Family Fun 1: Sibling Sucking [MF] [Incest] [Oral]

*Disclaimer: All characters 18+.*

“Someone’s got a stiffy.” Kate laughed as she sat next to her brother on the couch.

“Shut up.” Jeff rolled his eyes and lazily put his hand over the erection in his shorts. “It won’t go away and I couldn’t stay in bed all day.”

“So jerk off.” Kate shrugged, grabbing the remote.

“Don’t you think I tried that?” Jeff groaned and leaned back on the couch. “It’s killing me.”

“Did you take something?” Kate flipped through channels.

“No! I just woke up like this.” Jeff gripped the boner under his hand to sooth the throbbing some.

“Ok, sorry.” Kate settled on a channel and leaned back next to her brother. “So what are you going to do?”

Jeff sighed. “I was going to hook up with someone but..”

“You couldn’t get a girl to come over.” Kate teased. She glanced down at Jeff’s hand. “Does it hurt?”

“What do you think?” Jeff grimaced at his sister. “It’s swollen and getting sensitive.”

“Let me see.” Kate said casually.

“What?” Jeff put his other hand over his erection. “No way!”

“I just want to see how bad it is.” Grabbing his wrists, Kate moved his hands away.

The bulge in Jeff’s shorts began to twitch as his sister stared at it. “You’re not helping.”

Kate reached out and ran her hand over his cock playfully. “Oh, you want me to help?” She giggled.

“Uhnnn.” Jeff groaned as she lightly gripped him through his shorts. “Seriously?”

Biting her lip, Kate stared at her brother. “Yeah… why not?” She gave him a small smirk.

“Oh.. uh… ok.” Jeff was shocked and a bit unsure, but his aching cock wouldn’t let him say no.

“A.. Alright.” Kate was a little hesitant as she reached for the waistband of his shorts, but her curiosity made her press on.

She pulled the front of his shorts down and Jeff’s throbbing erection sprung out, making her gasp. Jeff took a deep breath. He was more swollen than before, and had to resist pushing his sister’s head down.

“Oh wow.” Kate traced her fingers over his shaft, feeling the veins standing out along the length. “You weren’t kidding.”

She leaned in and kissed the tip of Jeff’s cock, making his hips jerk. She continued kissing and lightly licking his head and ridge while her fingers explored his shaft. 

Jeff groaned, his thighs trembling. “Uhnn Kate, please.” 

“Sorry.” Kate blinked from gazing at his cock. “Just.. impressive.”

Her lips parted and his tip slid between them. Jeff sighed as his sister’s mouth engulfed the head of his cock, the warm wetness the first relief he’d had all day. Kate gripped his shaft fully, starting to slowly stroke. Her tongue lapped and rubbed against his tip as her lips moved repeatedly over his ridge.

“That’s perfect sis. Just like that.” Jeff cupped Kate’s head and gently guided her movements.

“Mmm..” Kate moaned, her lips and tongue humming against his head. 

Jeff gasped and his fingers curled in her hair. Kate glanced up at him and bobbed her head faster. Spit trickled down from her moving lips, lubing his veiny shaft for her hand as it stroked up and down. Jeff’s hips started to rise and fall, matching the rhythm of Kate’s movements. She slid her hand down to fondle her brother’s balls and took his cock deeper into her mouth.

“Fuck..” Jeff steadily pumped upward, trying to control his instincts as he felt the pressure building.

“Mmhmmm..” Kate encouraged, letting his tip slide over the back of her tongue.

Jeff’s dick swelled and throbbed in her mouth. His balls tightened as she gave them a squeeze. He tightened his grip on his sister’s hair and pumped faster into her mouth. Kate matched his pace, lips running rapidly over his ridge and down his shaft. Her fingers kneaded and tickled his heavy nuts. 

“Awk!’ Kate’s eyes widened as his tip brushed the back of her throat.

Jeff groaned desperately when she pulled up, letting his dick out of her mouth, but still released his hold on his sister’s hair. Kate’s hand left his balls and immediately began to stroke his spit-coated cock while she caught her breath.

“Yes.. cum for me.” Kate cooed to her brother, her hand twisting and sliding along his cock.

“God yes. Fuck, Kate!” Jeff started to tense all over and his dick pulsed in her grip.

Kate leaned back in and quickly ran her lips over his defined ridge over and over, her tongue lapping at his leaking tip. Jeff shuddered and let out a loud moan. His aching dick exploded in relief, shooting spurt after spurt of hot cum onto his sister’s massaging tongue. Kate’s eyebrows furrowed as he filled her mouth, but she continued to slowly suck him off. Only once her brother had stopped trembling did she raise her head with sealed lips. 

Kate tilted her head back and opened her mouth, showing the pool of semen resting on her tongue. “Oh ma gah!” 

She closed her mouth and gave a loud gulp that made Jeff’s cock twitch in her hand. He took deep breaths as he came down from his orgasm and his sister tucked his dick back into his shorts.

“How’s that?” Kate giggled and licked a few drops of leaked cum from her lips. “All better?”

“Much.” Jeff sighed happily, his sore cock starting to go limp. “Um… thank you Kate.” He said a bit awkwardly.

Kate blushed and sat up straight. “Don’t mention it.” She patted his leg and stood up. “I’ll let you cool down before mom and dad get home.”

“Good idea.” Jeff sat up straight and adjusted himself. “Thanks again sis.”

Kate paused as she left the room. “Oh, and absolutely no one ever knows about this.” She pointed threateningly. “Or else.”

Jeff laughed. “Or else what?”

“Or else I won’t do it again.” Kate stuck out her tongue and winked as she left.
