My Best Friend

So I’ve been friends with this girl since high school. I’ve know her going on 6 years now. We’ve always been there for each other. For each other’s break up, mental downs, and everything in between. Recently my girlfriend and I have stopped having sex ever since our kid was born and I’ve been so sexually frustrated. I wish I could use my friend as a fuck doll. She’s so fucking thick and has double D breast that are just suckable! Her ass is so fucking fat. I’ve smacked her ass before in front of my girlfriend and she didn’t mind only because my friend smacked mine first. God I just wanna see her titties bounce up and down as I thrust my cock deep inside of her. We had moments of ‘almost’ but nothing happened. I just wanna fuck.
