Sister-in-law Sees my Cock pt. 1

I love this story cuz I’m not very big, but this is my first relationship where I’m the ‘big’ guy.

So a little back story. My Wife (Shannon) has a twin sister Emily. Thought they arent completely identical, they both look very alike. Pretty, brown hair, Big boobs, nice ass. Tho, Emily was a bit thicker / a little less pretty. Emily has been in a relationship with this guy I’ve known for a long time named Matt. We were both on the high school football and basketball team together and I’ve showered near him a couple times in the locker room and it’s pretty easy to tell he has a pretty small cock. For reference, I’m about 6 inches hard (pics on profile) 3 inches soft. The guy was maybe an inch and a half. I never said anything cuz it never really mattered to me and I figured he could have been a grower.

Fast forward 10 years and we are 28, and both Matt and I married our high school sweet hearts. Though I’ve experienced a couple girls in the past (brief break up), I knew that Emily and Matt never had a different sexual partner.

Last Christmas Emily and Matt stayed the night in our second bedroom after having dinner and drinks. Shannon and Matt end up passing out at 9 pm, and I decide to take a shower after a long night.

I came out to the living room in my robe and started watching tv. About half way thru some B99, Emily comes out and asks to join me cuz she couldn’t sleep. I said of course and she decides to sit across from me.

In the corner of my eye I can see that she’s looking over at me and trying to be sneaky. I just ignored it and watched the show. All of a sudden I feel a cool breeze right up my robe and realize my cock is just out in the open for Emily to see.

I look to see her leaning over trying to get a better view up my robe (most of the lights were off). I quickly sat up and apologized for ‘hanging out’ and she just smiled and said ‘no problem’.

Ten minutes later she suddenly turns to me and asks me ‘why were you hard?’

Me: (stunned) uhh… I wasn’t?

E: you had to be come on.

M: seriously, never been softer

E: hmm well I didn’t get a good look any ways.

M: you weren’t supposed to lol

Emily then just gets up and says ‘all dicks are basically the same anyways, I’m going to bed goodnight’

More to come. Have plenty with her.
