A girl runs into a friend at a convention, and ends up being very naughty.


The mare didn't know how she allowed herself to get into this position, she had a boyfriend she loved and it wasn't really showing at the moment. Stephanie was on all fours cheating on him with a stallion who had flirted with her before. There was even a time she had considered a relationship with him. A loud bellow in her ear brought her back to reality and how she ended up here.

It was a lovely convention, and she had been having a bit of fun. Stephanie really wished her boyfriend had been there with her, would have made it a lot more fun. She was already having a tough time cause of her season, those urges to flag her tail for the stallions she had seen around. It was difficult to ignore, and tempted to give in to those urges. There were a few friends she had hoped to avoid, and one of them was standing in front of her right now.

"Hey Stephanie, how's it going? I didn't think you were going to make it." She let her eyes slowly roam over her friend Michel; he was a big stallion standing over six and a half feet tall. He was a bit heavy set, but that wasn't what was making her nervous. That heavy looking bulge between his legs, she couldn't help but let her eyes glance at was causing most of her problems. She found it difficult to keep her tail pinned down behind her, his musky scent adding to that difficulty.

Her nostrils flared, drinking in that thick scent of his as he stepped closer. "Yah changed my mind at the last minute." His hand reached out and slowly ran along her cheek, stroking some of the red streaked bits of her mane out of her face. A soft shudder ran through her body, his hand was tinged with his musky smell. Her voice was barely a whisper as she spoke. "W... what are you doing?" It took a lot to speak her words. "I have a boyfriend."

Those fingers ran along her muzzle, brushing the mare's lips slightly as he teasingly pressed one past her lips. Stephanie let her eyes drift close, gently sucking on that finger, groaning softly. Her ears perked up, listening as Michel spoke with that deep voice of his. "That's such a good girl Stephanie, suck on my finger." A few moments, she willingly sucked on that finger before pushing it out of her muzzle.

"M... Michel, stop it please." The big stallion drew her tight against his body, lifting her muzzle as he pressed his own to hers. The feeling of his lips against her own made her shiver. Stephanie balled her hands up and very weakly beat on his chest, but couldn't bring herself to break the kiss. A hand squeezing her rump made her nicker, his fingers squeezing her tender rump firmly.

"Come on little mare, I think we need to make a stop by your room for a bit to chat." Stephanie nodded absently, biting her lip as she slowly started to lead him off.

"J... Just to talk, nothing else really." She looked over her shoulder, making sure Michel nodded an affirmative. There was a part of her this was a bad idea, but she needed some time to compose her thoughts.

Once in the elevator, Michel pushed her against the wall kissing her roughly. Stephanie moaned lightly at the feeling, she could his firm bulge against her leg. Every forceful caress, and touch to her fur made the mare want this more and more. Stephanie allowed her tail to flag slightly, finding it hard to resist. The stallion finally broke the kiss when the doors began to slide open, she allowed him to follow her to the room, letting her hips sway slightly with each step.

Once the door clicked close, his hands gripped her rump, pushing Stephanie back against the wall kissing her. The mare moaned into the kiss, her hands weakly pushing at his chest, struggling slightly as she felt her willpower starting to fade. It took quite a few moments, and a bit of strength to summon up the strength to break the kiss, panting heavily. "Michel... stop." Her nostrils flared, breathing in that musky scent wafting up; there was a tinge of arousal to it now.

"And what if I don't?" Stephanie groaned loudly, feeling his hand moving between her legs to stroke through the thin material of her shorts. She shook her head, arching her back, feeling that hand massaging her groin, making her fires of her arousal grow. It was so hard to resist flagging her tail, so she just held it up high behind her. She shivered, ears listening to his heavy pants knowing he was breathing in her thick fertile scent. "Mmm, Stephanie so you smell so wonderful... it's too bad your boyfriend isn't here to help you out."

She felt his hand grip her own, slowly pulling it to his crotch letting her feel the bulge there. Stephanie ran her fingers along that bulge, shuddering a little and began to slowly return the kiss. The mare felt it's heat and firmness through the fabric of his shorts, and she couldn't help herself and gave it a squeeze. That was a mistake; he wasn't lying when he had told her online that he was a big stallion. A few moments of stroking him, she composed herself breaking the kiss. She didn't remove her hand, but it took a lot of control to speak. "T... this is wrong Michel. You know I can't do this."

The stallion ignored her pleas, kissing her roughly as he made her hand squeeze his bulge once more. Stephanie ran her fingers along that bulge, shuddering slightly when he kissed her once more deeply. Her lips parted when his muzzle pressed to her own, his own lips parted and shared breath with her. Stephanie squeezed that bulge, moaning into the muzzle, her hand stroking and squeezing that lewd bulge. There was a little bit of a thrill that raced down her spine, listening to him moan in response to her touch.

"S... So naughty. You know... I have a boyfriend. We... got to stop." Though she couldn't bring herself to stop stroking that bulge, it felt easily around nine inches and thick. Her fingers squeezed and ran along its length, sliding up as her hand began to fumble with his buttons. Stephanie knew she had to stop, but the longer she did it, the more she found she didn't want to resist.

Stephanie lifted her head, feeling Michel's muzzle nipping her neck a little eliciting little moans from her lips. She lifted her hands to his chest, starting to undo his shirt buttons, feeling herself starting to lose herself to her season and needs. His hand was still between her legs, massaging softly and teasingly, making her whicker out lightly. Once she had his shirt open, she undid the stallion's shorts, that musky smelling shaft flopping free. His voice was deep and husky, groaning. "That's a good girl... how's my cock smell? Like a big virile stallion doesn't it?"

Nostrils flared, she moaned loudly whimpering as she felt her groin growing flush with heat and desire. She spoke up very softly. "S... so musky smelling." Her fingers wrapped around that dark piece of flesh, looking downwards. It was black like the rest of his coat, except for the white diamond on his forehead. His maleness was big, bigger than her boyfriend as she blushed. A little shiver raced down her spine, the muscles of her thighs twitching. It was getting so hard to focus, a little whimper escaping her muzzle closing her eyes.

"Yah sorry. Haven't showered yet, though you seem to enjoy it don't you?" Stephanie moaned softly, nodding very slowly. The mare hated the fact that her mound was soaked, partially from his teasing, and partially from his sweaty, musky smell. A little whicker escaped her muzzle, groaning weakly at the feelings his digits coaxed from her as they kept massaging her groin.

She didn't stop him when his fingers left her groin, starting to tug her shirt up and off. Once it was off, his hands moved down to and unbuttoned her shorts, pushing them down. His actions left her in nothing but the soft pink panties and bra she had underneath. Her ears perked up when he snorted loudly, the smell of her heated scent filled his nose. She blushed, ears folding back when he stepped back, pulling that thick length from her hand. There was a large bead of precum shining in the light, his head unflared between his legs. She bit her lip and glanced at him, eyes went wide when he stripped to his fur. Stephanie jerked her tail high behind her; she couldn't pull her gaze away from him.

"Michel!" Her voice was a high pitched squeak, eyes roaming along his black furred body as he stood there naked. A giant smirk was on his face, eyes staring into her own, and those deep brown eyes threatening to swallow her. His entire form was covered in rich looking black fur, on his forehead was the only break in that black coat. It was a perfectly shaped diamond splash of snow white fur. Stephanie allowed her tail to flag behind her, eyes glancing at the flesh between his legs, completely exposed from the sheath. It stood a full nine inches long, and looked thick, underneath was a heavy look pair of testicles. The mare felt a little flushed, wondering how much virile seed they contained, shuddering slightly and shaking her head to clear those thoughts.

"You seem a little overdressed... I think we need to fix that." Stephanie shivered when he stepped forward once more, those large hands of his roaming along her body. For some reason and against her better judgment, she allowed him to strip her down to her fur. Like his own, her body was coated in smooth black fur; the only color was streaks of blood red that ran through her mane and tail. Her eyes were drawn to a bit of motion, his shaft bobbing slightly; there was a large pearl of precum making his dark flesh glisten. Slowly, he reached around her, pulling off her bra off and freeing her breasts. The mare's nipples stiffened in the air conditioning of the room.

With her standing in the room, just in her panties with another stallion who wasn't her boyfriend meant she was breaking a lot of rules. Stephanie couldn't bring herself to stop though. She didn't resist when he moved her towards the bed, making her lean over it, breasts rubbing against the satin sheets on the bed. Willfully she flagged her tail, letting her fertile season spread into the air, making a bad situation worse. The longer she stayed in the room with him, the more likely she was going to let him mount her. She tried one last plea, desperately hoping he would listen to her. "Please... You have to stop. This has gone too far."

It was clear he didn't have any sort of intentions of stopping, her words turning into a cry when that thick flesh slapped against her panties. "Mmm just let me grind against you a little... no one will know, it'll help you." Those large hands of his, cupped her breasts lightly, fingers giving her nipples little pinches. The sensations made her shudder and moan out at the feeling. "Spread your legs... give yourself to me." His muzzle brushed against the back of her neck, his voice a soft whisper. Slightly little nips to her tender skin, even though she didn't want to, she found herself spreading her legs. It felt so odd letting a stallion grind that firm shaft against her panties instead of her wolf, it did succeed in making her moan out.

The only thought that kept racing through her mind was that she shouldn't have come to the convention in season. It felt so good having him on her back though, that firm flesh grinding against her pussy through the thin material of her panties. A little groan escaped her muzzle and against her better wishes, she wanted to feel more of that warm fluid staining her panties. His fingers felt so wonderfully nice, teasing and squeezing her nipples, giving them light little tugs.

Stephanie felt Michel's hips rocking against her, and she allowed her own to rock back to meet his motions, breath catching in her throat. The mare shuddered, feeling those large hands slowly leave her breasts, as he kept grinding back against her. She felt his fingers starting to fumble with the ties to her panties, she whispered. "W... what are you doing?" The stallion didn't answer, tossing the fabric to the side, his dark flesh rubbing firmly against her folds now. Every motion made it harder and harder for her to focus, the glans of his unflared head slowly spreading her winking sex. "S... stop... this is going too far."

"No, It's not..." His voice was a deep grunt in her ear; Stephanie arched her back feeling that naked flesh slipping inside her fertile passage. His words mixed with her deep moan. "Now, it's going too far..." She felt his hands moving to grip her hips, slowly sliding more and more of that aroused flesh deep inside her. They both grunted when his medial ring popped inside her, the stallion moaned in her ear. "Is this too far?" She could only nod weakly, feeling every inch of his strong flesh of that stallion as it filled her. It took every ounce of willpower and everything she had to fight that needy desire in her mind to speak, to cry out.

"Yes... too far... please." Her words dissolved into soft moans when Michel drove himself firmly into her wet passage, making the mare cry out. He felt absolutely wonderful inside her right now; would it be so bad to let him keep going? A slight whicker, she shook her head focusing once more. "No! Stop... please pull out." Stephanie's voice was soft and pleading, he didn't listen and a part of her was pleased he didn't. All the stallion did was kept stroking that thick length in and out of her, she could hear the soft wet sounds of their mating as it filled the air.

A grunt made her shudder, he was starting to thrust a bit harder now, his groin smacking against her rump. She could feel every jet of precum as it splashed inside her, the sensation making her whimper. This was such a dangerous game, but she couldn't make her body stop meeting his thrusts, the waves of pleasure threatened to swallow her up. Each time that thick medial ring slipped past her entrance, he made her moan and sent shivers along her spine. Michel's hand gripped the base of her tail, firmly holding it out of the way as she tried to flick it. Both of the horses breathing was starting to get ragged, their thrusts and motions firm as they met one another. Stephanie shuddered, unable to fight her body's needs, giving into the desires of her season.

It felt absolutely wonderful when she finally surrendered to those urges, allowing her sex to clench around that thick flesh. Michel said something to her, but she couldn't it out as her moans drowned out his words. There was something so soothing about a firm stallion buried balls deep inside her, she hated the fact it felt better than her wolf's maleness when he mounted her. She couldn't wait to feel him filling her needy body with his fertile seed, knowing how soothing it would feel. Stephanie gasped, remembering she wasn't on the pill and he wasn't wearing a condom! Unlike when her boyfriend was inside her, him being a wolf meant they needed special help to get pregnant, but with him being a stallion, it was all but likely if he came within her.

Stephanie was suddenly struggling under the stallion, his teeth biting her neck and holding her firmly as he drove himself into her powerfully. It was almost as if he knew the risk they were engaging in right now. She felt his cockhead starting to flare inside her, making the mare cry out in pleasure. It was such a different sensation that her wolf's knot, and it made her shudder. She couldn't make her tail stop trying to flick wildly side to side in the grip of his hand. The mare's thighs began to tremble, and Stephanie knew he was going to climax, all but sealing her fate.

Then it happened, Michel stiffened above her, suddenly hilting himself deep inside her fertile body. The stallion's hips grinded his groin against her rump, Stephanie imagined those heavy balls drawing tight against his body. His hands moved from her rump and tail, up to her shoulders suddenly pressing firmly, his heat flooding her. The stallion lifted his head, bellowing his lust and dominance out into the air, moaning her name. Stephanie couldn't help it as her eyes drifted close moaning out; she felt his glans flare lewdly inside her right before it shot that first spray of seed against her vulnerable cervix. The mare felt the stallion jerk his hips each time he sprayed another thick of his fertile seed into her body, and she was helpless to stop it.

She wanted to cry out, to say something, but couldn't as one of the most powerful orgasms she had felt in a very long time slammed into her. Stephanie's thighs trembled as she felt her walls milking that bare flesh, helping him knock her up. As much as she hated him right now, she didn't want him to stop or pull out until he was done. The mare couldn't believe how much she craved it right now, how much she needed it. Her voice was barely a whisper when she finally was able to speak. "Oh god Michel... I can feel it... I can feel it shooting inside me." Stephanie's eyes were clenched shut, letting the powerful stallion do what he wanted. After several minutes, feeling some of his thick seed oozing out around his shaft, he slowly withdraws from her body.

Stephanie shuddered slightly, not protesting when Michel slowly rolled her onto her back. It wasn't clear to her at the time why he was placing a pillow under her rump, the stallion grinned widely at her.

"Can't have my seed escaping can we? It needs to do its job." She sighed softly, feeling that thick heat slowly oozing deeper into her body, sensation making her pant. It'd hit her later with the meaning of his words, but for the moment she was still riding that euphoric high from that powerful orgasm.

By the time she left the convention, Michel had dominated her and had his way an almost dozen more times. The big stallion emptied his potent seed into her belly every time, and just like the first time there was always some part of her that didn't make him stop. Stephanie savored the feelings that raced through her each time she allowed him to violate her like that. Once she got home, she waited almost a week before fooling around with her boyfriend. The worst part, she only did it once she had taken the pregnancy test, confirming her fears. The foal that was making her belly grows big and round didn't belong to her boyfriend! She wouldn't let him know, as he was ecstatic that she had gotten pregnant, and was such a proud father bragging to his family.
