He continues the massage

Stevie could feel his cock throb hard as it hovered over his sister's smooth and shapely ass. As he slowly worked his hands up and down her back and into her shoulders he struggled to keep his cock from touching her. Emily let out soft moans as he worked out all the knots in her back and shoulders, all of her stress from her situation melting away. As he ran his hands up and down her back and along her shoulders and neck, Emily began to forget about her predicament and her pussy grew soaking wet as she instinctively parted her thighs. Stevie's cock jumped hard and shot a little precum at the sight of his sister's dripping cunt. He fought hard to keep his hard shaft from touching his sister. But the sight of her soaking wet pussy and the sound of her sexy moans combined with her squirming didn't make this task any easier.

Emily smiled as she said softly, "Oh god, you're so good at this brother. Your hands feel amazing! You are such a good brother for doing this for me." As she began slowly grinding her hips, she continued, "Mmmmm feels so good! You think you could you do my butt and thighs?"

Stevie's mouth dropped and his cock twitched at her request. His hands slightly shaking, he replied, "Uh sure sis... anything you say..."

"Mmmm thanks bro!" Emily replied in a sexy voice as she spread her legs even wider beneath him, his cock now less than an inch from her ass.

He was relieved that so far she hadn't noticed his hard cock, but he knew it would be hard to hold back his lust much longer. Emily let out a few sexy moans as Stevie began to slowly work his hands down the small of her back to her soft and shapely ass. Stevie groaned as he felt how perfect his sister's ass was and slowly worked his right hand down towards her thighs. Stevie scooted back, straddling her knees and using his left hand to brace himself on her back. His cock throbbed, now mere inches from his sister's cunt. Her pussy was so wet that her thighs were soaked with her pussy juices. Stevie groaned as he took in the sight of her dripping cunt and the feel of her hot juices all over her smooth sexy thighs.

As Emily scooted back, raising her butt into the air, his fingers slid towards her pussy and she let out a soft moan as he barely touched her swollen lips. Her soft moans intensified as she kept her eyes shut and slightly grinded her hips against his fingers. Noticing her lack of protest, Stevie pushed it even further, caressing her soft lips and thrusting the tip of his finger inside her, amazed at the heat and tightness of his sister's pussy. Emily cried out with pleasure as he thrusted his finger into her cunt and massaged her clit with his thumb.

Her whole body shook as Emily cried out, "Oh god Stevie! I'm gonna cum!"

As Emily thrust her pussy against his finger and suddenly raised her butt in the air, Stevie lost his balance. The sudden thrust of her body threw him off balance and his left hand slipped on his sister's oily back. He fell forward and his hips landed on top of his sister, his throbbing cock sliding easily into her hot, wet pussy. Emily screamed with pleasure as she rode out her orgasm with her brothers throbbing cock buried deep inside her. Stevie groaning with pleasure as his sister's tight pussy squeezed his cock. Coming down from her orgasm, Emily threw her head back, her soft brown hair tossing back sexily as their eyes met. Emily's face was contorted with a mixture of pleasure and shock, her eyes wide and her body shaking with lust as she softly said,

"Oh god... Stevie! Your cock... is ugggghhhh god... in me!"

As the siblings lay there face to face, Stevie only groaned with lust as he ground his hard cock inside his sister's hot, wet, and oh so tight pussy. They both shut their eyes and moaned as Stevie gave a few light thrusts into Emily's pussy. Emily moaned as she bit her lip in indecision. She knew the risks of letting Stevie fuck her... one drop of his cum and she would be knocked up by her own brother... his **** for life. But on the other hand his cock felt amazing inside her and she always had a huge crush on her brother. She knew that she had to decide soon, her body betraying her as her pussy fluttered around her brother's cock. Does she try to stop him or does she succumb to their mutual lust?
