There was no sign of them. I quietly opened the door. They were upstairs. The door to the main room, our bedroom, was closed. I went to the kids room ...nd opened the patio. The adjoining balcony led to our room. The sliding door was wide open. I glanced in. There she was on the bed with a guy on top of her. The cheating slut! They were making out passionately. Her robe had come open and his hands were all over her breasts and legs. She wrapped her legs tightly around his back. I could hear her. She squirmed involuntarily, as Emma worked the dildo ever so stealthily into place. Finally, she pushed her hips steadily forward until the massive cock penetrated Amy’s unsuspected love canal, and slipped inside. “WHOA! WHAT THE FUCK, EMMA?!” Amy exclaimed, as she rapidly became aware of her older sister’s intentions, but it was too late. Emma had Amy’s small round ass tightly in her grip, and she began moving the larger rubber shaft in and out of her wide-stretched pussy. “GOD ALMIGHTY, EMMA,. I saw on her bed there was a large dildo, it was wet and Mary was picking it up."I saw you staring, want a shot?"I ripped off my tight jeans and Mary helped me take off my silky panties."To use it, you must be completely naked"I saw that she was removing her bra as she said it, she came over and unclipped me from behind. There we were, two naked wet schoolgirls about to mastrubate togethor it was like something out of a porno. I lay down on her bed with her hot body next to me and she helped me. Just before I left the bathroom,I wondered if the machine had given me a layer of makeup or somethingalong with those clothes (and the bra, which had no equivalent in theitems of clothing I was wearing before); I rubbed at my cheeks and lipsand didn't smear anything, so I guessed I didn't need to clean anythingoff before bed. I'd have to get Sophia to teach me about that sometime.Soon I was in bed, but my thoughts were racing too much to sleep fora while. I was alternating between being.
