Bart awoke to an unwanted swathe of natural light attacking his blurry vision from the window. He was only vaguely aware that he was not in his own bed and alone. He groggily sat up on elbows and began to grin as memories of the night before raced through his mind. He grabbed his morning glory and gave it a firm squeeze which sent a rush of slight euphoria through his body. He thought about relieving himself like he did most mornings if he was not too hung over but the faint sound of running water caught his attention. He flung the sheets from his naked body and stumbled towards the bathroom door. He heard light humming coming from behind the shower curtain after he had quietly opened the door and realised it was Lisa. Hormones still raging from the night before, he crept up and pulled back the shower curtain to reveal his sister rubbing her torso with sweet scented soap.

"B-Bart!" she cried louder than she meant. "Don't scare me like that!"

"Heh, sorry Lis. I just got lonely in bed" he smirked whilst grasping his throbbing cock.

Lisa blushed at the sight and closed her legs tightly in a poor attempt to fight the pang of pleasure that shot through her. As Bart lifted one leg and placed it in the bath she moved back slightly to let him join her.

"Need a hand?" he asked as he took the bar of soap from her.

As she was too flustered to reply he gently manoeuvred her by her shoulders so she was facing away from him. Bart draped himself over her and began sliding the soap across her breasts causing her to shudder. He slowly rotated the soap up and down her torso until she was lathered up sufficiently. He then placed the soap on the edge of the bath and began rubbing her nipples between his slippery fingers. She had to steady herself against the tiled wall to cope with the pleasure.

"You like that sis?" he said cockily.

Her breathing became short and ragged as she slowly slid her hand down until her fingers encircled her clit. Noticing this he pushed himself against her until his cock rested between her butt cheeks. The warm water cascading down on the siblings seemed to increase the feelings of passion because at first Bart planned to take control of the situation but quickly found himself losing it as pure lust ravaged his mind. Lisa's eyes widened as she felt her brothers cock slid down her butt crack, brush past her tight hole and rest against her lips. He began to hump against her making his length slid up and down her opening, his leaking head kept making contact with her clit in the process.

"St-stop it Bart…" she let her fingers touch his protruding head and tried to keep it away from her clit before she came right then and there.

"I can't" he breathed heavily against her neck. "I need to fuck you…please Lisa"

He began to hump more frantically against her slippery fingers, desperate to gain entrance. Lisa broke away from their embrace, turned to face her big brother who was as flushed as she was and smashed their lips together whilst wrapping her arms around his neck. He clasped his hands around her smooth behind and pressed their naked, wet bodies together so his member grinded against her navel.

"Do it…" she whispered against his mouth.

He didn't need any more convincing. He wrapped his hand around his eager member and guided it until the head pushed her tight opening.

"N-No…In the bedroom"

"If that's what ya want" he said, fighting back his frustration. "You go and I'll just give myself a quick wash"

"No!"

"No?"

"P-Please don't shower yet…" she whispered, burying her embarrassment at such a request.

"You're a kinky little thing aren't you?" he grinned as he ran his fingers through her wet hair.

Bart switched off the shower, pulled back the curtain and clambered out. He was already in her room, sat on the edge of her bed waiting for his little sister to join him. She walked in with a towel around her waist and started drying her legs.

"What are you doing?"

"Just drying myself, why?"

He quickly gripped an edge of the towel and pulled her towards him but before she could say anything he yanked the towel from her still wet body, tossed it over the bed and brought his face right in front of her shaved pussy and ran the tip of his tongue up the slit until it prodded her already swollen clit causing her legs to buckle. She threw her head back and inhaled sharply when Bart swirled his tongue around her most sensitive spot. Lust had consumed her once more.

"Oh god…Bart…" she managed to utter before gripping his hair and pushed her groin against his face until his nose was pressed against her pussy. At this point he was licking frantically, making her juices trickle into his mouth and down his chin.

"Now…fuck me now"

Bart gave a final flick with his tongue before standing up and delving it into Lisa's mouth so she could taste herself. Without breaking the passionate lip lock he pulled her down to the bed so she laid on her back and he was on top of her writhing frame. His pre-cum smothered cock was grinding at her pussy, purposely missing her tight hole, teasing until she could not take it anymore. She pushed at his chest so their frenzied kissing came to an end. Face flushed and breathless, Lisa gave her brother such a pleading look he almost felt guilty.

"Bart…" she whimpered. "Please…please, I need you inside me"

"Heh, if you insist Lis" he winked.

With that said, he sat up so his knees were either side of her ribs and shuffled forward until his glistening cock was centimetres from her face

"Care to lube me up bit first?"

He barely finished speaking before his little sister wrapped her lips around the tip of his cock. He hunched forward and breathed deeply as she took his length in her hand whilst swirling her tongue around his throbbing head. At this point she released his member from her mouth but held it firmly in front of her face. There was no hint of strategy now as she just wildly flailed her tongue around the head, enjoying the taste and scent of her brother.

"W-Woah, stop, I won't last two minutes if you keep that up" he laughed.

Lisa gave him a seductive look as she released her grip on him; a string of saliva kept them connected until he began shifting backwards.

"You sure you're ready for this?" he asked, getting in position.

"Y-Yes…just do it Bart"

She had suffered enough, time to put her out of her misery. Lisa parted her legs so he could lay in-between them. He gripped his slick cock and guided it towards his goal. He gave her one of his heart melting smiles before pressing the tip against her moist entrance. The sensation alone made her clasp her hands over her mouth, she let out a loud moan into her palms as his head breached her inner walls.

"Fuck Lis…you're tight!" he said with a slight pained expression.

Lisa could not really reply as she was experiencing pleasure she never though was possible with every inch slowly entering her. Finally he was all the way in to the point where their groins connected. He placed the palms of his hands near her shoulders and straightened his arms as he slowly slid backwards loving the muffled whimpering noise his little sister made when he firmly plunged his cock deep inside her once again. He kept this position whilst slowly manoeuvring his hips back and forth so he could thoroughly enjoy the desperate expression on Lisa's flushed face. He wanted to take his time as he had waited years for this moment but raw lust completely took over any sense he had, to the point where he could not control himself. Suddenly Bart moved his hands underneath his sister's armpits and slid them across her back until they cupped her quivering shoulders. Now they were face to face, Bart shoved his tongue into her open mouth and swirled it around inside frantically. The muffled moans emanating from the siblings were so desperate that skill was no longer involved, just wild and forceful humping.

Lisa lost all control. Once she managed to break the frenzied lip lock she began to lick her brother's face rapidly before pulling his head down to her neck so his tongue could continue its eager assault on her sensitive area. She tried to utter his name but as he increased his speed she was rendered speechless.

"L…Lis…I'm gonna explode!"

With that said, she wrapped her arms around his sweaty neck and let her moans of satisfaction out. Hearing his little sister exclaim loudly every time he forced his member deep insider her made him hump her even faster. Within moments her wails of passion became too much to the point where he fucked so hard and fast that they could both hear his balls slapping against her dripping pussy. Finally with an almost animalistic squeal from Lisa, Bart gave one final thrust as he unleashed his warm, thick cum inside his sister's swollen pussy. He collapsed on top of her; their bodies were stuck together in a hot and sweaty mess as they tried to regain their breath. Eventually Bart slowly released his almost flaccid penis from her now delicate insides, earning a last sharp breath, and rested beside her, enjoying her flushed face.

"So…I hope I didn't disappoint" he winked at her.

Lisa turned to face him whilst still taking deep breaths, she managed to smile.

"Can we make this a regular thing?" She asked breathlessly.

"I was gonna ask you the same thing"

They both uttered an exhausted laugh, eventually falling asleep in each other's arms once again.
