My mother-in-law SURPRISES us, I never thought I could FUCK BOTH TOGETHER

Alone in the dining room, sitting on the sofa with my girlfriend a beautiful petite, very voluptuous and in good shape, with a huge and very round butt. We were trying not to make noise so that his stepmother wouldn't catch us, because the idea was to right there without him noticing.But in the middle of the kiss he surprised us. He sent her straight to her room to be alone with me and ask me what I had with her stepdaughter. She was a tremendous tanned blonde, with huge tits that drove you crazy. After asking me a couple of questions, out of nowhere he rushed at me and gave me a terrible kiss. He threatened me that he was going to tell my girlfriend that I had looked for her, but nothing to do with it, she was the one who got on top of me.That's when my girlfriend comes out, catches us with the stepmom and it all ended in a reheated threesome, totally unexpected and real. I ended up both of them at the same time and they ate everything to the last drop.
