You smiled softly as you walked through the snow, it crunching under your f/c shoes. Today was the day you and your boyfriend, Nightmare, had a date in Outertale. You found a quite secluded area, which had a nice view of the stars, and sat down. You grabbed the red and checkered blanket and carefully laid it onto the ground. Afterwards, you put out some sodas and sandwiches, admiring your work. "heya, y/n." God, how you loved the way your name rolled off his tongue. You turned around and tucked your h/c strands of hair behind your hair. "Hey! I got everything set out for our date." You said, scooting over to give the dark skeleton enough room to sit next to you. He chuckled before sitting down and wrapping an arm around you. "i"ll tell ya one thing, ya sure picked a good ass spot. has a real nice view." You hummed softly and rested your head against his shoulder. The two of you began to eat and made small talk, Nightmare talking about how annoying Cross was, blah blah blah. You began to space out, (pun intended) until you felt Nightmare grab at your ass, giving it a gentle squeeze. "y'know.. i'm still pretty hungry. i think i'll have ya for desert doll~" He purred, pulling you onto his lap. Blushing, you pushed him away gently. "B-But what if someone s-sees us?" You stammered, heart hammering out of your chest. Nightmare rolled his eyes. "nobody comes up here anymore, y/n. it's far away from civilization, so the chances of someone coming up here is practically slim to none." You nodded and allowed yourself to relax slowly. "now let's get those clothes off ya, yeah?" He snickered, pulling off your blouse and undoing your f/c lacy bra, causing your breasts to bounce in the process. Nightmare let out a soft moan at the sight and wrapped his phalanges around them, roughly squeezing. You gasped and bit your lip in attempt to stay quiet. Nightmare narrowed his eyes and leaned down and bit your shoulder, causing you to scream out. He grinned and formed a few tentacles, allowing them to pull off your pants and panties, leaving you completely exposed and nude. "Sing for me, y/n~" You whimpered softly and felt your entrance tighten as he reached down and rubbed at your clit. Fuck it, you couldn't hold it in anymore. You moaned out loudly, eyes rolling into the back of your head as Nightmare slipped two fingers inside your pussy, thrusting them in and out, causing you to come undone as you orgasmed. You panted and grinded down on them, desperate for more. He snickered and wrapped a few tentacles around you, shoving one inside you and thrusting it in and out as he pulled off his pants and boxers, releasing his throbbing dick from its confines. You licked your lips at the sight. "N-Nightmareee..." "yes, doll?" He grinned, beginning to stroke and rub his length, making you all the more needy. "I-I need you i-inside me!" You screamed, panting heavily. Nightmare hummed with content, setting you down onto the ground before crawling onto you, lining his dick with your entrance before shoving in, causing you both to moan in ecstasy. He bit down onto your chest, drawing blood, making you let out a small squeak as tears rolled down your cheek from the intense pleasure. "N-Nightmare I'm gonna c-cum again!" You croaked out. "m-me too! f-fuck!" The two of you screamed out as you came together, Nightmare collapsing on top of you, panting heavily afterwards.
"i-i love you, y/n.."
"I love y-you too, Nightmare..."
