Pound was startled awake from a deep sleep, slightly disoriented as he took in the dark ceiling and the walls of his bedroom as his eyes adjusted to being awake. He was trying to figure out why he was awake. It was still dark outside his window, so it must still be late… or really early.
He heard a quiet grunt and was jostled, realising what must have woken him up. He looked to his left and saw that his sister was fidgeting next to him, her half of the blanket was shoved onto him, no longer covering herself. She was laying on her back, huffing and panting, while her forehooves were hugging her pillow to her chest. She was biting down on a corner of the pillow while her lower half kept wiggling and twisting, causing the sheets to tangle with her hind legs.
“Mmm… sis… whats up?” He rubbed the sleep out of his eyes as he sat up. “What’s with the fidgeting? Got ants in your pants?” He asked with a yawn.
Pound looked over his twin sister, they have always slept in the same bed together since they were newborn foals. She was laying with her hind legs and tail spread across the bed, she was dripping with sweat from her head to her tail, little beads of sweat were forming on her chest and belly, rolling across her matted fur and dripping to the bed, her mane was a mess of tangled orange, and her signature hair ties were missing, lost in her restlessness, letting her mane bunch up into a big fiery tangle.
She moved the pillow down from her face, looking up at her brother with worried eyes. “I don’t feel so good... I think I caught a cold… or something,” Pumpkin said, then let out a groan and hugged the pillow up to her face again, biting down on the soft surface while her hind legs went into a fit of fidgeting again. “I feel really hot… and weird.”
“A cold?” Pound asked with a worried tone, he got out from the tangle of blankets and turned to face his sister, he put a hoof to her forehead, just below her horn. “You’re awfully sweaty, but you don’t have a fever.” He pulled his hoof back, wiped it on their blankets, then hopped over his sister with a quick flap of his wings and landed on the floor with a quiet thunk of his hooves hitting the hardwood. “What are you feeling?”
Pumpkin groaned and looked at her brother. “Achy, and hot…” She fidgeted some more, Pound’s eyes were looking her up and down, trying to figure out what was wrong with her. His eyes trailed down her belly to the little curve of her budding teats to the crease where her legs joined her body, and then to her filly parts tucked between her legs.
“P-Pumpkin, your thingy… it's all… red and swollen.” He stuck his tongue out in disgust. “And drippy.” He backed a couple steps away from the bed. “You didn’t pee the bed, did you?”
Pumpkin sat up at that. “Eh- Wh- What? No! Gross. I’m just… sweaty?” She said as she looked down at herself, she spread her legs a little wider to get a better look at herself, her eyes widening. “ My… thingy isn’t supposed to be… like this.” She tenderly reached a hoof down and poked at it, it was definitely more puffier than normal. Pound could see the way the flushed rosy red flesh squished under her hoof before she jolted and pulled it away with a flinch. A large drop of something wet drooled from the thin crease in her thingy and pooled onto the dock of her tail.
Pound gave his sister a worried look and stepped over to the door. “How about a hot bath? That’s what mom usually does for us when we get a cold.” He stepped out of the room, and a moment later Pumpkin could hear the water start.
Pumpkin gingerly hopped down from their bed and slowly followed after her brother, wincing slightly with each step as her filly bits were really tingly itchy, and she found it hard to concentrate when her thighs rubbed against her swollen filly lips.
She found her brother sitting next to the tub, watching it fill up as she stepped into the bathroom. She awkwardly waddled over to him and stood next to the tub, unable to stand still as her rear end kept fidgeting and her tail kept flicking around.
