Sparkpelt winced as Alderheart plucked the thron from her paw. The aftermath stung and she could see blood welling from the hole it left.
"Oh! That's a really big one," her brother's eyes were wide. "That must've hurt. Lick up the blood and I'll soothe it in a second."
Sparkpelt did as he ordered. It began to feel better immediately. Alderheart came over a moment later and put some herb or poultice or something on it. She didn't know; she wasn't a medicine cat.
"How does that feel now?" Alderheart asked.
Sparkpelt tested it. It felt fine but cried in pain when she put pressure on it. She yelped as she tried standing on all fours. "Too sore."
"Hmm..." Alderheart thought. "Perhaps you should stay in the medicine den overnight."
"What? Overnight?" Sparkpelt stared at him. She had warrior jobs to do! Things needed to get done!
"Well, what else are you going to do, walk on out of here?" Alderheart argued. "Besides, you'll be in good company. A medicine cat and a brother."
Sparkpelt grumbled. "Fine." She limped over to a moss nest and slumped down.
"Hey, cheer up!" Alderheart padded next to her. He laid himself down beside her so that his head was next to her hindquarters and his hips beside her face. His scent was strong. "If you're so down, I have an idea that you might find fun."
"What is it?" Sparkpelt dared to ask.
"That is, only if you're up for some fun~" Alderheart teased. His eyes glittered mischievously. His tail thumped against the ground.
Sparkpelt raised her head and turned to meet his gaze, surprised. She knew exactly what he meant. "Wha- now? In the medicine den? Wh- what if someone walks in?"
"Ah, we'll be fine," Alderheart dismissed her worry. "Leafpool is out and Jayfeather won't be back for a while. We'll be quick."
"Well..." Sparkpelt sputtered. "What about-"
"Do you want to or not?" Alderheart asked bluntly.
Plap! Plap! Plap! Plap!
"Aaaaahh~ fuck! H- hhaahhh~ Alderheeeaart!!" Sparkpelt moaned breathlessly. Before she knew it, Alderheart was on his back, thrusting up into her as she rode on top. "Y- you're so much bigger than last time! Uuugghhh~!"
Her brother speared deep into her, reaching balls-deep and thrusting straight into her womb. He smirked and maintained eye contact with Sparkpelt while she panted and shouted love to him.
Sparkpelt could feel his thick cock thrusting in and out of her pussy. She was dripping wet, allowing his dick to easily slide and scrape at her walls. She let Alderheart bounce her up and slide down from each hump.
"Alderheart... you're gonna make me... Nnnngggghhh~!" Sparkpelt shuttered as her orgasm rocked through her. She came all over her dick, coating his groin and balls in her clear, sticky fluids.
"How's this for some medicine?" Alderheart teased. He seemed to enjoy watching his sister bounce on his cock. "I bet you're feeling much better now."
"Ohhh... Alderheart~ fuuu..." Sparkpelt moaned. Still recovering from her orgasm, she let her mouth hang open and her tongue roll out as she panted. The bliss was only ever increasing.
They continued like this for another minute. Sparkpelt was glad Alderheart didn't mind doing all the work. She could just ride him and moan her heart out.
"Mmmmhhh~ I think I'm gonna cum soon..." Her brother groaned and sped up his humping. He pounded his sister's pussy relentlessly. Sparkpelt turned into a moaning mess.
Thwap! Thwap! Thwap!
Alderheart's eyes sparkled with both bliss and mischief. "Now, haahh~ you'll be a good girl and take everything that I give you, right?"
Sparkpelt managed to nod. He wasn't exactly hitting her G-spot, but he was close enough for her to experience euphoria. She felt his cock throbbing inside her.
"Nnnngggghhh! I'm cumming! Fuck!" Alderheart hilted himself as far as he could go in Sparkpelt, balls against her ass. Sparkpelt could feel his cock plusing before a pleasant white warmth began to fill her, flooding her insides and packing her womb.
"Uuugggghhhnn~ Fucking StarClan..." Sparkpelt moaned. Some drops of cum dribbled out of her cunt, but most of it stayed inside her as her brother pumped more shots of cum into her womb.
Finally, Alderheart relaxed and let up on the force he pushed into Sparkpelt with. His climax was about over. "Hah... Hope you enjoyed that... Haven't had a good nut in a while."
Sparkpelt nodded drowsily. "I think it did. I can't believe we haven't done this since we were apprentices." She glanced down at her warm and full belly, and then met Alderheart's eye. They both knew.
They were going to be parents very soon.
