyfriend to finish their four-year surprise. NM said it was for him only. Cross jumped slightly as he felt two hands press against his back, warm breath hitting his neck and making him shiver. The very regonizable voice of his lover spoke lovingly.

"Hey, Cross~ Did I make you wait too long?" He asked, his tone sugar sweet. Cross blushed brightly, knowing he was in his passive form. He shook his head and felt NM's body press against his own, the warmth making him grip the sheets. He was positive that his face looked like a cherry at this point.

NM told him to close his eyes. He reluctantly did so. He heard NM run around and face him, before he felt a weight in his lap, and two fragile arms wrap around his torso. Cross's breath hitched, NM licking his neck and grazing his tongue along the vertebrae. NM smirked at his reacation, gently nibbling at his collar bone. Cross moaned softly, the sheets tearing slightly under his hold.

Cross couldn't take it any more. He pinned Nightmare down to the bed, grinding against him and kissing him roughly. NM moaned loudly, his hands against Cross's chest and legs around his waist. Cross pulled back, panting heavily and looking done at NM for the first time.

He was wearing a rather short shirt, a black top, and stockings, his shoes scattered in the floor with the rest of clothing soon to follow. He licked his lips, grinning down at a very flustered and submissive Nightmare. This was gonna be fun~! NM blushed brightly as Cross looked him up and down hungrily.

"All this, for lil ol me~?" He cooed, his hands trailing done his body and grabbing the hem of his shirt. NM blushed, looking away and squirming beneath him. Cross smirked, pulling the shift up and over his head, before quickly tearing off his skirt. His stockings and undergarments were the only assortment of clothing on him." Hm, you look so tasty~ I could just eat you up~"

With that, he attacked the other's neck, grinding his new erection up against him. NM moaned loudly, gripping his shirt and pulling him closer. They broke for a second of air, before kissing again. NM slowly undressed his lover, running his hands on his now exposed ribs. He pulled off Cross's boxers, sliding off his own. Cross thrusted in with no warning, making NM scream.

Cross pulled out until only the tip was in, and slammed back in at full speed. NM arched his back in pleasure, the bed creaking under the pressure. Cross grunted, pounding into him. NM screamed, when Cross suddenly slowed his pace. NM whined and bucked his hips as he came to a full stop, his member still inside of him.

(Warning: Daddy Kink. Don't like, don't read.)

"Cross, move!" He snapped, gripping his shoulders.

"Hm, I'm gonna need you to beg, sweetheart." Cross smirked. NM flushed brightly, but smirked back.

"Please~ Fill with your hot cum, daddy~" Cross turned bright red, grinned, and slammed into him roughly.

NM clawed at his back, scratching it as he felt a knot build up in his stomach. Cross did as well, striking NM's g-spot repeatedly. NM gripped his skull, screaming in ecstacy. Cross grunted, slamming in and cussing NM to cum heavily. Cross slammed in a few more times, before cumming.

Cross collapsed onto NM ribcage and panted, NM as well. NM kissed his skull, Cross pulling the sheets over them and cuddling him. NM smiled softly and slowly drifted off to sleep. Cross snored softly.

On the other side of the door, the rest of the team was exchanging bet money. Error had better they'd have sex, everyone else disagreed. Guess who just got 200,000,000g richer?

The End

Sorry if it's rushed! Bye~
