Fucked my girlfriend’s friend after threesome (mff)

So it was my girlfriend’s birthday a few weeks ago, and big surprise, she got pretty hammered. She’s about 5’8″, D cups, blonde and very pale. I’m 6’2″, also blonde, with a 7-8 inch cock that is a little bit less thick than a toilet paper roll.

We went out for dinner on Saturday, and her friend came along with us. She’s about the same size as my girlfriend, with slightly smaller breasts and black curly hair with an adorable doe face. She’s a classic slut, got pregnant in high school by her older drug dealer and now she’s a single mom. We are all in our early twenties.

Over the course of the night my girlfriend got progressively more smashed, and I kept seeing her whisper to her friend and then they would giggle and look at me. I’d talked about bringing in a third with my girlfriend but we hadn’t discussed it in a while. At one point we were at a bar after dinner and my girlfriend was showing her friend something on her phone… it was a picture of her sucking my cock and her friend looked really turned on and she started giving me the eyes. My girlfriend came up to me when her friend went to the bathroom and asked me if I wanted to fuck them tonight, of course I agreed.
