I let my gf dog fuck me

I don't why I did it, but i couldn't help it. Fido was just there and he had such a big and meety cock. When my gf left to get food, i just couldn't take and started sucking his cock, his red rocket came out and I could taste his precum after sucking for 5 minutes. Before he came i stopped and pulled down my pants and let him go to town on my boipussy. He fucked me so hard and I was already dripping semen from my dick. We were fucking for around 20 minutes and then my gf walked in and saw us. She kicked me out and now I miss her. I just want her to forive me, and let me come back. I love her soooooo much, please forgive me anna.
