Sister-in-law sees my cock part 4

Sister-In-Law sees my cock pt. 4

One day I decided to go on a bike ride for a quick workout when I get a text from Shannon (my wife) asking me to pick up Em (SIL) from the airport at 3pm. Matt was out of town on business and Shannon got stuck at the office.

The airport is an hour away from where we live so I was kinda annoyed but agreed. I throw on my tightest spandex to show off my bulge and head on over to pick her up. As I’m approaching the airport I position my dick/bulge so that she has a clear view of it once she entered the car.

She jumped in the car with her huge tits swaying around. We start talking about her trip when all of a sudden she stopped mid-word. I look over and she’s looking at my cock. She recomposes herself and goes on a story that I really wasn’t paying attention to.

About half way home she said thanked me and told me she really appreciated the ride, and Uber would have cost her a fortune.

I said nbd but the rule in this car is cash, gas, or ass as a joke. She laughed and said “I don’t got cash or gas, and you certainly can’t have his ass”, I reply with “alright we’ll have to work something out then”.

A few moments of silence, when she suddenly says “how about a HJ?”? I do a double take and say “what?”

E: I’ll give you a HJ right now if you can keep a secret

Me: funny joke

E: I’m serious, I don’t mind.

M: I mean…. I was kidding you dont have to do anything for the ride

E: lol I know! I just want to feel a big cock like that in my hand.

M: …. sure as long as you don’t tell Shannon or Matt.

With that she leaned over and grabbed my hardening cock

E: let’s get these shorts off then

*I pull them down while driving

Em immediately grabs my cock and just holds it at the base

E: Shannon is so lucky. This thing is as thick is as my forearm.

With that she just started giving my the most sensual HJ of my life. Slowly working my shaft and focusing on right below my head.

E: you’re so hard holy shit. This is easiest the biggest cock I’ve ever seen. Matt is like half your size.

Emily then grabs some lotion and continues stroking my cock.

M: this feels so good… I’m so close

Em proceeds to pull off her top

E: your cock is so big and hard. I can’t believe how much you’re throbbing in my hand. I want this thing inside of me.

I couldn’t hold it anymore. I told her I was going to cum and she just kinda looked panicked like she didn’t think that far ahead.

I was about 10 seconds from erupting when she said “okay remember don’t tell anyone” and she brings her head down to my cock and tells me to cum in her mouth.

I didn’t need telling twice and right when I felt lips wrap around my cock I unload.

She cleans herself off and as we pull up to her house she says “thanks for the ride” then says quietly “and for letting me play with a real mans cock” and just saunters off to her front door.
