She bit down on the pillow and quivered. Jake pinched her clit between his fingers and her head snapped up. She gave an unearthly moan and a stream of... liquid shot out of her pussy and soaked both their thighs and the bed. The pent-up semen spurted from his balls and his dick pulsated in her ass causing her to gush even more nectar. Sated, she fell forward. Jake followed, draped across her back. Jake started to get up but Debbie wouldn’t allow it. They rested like that for about ten minutes.. Occasionally one would try to get a glimpse of the other and moan softly. Their Master knew their juices were flowing freely in moments like these. And sina and sara knew that he knew. It was a part of their own special humiliation. sina and sara shared everything after all, for they were sisters.They had applied some time ago. Twins, who first admitted to themselves and then to each other what they craved. It took their Master a long evening with the cane to get them to admit that they tried. . she had fantasized about that sort of thing. Those of her girlfriends who had tried it either found it disgustingly dirty or raved about how utterly fantastic it was."Come on, baby. I know what I'm doing. You'll enjoy it as much as I will, maybe even more. I'm not gonna force you, but make up your mind. Either open up your ass for me or get the hell out of here."She had to choose. Now. She hesitated, then bent over.It stung a little going in. He had "lubed" himself up with soap, and it felt. She installed him on the blousing couch. Ohhh, it already had a dozen of her petticoat slips laid out, to follow his blouse worship. He put his wrists behind him to be ribboned together - how he loved that, since it meant he couldn't stop her from doing what she wanted with him - then she secured his ankles to the bar, spreading his legs wide."My, isn't my little boy helpless? His clitoris standing up in my presence. How polite. How eager, more like." She walked behind him, opened her closet.
