Uncle Harry zooms the camera in on her tits and tells her to harden her nipples. It almost looks like time-lapse photography the way her nipples just expand until they're fully erect. I can't wait until the next time I see my sister so I can suck on those incredible tits. The view changes to a close up of her bald pussy and I hear uncle Harry tell her to lubricate her pussy without having an orgasm. Susan's pussy lips are thinner than they looked in the still picture but then as I watch, they just puff out, turn a brighter shade of pink, flutter open and start seeping juice....
