My neighbor replaced my sex machine so he could fuck me!

I caught my big-assed neighbor pleasuring herself with her sex machine, and as soon as she was a little distracted, I replaced her sex machine with my cock. She couldn’t notice the change since my cock is the same size; I just had to simulate the rhythm of her machine. After a few minutes, she realized, but it was obvious she wasn’t going to say anything since I’d already been penetrating her for a few minutes, and from her moans, it was more than clear that she liked my cock.
