[M]y Birthday present [F]rom my GF.

I just turned 26 this month and my GF [28] gave me the best birthday present!
Before the dirty details of the story, a little bit about us. I’m 6’, athletic build and have an average 6.5” cock. My GF is curvy and a sex freak. She’s about 5’10” and is a 36 C with a nice round phat ass. Now on to what happened. We work in the same firm and that’s where the events of my birthday took place.

It all started with a joke. I had joked to her that she find a way to suck me off for my birthday and she was very enthusiastic about it as well. I didn’t give it much thought after that and my birthday came. On that fateful morning, I was doing my work as usual and I thought she was too. We were due for a meeting with the boss in about 15 minutes when she texted me that she was going ahead with my birthday wish. I was surprised but thought she was pulling my leg as there was no way it was happening In an office filled with so many people.
