I slipped into the shower with my bestie's girlfriend, who drove me crazy with her big ass

Since my friend and I were staying in the same house, her girlfriend was always coming home and staying with us. The blonde lady was literally doing her best to get my eyes on her big ass. I couldn't say anything to my friend in case he misunderstood. This situation could not continue like this, because I had no patience left to endure it. Now her ass had become an obsession for me too. While we were alone at home, I was spying on her and looking at her ass. Today I even snuck into the bathroom while she was taking a shower and took a look at her voluptuous body. Her ass and breasts were perfect. He watched her for a while and was about to get fucked when he saw me. I said to myself, "Now I'm screwed." If my bestie caught wind of this, it could have been really bad. But luckily his girlfriend was a real badass. She invited me to the shower to lather her buttocks. I took off my clothes and lathered that ass I was dreaming of. Seeing that I was getting hard, the whore bent over in front of me and I thrust inside her. I leaned against her in the shower and made her cum on her beautiful face. I hope my friend doesn't find out that I fucked his girlfriend.
