Like a dumb ass, I told her that I wanted to lay naked with her. She didn’t complain and started undressing. (Wait: there’s one more thing: I have...a lingerie fetish. Not other people’s lingerie, just my sister’s.)Back to the story… When she peeled off her shirt and pants, I started in by caressing the outside of her bra.
