Some years ago my sister-in-law was forced to live with us for about six months when a fire destroyed her apartment. I had always fantasized about her. Jen is a short, attractive woman in her early thirties.
I would masturbate as I thought of her fine ass. But mostly, I would fantasize about wearing her panties while jerking off. With her in the house I couldn't resist. I grabbed a pair and dashed to my bedroom. I put them on and was immediately rock hard. I pranced in front of the mirror and looked at my big hard on and I rubbed the fabulous panties until I exploded and watched the cum seep through the delicate material. I had more opportunities but those stories can wait.
