Frisk woke in a bed of golden flowers. Sitting up, he was shocked to find that he had no bodily damage despite the massive fall he must have taken to have landed where he had. He'd not wanted to be back home anymore, he'd been shunned for how he was too many times, but he didn't want to be dead. He looked himself over as he stood up, finding no damage on his short skirt, or even his FBMs. He was still physically fine, and more to the point, still fabulous.
He shrugged, supposing it didn't matter so long as he was alright. He looked around the room he'd landed in, finding that there was a sort of hallway leading to another room. He stepped out of the flower patch and started down the hall, pausing slightly as he did. He could have sworn, just for a second, that there was someone else there. He'd been so sure that he wasn't alone, that there was someone or something else present.
He shrugged it off when he didn't see anyone else present though, deciding it must have been nothing. He headed down the hallway and into the new room. It was dark and empty save for a doorway to the rest of the cave, and another golden flower in the center of the room. It was different from the other flowers though, as it had a face. A bright, smiling, welcoming face, which helped to offset the oddity of it being there.
"Howdy," The flower greeted him as he approached, "I'm Flowey, Flowey the flower! What's a cute girl like you doing down here?" He asked. Frisk giggled at this, "Why, am I somewhere I shouldn't be? Can't be too bad if I got to meet you." He said, not corrected the flower. Flowey launched into his usual routine of explaining souls, the Underground, and LOVE.
Unlike the previous times he'd done this with the other humans though, the conversation had an air of flirtation to it. He wasn't sure what was compelling him to act this way towards her, other than her natural looks, until he saw her soul. It was red, but not the pure red of determination. It was a darker shade, between a scarlet and a cherry; the soul of lust. Flowey grinned as he decided to have a little fun with this timeline, his vines moving over and beginning to creep up her leg. "You know, there is another way I could help you improve the strength of your soul~" He said.
Frisk smiled down at him, "Gonna show me some 'love'~?" She joked, making him giggle cutely to keep up the act as his vines reached up under her skirt and to her panties. He had no intention of being gentle, as the thought of utterly destroying the girl with something lewd was an amusing one.
His vines reached her ass first, poking and prodding it as the other reached in for her pus… Flowey's eyes widened as he felt not a wet, warm hole with his second vine, but a stiff, twitching member. Flowey stared up at Frisk, but the human still appeared in every way female. He moved his vine down, checking if he was a futa, but no, he was fully male in spite of his feminine voice, appearance, demeanor and clothing.
Seeming to understand Flowey's confusion, Frisk said, "You can still call me 'she' if you want, I don't mind~" He purred, wiggling his feminine ass to get Flowey's vine to start teasing it again.
Flowey wasn't sure how to respond at first. Not gently, he knew that much. Dozens of vines rose up, wrapping around Frisk's legs and pulling him to the group, hiking up his skirt and holding his legs as far apart as possible, which was shockingly far, as the human was remarkably flexible.
"You need to be taught a lesson human, in this world, it's kill or be killed, take or be taken, or I suppose for you, rape or be raped!" Flowey laughed, but was surprised to find that Frisk was moaning from the painful way he was tied down, "Fuck yes Flowey~ teach me!"
Flowey, believing Frisk was just trying to play along so he could escape, dove four of his thicker vines hard into Frisk's ass. It was much, much tighter than he'd been expecting, and squeezed tightly around them as the human moaned, "Yes~!"
Flowey lashed at Frisk's ass with his free vines, but even this seemed to please him, making his member, now fully stiff, throb and twitch in excitement at the punishment. Flowey fucked the human's ass harder, forcing his vines in deeper and faster as he struck Frisk's ass harder, marking it grow red and marked.
Frisk tensed up, crying out as he came from the rough treatment. Flowey's vines stopped for a moment as he realized that the human truly did enjoy this. Before he could attempt to do anything about this though, Flowey fled to avoid a ball of fire thrown at him.
A tall, curvy anthro goat woman in an elegant purple dress walked over, "Do not worry my child," She said to Frisk, "I am Toriel, caretaker of the RUINS. I will keep you safe. I am sorry that horrid creature was doing such terrible things to do."
"Don't be, I deserved it." Frisk said, confusing Toriel. "What?" She questioned. Frisk nodded, "I was a bad girl Ms. Toriel," He lifted his legs, holding them skillfully behind his head, "I need to be punished~"
Frisk hadn't gotten Toriel to rape or dominate him yet, but he knew she wouldn't be able to resist for very long. She was so much more innocent than he'd expect for such a sexy monster woman. Frisk knew she had to have caught on to his flirting by the time she'd ask him to stay behind for a bit. Shed gone bright red when she asked him to practice stalling on a training dummy, and he'd responded by heatedly grinding on it.
He supposed he could wait for her. Every man and women he wanted eventually gave in, do unknowingly to his lust magic seeping from his soul and driving them wild. The only downside was that, on the surface, their opinions turned sour as soon as the lust wore off, and he'd be judged and abused for his actions, even when he'd not intentionally done nothing. But here in the Underground, Frisk figured he could try again as soon as he found another sexy monster.
Frisk didn't have to walk for long to find the first of them. It was a female, an anthro frog girl. She wore no clothing, showing off her lovely chest; which was oddly a darker tone than the rest of her body. Her legs were long and looked powerful, her expression was set as though she were on a mission, and her tongue, he was willing bet, would be pleasing long.
"Oh no!" Frisk exclaimed dramatically, "A sexy monster frog girl has trapped me! I'm doomed!" The frog girl didn't seem to pick up on his play acting, and seemed to believe his actions were legitimate. She wasn't the brightest of bulbs it seemed. Frisk smiled as he moved closer, "Perhaps there's some way I could convince her to let me go~?" He asked, hiking up his skirt.
The frog girl gasped when she saw that he had a cock, having been assuming from his appearance that he was female. Furthermore, his cock seemed to be locked in a cock ring, which would prevent him from cumming no matter how badly he needed to. He'd given Toriel the key, and though she didn't yet actually know what it was for, he hoped that she wouldn't untie him until he was a drooling mess at her feet, broken and loving her punishment.
The thought of the goat woman embracing her dominance and making Frisk her bitch nearly distracted him from his current mission, and he didn't have time to react as the frog girl forced him to the ground. He wouldn't have stopped her if he had been ready to, but he might have been able to better brace himself for the wall. The frog girl got on top of him and slammed her hips down hard enough to make sure that it hurt Frisk.
Frisk groaned happily at the pain. The frog girl moaned as she began riding his bound cock, loving how it twitched and throbbed inside of her. She let out her tongue; sure enough, long and slick. It moved over, wrapping around Frisk's hands tp prevent him from using them before looping back down and pushing into his mouth; either as a gag, a forced makeout to show who was in charge, or both. Frisk was hoping both. Not the best place she could have put her tongue, Frisk thought, but still very, very enjoyable for the sub boy.
Whimsun had taken a little more effort for Frisk's magic to turn dominant. The fairy girl seemed naturally submissive, and Frisk's flirtations only seemed to frighten her. He kept trying though, coming up to her gently and calmly sitting with her, talking to her as a friend, and letting his lustful magic work its charm. Whimsun gradually opened up more and more, his magic, as well as his being so kind, filling her with more confidence.
Things reached a head when he offered to share his monster candy with her. When Whimsun agreed, Frisk popped the candy into his mouth and pulled Whimsun on top of him, kissing her heatedly and passing the candy into her mouth with his tongue. She was bright red from the action as Frisk leaned in to whisper, "I want to apology for scaring you earlier, so how about I show you what else I can do with my tongue~?"
Whimsun was still nervous, and a little more gentle than he would have preferred, but Frisk knew that, with a little practice, she'd be a wonderful dom, and he was happy to help her get there.
Vegetoid's vines were a surprise. Frisk found the plant girl hiding and ready to attack him. She may have been after his soul, but his magic quickly turned her aggression into something much different, and her vines began undressing him before she even knew what she as doing, needing to stuff his girly ass and pump it full of her thick seed. Frisk pleaded with her to be gentle with him, knowing it would only egg her on.
She held Frisk against her while her vines lashed hard against his ass, reddening it with the force. When he was crying out and begging her to use his body, she pulled him against her body, two thick vines slamming hard into her ass, pumping into it roughly as another slapped against his already pent up cock. She wasn't going to let him go until he was too stuffed to walk properly. Frisk was going to need her fucking number.
Frisk got slightly frustrated with Moldsmol when he encountered her. The slime girl was laying on her back, looking up at the ceiling for no apparent reason, with no apparent goal in mind. She hardly even tried to attack him, simply swatting at him gently as though trying to get him to leave her alone.
Even when she was visibly aroused from his magic, and more importantly his sexy hip wiggling, she didn't make much of an effort to do anything. But Frisk was not one to give up, and so laid down next to her, letting his lustful aura get her more and more interested until finally she decided to go for it, climbing on top of the human and trapping his cock inside of her.
It was odd, as he was able to see his cock inside of her, even as he felt how tight it constricted around him. he shuddered in delight, knowing that if she were just a little more active, this monster could make an incredible dom.
Migosp and Loox were quite a surprise. The former seemed to be of a species comprised entirely of alt. genders, and he'd luckily stumbled upon a dick girl. The latter was on a species with rather interesting characteristics, such as his member splitting into two thick cocks instead of one. The two of them jumped out at Frisk, having evidently planned an ambush. Their desires turned from combat to pleasure the moment they saw him.
Frisk allowed the monsters to force him into his fours, the d-girl Migosp thrusting aggressively into his mouth to fuck his sexy throat while the Loox rubbed both tips against his girly asshole, thrusting both of them in roughly so he and Migosp could spit-roast the lustful soul. Frisk moaned in delight, bound member throbbing with want as he was railed. He was so tempted to ask if one of them could use their magic to unlock it, but no, he wanted to save his cum for the sexy goat woman.
Napstablook had been the hardest in the RUINS to handle, other than Toriel. But where Toriel was a tough nut to crack because of her resolve, Napstablook just had no drive to do anything other than lay on the floor. It was actually quite depressing to see the ghost boy just laying their, pretending to sleep in the hope that Frisk would leave them alone.
But Frisk didn't give up that easily. He laid himself on top of Napstablook, whispering to him, "No one should have to sleep without a nice war sleeve to put their member in~" He ground his soft bubble butt against the ghost's cock, half expecting the ghost to phase through him. But no, Napstablook didn't phase away, Frisk's charms keeping him solid, in more than once sense of the word.
When his member had gotten to full hardness, Frisk pushed his hips down, penetrating himself with the ghost's cock. He groaned softly, moving his hips until Napstablook's seven inches were completely hilted inside of his warm ass. Once he was balls deep, Frisk stopped moving, holding still as she held onto Napstablook, his lust magic pouring into him.
He only lasted a few minutes before needing more. His hips started moving slowly, pushing in and out of Frisk's ass slowly. She moaned exaggeratedly, urging him to keep going. He picked up the pace little by little, and soon Frisk was bouncing rapidly on top of the ghost, his cock hitting deeper and harder inside of him. Frisk squeaked in surprise and delight when Napstablook rolled over, pinning Frisk beneath him and beginning to thrust into him from above, his cock hitting his prostate hard, sending waves of pleasure through him.
Frisk moaned in delight, tongue starting to lull out. He thought the constantly pleasure and the build up in his balls might make him black out. As he neared unconsciousness, he could have sworn her heard something, a voice whispering something to him.
I wonder if I'll get a turn to..
