Screw work, Sam wants to see what happens next

"Oh fuck" Ellie exclaimed as she tried to catch her breath "You're as good with your tongue as you are with your dick"

The guy lay back facing Ellie. For the first time Sam saw his penis - this guy was hung.

"Well I think it's time to find out if cumming in your mouth feels as good as in your pussy" His voice seemed familiar but Sam couldn't place it.

Ellie climbed forward and positioned herself between his legs. She reached out and grabbed his dick, raising it up and slowly started stroking it. Sam looked on in envy at at the thick, nine inch long cock.

"You want me to put this big thing in my mouth and suck you off?" she asked in her most innocent and playful of voices.

"That's exactly what I want you to do"

Ellie lowered her mouth to the tip of his penis, a smile spreading across her face as she got closer.

"Oh, okay then" she said innocently as she open wide and took the head of his dick in her mouth.

Sam watched in awe as his Ellie's head bobbed up and down, driving her partner wild from the sound of his moaning. His dick was rock hard from watching. Even in the vast array of porn he'd watched he'd never seen a woman suck cock with such wild abandon. Without thinking his hand slipped inside his trousers and he started stroking his dick to the sight of his gorgeous twenty year old step sister blowing another man.

Ellie momentarily released his dick from her mouth. "Did I tell you that I'm known as the cock sucking queen?" she asked

"A well earned title" the guy replied as he leaned forward and kissed her. For the first time Sam saw the face of the man Ellie had been screwing and his heart stopped cold.

It was John. The guy who had bullied him throughout high school, the guy who had spent years making Sam's life hell, the guy who had handed out numerous taunts and beatings to him. He was the guy that he'd witnessed fucking his sweet and innocent step sister. He was the guy who's cock she was sucking as if her life depended on it. He was the guy that Sam had been watching while he jerked himself off.

Sam felt sick at the entire situation. What on earth was his step sister doing with such a vile excuse of a human being? But his disgust at Ellie was broken by what he was now seeing in her bedroom.

Momentarily she had stopped sucking Sam's bully's dick, although she held it mere centimetres from her lips. "Want to see something neat?" she asked, but before John could reply she had opened her mouth wide, and slowly, inch by inch, she took all nine inches down her throat.

Sam marvelled at the performance Ellie was putting on - not only did she fuck and suck like a pro but she was able to deep throat. Five, ten, fifteen seconds she held it in before she eventually released John's saliva covered penis from her mouth.

After a few deep breaths Ellie slid John's dick back into her mouth, pumping the shaft of his cock as she sucked on the head. Sam could only marvel at the sight of Ellie, her magnificent breasts swaying gently in the morning night as her hand and mouth worked together on John's dick.

Sam didn't care anymore whose cock his step sister was sucking, he'd never seen anything anywhere near as erotic as this before. His hand slipped back down his trousers and started beating his hard cock as he fantasised that Ellie's lips were wrapped around it. It wasn't long before he found the release he needed and coated the inside of his pants with his cum.

Momentarily stunned at what he'd done Sam took one last into Ellie's room. "Oh god, I'm going to cum" groaned John as his body spasmed and he pumped his load into Ellie's mouth, who diligently and lovingly sucked every last drop of semen from his dick.

"You really are the cock sucking queen" he told her when he finally got his breath back.

"And don't you ever forget it" she replied before kissing his dick and sliding her body on top of his.
