Sina still looked like the day she first submitted to her Master, only her behaviour had changed. She had spent so much time on all fours it seemed od... to her to walk up straight outside and she seemed to always wait for a word from her Master to sink on her knees again.Tonight sina had a leather hood put on her head with holes for her eyes and mouth. A leather straight jacket held her tightly restrained as she had to kneel and watch her sister wriggle in pain as their Master laid a horse whip. The cleavage she now sported made my dick rock-hard in an instant. Smiling at the obvious bulge in my pants, she said, “well, I guess you really do find me very attractive . . .” She unhooked her bra, let it slip from her tits and threw it on the floor, giving me my first look at her incredible boobs in all their naked glory. They were just a big saggy, but the sheer size of her mounds was amazing. Her areolae were huge and her large nipples were proudly erect. My eyes were simply glued to. I then thought, whatdid I do last night? I was about to ask when Josh said, "You were quite the lady last night.I'm sorry to say, one of the idiots in the bar put a pill in your drinksand you and Vicki were, well, pretty out of it in a matter of minutes.Josh and I helped you to our places for the night. I took off your dressto let you sleep and you pulled down your panties yourself in front ofme wanting to pee. You passed out on the bed and I helped you into bed.I didn't do a thing to you. The swollen pink lips glistened with her juices. As I watched my mother reached down and spread her inner lips with her fingertips and plunged two fingers within her pussy Then she withdrew her freshly-lubricated fingers to rub her clit. As she did this I could see and smell the wonderful scent of the juices on her fingers and I noticed for the first time that her knickers were drenched. In fact, some of her juices were now running down the inside of one of her thighs and the scent of her.
