After Sam hooked up with the teenager Ruby, his life turned around. He got a divorce from his wife, who now was really his ex-wife. He got a promotion at work, which allowed him to by another house. Sam's sex live was outstanding! Ruby came over often enough to keep his balls drained dry! Ruby was going to college and didn't move in with Sam, mainly because her parents were paying her tuition and Ivy League schools are very expensive. Whenever she would come home on breaks, Ruby made sure she got over to Sam's place to get thoroughly fucked! Ruby still had not found anyone close to her own age that did to her what Sam could.
This particular weekend Ruby was especially horny. She and Sam went at each other for hours! Sam was also very horny and together they fucked themselves nearly to exhaustion. Ruby was lying on her stomach and stroking Sam's semi-erect dick when she took it in her mouth it slowly became rock hard again. Ruby got over Sam's stiff member and lowered her well fucked and messy pussy down on it. Ruby slid down to Sam's balls and fully impaled herself on him!
Sam looked up at her big tits and took them in his hands and played with Ruby's erect nipples. After he had one nipple in his mouth Ruby asked him,
"Have you ever thought about me and you with another girl?"
Sam nearly choked on Ruby's tit. He bit down very hard on it and exclaimed,
"What?"
"You know, wouldn't you like to have two mouths on your dick? Maybe four hands all over your body? Or don't you think you could handle two of us horny young chicks?"
Sam figured he had to be careful, in case this was some kind of a test.
"Oh, I don't know. That is a universal male fantasy, two chicks. Why do you ask?"
"I have been bragging to a friend of mine how good you are and how big you are, so she told me to put up and share you or shut up!"
"So this is real, you are not just trying to find how much I care about you?"
"Of course it's real! I know how much you care, that's how come I thought I could ask you. I think we could include my friend and make us stronger! We both know we'll never get married to each other anyway!"
Sam thought this over for a while. He knew she was right, when she got tired of him she would dump him. Cautiously he said,
"Do I know whom you have in mind?"
Ruby ground her pussy against Sam's abdomen and said,
"Yes you do. She really wants to fuck you too! And that is sort of a problem."
"Sort of a problem, why?"
"She's my best friend and your niece, Norma!"
Sam was shocked to say the least! He'd never even thought of having sex with his brother's daughter. Ruby renewed her humping motions on Sam's stiff dick and he sort of got interested in getting off again. While Sam was fucking Ruby's delightful pussy he pictured Norma in his mind.
Norma was about the same height as Ruby. Norma had long blond hair and was on the slender side. Sam had never really seen her in anything very revealing, other than a one piece bathing suit, and that was about two years ago. He did remember she had great legs. The rest he couldn't recall. Norma had small breasts (A-Cup), a tiny waist, slim hips and she was perky cute. While Sam was envisioning his niece, Ruby increased her tempo and yelled out,
"Oh yes, I going to cum!"
