Around three in the morning, Fenne was awoken from her sleep.
It wasn't from something as simple as an alarm clock or a siren outside. Instead, it was something she dreaded the most. Something she could never escape from.
Her heat had hit, and she was 𝘧𝘦𝘦𝘭𝘪𝘯𝘨 it.
Beads of sweat formed on Fenne's brow, and she could feel her body begin to tremble. Normally, an omega's heat could easily be temporarily satiated by masturbation or even a pill, but currently, Fenne was unable to do either.
The reasons were simple. First, she had stupidly left her pills by her bedside. And second, arguably most important, she had agreed to sleep in her younger brother's bed since he'd been having bad dreams. Said younger brother, Ruppe, was blissfully unaware of his sister's predicament.
Fenne bit her lip, weighing her options. Her body was slowly overheating, and the haze was starting to affect her. She could either succumb to her body's natural instinct and risk waking her little brother, or try to resist the growing need to slide her hand under the covers.
Additionally, there was a third choice. She could attempt to slip from under the covers and make her way back to her own bedroom. Actually, that didn't sound too bad. She'd just have to be extra careful not to wake Ruppe, which shouldn't be too hard, right?
Blinking the fog away from her mind, Fenne very carefully removed the cover from over her body. There was an inevitable rustling sound, but she doubted it'd be enough to jostle her brother. That was until she suddenly felt an arm around her waist that made her heart drop to the pits of her stomach.
Ruppe seemed to be grumbling under his breath as he held Fenne close, preventing her from escaping. A quick glance over her shoulder told the omega that her brother was still asleep. He was naturally clingy, but to hold onto her while sleeping was a new level of strange for the young man.
Unfortunately for Fenne, his possessive touch had only intensified the feeling of her heat. She let out an involuntary whine, her body was pent up with unreleased energy, and her scent was slowly growing sweeter. Her condition was getting worse, and Ruppe wasn't letting go for a second.
The haze of the heat had nearly consumed her mind, and tears formed at the corners of her eyes as she felt a sudden emptiness within her. She couldn't take it anymore. There was only one option left.
Cursing under her breath, Fenne's hand slid under the covers until it rested over Ruppe's. Without thinking twice, she guided his hand down to her underwear where her erection pressed urgently against her boxers. It wasn't as good as being filled, but it'd have to do for now.
As she checked behind her to make sure her brother was still asleep, Fenne began rutting against his hand. Her hand spread over his fingers, opening his palm so he cupped her bulge. The relief was immediate, with the outline of her dick twitching against his warm hand. It was wrong, but Fenne's rational thinking had left the room along with her self-control ages ago.
Ruppe's breathing was still even, signaling his unconscious state. The fact that her brother was unaware of the depraved act she was doing somehow brought the omega even more pleasure, and she found herself grinding harder into his hand.
Slick pooled in her asshole, steadily leaking down her thighs. She desperately wanted to reach behind herself and give it some much-needed attention, but that was too risky. Ruppe was still right behind her.
"Fuck, shit..." *She swore in a whisper, another low whine leaving her lips. Her orgasm was fast approaching, a dark, damp spot forming in the tent of her boxers. The movement of her hips grew messy and uncoordinated as the pleasure hit her hard, and it wasn't long until she was spilling into the thin cloth that protected her brother's hand from the mess.
Her breath hitched as she rode out the euphoric feeling, her hand tightening over Ruppe's. After a while, she slowed down and allowed her hips to roll lazily against his hand, a few weak spurts escaping her tip.
Once the feeling of urgency subsided, Fenne's eyes widened as she realized what she had just done. Luckily, Ruppe's eyes were still closed behind her. She made sure to be extra careful when she slipped out of the bed, replacing her warmth with a pillow for her brother to hold.
And as she slipped out of the room, she missed the way Ruppe's hand flexed. If she stayed a few seconds longer, she would've seen him opening his green eyes and staring down at his hand as if he were remembering the feeling of her clothed cock.
"Stupid big sister..." He mumbled to himself, clutching the pillow that still held Fenne's scent. The poor boy was very confused, very embarrassed, and very, 𝘷𝘦𝘳𝘺 hard.
