Backdoor lover

My sister Becky knows I see David and sometimes gives me a good alibi, but on the condition that I give her all the juicy details. She is fascinated at my description of David’s organ and I’m sure that one of these days she’s going to ask for the chance to experience that big thing. Right now, though, she marvels that something so big can fit into a small hole, puss or ass. I’ve already loaned her a few of my anal toys.
I bet David would just love to nail both of us!
