To fetch another toy

A few minutes later Susan re-entered the bedroom, but now she was not fully naked. She still had no clothes on but strapped around her waist was a harness to which she had attached a 6" dildo. It was not exactly a slim one but you could see it was meant for anal play as it was smooth.

Sarah and John were so engrossed in pleasuring each other they had not even noticed that Susan had left the room. John had noticed the lack of something in his ass which disappointed him a little; but Susan was about to put that right. Susan walked over to the bed and lifted John's legs over her shoulders as she knelt on the edge of the bed this exposed John's asshole nicely.

Sarah stopped sucking John's cock so she could help her Step-mum put the now lubricated dildo into John's ass. Together they helped it go in and Susan got into a rhythm pushing the dildo in and out of John's now expanding asshole. Sarah now moved positions so she could once again suck John's cock, this time she was off to the side so John could see Sarah's head moving up and down on his cock and just behind he could see his step-mum pumping in and out of his ass. If John looked to his right there was a full length mirror which happened to be positioned to give him a good view of the dildo going back and forth. With each stroke he could feel himself getting closer and closer to an earth shattering orgasm. With both girls working on him he knew he wouldn't last long.
