A couple of weeks later, Rainbow woke up from the best dream she’d ever had in her life. She couldn’t even remember any specifics, just warm waves of pleasure all over her body. She stretched, feeling a slight shiver run through her at how good the gesture felt. Her wings fanned the air of her cloud home, and she found herself wishing her human coltfriend was here for an early-morning quickie. The idea ran through her head in a series of mild fantasies, and she shivered again, biting her lip at the thought of how nice that would feel.
She froze, the specifics of the way she felt finally registering. Oh no. Dangit, I’m in heat. It had to happen sooner or later; with most mares, it happened a couple of times a year, and her last one had been about six months ago. It was massively inconvenient, though, and the fact that she had a lover now was going to make it even more so. She shivered again. Even talking to him was going to be a little on the unpleasant side for the next week or so; even here, up in the clouds nowhere near him, she couldn’t get the sensation of his penis pushing into her out of her mind. Or his hands and mouth roaming all over her body… she wanted him inside her so bad. Those fantasies would be even stronger if he was nearby; being in heat was so unbearably distracting.
Rainbow shook herself. She was not going to jump him. She was in heat; she couldn’t have sex with a male right now without permanent consequences.
The pegasus ducked into her bathroom, taking the coldest shower she could stand. She was supposed to meet up with him this morning, and she needed to be able to talk to him without trying to pull his clothes off and pull him on top of her. Even under the cool spray, the taste of his tongue on hers, and the feel of his arms around her still swam through her head. Aw, man, this is gonna be a bad one, she thought, setting the water for an even colder spray. I may need somepony to help me out this time. Twilight, maybe? She still owes me.
She finally stepped out of the shower, shaking herself dry and wishing that pegasi felt the cold more acutely. Still, she felt a measure of her self-control had returned. Urges like that were usually at their worst right after she woke up. She hoped. She hadn’t had a lover during her previous heats, and that was supposed to make it worse. Rainbow glanced at a clock on the wall; she needed to go meet Lero, and soon. She toweled off briskly, trying to come up with a decent way to tell him that they wouldn’t be sleeping together for a week or so.
Rainbow caught him just as he was leaving his home. “Hey, Rainbow, you’re early!” Lero called, waving. “What’s the occasion?” He grinned at her. That grin made her loins surge again, and she closed her eyes for a second, mustering her self-discipline.
“Hey, big guy. I gotta problem, can we talk inside?” She was a bit curt, though she didn’t mean to be.
“Of course,” he said with a concerned frown. He opened the door, gesturing for her to precede him inside. She braced herself and walked past him, but she couldn’t help brushing up against him. The feel of his leg rubbing against her side and hip sent another surge of lust through her, and she felt an unexpected sense of gratitude for his weird nudity taboo. It was much easier to deal with brushing against fabric than it would have been to brush against bare skin. That soft, smooth skin, with the short, fine, soft hairs that just barely covered it, the slight saltiness of his sweat on her tongue…
Stop it. She told herself firmly, walking into his living room. Her tail was twitching like mad, but she couldn’t help that. She waited for him to sit down, and took her own seat on a chair facing the couch, far enough away that they couldn’t touch. The pegasus saw the confusion in the human’s face intensify.
She took a deep breath, looking away and avoiding eye contact. “I’m not going to be able to hang out with you today, Lero. Sorry. Got some stuff I need to deal with. And I’m not gonna be able to spend the night over here for at least a week or so.”
He blinked. “What? Why? Did… Rainbow, did I do something wrong?”
Rainbow frowned. “What? No, you didn’t do anything wrong, it’s me.” She risked a glance at his face. What she saw there was confusion, mixed with a growing fearful hurt that was all too familiar to her, and her heart nearly broke seeing it on his face. Oh goddesses, he thinks I’m dumping him! She was filled with the sudden, powerful urge to race over, jump up on the couch with him, and hug and kiss him to make it all better. That was so totally the wrong thing to do right then, because she knew darn well that if she got started she wouldn’t want to stop with just a kiss. Still, the urge was so strong it left her breathless for a second, wanting to kiss him, tear those clothes off of him, rub herself against that smooth skin while she told him that everything was okay…
Focus. She blinked, and waved a hoof. “Not like that, not like that! I don’t actually want to spend a week sleeping apart! Celestia’s sake, it’s gonna be like pulling my feathers out!”
Lero’s brow furrowed in incomprehension. “Um. Okay. So, mind telling me why you’re doing it, then?”
“’Cause right now, all I can think of is going over there, getting you naked, and making love to you over and over and over,” she exclaimed, her wings fanning the air, “And that’s totally something I shouldn’t be doing right now, ‘cause I’m in heat! Argh!” she growled, covering her face with her forehooves. “I don’t want kids! And if we have sex right now, I’ll have a kid! But I want you inside me so bad, want to feel you moving in me, and… mmm…” Her hips were shifting in eagerness, and her brain was clouding over. She smacked herself in the face with a forehoof. “Argh! See what I mean? Even just talking to you right now is kinda hard. Hard…” She shook her head again. “This heat’s a really strong one. I may just hide in my house until it goes away, but it may get bad enough that I need one of my friends to help out.”
He was stroking the hair on his chin, thinking. “Is there anything I could do to help? I mean, I could find or make a condom or something…”
“Condom, that’s something that wraps around your… thing…” her gaze drifted down to his groin, and she had to wrench it back up. He’d told her once about human mating practices; as much of a pain as it was to be in heat, Rainbow privately thought it’d be way worse to not know when she was in season.
“Yeah. Keeps the… er, fluids inside it.”
Rainbow shook her head. “No, that wouldn’t help, it’d make it worse. Without the… uh… squirting…” Her mind was suddenly occupied with the most intense memory of how it felt to have his semen pumping into her, the warm, sticky, gooey feeling of it shooting deep into her insides… she cleared her throat, fighting for clarity. “Without the squirting, it wouldn’t do anything but get me hotter. Otherwise, I could just get a cucumber or something and then be fine. As it is, I’m gonna need to find somepony with a cooler in a couple of minutes, or I might wind up sneaking back in here and doing you until one of us can’t walk, and I really don’t want to do that.”
Lero raised an eyebrow. He was way too calm for this whole situation, she thought. “A cooler? What kind of drinks could help you?”
“Drinks?” Rainbow asked in confusion, “What the heck do drinks have to do with a cooler?” The only answers that sprung to mind were amazingly perverted, and she knew darn well he wasn’t into that kind of stuff. They’d both talked about their fantasies with each other, and his had been nowhere near that.
“Um, maybe you should tell me what a cooler is.”
“Seriously?” He nodded. “Uh… a cooler helps a mare in heat. ‘Cools’ her a little, you know?” She rubbed the back of her neck. This conversation wasn’t really helping. It really wasn’t. “It’s… a fake rubber dong that a mare can strap on, it’s got a thing of salt water inside it that the one wearing it can squirt out the end with this mouth-held pump thing. It helps for a couple of hours, if whoever’s wearing it uses it right. I’ll probably get Twilight to use hers on me, she owes me from last time she was in heat.”
He looked at her oddly. “I thought you said you weren’t into mares?”
The question surprised her. “Huh? I’m not. Oh, wait, I think I see what you’re thinking, but coolers aren’t gay. It’s not even sex, really. It’s just… something a friend does for another friend, you know? Being in heat is seriously not fun when you don’t want kids, and mares help each other out when it gets to be too much. You don’t always need it, but when you do…” She trailed off, shrugging. “Coolers aren’t perfect, I mean, they don’t feel quite right, but they help some.”
The human had a thoughtful look on his face. “Dash… the worry is that you want to have sex, but don’t want to get pregnant, right?”
Want was a pretty darn tame word for what she felt right now, but she answered with a curt, “Yeah.”
“Um, have you considered that it might not be possible for me to get you pregnant?” Her eyes widened. No, she hadn’t considered that. “I mean, we’re totally different species. I know humans have twenty-three chromosome pairs, forty-six in all, and if you’ve got a different number than it should be pretty much impossible for us to have offspring. That’s not even counting the fact that my sperm probably don’t have the right enzymes to…”
“Hold it!” Rainbow exclaimed, jamming her hooves in her ears. “Don’t talk about sperm right now!” She looked at him a bit wild-eyed. “Listen, I’m gonna go check with Twilight really, really fast. If she says the same thing you’re saying… um.” It occurred to her that he might not want to have sex with a slightly lust-crazed mare. “If she agrees with you, would you be okay with mounting me? Or me mounting you, o-or whatever?” She’d gotten to enjoy the belly-to-belly sex posture he enjoyed so much that even in this state of mind it was the first thing that occurred to her. Pushing him down on the bed, straddling him with her back legs, holding him down with her forehooves on his chest while… Dangit, Rainbow, these thoughts are getting awfully rapey. Get ahold of yourself!
“Of course, Rainbow!” He said, with an enthusiasm that made her flanks quiver. “Have I ever been anything less than enthusiastic?”
He had a point. She steered her thoughts away from where that point might be located. He’d always been an eager participant when she’d approached him. He’d even been willing to engage in experimentation, some successful, some not.
“OkayI’llberightbackbye!” She said in a rush, darting out the door. She flew to Twilight’s quickly, almost quivering. She wanted him to be right. She wanted him to be right so bad. Sex in heat was supposed to be the best sex a mare could have; heck, it even felt pretty good with a cooler, something that Rainbow doubted would be much fun under other circumstances.
She landed in front of Twilight’s front door, taking a deep breath to calm herself and still her eager quivers. She knocked calmly, pleased that she’d managed to hold her exuberance back.
The door swung open. “Yes, can I… oh, hello, Rainbow Dash. How are you this fine morning?” She peered at her friend. “You look a little frazzled…”
“I’m great! Or, uh, I will be great, if this is right. If not, I won’t be so great. Man oh man oh man, I hope it’s right, ‘cause that’d be great.” Rainbow said, grinning, and knowing she sounded like Pinkie but not really caring.
Twilight blinked at her in incomprehension. “O-kay, you lost me. How about you start again?”
Rainbow laughed, with a slight edge of hysteria. “Okay, sure. First off, I woke up this morning and realized I was in heat…”
“Oh, dear!” Twilight exclaimed, “Is it a strong one?”
“Oh, man, yeah,” Rainbow answered sincerely, “Strongest one I can ever remember having. I cannot stop thinking about sex.” Another fantasy started running through her head, and she stomped on it with all four hooves. Jeez you’re getting perverted with these thoughts, Rainbow. And I doubt Twilight would be interested in a three-way anyway. And what the heck, you don’t like mares that way anyway!
Twilight eyed the pegasus warily. Under other circumstances Rainbow might have flushed guiltily, thinking the unicorn had somehow seen her thoughts, but right at the moment she didn‘t care. “Oh…kay. So, why are you so excited? I thought you didn’t want any foals!”
“I don’t! But that’s the thing! You know who I’ve been courting, right?” Twilight nodded. “Well, I was talking to him about it, telling him I was gonna have to hide out for a week or so, and he pointed out that since we’re different species there’s a pretty good chance we can’t have kids!” Rainbow grinned excitedly. “So I figured I’d ask you to be sure, but it sounded right to me!”
Enlightenment dawned on Twilight’s face. “Oh! I see! Wow,” she said somewhat enviously, “You could have sex in heat and not have to worry about pregnancy. That would be nice.” The unicorn tapped her chin with a forehoof in thought. “Well… I realize this may be a silly question, but do you know anything about his genetic structure?”
“Um… yeah! When we were talking about it, he said he had… uh, I think it was twenty-three? Maybe twenty-four… Chromomomosome pairs or something.” Rainbow had been trying to listen when he was talking about that stuff, she really had, but then he’d mentioned sperm and everything else had gotten kinda shoved out of her head.
Twilight looked at her incredulously. “Wait, are you serious? Only forty-eight chromosomes?”
Rainbow blinked. “I think it may’ve been forty-six, actually. Why? How many do we have?”
“We’ve got sixty!” The unicorn exclaimed. Rainbow felt a grin stretching across her face, as her friend continued, “If he really has forty-six, then he’s almost certainly absolutely right; there shouldn’t be any way the two of you could have a child.”
Rainbow really wanted to make sure she’d heard Twilight right. “So… we could have sex, and I wouldn’t get pregnant?”
The lavender unicorn nodded. “I believe that’s the case!” She paused. “You know, Rainbow, I’ve been meaning to ask what it’s… like.” The unicorn blushed. “You know. With another species.”
“Just curious, eh, Twi?” Rainbow chuckled, restraining herself from rushing back to her coltfriend. “Well, let me put it this way. I’ve always heard that the sex was way better when you’re in heat. In this case, I’m not sure how that’s even possible, and if it is, I’m a little worried I’m gonna wind up with, like, brain damage or something! Not worried enough to not do it, though.”
Twilight’s eyebrows climbed. “That good?”
“Better.” Rainbow sighed, happily, “You know how the first time with a new guy’s supposed to be quick and not real great?” Twilight nodded, a sour look on her face. “Well, the first time we did it? I came four times. Four. And he’s gotten better since then.”
Twilight’s jaw dropped. Her eyes glazed over a bit. “Um… do you think you’d be willing to let me, uh, borrow him the next time I go into heat?”
The pegasus gave a breathless giggle. “You’ve gotta ask him. He said he’d be fine with other mares courting him, but I don’t think anyone’s asked. Oh, and he doesn’t have much fur, so his skin’s all soft and smooth. It’s really sexy, honestly. And that’s not even mentioning his hands. Oh man!” She giggled again. If she weren’t so deep in heat, she’d be blushing like mad right now. “Those are the best. Only weirdness is that his thing’s got a kinda weird shape; it’s kinda pointy on the end instead of being flat. I haven’t had any problems with it, though.” She glanced around, making sure no one was nearby, and leaned in close to the unicorn. “And did you know he’s actually got nipples?”
Twilight blinked in surprise. “I thought he was male!”
“Oh, he is, he definitely is,” Rainbow giggled. “Human stallions have nipples like the mares do. He says they don’t work, but he’s got ’em! They’re way up on his chest, too, it’s kinda weird.” Rainbow chuckled again, salaciously, but before Twilight could say more, the pegasus’s impatience finally gnawed through her politeness and Rainbow turned on her heel. “I gotta go, Twi. If you need me, I’ll be busy. For, like, the next week. See ya!” The rainbow-maned athlete shot off into the sky before her friend could get another word in.
She rocketed back to Lero’s home, relishing the feel of air flowing over her wings. She touched down outside his door in a small whirlwind of displaced air, and quickly stepped inside. Her human friend looked up from the book he was reading. He raised an eyebrow. “What did Twilight have to say, Rainbow?”
She sauntered over slowly, eyes half-lidded, and reared to put her forehooves on his shoulders and look him right in the eyes. “She said you were right. You can’t get me pregnant.” She kissed him, long and lingering, wrestling his tongue with her own. “And I could really, really use a good rutting right now.” His eyebrows climbed a bit, and she added, “C’mon, let’s go to the bedroom.”
Lero blinked, surprised. She knew she wasn’t usually this aggressive with him where sex was concerned, (she’d been trying really hard not to get pushy) but it didn’t seem to be bothering him much. He set his book aside and she got out of his lap to let him stand, drawing her forehoof slowly across his groin as she did so. When he stood, she carefully took his hand in her mouth, pulling slightly to lead him to the bedroom. He chuckled and followed obediently, and the pegasus took the opportunity to run her tongue along the fingers in her mouth. The slightly salty taste and the smoothness of his skin made her heart beat even faster. Her anticipation was almost agonizing.
He stopped by the bed, and she hopped up on it. Standing on her hind legs, (and momentarily enjoying the fact that, standing like that on the bed, she was taller than him) she bent down, threw her forelegs around his neck, and kissed him deep and hard. He laughed a little nervously, and she knew she was going a little fast, but she couldn’t help herself. She’d slow down if he asked her to, but until then… With a quick twist of her body, she pulled him off his feet and threw him onto the bed, falling atop him. She giggled at his slightly shocked look. “C’mon,” she panted, “let’s get those clothes off.”
“Yes, ma’am!” He replied, a twinkle in his eye. Did he enjoy it when she got aggressive? She’d ask later. She helped him strip, accidentally tearing his shirt a bit while she pulled it off. He started to remove his pants, but she hopped down, grabbed the waistband in her teeth and yanked them off with a quick toss of her head. She’d barely noticed, but her wings had gotten incredibly stiff, something that normally only happened with direct physical stimulation that she hadn’t gotten yet. He started to rise, but she hopped back up onto the bed and pushed him back down with a forehoof.
“Ah-ah, big guy! No foreplay this time. Lie there and gimme a second.” She was panting in anticipation, looking at his nude form stretched across the bed. His member was hardening, but was nowhere near ready to go into her yet. I can fix that. She leaned down and ran her tongue slowly along his shaft, starting between his testicles and running it along the underside all the way to the tip. The human stiffened, his back arching slightly as she took his member into her mouth. She bobbed her head a couple of times, quickly, running her lips along its length, watching his face as she did so. His member lengthened inside her mouth, growing deliciously hard with gratifying speed, and she had the slightly mad urge to keep going. To just hold him down and keep fellating him hard and fast until he came, the delightful warm stickiness spurting all over her mouth and tongue, spilling down her throat.
She resisted the urge, knowing that the sensation of semen splattering the inside of her mouth would be nothing compared to having it squirt into her vagina, having him buried deep beneath her legs before shooting that sticky fluid into her. She pulled her head away, the saliva-coated head of his now erect penis standing proud.
Rainbow shifted position, pushing the human back into the bed again when he started to rise. She positioned herself atop him, his penis pushing at her vulva, her hind legs spread and straddling his lower belly, and her forehooves on his chest, holding him down and pressing him into the bed. Her loins surged; she really liked being in charge. Ordinarily, it didn’t make much difference to her who was on top, she liked it both ways, but right now being in charge was making her really, really hot. She grinned at him, and slid her hips backward along his belly, leaving his penis with nowhere to go but into her. She clenched her muscles, making herself as tight as she possibly could, and relished the feel of building anticipation as the head of his member pushed against her tight vulva. It finally overwhelmed her resistance, pushing past the outer lips and sliding smoothly into her vagina, the saliva she’d left on it and her own lubrication combining to make it almost frictionless. She moaned softly, feeling every single instant of his penis pushing into her. Rainbow wasn’t ordinarily all that vocal when they copulated, but this time felt incredible, even something as simple as being penetrated was only a step down from orgasmic. It was soooo much better than a cooler, because everything felt right, his member was warm, there was a very slight pulse to it that she could just barely detect, the slight give of the hard shaft as her vaginal muscles gripped it tightly was just perfect.
She pushed until it was all the way in, as far as it would go, and she could feel the slight squish of his testicles against her backside. Even that feeling was intoxicating, the softness against her crotch, the hard shaft penetrating deeply inside her, the feel of his smooth, almost-hairless body between her legs, oooooh.
“Okay,” she said huskily, “Listen up. You know that thing where you grab my butt with your hands?”
“Yeah?” He sounded a little breathless, too. Maybe he really did like it when she got aggressive. If so, they were gonna have to do this more often.
“When you’re getting ready to come, I want you to do that, and just push it in as deep as you can. Okay?” A thought occurred to her. “Ooh, actually, when you start coming, can you, like, pull back a little when you’re not squirting and slam it back in when you are? Oh man that would be great!” She shuddered a little at just the thought of how that would feel.
“I… I’ll try, Rainbow.”
“Yeah, yeah do that.” She started sliding, not actually moving all that much because she loved the way he felt deep inside her. Pulling a bit and then thrusting it back in… she bit her lip as the stroking lit a fire in her groin. She was already way, way past the point where she would normally have orgasmed, and every stroke felt better.
“R-Rainbow,” the human panted, “If you keep this up, I’m gonna come really fast, way faster than you will.”
“Mmmm…” she tightened her muscles, gripping and pulling a bit on him with the next motion. “I’ll come when you do,” she told him. She knew it was true, but couldn’t say how. The feeling of hot fluid spurting into her belly… the anticipation of it was almost agonizing. She started stroking harder, her groin slapping up against his rhythmically.
Finally, finally, he groaned quietly, and his hands grabbed her muscular buttocks. It was way quicker than they normally were, but it still felt like ages before it finally happened. Here it comes! She thought gleefully as he arched his back, thrusting deep into her. The feeling of that first glob of semen spurting into her was indescribable, like an orgasm but totally lucid. The world didn’t dissolve into swirls of color the way it normally did; she felt every moment of it with total clarity. He was as good as his word, pulling back slightly between spurts and slamming back in just in time for another glob to squirt into her. She could feel it, the delicious sticky fluid squirting even deeper into her, coating her insides. It was rapturous, and her tongue lolled out of her mouth with the sheer delight of it. He came long and hard, shooting his seed even more deeply into her, and she relished it.
When he was done, she didn’t even feel disappointed that it was over. A feeling of warm, relaxed happiness filled her, and she flopped down on top of him, panting with the aftereffect. He was still inside her, still hard, but his orgasm was done.
Panting, they stayed like that for several minutes, until his softening member slid out of her. She raised her head from where it rested on his chest and looked him in the eyes. “Oh. My. Gosh. That was fantastic. That was incredible!” She beamed at him, satiation spreading through her entire body.
“Glad you enjoyed it, Rainbow.” Lero let out a breath. “Wow, that was more intense than I thought it would be. Are you feeling better?”
“Yeah, much.” She stretched languidly. “Whoo. That was way better than a cooler would have been.” Rainbow eyed her human friend. “Um. You know this won’t last forever, right? I’ll start getting heated again, probably sometime this afternoon or this evening.”
“I’ll be ready by then,” he promised, eyes gleaming. “Maybe I’ll even tie you up next time.”
Even in her current state of satiation, the thought of combining the fantastic sex they’d just had with the pleasure she’d felt last time they’d played that game sent a bolt of lighting through her. “Uh…” She was speechless for several moments, finally concluding with, “I think that would be unbelievably great. You gotta promise not to tease me this time though; hard and fast is how you’ll need to do it.”
“I think I can do that.” His eyes twinkled. “By the way, I just wanted to let you know, I kinda liked you taking charge like that. It was… really sexy.”
“Really?” She wiggled her eyebrows at him, and he grinned. Goddesses, she loved him so much. He made her feel so pretty, so sexy. No one had ever made her feel like this before. “Well, I’ll have to do that more often, then!”
“Please do.” He licked his lips. “Not all the time, but as an occasional thing I don’t think I’d mind having you throw me onto the bed like that.”
“Can do!” She grinned. “But you already promised to tie me up next time.”
“Oh, I will.” He promised. “I even went out and got some better rope after last time. Good silk stuff, still just as strong as the stuff we were using, but this won’t be as scratchy.”
She chuckled, throatily. “You spoil me, big guy.” The pegasus nuzzled the human’s neck affectionately.
