Cheating on wife with sister-in-law’s friend *Part 1*

This is my first time writing a story so i hope you all like it. My name is Jason and i live with my wife and roomate kim. I am 24, my wife is 26, and our roomate is 20. This story is about the first time my sister-in-law Sam (18yo) , her friend Alivia (17yo), my brother John (21yo), and I found ourselves naked together in my wife and I’s bed.

One day when my wife Danielle and Kim were working one of their mid-afternoon shifts till 4am delivering pizza (they work together at Domino’s), my brother, Sam, and Alivia came over to hang out and watch tv at our new apartment. Samantha is my wife’s younger 18yr old sister. She’s about 5′ 6, slightly past her shoulders length blond hair, and slim with moderate sized perky breasts and likes to dress punk. Her friend Alivia is 17 and much more gorgeous then most girls her age. With bright beautiful blue eyes, long curly dark brown hair and curves in all the right places, I can’t help but stare at her whenever she’s over.
Samantha and my brother John were standing by my dvd’s arguing over which movie to watch while Aliva and I were in the kitchen getting chips and dip ready. John and Sam have been flirting for the past week or so. My wife had told me this morning before work that Sam had told her that they’d fooled around for the first time last night. My attention at the moment though was focused on Alivia as she bent down to get in the cabinet under the sink for a bowl for the chips. Her perfectly rounded ass made my cock twitch slightly in my pants. I could see the top of her red g-string sitck out the top of her jeans. What I wouldn’t give for a chance at a night with Alivia. Since I’d known her, I thought I sometimes caught glimpses of her glancing at me when I wasn’t looking. Unfortunatly any chance of ever trying to make a move on her would be a mistake since she’d say something to Sam and my wife being her sister, she’d squel to her and I’d be in a world of trouble.
“Were going out on the balcony to have a cigarette. Coming Alivia?” Sam asked as she searched through her purse for her cigarettes. My wife and I didn’t smoke so our house was smoke free.
“Yeah, I’m coming.” Aliva handed me the bowl and smiled then walked out onto the porch. As I poured the chips, i heard and felt the counter vibrate. Confused i looked around till I saw Alivia’s phone spinning and vibrating on the counter. Curious, I grabbed it and and saw that she’d received a text from her friend Betsy who was another of Sam’s friends who frequantly came over. Ignoring the text, I went to her other text messages and saw that the last person Alivia had texted was Sam. Curious, I opened the text and gasped.
(Alivia) Thanks now all I have to worry about is whether Jason will kiss back.
Not sure if I’d read it right, I read it three more times. Was Alivia really saying what I think she was saying. I quickly checked to see if anyone had noticed what I was doing. They were all still on the porch smoking. I had at least 3-4 more minutes to snoop. I scrolled down the screen to the begining of the conversation.
(Sam) So you’re coming?
(Alivia) yeah u and john picking me up at 5?
(Sam) yes we leaving his house in a bit
(Alivia) how was he?
(sam) lol i dont kiss and tell
(Alivia) u mean fuck and tell slut 🙂
wow, danielle had said they had made out, not fucked. It was a little weird to me to know that my brother was fucking my wife’s sister. I read on, eager to find out what they’d said about me
(Sam) shut up skank lol
(Alivia) can i ask you something important sam?
(Sam) if it is what you asked before no. please she is my sis
(Alivia) but sam i just want to have a little fun its not like im going to steal him from your sis.
Now we’re talking.
(Sam) its just weird
(Alivia) no it not it just sex
I couldn’t believe how blunt she was. I still could not believe what I was ready. The sexy cock stirring 17yr old piece of ass out on the porch that i’ve been fantisizing about since the day i met her was actually begging my wife’s sister not to say anything if she fucked me. This was too good to be true.
(Sam) what?! youre crazy you know what
(Alivia) please just let me try and dont say anything
(Sam) fine if he gunna cheat let him cheat
(Alivia) and youll be neutral and not say anything
(Sam) yes i promise
(Alivia) Thanks now all I have to worry about is whether Jason will kiss back.
I heard the porch door sliding open so i quickly hit the END button on the phone to closed the message screen and set it on the counter.
