What does Josh do?

Leave them be

Although he was getting horny watching them, Josh thought it would be rude to interrupt. He would find some other way to find release. Perhaps one of his neighbors could help, there were a couple of girls who he had been on friendly terms with and since that now meant that they might have sex with him and since they would now be hotter than they had been it seemed like a reasonable idea.

He walked into the kitchen and saw the back what he at first remembered as a better looking version of his parent's friend Lisa, but then realized was his 'other mother', Elena's mother and his family's second wife. In the new reality she had married his parents instead of just being the bridesmaid. This 'realization' also bright back memories of Lisa's sex lessons which she had given him when he turned 18, which made him even more aroused. He wondered wither she would be willing to help him out now or whether he should try to find someone outside his family.
