Waking up the following morning, Dusk felt a strange feeling in his groin. It felt almost as if someone was sucking him off as he tried to sleep. Sighing a little, Dusk figured it was probably Pinkie breaking in to his house to give him a morning blowjob. Sighing once more, Dusk grabbed at the head of the girl who was sucking him off. But the moment he touched the head, his face became almost shocked and confused. What was expected to be the cool and squishy Pinkie Pie slime head bobbing him in such a sloppy manner, felt feathery and soft. Instantly, Dusk released his hand and pulled his blanket free, revealing the girl sucking him off wasn’t Pinkie, it was Rainbow Dash.

“Ah...what...Rainbow...why are you...?” Dusk asked, though his voice couldn’t help but let a small groan escape. But instead of a look of sheer disgust, Rainbow’s face was blushing heavily, and her eyes were glossed over with lust. It was as if he was looking at how Fluttershy looked. “Rainbow...are you...in season too?”

“It’s...your fault...” Rainbow commented, her words coming out between each bobbing of her head and some of her words came out as sultry moans as she suckled. “Fucking...Fluttershy...like that...with this...big cock...fuck you...I hate...you...I...want...you to fuck...my mouth...just...do it...”

It was impossible to tell if Rainbow was completely serious or not, but Dusk couldn’t deny how good she was on his dick. With no other choice, Dusk placed his hands back on Rainbow’s head and started pushing her over his cock, letting her take in more and more of his length. Dusk gritted his teeth, feeling Rainbow’s aggressive sucking only seem, to try and force out his cum. For a lesbian, Rainbow was shocking good at sucking cock. It was not her skills with a tongue, Dusk had already assumed she must’ve been good with that because of her relationship with Fluttershy. But it was how she sucked and boobed her head with such efficiency; it was like she had been this for years. Or was she just a nature cock sucker like Pinkie.

“Fuck Rainbow...I’m gonna...I’m gonna...” Dusk gritted his teeth, air heavily breathing from his nose as he prepared himself. Instinct took over his reasoning and with a solid upward thrust, Dusk rammed his cock to the hilt in Rainbow’s mouth just as he released a thick load of cum. “Cum!”

Rainbow gagged for a moment, but offered no resistance. She only bobbed her head harder to swallow more and more cum like some drunken whore. Dusk was shocked to see this side of Rainbow. Maybe she was in season too? If that was the case, then watching her lover being fucked must’ve really set her off and made her incredibly horny. Rainbow’s eyes rolled back as she swallowed gulp after gulp of Dusk’s cum, seemingly squealing in delight and pleasure a she came from the taste alone. Dusk gritted his teeth as he felt the harpy’s suction like mouth refuse to let go of his cock; even as he tried to pull himself free.

“R-Rainbow...” Dusk panted, his hands gently pushing on Rainbow’s head. “You’re sucking too...ahhh...too hard...”

Rainbow looked up at Dusk, their eyes meeting and staring into each other for an impossible length of time. A mix of hatred, embarrassment, lust, need, and desire burned from the bird’s eyes as she hated yet loved Dusk in this moment. She needed more than just to suck him off. She could feel her pussy dripping with want. She hated the idea, but he was the only cock she could even remotely attempt to trust. She want him to fuck her. Loosening her oral grip, Rainbow allowed Dusk’s cock free, but not before grabbing it with her wing claw.

“Listen here.” Rainbow ordered, her voice still aroused but serious. “I hate you, but I need you. What happens...never happened. No one finds out! So just shut up and let me get this over with.”

Dusk only nodded in response, wanting to help but not wanting to upset Rainbow further. Spreading her wings, Rainbow lifted herself, only to turn her small frame around and plant herself slowly over Dusk’s cock; but with her pride still disgusted by all of this, the harpy chose to face away from the human, giving Dusk instead a better look at her small, firm ass as it slowly lowered itself over his dick. Being a lesbian, Rainbow was not used to having a real dick inside her. It was massive in size compared to the soft and passionate tongue she would get from Fluttershy when they indulged each other’s pleasures.

“F-fuck!” Rainbow moaned, trying to hide how good it felt through empty complaints. “Just fuck, it’s too big...how did Fluttershy...” She turned her head slightly, seeing Dusk look at her through what she saw as perverted eyes. “S-shut up you...you...oh for fuck sake. Just...just get it over with...”

Dusk nodded silently, placing his hands on Rainbow’s hips. The sudden touch caused the sensitive harpy to squeal as she felt tingles surge through her body. Turning her head, Rainbow stared so intensely, it was as if she was trying to burn through Dusk’s face, but she said nothing; only blushing a scarlet red. Looking away, Rainbow fidgeted a little, letting the cockhead to slowly fiddle its way in her extra tight snatch. Rainbow’s hymen was by no means intact, her athletic life style ensured that. But with experience being only her own claw and Fluttershy’s tongue, an actual cock was slowly but surely going to stretch her out.

“Fucking...how can anyone...” Rainbow grumbled to herself, her moaning voice echoing out between her panting breaths. Wiggling her hips from side to side, Rainbow tried to ease her way in but only managed to get Dusk’s cockhead in at the most. The thickness inside her caused her eyes to roll back and her body to tense up; shivering as she felt only a fraction of Dusk’s length break through. “How can i get this thing to...”

Dusk, a small flicker of arrogance in his eyes, groped at Rainbow’s sides hard, causing the Harpy to coo slightly before he used his strength to not only pull Rainbow down on his cock, but simultaneously thrust upwards. This caused Rainbow’;s pussy to split open from the sheer length and girth, as well as the thick and hard cockhead to kiss at Rainbow’s tiny cervix. The harpy’s breath left her lungs in a soundless gasp. Her eyes were wide open, and her tongue dangled from her loose mouth. Turning to look at Dusk, the human thought he would be met with an angry bird. But Rainbow looked at him like some desperate slut. The feeling of being so forcibly opened up had caused a lapse in Rainbow’s thoughts. She only looked like she wanted to be fucked now.

Dusk only nodded, gyrating his hips up and down as Rainbow seemed to sway herself from side to side. The combined motion of the two as they fucked soon became a rhythmic, fluid motion. The harpy moaned louder and louder as she continued her bouncing, wiggling and and shaking. She could not get enough of the cock inside her; this first cock was shaping out her pussy for its own use and she was unable to stop it. Dusk couldn’t help but groan as he thrust himself upwards, ramming his length deeper and deeper into Rainbow’s body; her tiny pussy feeling almost bottomless as his length was begin swallowed whole.

“Fuck, Rainbow...” Dusk groaned, feeling the tight embrace milking at his cock; trying to get his cum to flow. “I’m gonna cum!”

“Fuck...I can’t...” Rainbow struggled to get up, not wanting to have Dusk cum inside her. But every time she got up, her legs gave out and she only slammed back down on Dusk’s length, causing her to twitch and moan in orgasm. “Just...just fucking do it!”

Dusk grunted, his cock swelling in Rainbow’s bird pussy before finally releasing his climax inside her. Rainbow’s mouth opened wide as she let out a squeal of pleasure. It was a feeling she had never felt, not even with Fluttershy. Her stared upwards as she realized how good this felt. The hot cum that bubbled in her womb, the thick cock stretching her insides, and how her body seemed to greedily devour all of it without a second thought. She was in a euphoric state. She loved Fluttershy, and always would. She hated all men, and always would. But Dusk’s cock was an exception to this rule now. Rainbow Dash was addicted to this feeling. It was something that she wanted again and again, and she would even share this pleasure with Fluttershy.

Dusk only lay back, his breath was heavy for a moment, but felt himself getting a second wind. Normally, the girl would sense this and want him to fuck another round, but Dusk could tell that one was enough for Rainbow. He was greatly confused. So much sex, in such a short span of a day or two, and yet he still had so much stamina left to spend. It couldn’t have been the clothing, nor could it simply be he was becoming more accustomed to the girls. This was something different, something special. It had to be something. But for now, all Dusk could think was how his life had just added another horny girl in his already sex filled day; completely unaware that the mark on his forehead was giving off a faint glow.
