Noelle Holiday was positively buzzing with excitement. The young reindeer was rocking on her heels as she waited for her pick up from school. She wasn’t even slightly alone in this anticipation Kris was also looking forward to this little getaway. The school had found a significant mold issue and was going to be closed for four days and that inspired Toriel to take herself, Kris and Noelle out on a very special trip. To be fully honest Noelle wasn’t certain what to expect except that she would likely be having sex with both of her trip mates. Since the night when Noelle had confessed to having seen Kris and Toriel engaging in sex, and the consequences that followed that action, she had been on a romantic and sexual joyride. Noelle had developed from a minor crush on her teacher to a definitive sexual attraction. The Mistress of the Dreemurr household very much returned her feelings and as a result Noelle was receiving a thorough education in sex acts. The reindeer had the pleasure of learning just what it felt like to be in the boss monster's tender embrace, touched and teased until she screamed with delight. Noelle very much loved her “mommy” and Toriel loved her “daughter” just as much. Noelle got a rush from calling the older woman her mother. It was perverse and taboo but pleasing the goat sent thrills through her being. Noelle had just as much fun with Kris, or as she had started thinking of him as her “brother”. Admittedly, The first night she had spent with Kris he had been a female thanks to Ralsei’s magic. Noele had still enjoyed herself greatly in the act of pleasing Kris and herself under Toriel's watchful eyes. If Noelle hadn’t already been sure of her attraction to other ladies that night told her for sure. Learning that Ralsei of all people was the catalyst for the Dreemurr household’s lustful nature was a genuine shock to her. The Darkener Prince had turned up at about noon the next day and was ecstatic to see Kris was busy eating out the reindeer. Noelle had gasped as the goat monster who seemed so shy whipped out his truly monstrous cock and began fucking Kris. Noelle had cum on the spot watching her friend be filled to the brim. Ralsei had been more than eager to please her as well, playing with her breasts and calling her Sis. Noelle actually passed out from how long the Goat monster kissed her. Ralsei had finished up with Kris and was balls deep in Toriel when Noelle woke up. Her mommy encouraged her to take her brother for a ride since he was clearly eager. Kris was quite the sight, It was a shock to realize just how little her friend changed when returned to male. The one glaringly obvious exception was his rod which was impossible to miss. Seeing it up close was fairly intimidating and while she had fantasized about Kris taking her ever since that study session she had been underestimating just how hung he was. In the end though she spread her sex open and invited her Brother inside. Kris had not disappointed and it wasn’t long before he was positively howling for him to fill her up. Kris nudged Noelle out of her reminiscing with his elbow and gestured to the car. “Come on, let's sit in the back seat Sis.” he said with a smile that sent shivers through the Reindeer’s body, she knew what that smile meant. Noelle nodded, hopping into the backseat of the car and buckling up. She glanced up to where Toriel sat in the driver's seat as Kris got in and buckled up as well. “Remember you two safety first and you have to clean up any mess you make~” Toriel said as she shifted into gear and pulled away. “Yes, mommy.” The teens chimed as they leaned into each other’s space. Kris was very assertive about what he wanted from Noelle and she rarely found a need to protest. As such it was hardly a surprise when his hand slid up her thigh under her skirt to stroke along her sex. Noelle obligingly spread her legs to let Kris touch her more. “Hey Sis, would you return the favor?” Kris whispered into her ear and Noelle shivered as she undid Kris’s fly and pulled his stiff cock out. Noelle knew this was just a warm up for their weekend but it was already going so well. The reindeer’s hand flew up and down her “brothers’ cock as his fingers rubbed and pressed against the lips of her sex. The pair leaned into each other's bodies more and more as the trip went. Noelle squealed into Kris’ mouth as he kissed her suddenly, the passion pushing her over the edge. A second later she felt the tell tale throbbing of his cock as Kris came his hot load landing on his shorts as much as her hand. Noelle slipped into a blissful slumber shortly thereafter --- The little cabin was far enough away from town to not be bothered by basically anyone. Toriel got everyone inside and their clothes (most of which would not be worn) stowed away. “Now then children… I do believe Ralsei was going to join us but he said it might take a couple days.” Toriel said as she shed her clothes revealing the soft lacy looking lingerie underneath. “So in the meantime I have a few house rules. “No means no, obvious enough. I want everyone in no more than underwear unless we go outside. And of course, what mama says goes right?” “Yes Momma!” The teens said quickly, stripping down their underwear and then deciding that they had to go to. Noelle’s heart raced just standing there naked. The Dreemurr’s (and Ralsei) had given Noelle a very thorough education on her kinks. Perhaps the one that was the most intense was her thing for incestuous roleplay. Just after that was her desire to be observed fucking. The feeling of Ralsei and Toriel’s eyes upon her as Kris had taken her had lit a fire in her that saw her cum at least three times. The reindeer had learned the same day that she loved being praised for her sexual deeds. Ralsei, Kris, and Toriel had all spent time that first day praising her for her efforts to please them and how sexy she looked performing various lewd acts.. Kris was the one that helped her discover that she was into risky sex, not so much the risk of getting pregnant but the risk of getting caught. Kris had grabbed her no less than three times since that day yanking her into some technically concealed space and then fucking her to a quick orgasm. Being yanked into the seldom used janitors closet had been an eye opening experience. Noelle had been much more into it when he guided her into the boys bathroom. Noelle had never been more ecstatic than when he pulled her around the corner of the school to a recessed alcove and pinned her against the wall. Toriel knew that hiding behind the shy reindeer’s smile was a submissive and needy sexual beast waiting to be unleashed. Toriel encouraged Noelle by providing her with some toys to use at home and affirmations that Noelle’s turn ons were just fine. More than that though Toriel’s affections had a warmth to them that went beyond sexual gratification, it was something Noelle couldn’t place herself. Noelle just knew that being held in the goat monster's arms was blissful even if that was all they were doing. Ralsei had perhaps the slimmest relationship with Noelle even if it was no less sexual. Ralsei, like her, was a people pleaser and as such the two of them kind of tripped on each other when it came to group activities. Ralsei was slightly less submissive than her and he loved making her cum especially if Toriel or Kris was watching. Noelle gladly took him however he wanted or more often how Kris or Toriel wanted them together. Ralsei had some definite signs of nymphomania and was possibly more into the incest angle than anyone except Toriel. “Now since you two got a little fun in the car I'm calling dibs on Kris’ cock.” Toriel said as she planted herself on the couch her legs spread open invitingly. “Come to momma now.” “Yes mom.” Kris replied walking over with his erection bobbing left and right. Noelle turned to her bag, fishing out a soft gel sex toy and rubbing it into her pussy as Kris got started pounding his moms cunt. Noelle moaned watching the pair go at it fantasizing about what would come next. Noelle moaned as she watched Toriel smother Kris between her breasts, the human’s hips not even slowing. Noelle’s voyeuristic delight had totally ruined porn for the reindeer. It was so obvious to her now how they were faking it or how they stopped themselves from finishing. But when she had access to a show like the mother and son before her, who needed porn? Noelle came as Kris pulled back panting and sweaty, his cock throbbing as he pulled it from Toriel's sex his cum oozing out. “Noelle honey, come clean up this mess your brother made.” Toriel requested with a crook of her finger and a lascivious smile. Noelle jumped at the chance all but shoving Kris out of the way to place her lips against the motherly monster’s sex. Noelle revelled in the mingled scents of Kris and Toriel. Her tongue scooped up Kris’s cum and the sweet juices of Toriel with equal delight. Noelle was not great at giving blowjobs despite her best effort; she tended to accidentally catch the boys with her teeth or gag herself. Toriel had been helping her improve bit by bit but not fast enough for the reindeer. Noelle loved the taste of Kris and Ralsei’s cum and their cocks but she just couldn’t take it like her mommy and it frustrated her. She had no troubles with eating out though it came to her with ease and she loved nothing more than when Toriel seized her by the antlers and used them to keep Noeelle focused on a sensitive spot. Noelle shuddered as she heard a particular moan from Toriel that almost always meant she was cumming. The reindeer grinned, lifting her head and licking her lips as she looked to her mommy for approval. “Oh my little girl you are just too good.” “Lunch?” Kris offered, having apparently taken the chance to prepare some sandwiches and drinks. “Oooh i hope you made me some!” Ralsei said, emerging from the hallway already stripping nude. “What the fuck!?!?” Everyone froze, Ralsei turning to just behind him where Susie was staring wide eyed at the naked assembly.
