This story idea was given to me by Seduc1ove after I went on the forums and asked for further ideas, as my brain was drying up. We collaborated on the ideas so this story is for her.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Ever since his business had folded life had done nothing but kick Billy in the teeth. First he caught his wife cheating on him with his ex business partner and threw her out, and then she sued him for half of everything during a messy divorce, which cost him his home. Ever since then he had been staying at his younger sister's place.
There was his sister, Emily, her husband Mark and their daughter Jennifer living in the house and Mark had also been successful, even more so than Billy, and they lived in a four bedroom home on the outskirts of town. Emily had never liked Billy's wife so when he came to ask about staying, because of what she had done, Emily was only too eager to help her brother.
As Emily and Mark both worked, and Jennifer was either out with her friends at the beach or working at her part time job, Billy was often left to kick his heels at the house. Not that he minded, Emily was always trying to get him to go out and meet someone new, but Billy had already found that someone, it was just that she didn't know.
Most days as soon as everyone had left the house Billy would sneak into Jennifer's room, grab a pair of her panties, and slowly masturbate with them wrapped around his cock. He always made sure that the panties were washed and put away before anyone came home though, and today was just like every other day.
Billy was laying in his bed, his cock hard at the thoughts of Jennifer, when he heard the three of them all leave the house together. Waiting five minutes, to make sure they had all gone, he climbed out of bed and crossed the landing to her room. He opened the top drawer of her dresser, the one that contained her panties, and picked out a nice red satin thong. Going over to her neatly made bed, Billy climbed on to it lay down.
He could smell her scent on the pillow, which caused his cock to harden even more, closed his eyes and wrapped the thong around his cock.
Billy started to wank his cock, slowly at first, but he was soon masturbating furiously. He was so far gone that he didn't hear the front door open, or the footsteps that were coming up the stairs. Billy continued to wank as fast as he could when the bedroom door was opened quietly.
"UNCLE BILLY WHAT THE FUCK ARE YOU DOING!" Jennifer screamed at him.
Billy opened his eyes and was horrified to see his niece standing there. He sat up quickly, the thong still wrapped around his thick shaft, just as he reached the point of no return and started cumming. His thick, white, milky liquid began squirting from the end of his cock, all over the carpet, as Jennifer stood there, a look of disgust on her face.
"I said what the fuck are you doing?" Jennifer screamed again.
"Jen it's not what it looks like," Billy started to say.
"To me it looks like you are wanking with my underwear," she said. "Unless I am very much mistaken."
Billy's cock had begun to soften, a string of cum hanging from the end of his cock, and he stood up.
"Jen please don't tell your mum." Billy pleaded. "She will kick me out and I'll have nowhere to go."
"You should have thought about that you disgusting pervert!" She screamed.
Not thinking straight, fearing he was about to become homeless, Billy grabbed Jennifer's arms.
"I can't go through anymore shit." Billy said.
"Fucking get off me!" Jen screamed.
Billy let Jennifer's arms go and, not really meaning to, pushed her onto the bed. As he stood, looming over her, he just stared. She was extremely good looking, twenty-two years old with long black hair, a slim size ten body and small but perfect tits. She had gone out wearing a thin white blouse, which clearly showed her dark bra, and a pleated mini skirt and as he had thrown here on the bed the skirt had rode up, giving Billy a small glimpse of her black satin panties.
Standing naked in front of her, Billy's cock began to harden again.
"Just get the fuck out of my room!" Jennifer shouted.
"I told you to stop shouting at me." Billy growled.
"What the fuck are you going to do about it?"
"Maybe I'll just shove this hard cock into your foul mouth!" Billy shouted.
"You wouldn't fucking dare" Jennifer screamed back at him.
Before she could do anything Billy was on the bed, straddling her tits, and guiding his cock towards her mouth.
"Open wide Jennifer," Billy hissed.
"I fucking wo..." Jennifer began to say, before Billy rammed his cock into her open mouth.
Jennifer began to try and thrash her head from side to side but Billy held her still.
"All you had to do was shut the fuck up," Billy said.
Jennifer tried to speak but, having Billy's cock in her mouth made that impossible, instead started to beat his chest weakly with her fists.
"You're a feisty little slut aren't you?" Billy said as he began to fuck her mouth slowly.
Instead of continuing to fight Jennifer just lay there as Billy's thrusting got faster.
"Someone seems to be enjoying this," Billy said. "Maybe she would sooner have it in her pussy."
As soon as he said that Jennifer started to thrash her head from side to side again, but Billy just reached behind himself, lifted her skirt fully and ripped her panties off.
"Billy please don't!" Jennifer pleaded.
Billy was too far gone to care. He knew that as soon as her parents came home she would tell them what he had done. Mark would probably beat the living shit out of him and then he would be on the streets again. Removing his cock from her move he moved down her body and looked at her neatly shaven pussy. He could see that, despite all her protestations, her pussy was already wet.
Her juices were glistening on the edge and he ran his fingers over them.
"It looks like somebody isn't being very honest with me." Billy said.
"What the fuck do you mean?" She asked.
