My Boyfriend Caught Me Fucking His Best Friend!

My boyfriend went to the supermarket just as his friend was dropping by, he walked in while I was masturbating and I couldn't resist fucking him, I'd heard from a friend he had a big cock and that is my biggest weakness, especially with my small dicked boyfriend, who can't even satisfy me in any way. He ate my pussy so good and then I finally got to deep throat his big cock! He was so long it hit the back of my throat so easily I loved it, felt like I had a G spot in my throat. He started fucking me so good when my cuck of a boyfriend came home and walked in on us, but I had already submitted to his friend now so I didn't bother stopping. It was so good we didn't even care, we just started humiliating him! He gave me a HUUUUUUUUGE creampie and made my bf eat it. UPDATE: Now we're dating and he is our cuck.
