I surprised my girlfriend and her gay friend with a threesome while they were studying, leading to a wild anal session with a sex machine

I came home from work to find my girlfriend and her friend studying in the living room. I had a surprise for them - a brand new sex machine. I wanted to see how they would react to it. My girlfriend was excited and eager to try it out. She took off her clothes and let the machine do its job. The sight of her getting fucked by the machine was too much for her friend. He couldn't resist and joined in. The two of them were having fun, laughing and enjoying themselves. The machine was doing its job perfectly, fucking both of them hard and deep.
