His best friend

Josh recognised the background of that dick pic! Without a doubt that was his best friend Steve's room. He scrolled further back, passing more pictures of his mom posed seductively, intermixed with pictures of hard abs and harder dicks until he found a pic that confirmed his suspicions. Sent only a week ago was a picture of his oldest and closest friend, completely naked, in Josh's bathroom. Josh checked the timestamp and realised that was the day Steve had come round to hang out before a big party. He must have taken those pictures when he went to "get ready".

The betrayal of years of friendship stung as Josh realised what his friend had been doing behind his back but another part of him was kind of happy it was Steve. He was a nice guy, the sort who would treat his mom right and it hadnt escaped Josh's notice he was clearly blessed in the dick department.

Josh considered his options, he could cancel on Steve but that seemed callous this close to the date. He could go in place of his mom and ensure it went well, or intentionally ruin it for them. Alternatively he could just not get involved, he could swap back and let his mom go on the date and see how things played out.
