Xerneas X Yveltal
Xerneas woke up on a Warm Autumn Day, feeling strangely hot with an urge to seek out a male. She knew this feeling far too well it was the need for mating. Unfortunately for her she wasn't able to mate with anyone except her Sworn-Enemy Yveltal. She's always hated him for as long as she and him were created by Arceus they represented life and death, polar opposites of one another, and they hated each other for these differences. She didn't even try to look for a male because they weren't big enough to even so much as pleasure her at all. However this particular mating season her heat was very strong, she tried to lessen it by going in lakes, and rivers but that barely changed anything, she wasn't sure what to do, she couldn't even masturbate due to the fact she was a deer, or do anything at all to relieve the Heat. All she knew was she needed a Male now.
Yveltal had woke up after a long slumber, when he noticed this very strong scent in the air, it smelt fantastic He headed towards it with great anticipation, till he got a few more breaths in and realized this smell, it was caused by a female's heat. Now he knew the only female that could produce something like this had to be Xerneas. However, he was addicted to that strong smell and followed flying above the forest line. That's when he saw her, Xerneas was laying down on her side, She got up and looked toward that direction, sensing the presence of a male, just to see Yveltal on top of a tree in front of her.
"How petty to see a Pokemon like you in this situation, Xerneas." He said, this made Xerneas really mad, and she screamed "Go Away!" Yveltal asked "Why should I? I don't see a point going anywhere else." Yveltal loved this smell and wanted to stay near her just to smell it, however doing this would put him in the same boat as the Female deer, so he couldn't stay around for too long, but as for the smell, picture your favorite food, being enhanced to smell better, and you have 1000x the smell you do. That's how it was for Yveltal simply amazing, She in reply to this said, "Because I said so!" In a much fiercer and louder tone.
Yveltal once again taunted her by saying "What a shame to see a one of a kind legendary in this situation you're pitiful too say the least." This really made Xerneas's blood boil as she tried firing Moonblast at him, which he quickly avoided "Wow Xerneas, must be the heat, huh?" he said. She screamed back "Why can't you just leave me here!" In a very fierce and angry tone. Yveltal flied Yveltal was starting to get aroused from the smell of heat and that's when he tried covering his nose and flying back, Xerneas laid back down thinking he was gone for good, she let out a sigh and whispered to herself "Why did Arceus make it, so we the only two legendaries that can be together.." but the smell was very strong, and he still couldn't resist it, he could see the result of the heat when he looked down and saw his member fully out, soon he snapped and went back to Xerneas's location, and onto the ground right behind her. Xerneas said "How many times do I need to tell you" getting furious she got up and got ready to charge at him, and she looked very shocked to see his member fully out.
Yveltal said "Xerneas do you see yourself right now pitiful I must admit, but I can help you with that" He said, Xerneas immediately getting at what he was saying said "I'll never mate with the likes of you Yveltal!" This answer didn't surprise him, so he gave Xerneas a grim reminder about the fact that no one else would be willing too, She replied "Well s-so be it." she said in an annoyed tone. "Now go!" This made Yveltal mad because at this point she was in the same boat as Xerneas then he suddenly tackled Xerneas then flew on top of a tree, her heat only getting worse. Xerneas asked why he was being so annoying, Vestal asked the exact same question. Finally, Yveltal went slightly further still close enough to both smell, and see her. He asked himself why she had to be this annoying.
Xerneas started pouting due to her heat and hitting the surrounding trees. Yveltal seeing this came back and made the offer one last time, Xerneas feeling like she had lost a war said "F-Fine... I guess, just make it fast."
Xerneas stood back up and let her private area become fully exposed. Yveltal inserted his member into her and slowly thrust, it felt very tight and super wet as well. "G-God Damn," Yveltal said, Yveltal then pulled out all his length except the tip and then did a very strong thrust which caused a sting to Xerneas and a yelp of pain from her. Yveltal said "it appears I have popped your cherry," he started thrusting in and out of her uncontrollably a soft moan left Xerneas, she was trying to hold back to not give him the satisfaction. Yveltal took about half of his length back and thrusted it back in at full force which caused her to let out another moan, this one however louder, Yveltal could tell Xerneas was trying to hold it in from how the moans sounded, this made him very annoyed, and he started thrusting mercilessly making it harder and harder for Xerneas to hold it back she let out a loud moan, and closed her eyes. To both Xerneas and Yveltal it felt like a fight, and she was getting dominated. Yveltal did 3 strong thrusts where he took his member out halfway and did a fierce thrust causing her immense pleasure, and her "Juice" to spill all over the grass beneath them. Yveltal feeling a weird feeling started thrusting rapidly and released Semen into Xerneas, the Semen was very warm, Although She didn't want his semen inside of her it still felt good. and he did 3 final thrusts causing her to release her "load"
Yveltal quickly pulled out and went over to her front then positioned his member into Xerneas's mouth. Which gave her a surprised look, and a small blush. Not sure what else to do she started sucking, she used her tongue to help move his member up and down, Yveltal shoved the length deeper and deeper inside Xerneas causing her to gag. She wanted to get this over quickly, so she started licking and sucking faster. "Mmmmmmm.." Xerneas moaned out as she continued sucking, Xerneas just wanted to be done with this, just because she mated with Yveltal doesn't mean that she liked, or even cares about Yveltal at all. Some pre-cum spilled into her mouth, which Xerneas wanted to spit out but couldn't due to Yveltals member being in the way, so she was forced to swallow it. The pre-cum seemed like a sign that Yveltal was close so Xerneas sucked as fast as she could use her tongue a lot, she could taste his semen from earlier on his member, which tasted kind've good she thought to herself. Yveltal let out a moan and then came inside her mouth.
After that, Yvetal decided he'd had enough and pulled out of Xerneas's mouth with a bit leaking onto her, then he flew off
Xerneas was annoyed at the fact that she was forced to make love to her rival due to her body. She sighed and went to clean off the cum that spilled on her from Yveltal.
Yveltal deciding he's had enough then pulled out of her mouth, and flew off without a trace.
